System Description

INFOID:0000000004212614

1. The system detects the degree of brake pedal operation with a brake stroke sensor and two master cylin-

der pressure sensors, and calculates the optimum hydraulic brake force. The hydraulic pressure source is

adjusted based on this so that the optimum hydraulic control is independently performed on all four

wheels.

2. Meanwhile, the Electronically Controlled Brake system performs control of the normal brakes, ABS, TCS,

VDC in accordance with the operations of the driver.

3. There is a hydraulic backup mechanism that applies master cylinder pressure generated by human power

to the wheel cylinder when the brake control stops, In addition, as a fail safe mechanism, when the brake

control is malfunctioning, the system excludes the malfunctioning sections and continues to perform brake

control on the normal sections. A power backup unit (brake control power supply) is also used to ensure a

stable supply of power to the system.
