The invention provides a vehicle fording depth detection method, which comprises the following steps of: acquiring the actual fording depth of a vehicle fording reference point according to inertial data of a vehicle and vehicle configuration parameters, and acquiring the active driving intention of a driver according to the depth of an accelerator pedal and the main cylinder pressure of a brake pedal in the process of acquiring the actual fording depth; when the vehicle corresponding to the driving intention is suddenly accelerated or braked, the numerical value of the actual fording depth is locked, and the situation that the wrong actual fording depth is output is avoided; and the vehicle inertia state is judged to be a stable state according to the driving intention, and updating of the actual fording depth is recovered. According to the vehicle fording depth detection method, the actual fording depth can be maintained at a numerical value before active rapid acceleration or rapid braking when inertial data abrupt change is caused by active rapid acceleration or rapid braking of the vehicle, the situation that the obtained actual fording depth data is abnormal and driving is wrongly guided due to the abrupt change of the inertial data is avoided, and the vehicle fording depth detection accuracy is improved. The vehicle wading driving assisting effect can be improved, and the user experience is improved.

    本发明提供了一种车辆涉水深度检测方法,其根据车辆的惯性数据结合车辆配置参数获得车辆涉水参考点的实际涉水深度,在获取实际涉水深度中,还根据油门踏板深度和刹车踏板的主缸压力获取驾驶员的主动驾驶意图;在驾驶意图对应车辆会出现急加速或急刹车情况时,锁定实际涉水深度的数值,避免输出错误的实际涉水深度;在根据驾驶意图判断车辆惯性状态为稳定状态,恢复实际涉水深度的更新。本发明的车辆涉水深度检测方法可在车辆主动急加速或急刹车导致惯性数据突变时,将实际涉水深度维持在主动急加速或急刹车之前的数值,避免出现因惯性数据突变导致获得的实际涉水深度数据异常,错误引导驾驶的情况,可提升车辆涉水驾驶辅助效果,提升用户体验。
