The invention relates to a control device for a four-wheel steering vehicle. A control device for a four-wheel steering vehicle includes a steering wheel, a front-wheel steering device, and a rear-wheel steering device, and operates the front-wheel steering device and the rear-wheel steering device to continuously perform a first steering in which the steering wheel is operated in a predetermined direction and a second steering in which the steering wheel is operated in a direction opposite to the first steering. When the front wheel is steered in the direction opposite to the steering direction of the front wheel, the absolute value of the steering angular velocity of the front wheel that is steered in accordance with the first steering is higher than a first threshold value, and the absolute value of the steering angular velocity of the front wheel that is steered in accordance with the second steering is higher than a second threshold value. The steering of the rear wheel corresponding to the second steering is restricted.
本发明涉及四轮转向车辆的控制装置。所述四轮转向车辆具备方向盘、前轮转向装置以及后轮转向装置,四轮转向车辆的控制装置使前轮转向装置和后轮转向装置工作,在连续地进行向规定的方向操作方向盘的第一转向和向与第一转向相反的方向操作该方向盘的第二转向,并使后轮向与前轮的转舵方向相反的方向转舵时,在与第一转向对应地转舵的前轮的转舵角速度的绝对值高于第一阈值并且与第二转向对应地转舵的前轮的转舵角速度的绝对值高于第二阈值的情况下,限制与第二转向对应的后轮的转舵。
