SYSTEM DESCRIPTION

1. FUNCTION DESCRIPTION

(a) Anti-lock Brake System (ABS)

(1) The ABS helps prevent the wheels from locking when the brakes are applied firmly or when braking on a slippery surface.

(b) Electronic Brake force Distribution (EBD)

(1) EBD control utilizes the ABS and distributes proper brake force between the front and rear wheels in accordance with driving conditions. In addition, when braking while cornering, it also controls the brake forces applied to the right and left wheels, helping to stabilize vehicle behavior.

(c) Brake Assist (BA)

(1) The primary purpose of brake assist is to provide supplementary brake force to assist a driver who cannot generate a large brake force during emergency braking, thus helping ensure the vehicle's braking performance.

(d) Traction Control (TRAC)

(1) Helps prevent slippage of the drive wheels if the driver depresses the accelerator pedal excessively when starting off or accelerating on a slippery surface.

(e) Vehicle Stability Control (VSC)

(1) Helps prevent sideways slippage of the vehicle during strong understeer or strong oversteer while cornering.
