Vehicle front road surface accumulated water depth detection system based on vehicle sensor

Abstract

The invention provides a vehicle front road surface accumulated water depth detection system based on a vehicle sensor, and relates to the technical field of vehicle driving safety. The vehicle front road surface accumulated water depth detection system based on the vehicle sensor comprises a vehicle and a processing unit. The vehicle comprises a sensor assembly, and the underwater depth and the water surface height at the position with the preset distance in front of the vehicle can be obtained through the sensor assembly. The system for detecting the depth of accumulated water on the road surface in front of the vehicle based on the self-vehicle sensor can meet the technical requirements of detecting the depth of accumulated water on an irregular road surface profile in front of the vehicle based on a sensor assembly carried by the vehicle; and the vehicle can detect the depth of the accumulated water on the irregular road surface contour in real time, and the driving safety is ensured under the condition of the accumulated water on the road. Meanwhile, compared with an existing method for detecting the depth of accumulated water on the irregular road surface contour, the method has the advantages of being low in cost, compact in structure and low in power consumption, a long preview distance can be achieved, and the measurement precision can be guaranteed.

Description

technical field [0001] The invention relates to a detection system, in particular to a vehicle front road area water depth detection system based on a self-vehicle sensor, which belongs to the technical field of vehicle driving safety. Background technique [0002] There are two main causes of water accumulation on urban roads: one is the rainwater accumulated after rainfall in the lower-lying areas of the road surface; the other is the flood disaster caused by poor drainage and heavy rainfall. If a human driver miscalculates the depth of the accumulated water and directly drives through the water, it will easily cause engine flameout, water intake and exhaust pipes, or electric leakage of high-voltage components of the vehicle, which will seriously threaten the safety of the driver's personal and property. [0003] At present, there are mainly the following technical solutions in the field of road traffic bathymetry: ① method based on preset road surface contour shape; ② me...
