Patent ID: 7178883

Claim:
A vehicular brake system comprising a brake actuator that enables brake assist to be carried out, the brake assist increasing a braking force exhibited by wheel brakes in response to a braking operation input by a vehicle driver in comparison with the braking force when it is unassisted, wherein the vehicular brake system further comprises: braking operation detection cans for detecting a braking operation by the vehicle driver; emergency avoidance steering operation detection means for detecting an emergency avoidance steering operation by the vehicle driver; actuator control means for controlling operation of the brake actuator so as to carry out the brake assist in response to the braking operation detection means detecting a braking operation while the emergency avoidance steering operation is being detected by the emergency avoidance steering operation detection means or during a period from the detection of an emergency avoidance steering operation by the emergency avoidance steering operation detection means to the time when a predetermined period of time has elapsed after the detection has ended; turning movement target value determination means for determining a target value for vehicle turning movement; turning movement actual value detection means for detecting an actual value of vehicle turning movement; and turning movement control means for comparing the actual value with the target value and controlling the braking forces of the wheel brakes based on the result of the comparison so that the actual value approaches the target value; and brake assist disabling means for disabling brake assist by the brake actuator when control by the turning movement control means is being carried out before the vehicle driver carries out a braking operation.
