Ordinary Control

The torque input to the multi-plate clutch is calculated according to various factors such as intake manifold pressure, torque converter turbine speed and selected speed gear. Based on the calculation result, the basic coupling force of the clutch is determined.

The basic coupling force thus obtained is then corrected according to the road slipperiness (which is determined based on steering angle, yaw rate, lateral G signals from the VDC control module) and the feedback correction factor which is used for making the actual yaw rate agree with the yaw rate estimated from the steering angle sensor signals.
