摘要： Various embodiments of a controller for controlling at least one solenoid comprise a first electrical connector for electrically communicating with a vehicle communications bus; a second electrical connector for transmitting messages to a plurality of solenoids; and a processor having control logic. The control logic is capable of associating each of a plurality of solenoids with a vehicle function when the plurality of solenoids are in electrical communication with the controller; receiving a control message at the first electrical connector in a first format to enable a first vehicle function; and electrically communicating a control message in a second format at the second electrical connector in response to receiving the control message in the first format to control one of the plurality of solenoids associated with the first vehicle function.

摘要： Various examples of park brake interface modules which are utilized as human machine interfaces (HMI) in vehicles are provided. In one example, a park brake interface module for a vehicle includes an actuation member mounted to an electromechanical switch to actuate the park brake. The actuation member includes a finger pad opposite the front surface and the actuation member is movable between a brake apply position and a brake release position to actuate the vehicle park brake. In another example, the actuation member is pivotally mounted to the electromechanical switch device and the actuation member is pivotable between the brake apply position and the brake release positions to actuate the park brake.

摘要： A parking brake apparatus for a vehicle includes a parking brake controller controlling a parking brake system and arranged to obtain one or more input signals indicative of one or more actions from one or more vehicle systems other than the parking braking system. The parking brake controller is also arranged to provide one or more control signals to be applied to components of the parking brake system to apply parking brakes based upon an adaptive time delay to prevent a vehicle rollaway when the one or more input signals are indicative of the one or more actions meeting respective one or more predetermined conditions.

摘要： A system controlling an electronic parking brake of a vehicle includes an input device receiving an input pattern from an operator and a parking brake controller receiving the input pattern from the input device. The parking brake controller determines if the input pattern is a respective predetermined pattern for setting the electronic parking brake to one of a primary mode and a secondary mode. If the parking brake controller determines the input pattern is the predetermined pattern for setting the electronic parking brake to the secondary mode, the parking brake controller transmits an electronic control signal for releasing the electronic parking brake until a subsequent input pattern received by the input device is the predetermined pattern for setting the electronic parking brake to the primary mode.

摘要： An apparatus for controlling a trailer parking brake status indicator in a tractor is provided that allow an operator to deactivate the indicator when the tractor is operating without a trailer using a pre-existing operator interface. The apparatus includes means for determining whether a trailer is coupled to the tractor and a controller configured to execute, when a determination whether the trailer is coupled to the tractor cannot be made, a process for controlling activation and deactivation of the indicator. The process includes determining whether a speed of the tractor meets a predetermined condition relative to a predetermined speed. The process further includes monitoring, after determining that the speed of the tractor meets the predetermined condition relative to the predetermined speed, for an activation command to activate a parking brake on the trailer. The process further includes deactivating the trailer parking brake status indicator responsive to the activation command.

摘要： A parking brake controller comprises at least one input for receiving a signal indicative of at least one vehicle factor, a control input for receiving a request to unpark the vehicle, an output for transmitting a control signal to a parking brake valve and control logic. The control logic determines the at least one vehicle factor indicates the vehicle can be unparked, determines an unpark request has been received, and transmits a control signal to the parking brake valve only in response to the unpark request being received while the at least one vehicle factor is being met.

摘要： A system for controlling compounding in a vehicle brake actuator includes first and second valves configured to control, respectively, a first fluid pressure in a parking brake chamber of a brake actuator that acts against a spring force applied by a spring of the actuator to a pushrod of the actuator and a second fluid pressure in a service brake chamber of the actuator that applies a fluid force to the pushrod. A controller is configured to receive first and second fluid pressure signals indicative of the first and second fluid pressures, determine a total brake actuator force applied to the pushrod responsive to the first and second fluid pressure signals and control at least one of the first and second valves responsive to the total brake actuator force to adjust a corresponding one of the first and second fluid pressures and thereby obtain an adjusted total brake actuator force.

摘要： Various examples of park brake interface modules which are utilized as human machine interfaces (HMI) in vehicles are provided. In one example, a park brake interface module for a vehicle includes a park brake switch device to actuate the park brake. The park brake switch device is capable of actuating the vehicle park brake in a brake apply mode upon receipt of a pinch signal. In another example, the park brake interface module includes a park brake switch device which is capable of actuating the vehicle park brake in a brake release mode upon receipt of a reach signal. In operation, the electronic interface module and park brake switch devices allow the operator to apply or release the vehicle park brakes according to memorable mnemonics, for example. “pinch to park” and “reach to release.”
