The invention particularly relates to a rapid detection and correction method for deviation of an automobile steering wheel. The method comprises the following steps: calculating E1 and E2 based on an obtained vehicle driving data stream; calculating T1 and T2 based on the obtained vehicle chassis related data; based on the T1, the T2, the E1 and the E2, whether the driving direction and the position of the steering wheel deviate or not is judged through a first preset condition; when the driving direction and the position of the steering wheel deviate, obtaining preset T1 and T2 through a second preset condition based on T1, T2, E1 and E2; calculating T0 through a first preset algorithm based on preset T1 and T2; t is acquired, and T01 and T0r are calculated through a second preset algorithm based on T and T0; and performing direction deviation correction on the current vehicle based on the T01 and the T0r. According to the method, the vehicle direction deviation under the influence of the current working condition is reflected by acquiring the related data of the vehicle chassis, so that the detection and correction of the vehicle direction deviation are simply and efficiently realized on the basis of the vehicle chassis level under the condition of not changing the original driving characteristics.

    本发明具体涉及一种汽车方向盘偏差的快速检测与校正方法;所述方法包括:基于获取的车辆行驶数据流计算E1及E2;基于获取的车辆底盘相关数据计算Tl及T2;基于Tl、T2、E1与E2,通过第一预设条件判定行驶方向及方向盘位置是否出现偏差;当行驶方向及方向盘位置出现偏差时,基于Tl、T2、E1与E2,通过第二预设条件获取预设的Tl及T2;基于预设的Tl及T2,通过第一预设算法计算获得T0;获取T,基于T及T0通过第二预设算法计算获得T0l及T0r;基于T0l及T0r对当前车辆进行方向偏差校正。本发明通过获取车辆底盘相关数据,以反射当前工况影响下的车辆方向偏差,从而在不改变原有驾驶特性的情况下,基于车辆底盘层面,简单高效地实现车辆方向偏差检测及校正。
