System Description

ELECTRONICALLY CONTROLLED BRAKE SYSTEM


System Description

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