BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

1. FUNCTION DESCRIPTION
(a) Steering Cooperative Control
(1) Enhanced-VSC performs coordinated control consisting of VSC and electronic power steering. By integrating these preventive safety functions, Enhanced-VSC ensures excellent driving stability and maneuverability of the vehicle.
(b) 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.
(c) Electronic Brake force Distribution (EBD)
(1) The EBD control utilizes the ABS, and performs proper brake force distribution between the front and rear wheels in accordance with driving conditions.
When braking while cornering, it also controls the brake forces of the right and left wheels, helping to maintain vehicle behavior.
(d) Brake Assist (BA)
(1) The primary purpose of the brake assist system is to provide auxiliary brake force to assist a driver who cannot generate a large enough brake force during emergency braking, thus helping to maximize the brake performance of the vehicle.
(e) Traction Control (TRAC)
(1) The TRAC system helps prevent the drive wheels from slipping when the driver depresses the accelerator pedal excessively when starting off or accelerating on a slippery surface.
(f) Vehicle Stability Control (VSC)
(1) The VSC system helps prevent the vehicle from slipping sideways as a result of strong front or rear wheel skid during cornering.
(g) Hill-start Assist Control
(1) When the vehicle starts off on a steep or a slippery hill, hill-start assist control detects the backward movement of the vehicle and effects four-wheel hydraulic pressure control to prevents the vehicle from moving backward.
