Abstract:
A system and method for correcting brake knockback in a vehicle disk brake system. Brake knockback can occur when a vehicle is driven through an aggressive turn or in other environments that exert a significant amount of lateral force on the vehicle's wheels. This can cause the rotors to deflect and push brake pistons into retracted positions, where they remain even after the vehicle exits the turn. According to one embodiment, the present method first estimates or predicts brake knockback by using lateral acceleration readings from the vehicle and a brake knockback model, and then corrects brake knockback by generating command signals for a hydraulic pump.
