VDC FUNCTION : System Description

INFOID:0000000009752896

• Side slip or tail slip may occur while driving on a slippery road or intending an urgent evasive driving. VDC

function detects side slip status using each sensor when side slip or tail slip is about to occur and improves
vehicle stability by brake control and engine output control during driving.

• In addition to ABS function, EBD function and TCS function, target side slip amount is calculated according

to steering operation amount from steering angle sensor. By comparing this information with vehicle side slip
amount that is calculated from information from yaw rate/side/decel G sensor and wheel sensor, vehicle driv-
