Abstract: A redundant parking brake apparatus is provided for a vehicle having components of a parking brake system. The redundant parking brake apparatus comprises a first parking brake controller arranged to (i) monitor a first signal indicative of a request to apply parking brakes of the vehicle, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply the parking brakes in response to receiving the first signal. The redundant parking brake apparatus also comprises a second parking brake controller arranged to (i) initiate a timer counter in response to receiving the first signal, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply the parking brakes when the timer counter has reached a predetermined count.

Abstract: A park brake controller and method are provided for control verification handling of an external park brake request. In one embodiment, a park brake controller comprises one or more processors and a non-transitory computer-readable medium storing program instructions. The program instructions, when executed by the one or more processors, cause the one or more processors to: receive a request to park a vehicle, wherein the request is associated with a control level; receive information about a speed of the vehicle; and determine an action to take in response to the request based on the control level of the request and the speed of the vehicle. Other embodiments are provided.

Abstract: A park brake controller with multiple communication channels and failsafe methods for use therewith are provided. In one embodiment, a park brake controller is provided comprising a plurality of transceivers. In response to at least one of the plurality of transceivers not being able to receive, from a communication network in a vehicle, a park brake request and vehicle sensor data, the park brake request and vehicle sensor data are sent in a different, more-robust form to be received by another one of the plurality of transceivers. Other embodiments are provided.

Abstract: A braking controller causes a tractor protection control module in a tractor to prevent air flow from an air reservoir to a gladhand when the braking controller determines that the trailer is not pneumatically coupled with the gladhand. This prevents air from being vented out the gladhand when the tractor's service brakes are applied. The braking controller can detect pneumatic discontinuity, for example, by receiving a notification from a parking brake controller or from a pressure sensor in the tractor protection control module.
