Antilock Brakes / Traction Control Systems: Description and Operation

Description of functions

1. Anti-lock brake system (ABS)
(1) Helps prevent wheel lock when the brakes are applied quickly or on a slippery road surface.
2. Electronic brake distribution control (EBD)
(1) The EBD control uses the ABS to control distribution of brake force to front and rear wheels depending on driving conditions. Also, the system controls application of braking force to right and left wheels to stabilize vehicle motion while cornering.
3. Brake assist (BA)
(1) The main purpose of brake assist is to provide additional braking force for a driver who cannot depress the brake pedal hard when hard braking is needed. With this assist, braking performance of the vehicle is assured.
4. Traction control (TRC)
(1) Controls slipping of driving wheels when the driver depress the accelerator pedal too far to starts or accelerates the vehicle on a slippery surface.
5. Vehicle stability control (VSC)
(1) Controls vehicle skidding sideways when vehicle is apt to understeer or oversteer excessively while cornering.
