ABSTRACT:
An apparatus for use with an automotive vehicle supported on traction and follower road wheels to control the braking forces applied to the respective road wheels. A target vehicle deceleration is calculated based on a driver's force exerted to apply braking to the vehicle. Target braking forces required for the respective road wheels are calculated in a manner to achieve the target vehicle deceleration based on loads to be shared by the respective road wheels. Target brake torque for the respective road wheels are calculated based on the calculated target braking forces. Drive torque for the respective road wheels are calculated. The drive torque calculated for the respective traction road wheels are used to correct the corresponding target brake torque calculated for the respective traction road wheels so as to calculate target traction road wheel brake torque. The braking forces applied to the respective road wheels are controlled in a manner to achieve the target brake torque calculated for the respective follower road wheels and also to achieve the target traction road wheel brake torque calculated for the respective traction road wheels.
