Handling Control

Based on signals about driving wheel and driven wheel rotational speeds, TCS control unit calculates vehicle's "yaw" rate (i.e., the turn rate of vehicle's body). Based on signals from steering angle sensor, TCS control unit also calculates yaw rate expected by driver. If difference between actual and expected yaw rates is substantial (if the direction of the car's body will exceed the driver's expected line) TCS control unit signals the throttle actuator, which closes the throttle valve, thus reducing engine power and maintaining the expected line.
