BRAKE CONTROL SYSTEM


  1. OUTLINE


    1. The following brake control functions are provided: Anti-lock Brake System (ABS), Electronic Brake force Distribution (EBD), brake assist, Traction Control (TRC), Vehicle Stability Control (VSC), hill-start assist control, brake hold, steering cooperative control and automatic transmission cooperative control.

    2. Vehicle Dynamics Integrated Management (VDIM) is used.

    3. An electronically controlled brake system is used to control the hydraulic pressure at the 4 wheels.

  2. MAIN FEATURES


    1. Vehicle Dynamics Integrated Management (VDIM)


      1. In contrast to the ABS, TRC and VSC functions that were controlled individually in the conventional brake control system, the VDIM manages these functions in the form of an integrated system.

      2. Furthermore, the VDIM effects cooperative control together with the Electric Power Steering (EPS) system and Variable Gear Ratio Steering (VGRS)* in order to improve the dynamic performance of the vehicle to "run, turn, and stop".

    2. Electronically Controlled Brake System


      1. In this system, the conventional brake booster portion has been discontinued. Instead, it consists of a power source and hydraulic control portions.

      2. During normal braking, the fluid pressure generated by the master cylinder does not directly actuate the wheel cylinders, but serves as a hydraulic pressure signal. Instead, the actual control pressure is obtained by regulating the fluid pressure of the hydraulic power source in the brake actuator assembly, which actuates the wheel cylinders.

      3. The brake control power supply assembly is used as an auxiliary power source, to supply power to the brake system in a stable manner.
