Early warning method and device for vehicle wading

Abstract

The invention provides an early warning method and device for vehicle wading. The method includes: measuring the depth of accumulated water at a preset distance in front of the vehicle according to the measurement results of the laser range finder on the roof, the laser range finder at the bottom of the vehicle, the ultrasonic range finder and the gyro sensor; Whether the depth exceeds the safe depth of the vehicle; if it exceeds, a vehicle warning message will be issued. The present invention also provides a device corresponding to the above method. The technical solution of the present invention, compared with the solution of detecting and warning the depth of accumulated water after wading in the prior art, can detect the depth of accumulated water at a preset distance in front of the vehicle before wading, and detect the depth of accumulated water at a preset distance in front of the vehicle before wading. When the vehicle is at a safe depth, an early warning is issued to improve the efficiency of the vehicle wading early warning, so as to achieve a real vehicle wading early warning.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle safety, in particular to an early warning method and device for vehicle wading. 【Background technique】 [0002] Usually, after the heavy rain, the drainage equipment fails to discharge the accumulated water in time, resulting in a large amount of accumulated water in the concave road section. When a car passes through a concave road section, if the water depth is too deep, the car will stall, causing the car to be trapped in the water, causing certain property losses. What's more serious is that when the car is turned off and the door cannot be opened, it is more likely to cause the driver's life-threatening, so the early warning scheme of the vehicle in terms of wading becomes particularly important. [0003] The existing vehicle wading early warning scheme usually detects and warns after the vehicle is wading. At this time, if the depth of the accumulated water is too deep and the vehicle has...

AI Technical Summary

Problems solved by technology

[0002] Usually, after the heavy rain, the drainage equipment fails to discharge the accumulated water in time, resulting in a large amount of accumulated water in the concave road section

When a car passes through a concave road section, if the water depth is too deep, the car will stall, causing the car to be trapped in the water, resulting in certain property losses

What's more serious is that when the car is turned off and the door cannot be opened, it is more likely to cause the driver's life to be in danger, so the vehicle's early warning scheme for wading becomes particularly important

[0003] The existing vehicle wading early warning scheme usually detects and warns after the vehicle is wading. At this time, if the depth of the accumulated water is too deep and the vehicle has not been warned in time, it may cause the vehicle to stall and be trapped in the water.

Therefore, the existing vehicle wading early warning schemes have poor early warning efficiency and cannot provide real early warning.
