Abstract
A steering system for a vehicle includes: a front wheel steering device configured to steer a front wheel, a rear wheel steering device configured to steer a rear wheel, and a controller configured to control the front wheel steering device and the rear wheel steering device such that the front wheel and the rear wheel are steerable independently of each other. When the front wheel passes unevenness, the controller executes a rear wheel avoidance control to avoid the rear wheel from passing the unevenness. In the rear wheel avoidance control, the controller determines a rear-wheel avoidance side slip angle, which is a vehicle center-of-gravity point side slip angle to be realized, and determines a target steering angle, which is a steering angle to which each of the front wheel and the rear wheel is to be steered, based on the rear-wheel avoidance side slip angle.
