A rear-wheel steering control apparatus includes a controller, which performs a first-order lag process. This process is equivalent to a first-order lag transfer function and is represented by a time constant matching loadage data from a rear-wheel stroke sensor and a proportional constant matching vehicle speed data from a vehicle speed sensor. The first-order lag process is performed on a front-wheel steering angle, obtained based on steering-wheel angle data from a steering-wheel angle sensor, to thereby set a target rear-wheel steering angle. Steering of rear wheels to the set rear-wheel steering angle is carried out with a degree of first-order response delay corresponding to the loadage. Thereby, traveling stability and forepart turning performance of a vehicle are improved in various loading and steering conditions. |
