Circuit Description
The Vehicle Stability Enhancement System (VSES) uses inputs from the steering wheel position sensor (SWPS) and the yaw/lateral acceleration sensor to determine if the vehicles steering is centered. The steering centered self calibration occurs when the vehicle travels in a straight path for greater than 10 seconds.
Variation of the SWPS alignment in the steering column is calibrated out by recording a bias value. The bias value is calculated by using inputs from the SWPS and the Yaw/Lateral acceleration sensor.
