Road surface water depth detecting method and device and vehicle

Abstract

The invention relates to a road surface water depth detecting method and device and a vehicle. The method comprises the following steps: when the vehicle wades into water, acquiring a distance measurement signal transmitted by a radar mounted on the vehicle, wherein the distance measurement signal comprises distance measurement information for at least one target point on a road surface; acquiringvehicle inclination information and vehicle underwater penetration information; and determining water depth at the position of at least one target point on the road surface according to the distancemeasurement information of at least one target point on the road surface, the vehicle inclination information and the vehicle underwater penetration information. The target point can be an optional expected detection position point, can be a position point located on the road surface in front of the radar, and can also be a position point on a vertical downward road surface of the radar. Therefore, the vehicle not only can acquire current underwater penetration and current road surface water depth, but also can acquire the water depth of the road surface in front of the vehicle, and thus can provide accurate and reliable data support for determination of a follow-up running strategy and risk avoidance.

Description

technical field [0001] The present disclosure relates to the field of vehicles, in particular, to a road surface water depth detection method, device and vehicle. Background technique [0002] With the popularization of vehicles, vehicle safety issues are becoming more and more prominent, and there are more and more safety accidents caused by wading. For example, when the vehicle is driving on a road with too deep water, there will be failures such as engine flameout and battery power failure. serious threat. [0003] In order to ensure the safety of the vehicle when driving through water, some models are now equipped with a liquid level switch to detect the current depth of the vehicle entering the water. The liquid level switch realizes the switching action by floating the buoy on the water surface. Since the floating device of the buoy will shake up and down with the bumps of the vehicle, it is easy to cause false triggering and cause the problem of inaccurate detectio...
