A turning assistance device for a vehicle is configured to execute: a process for acquiring a predicted collision time when the vehicle approaches an obstacle; and a turning assistance process for assisting the turning of the vehicle when the steering operation of the steering wheel is performed in a condition in which the predicted collision time is equal to or less than the predicted determination time. The turning assistance process includes: an in-phase process in which a command to steer the rear wheels in the same direction as the steering direction of the front wheels is output to the rear wheel steering device; and a steering assistance process in which the steering assistance process is executed if the difference between the actual value of the lateral acceleration of the vehicle and the lateral acceleration target value is greater than the difference determination value during execution of the in-phase process. And an inverting process for outputting a command to steer the rear wheel in the direction opposite to the steering direction of the front wheel to the rear wheel steering device.

    本发明提供的车辆的转弯支援装置构成为执行:在车辆接近障碍物的情况下获取碰撞预测时间的处理;以及在碰撞预测时间在判定预测时间以下的状况下进行方向盘的转向操纵操作的情况下,辅助车辆的转弯的转弯支援处理。转弯支援处理包含向后轮用转向装置输出使后轮向与前轮的转向方向相同的方向转向的指令的同相处理、和若在同相处理的执行中车辆的横向加速度的实值与横向加速度目标值的差量比差量判定值大,则向后轮用转向装置输出使后轮向与前轮的转向方向相反的方向转向的指令的反相处理。
