A system and method of controlling individual trailer brakes on a towed trailer supporting numerous fault tolerant behaviors including activating each operational brake when a brake is shorted. System operates in multiple modes where it operates with traditional brake controllers, operates in a degraded braking mode without a brake controller and in the preferred mode it retrieves vehicle information from tow vehicle and then communicates with a brake actuator controller over the trailer brake wire. When braking system includes wheel sensors traditional antilock releases are provided and unlike other braking systems this brake actuator controller can maintain wheel speeds below the trailer speed reducing or eliminating periodic wheel releases. System also diagnoses the mechanical operation of the trailer brakes including; identifying when brake adjustment is required, when brake friction surfaces are degrading, as well as diagnosing sensors, braking signals and brake actuator interfaces.

This application provides a torque compensation method for a vehicle, a torque compensation apparatus of a vehicle, and an associated computer-readable storage medium. The torque compensation method includes: when a vehicle control module determines that the vehicle is in a sliding state during a brake idle stroke, obtaining, by the vehicle control module, a pressure of a brake master cylinder of the vehicle, and controlling a motor of the vehicle based on the pressure of the brake master cylinder to output a compensation torque. In this application, a range of the brake idle stroke of the vehicle can be precisely determined, so as to control the motor of the vehicle to output the compensation torque in a timely manner, thereby effectively suppressing sliding during the brake idle stroke of the vehicle and ensuring safe driving.
