摘要： PROBLEM TO BE SOLVED: To suppress the abrupt change of a target steered wheel angle when switching a vehicle characteristic mode.
SOLUTION: A target yaw rate and a target lateral velocity are calculated based on the state quantity of a vehicle relating to the travelling state of the vehicle estimated from a vehicle body velocity V and a steering wheel angle θ of a steering wheel 1. The target steered wheel angle of a steered wheel is calculated based on the calculated target yaw rate and target lateral velocity. The steered wheel is steered-wheel-controlled via a steered wheel actuator to the target steered wheel angle as the target value. When a switching to select a vehicle characteristic mode by a driver's operation is detected, temporarily, the target yaw rate and the target lateral velocity are calculated based on the state quantity of the vehicle excluding the state quantity relating to transient characteristics.
