Overview

The Bendix Intellipark Electronic Parking Brake System is an electronically controlled pneumatic system that replaces traditional red and yellow push-pull parking-brake control valves with electronic switches.

The system continues to operate the vehicle’s pneumatic spring brakes. However, it uses electronic controls, vehicle-status information, and electropneumatic valves to determine when the tractor and trailer parking brakes should apply or release.

Its primary safety function is rollaway mitigation. If the driver fails to apply the parking brakes and the system detects specified conditions associated with the driver leaving or not properly controlling the vehicle, Intellipark can automatically apply the parking brakes.

The system also provides Smart Unpark functionality. When the required interlock conditions are satisfied, the driver can release the parking brakes using the electronic switch. Inputs may include door position, seat-belt status, vehicle movement, brake status, and other vehicle-specific information.

LED indicators communicate whether the tractor and trailer brakes are applied or released. An available Intellipark Display Unit can provide additional system messages, alerts, operating status, and interlock information.

Bendix describes Intellipark as a rollaway-mitigation system designed for tractor-trailers, single-unit trucks, motor coaches, and school buses. Bendix Intellipark product information

How the Brake Component or System Works

Intellipark electronically controls the pneumatic valves that apply and release the vehicle’s spring brakes. The driver uses dash-mounted electronic switches instead of mechanically operated push-pull valves.

When the driver requests parking-brake application, the Dash Electronic Control Unit sends an electronic command to the Park Valve Module. The valve module exhausts air from the appropriate spring-brake circuit. The spring-brake actuators then use their internal mechanical power springs to apply the brakes.

When the driver requests parking-brake release, the controller first evaluates the applicable interlock conditions. If the vehicle is ready to move, the Park Valve Module supplies air pressure to the spring-brake chambers. This compresses the power springs and releases the parking brakes.

If Intellipark determines that an unintended rollaway may be developing because the driver failed to set the brakes, it can automatically command parking-brake application.

The system’s exact logic depends on the vehicle manufacturer and configuration. It may evaluate inputs such as:

  • Driver-door position
  • Seat-belt status
  • Vehicle movement
  • Service-brake application
  • Transmission state
  • Ignition state
  • Available air pressure
  • Tractor or trailer connection status

Intellipark does not replace the spring brakes. It replaces and expands the control method used to apply and release them.

Position and Function Within the Brake System

Intellipark is installed between the driver’s parking-brake controls and the vehicle’s pneumatic spring-brake circuits.

The driver interface is located in the cab. The electronic switches send requests to the Dash Electronic Control Unit rather than directly controlling air pressure.

The controller processes the driver’s request and information received from other vehicle systems. It then commands the Park Valve Module to apply or release the appropriate pneumatic circuit.

On a tractor, the system may control:

  • Tractor spring brakes
  • Trailer spring brakes
  • Trailer air supply
  • Rollaway-mitigation functions
  • Smart Unpark functions
  • Optional trailer-brake release logic

On a straight truck or bus, the system generally controls the vehicle’s spring brakes without a separate trailer circuit unless the chassis is equipped for towing.

Common Specifications

  • System Type: Electronic parking-brake control
  • Brake Actuation: Pneumatic spring brakes
  • Driver Control: Electronic switches
  • Status Display: Integrated LEDs and optional display unit
  • Primary Controller: Dash Electronic Control Unit

  • Fail-Safe Medium: Mechanical spring-brake force
  • Diagnostics: Electronic diagnostic trouble codes and Bendix-compatible service tools
  • Installation: Original-equipment and vehicle-specific
  • Foundation-Brake Compatibility: Compatible air-braked vehicle configurations

Exact switch arrangement, valve module, software, wiring, interlocks, pneumatic connections, and optional functions depend on the vehicle manufacturer and model.

Operating Specifications and Performance

Intellipark requires adequate air pressure, electrical power, valid input signals, and functional pneumatic components for normal parking-brake release.

Parking-brake application relies on exhausting air from the spring-brake circuit. The spring inside each actuator then supplies the mechanical force needed to apply the foundation brake.

Normal release requires sufficient pressure to compress the power springs. Low system pressure may prevent the brakes from releasing even if the electronic control system accepts the driver’s request.

The system continually monitors operating information and communicates brake status through its LEDs or display. A steady, flashing, or unexpected indicator may communicate a normal transition, an unmet interlock condition, or a system fault. Drivers must follow the exact vehicle operator’s manual because indicator patterns can vary by application.

Intellipark performance depends on:

  • Adequate air-system pressure
  • Correct spring-brake operation
  • Functional Park Valve Module
  • Reliable electrical power
  • Valid sensor and interlock inputs
  • Correct controller software
  • Proper vehicle-network communication
  • Correct pneumatic plumbing
  • Functional foundation brakes
  • Proper parking-brake adjustment and maintenance

Braking Performance and System Integration

Intellipark does not create additional foundation-brake torque. Parking-brake holding ability remains dependent on the spring-brake actuators, brake chambers, slack adjusters, calipers or cam brakes, friction material, drums or rotors, tires, and road surface.

The system improves parking-brake control by adding electronic logic and automatic functions. It can recognize certain operating conditions that a conventional manual push-pull valve cannot evaluate.

Integration may include communication with:

  • Engine controller
  • Transmission controller
  • ABS or stability controller
  • Instrument cluster
  • Driver-door sensors
  • Seat-belt system
  • Vehicle-speed network
  • Bendix advanced driver-assistance technology
  • SafetyDirect fleet-information services

The system must distinguish between an intentional parking-brake request, a valid release request, an interlock that has not been satisfied, and a potential rollaway event.

Air Supply, Controls, and Electronic Integration

Intellipark combines electronic commands with pneumatic brake control. Electrical switches tell the controller what the driver has requested, while the Park Valve Module directs compressed air through the parking-brake system.

The system may interact with:

  • Air compressor
  • Air dryer
  • Supply reservoirs
  • Primary and secondary reservoirs
  • Spring-brake reservoirs
  • Spring-brake chambers
  • Tractor-protection valve
  • Trailer-supply circuit
  • ABS controller
  • Stability-control system
  • Engine controller
  • Transmission controller
  • Instrument cluster
  • SAE J1939 communication network
  • Bendix diagnostic software

The electronic system does not eliminate pneumatic fail-safe operation. If air pressure falls below the level needed to contain the spring brakes, the mechanical power springs can apply the brakes.

Bendix states that parking-brake actuation remains possible without electrical power. The exact degraded-mode behavior and driver procedure must be confirmed using the vehicle-specific operator’s manual.

Installation, Adjustment, and Brake Balance

Intellipark is engineered as part of the complete vehicle. Installation requires the correct electronic controller, switches, Park Valve Module, pneumatic circuits, wiring, software, interlocks, and vehicle-network integration.

It should not be treated as a universal electronic switch that can replace a conventional dash valve without additional engineering.

Correct system installation depends on:

  • Vehicle manufacturer
  • Chassis model
  • Model year
  • Tractor or single-unit configuration
  • Air-brake system layout
  • Spring-brake circuit
  • Trailer-control system
  • Electrical architecture
  • Network communication
  • Transmission type
  • Door and seat-belt inputs
  • Approved controller software
  • Correct valve-module plumbing

The foundation brakes must also be correctly adjusted and balanced. Intellipark can command brake application, but it cannot compensate for worn friction material, excessive chamber stroke, damaged spring brakes, seized components, or contaminated braking surfaces.

Following repairs, technicians should verify tractor and trailer parking-brake operation, switch response, LED status, interlock behavior, diagnostic codes, air leakage, and proper brake holding.

Foundation Brake, Axle, and Wheel-End Compatibility

Intellipark controls the vehicle’s spring-brake circuits and can work with approved air-disc or S-cam drum-brake configurations.

Compatibility depends on:

  • Spring-brake actuator specification
  • Foundation-brake type
  • Axle arrangement
  • Tractor or straight-truck configuration
  • Parking-brake circuit design
  • Brake chamber size
  • Park Valve Module configuration
  • Trailer air-supply system
  • Vehicle electrical system
  • Controller calibration

The electronic control system cannot make an incompatible or improperly maintained foundation brake safe. All wheel-end components must meet the vehicle manufacturer’s specifications.

Common Applications

  • Class 8 highway tractors
  • Medium-duty trucks
  • Heavy-duty straight trucks
  • Vocational trucks
  • Delivery vehicles
  • Refuse trucks
  • Construction trucks
  • Utility vehicles
  • Motor coaches
  • Transit buses
  • School buses
  • Emergency vehicles
  • Specialty commercial vehicles
  • Air-braked towing vehicles
  • Vehicles with frequent stop-and-exit duty cycles

Vehicle and Brake-System Compatibility

Bendix Intellipark is available on selected factory-built commercial vehicles. Compatibility depends on the manufacturer, model, production date, chassis, air-brake system, transmission, cab electronics, and selected option package.

As of late 2025, Bendix announced factory availability for Kenworth trucks and Peterbilt heavy-duty, medium-duty, and Model 520 vehicles. Availability for an individual vehicle must still be verified through its build information.

Intellipark may be configured for:

  • Tractor-trailers
  • Single-unit trucks
  • Motor coaches
  • School buses
  • Vocational vehicles
  • Other approved air-braked chassis

A truck cannot be assumed to have Intellipark because it has electronic stability control, Bendix ABS, or Bendix Wingman Fusion. The system must be confirmed from its electronic switches, component labels, vehicle build sheet, or diagnostic information.

Driver and Operator Experience

Intellipark replaces the traditional parking-brake knobs with electronic switches. The switches retain familiar colors, symbols, and identification but require less physical effort to operate.

LED indicators allow the driver to check parking-brake status at a glance. An available display can communicate system messages, alerts, and reasons why an unpark request has not been accepted.

Before leaving the driver’s seat, the driver should still:

  • Bring the vehicle to a complete stop.
  • Apply the parking brakes.
  • Place the transmission in the required position.
  • Confirm the brake-status indication.
  • Shut down or secure the vehicle as required.
  • Use wheel chocks when required.

Drivers should not intentionally depend on automatic rollaway mitigation instead of setting the parking brakes.

Operators should report unexpected brake application, failure to release, flashing indicators, status disagreement, fault messages, air leakage, or changes in switch operation.

Maintenance and Ownership Notes

  • Inspect electronic parking-brake switches.
  • Check LED indicators during startup.
  • Verify the displayed brake status.
  • Test normal tractor parking-brake application.
  • Test trailer parking-brake application where equipped.
  • Verify Smart Unpark operation.
  • Inspect Park Valve Module air connections.
  • Check pneumatic lines for leaks and abrasion.
  • Inspect wiring harnesses and connectors.
  • Check electrical grounds and supply voltage.
  • Retrieve and document diagnostic trouble codes.
  • Verify door-position sensor operation.
  • Check seat-belt-status input.
  • Inspect vehicle-network wiring.
  • Maintain correct reservoir pressure.
  • Inspect spring-brake chambers.
  • Measure chamber stroke where applicable.
  • Maintain foundation brakes.
  • Confirm trailer-supply and protection-system operation.
  • Check current recall and product-action information.
  • Use Bendix and vehicle-manufacturer service procedures.

Common Brake-System Problems

  • Parking brakes will not release: Low air pressure, an unmet interlock, an active fault, a failed switch, Park Valve Module malfunction, wiring damage, or a spring-brake problem may prevent release.
  • Parking brakes will not apply by switch command: Electrical power loss, controller failure, valve-module problems, wiring faults, pneumatic restrictions, or incorrect system configuration may be responsible.
  • LED indicator flashes: The system may have detected a fault, rejected a request, or identified an incomplete operating condition. The vehicle-specific operator’s manual should be consulted.
  • Brake-status indication is incorrect: A switch, controller, valve, wiring circuit, network message, or pressure-related input may not agree with the actual brake state.
  • Smart Unpark request is rejected: The driver door, seat belt, service brake, transmission, air pressure, or another required condition may not satisfy the programmed interlock logic.
  • Unexpected parking-brake application: The system may have detected a rollaway-risk condition, lost a required input, experienced low pressure, or recorded an electronic or pneumatic fault.
  • Trailer brakes remain applied: A trailer-control fault, insufficient air pressure, Park Valve Module problem, damaged line, trailer valve fault, or disabled optional release function may be responsible.
  • Air leakage: Leaks may occur at the valve module, fittings, hoses, spring-brake chambers, trailer connections, or other pneumatic components.
  • Communication fault: Damaged data-network wiring, poor connections, low voltage, failed modules, or incompatible software may interrupt system communication.
  • Repeated fault after component replacement: The original problem may involve wiring, calibration, software, connector condition, pneumatic plumbing, or another vehicle module.

Safety and Service Precautions

Intellipark controls powerful spring brakes and must be treated as a safety-critical electronic and pneumatic system.

Before service:

  • Park on a level surface.
  • Apply the parking brakes.
  • Block the wheels.
  • Follow approved lockout procedures.
  • Drain or isolate air pressure when required.
  • Disconnect electrical power when directed.
  • Confirm actual brake condition rather than relying only on the display.
  • Retrieve diagnostic codes before disconnecting components.
  • Use vehicle-specific Bendix service information.

Automatic parking-brake application can occur when the system detects configured conditions. Technicians must remain clear of brake chambers, pushrods, slack adjusters, calipers, wheels, driveshafts, and other components that may move.

Never work beneath or around a vehicle secured only by its parking brakes. Use properly rated supports and wheel restraints.

If the electronic system is unavailable, follow the vehicle manufacturer’s approved procedure for securing, moving, or towing the vehicle. Do not assume a switch command has applied the brakes unless the vehicle’s actual condition has been confirmed.

Comparison to Similar Equipment

Compared with conventional red and yellow push-pull parking-brake valves, Intellipark uses electronic switches and a controller to operate the pneumatic spring-brake circuits. This makes automatic interlocks and rollaway-mitigation functions possible.

Compared with the Bendix ESP Full-Stability System, Intellipark primarily manages parking-brake application and release. ESP manages vehicle stability during motion through engine-torque reduction and selective service-brake intervention.

Compared with the Bendix SR-7 Spring Brake Modulating Valve, Intellipark is a complete electronic parking-brake control system. The SR-7 is a pneumatic valve used in specific spring-brake control and modulation functions.

Compared with a mechanical parking-brake control, Intellipark can evaluate driver and vehicle inputs before releasing the brakes and can automatically apply them under certain rollaway-risk conditions.

Regulatory and Compliance Notes

Intellipark does not relieve the driver of responsibility for securing the vehicle. Drivers must follow federal, state, provincial, local, employer, and site-specific parking procedures.

Required procedures may include:

  • Fully applying the parking brakes
  • Placing the transmission in the required position
  • Shutting down the engine
  • Removing the ignition key
  • Using wheel chocks
  • Verifying that the vehicle remains stationary
  • Following loading-dock restraint procedures

The parking-brake system must hold the vehicle under applicable inspection and operating requirements. Electronic controls do not compensate for worn foundation brakes, insufficient spring force, contaminated friction surfaces, overloaded vehicles, or inadequate tire traction.

Vehicles involved in earlier Intellipark product actions should have their recall status verified. A safety recall or product-action remedy should only be performed using approved parts, software, and procedures.

Modifying the parking-brake controls, interlocks, pneumatic plumbing, or software may affect regulatory compliance and vehicle certification.

Real World Operating Notes

Intellipark can be particularly valuable in operations where drivers repeatedly enter and exit the cab. Refuse collection, delivery work, utility service, school transportation, and vocational operations can involve frequent stops where forgetting the parking brake creates significant risk.

The electronic switches eliminate the physical kickback sometimes experienced with conventional pneumatic dash valves. Their LED indicators also provide a clearer visual indication of brake status.

Auto Trailer Brake Release can help when a driver moves a combination vehicle while the trailer parking brakes remain applied. Automatically releasing the trailer brakes under approved conditions may reduce tire flat-spotting, brake damage, wheel-end heat, and downtime.

Drivers should never intentionally test rollaway mitigation by leaving an unsecured vehicle. System verification should be performed only through approved diagnostic and service procedures.

If switch indication and actual vehicle behavior disagree, the vehicle should be secured immediately and removed from service until the cause is identified.
