4) Operation in Front Wheel Skid Tendency Control
D When front wheel skidding is detected, motive force is limited and braking control is performed based
on the amount of front wheel skid tendency. Accordingly, a moment of force is generated in the vehicle
turning direction to limit front wheel skid tendency. (VSC function)
D In the case of a front wheel skid tendency, the steering torque will be light as a signal to the driver.
D With the VDIM, if the driver turns the steering wheel excessively, the EPS ECU will receive command
signals from the skid control ECU. Based on these signals, the EPS ECU will operate to reduce the
steering assist. This prevents the driver from increasing the front wheel skid tendency.

5) Operation in Rear Wheel Skid Tendency Control
D When rear wheel skidding is detected, motive force is limited and braking control is performed based
on the amount of rear wheel skid tendency. Accordingly, an anti-spin moment is generated to limit the
rear wheel skid tendency. (VSC function)
D With the VDIM, the EPS ECU receives command signals from the skid control ECU. Based on these
signals, the EPS ECU operates the motor for the electric power steering to provide steering assist to
help the driver compensate for the rear wheel skid tendency. This enables the driver to operate the
steering wheel easily.
