The invention provides a method for detecting an abnormal state of an automobile chassis. The method comprises the following steps: acquiring a wheel speed at a current moment and a wheel speed at a historical moment; obtaining an accumulated motion constraint error according to the wheel speed at the current moment and the wheel speed at the historical moment; judging whether the automobile chassis is in an abnormal state or not according to the accumulated motion constraint error; or based on the motion state of the automobile chassis at the historical moment and according to the wheel speed at the current moment, the motion position of the automobile at the current moment is predicted and obtained; and judging whether the automobile chassis is in an abnormal state or not according to the movement position. The technical problem that when an existing sensor for measuring the wheel speed detects whether the automobile chassis is in the abnormal state or not, false detection is prone to occurring is solved, and the technical effects that whether the automobile chassis is in the abnormal state or not is accurately detected, and the false detection rate is reduced are achieved.
本发明提供了一种汽车底盘异常状态的检测方法,包括以下步骤:获得当前时刻的轮速与历史时刻的轮速;根据当前时刻的轮速与历史时刻的轮速,获得累计运动约束误差;根据累计运动约束误差,判断汽车底盘是否处于异常状态;或基于历史时刻的汽车底盘的运动状态,并根据当前时刻的轮速,预测并获得当前时刻的汽车的运动位置;根据运动位置,判断汽车底盘是否处于异常状态。本发明解决了现有测量轮速的传感器在检测汽车底盘是否为异常状态时,容易误检的技术问题,实现了准确检测汽车底盘是否为异常状态,降低误检率的技术效果。
