Vehicle Stability Enhancement System

Vehicle Stability Enhancement System (VSES) includes an additional level of vehicle control to EBCM. VSES is activated by EBCM, calculating desired yaw rate and comparing it to actual yaw rate input. Desired yaw rate is calculated from measured steering wheel position, vehicle speed and lateral acceleration. The difference between desired yaw rate and actual yaw rate is yaw rate error, which is a measurement of oversteer or understeer. If yaw rate error becomes too large, EBCM will attempt to correct vehicle's yaw motion by applying differential braking to left or right front wheel.
