Abstract

The rear wheel steering system basically operates by external signal, receiving the steering angle and the vehicle speed input. If there is a problem with the external signal of the rear wheel steering, that will be able to change its state. One is immediate stop and the other is stop after move to neutral. In the case of stopping immediately, since it is fixed at a specific rear wheel angle, the front wheel angle must be rotated by the rear wheel angle in order to make a straight advance. However, if the vehicle moves to the neutral position, the driver will feel discomfort because yaw velocity is changed. It is necessary to decide how to set the time to reduce driver discomfort during traveling home. We used the Taguchi methodology of DFSS to derive the appropriate time without the driver's discomfort.
