Abstract:
A brake system of a vehicle having front left, front right, rear left and rear right wheels, the brake system comprising wheel cylinders each corresponding to each of the above-mentioned wheels, a brake pedal adapted to be depressed by a driver, a master cylinder operatively connected with the brake pedal to be compressed according to a depression thereof by the driver, powered fluid pressure source means for generating a powered fluid pressure, fluid flow control circuit means including control valves, and an automatic controller for selectively operating the powered fluid pressure source means and the control valves so as to supply a selected one or more of the wheel cylinders with a fluid pressure controlled from the powered fluid pressure of an execution of the turning behavior control of the vehicle according to running conditions of the vehicle, while isolating the one or more of the wheel cylinders selected for the behavior control from the master cylinder wherein the automatic controller also executes a deceleration brake control of supplying at least one of the wheel cylinders not selected for the behavior control with a fluid pressure controlled from the powered fluid according to a braking calculation based upon a depression of the brake pedal by the driver during the execution of the behavior control, the at least one wheel cylinder being isolated in the meantime from the master cylinder.
