The invention relates to the technical field of steering systems, in particular to a method for judging straight running of a vehicle by using a wheel speed or a yaw angle. A method for judging straight running of a vehicle through the wheel speed or the yaw angle specifically comprises the following steps that S1, current vehicle state signals are obtained, and the vehicle state signals comprise the vehicle speed, the four-wheel speed, the yaw angle speed, the lateral acceleration, the steering wheel rotating speed and the hand power of a driver; and S2, carrying out validity judgment on the vehicle state signal obtained in the step S1. Compared with the prior art, the method for judging straight running of the vehicle through the wheel speed or the yaw angle is provided, whether the vehicle is in the straight running state or not is judged through the four wheel speeds, the vehicle yaw angle speed and the lateral acceleration, the method can be suitable for different vehicle model configurations, and the judgment precision and stability are improved.
本发明涉及转向系统技术领域,具体地说是一种利用轮速或横摆角判断车辆直行的方法。一种利用轮速或横摆角判断车辆直行的方法,具体方法如下:S1,获取当前的车辆状态信号,所述的车辆状态信号包括车速、四轮轮速、横摆角速度、侧向加速度、方向盘转速、驾驶员手力;S2,对步骤S1获取的车辆状态信号进行有效性判断。同现有技术相比,提供一种利用轮速或横摆角判断车辆直行的方法,通过四个轮速和车辆横摆角速度,侧向加速度来判断车辆是否处于直线行驶状态的方法,可以适用于不同的车型配置上,提高判断精度和稳定性。
