1. OVERVIEW

The ESP (Electronic Stability Program) has been developed to help a driver avoid danger of losing

control of the vehicle stability due to understeer or oversteer during cornering. The yaw rate sensor,

lateral sensor and longitudinal sensor in the sensor cluster and the steering wheel angle sensor under

the steering column detect the vehicle conditions when the inner or outer wheels are spinning during

oversteer, understeer or cornering. The ESP ECU controls against oversteer or understeer during

cornering by controlling the vehicle stability using input values from these sensors and applying the

braking force to the corresponding wheels independently. The system also controls the engine power

right before the wheel spin synchronized to decelerate the vehicle automatically in order to maintain the

vehicle stable during cornering.
