The invention provides a steering wheel returning method and device. The method comprises the steps: obtaining the running speed, collected by a speed sensor in real time, of a vehicle, and determining that the sight line direction of a driver deviates from the front direction of a cockpit of the vehicle; then determining whether the driver has a parking intention or not by judging whether the maintaining time when the running speed of the vehicle is zero exceeds a first time threshold value T1 or not and judging whether the maintaining time when the sight line direction of the driver deviates from the front direction of the cockpit exceeds a second time threshold value T2 or not; and after the driver is determined to have the parking intention, acquiring the deviation angle a, collected by the angle sensor, of the steering wheel, and when the deviation angle a is larger than a set angle threshold value, enabling the steering wheel to return. According to the technical scheme, the parking intention judgment accuracy of the driver can be improved, and therefore the steering wheel returning accuracy of the vehicle is improved too.

    本申请提供一种方向盘的回正方法及回正装置,本申请提供的技术方案中,获取速度传感器实时采集的车辆的运行速度和确定驾驶员的视线方向偏离车辆的驾驶座舱的前方方向后,通过判断车辆的运行速度为零的维持时间是否超过第一时间阈值T1,以及判断驾驶员的视线方向偏离驾驶座舱的前方方向的维持时间是否超过第二时间阈值T2来确定驾驶员是否有停车意图;在确定驾驶员有停车意图后,获取角度传感器采集的方向盘的偏移角度a,当偏移角度a大于设定的角度阈值时,控制方向盘回正。本申请的技术方案可以提高驾驶员的停车意图判断准确性,从而提高车辆的方向盘回正的准确性。
