Abstract

In a vehicular control system in which target braking torques are set for each of the driven wheels, the smaller target braking torque for the driven wheels is determined. Based on this smaller target braking torque, a target engine torque is calculated, and the engine torque is varied to conform to the target engine torque. Residual braking torques are calculated as differences from the target braking torques for each driven wheel and the target engine torque. These residual braking torques are realized by varying the brake pressure. Therefore the target braking torque is split into an engine torque which is equal for both driven wheels and into a braking torque which may be different for each driven wheel.
