Vehicle water level detection device, method and vehicle

Abstract

The invention relates to a vehicle water level detecting device and method and a vehicle. The vehicle water level detecting device comprises a shell, a pressure sensor and a control circuit; the inside of the shell is hollow, and the shell is divided into a first chamber of a pressure inlet and a second chamber for sealing stipulated air pressure; the pressure sensor is used for acquiring a pressure different value of the first chamber and the second chamber; the control circuit is used for determining the water level depth according to the pressure difference value. The vehicle water level detecting device and method can be not limited by using environment conditions or using conditions, can continuously and precisely detect the depth for the vehicle to enter water and is applicable to detecting the depth for the vehicle to be soaked into the water.

Description

technical field [0001] The present disclosure relates to the field of vehicle safety, in particular, to a vehicle water level detection device, method and vehicle. Background technique [0002] Nowadays, water level detection sensors have a wide range of applications. At present, the main technologies used are: capacitive sensing water level sensors, magnetic switch water level detection devices and ultrasonic water level detection sensors, which are used in reservoirs, water towers, boilers and other aspects. However, the capacitive sensing water level sensor needs to be placed vertically, which has higher requirements on the installation environment. The magnetic switch water level detection device cannot continuously detect the depth of the water level, and it cannot be subject to large vibrations, which will result in the inability to accurately detect the water level. The ultrasonic water level detection sensor cannot find a suitable reflection point in the water, so i...

AI Technical Summary

Problems solved by technology

However, the capacitive sensing water level sensor needs to be placed vertically, which has higher requirements for the installation environment

The magnetic switch water level detection device cannot continuously detect the depth of the water level, and it cannot be subject to large vibrations, which will result in the inability to accurately detect the water level

The ultrasonic water level detection sensor cannot find a suitable reflection point in the water, so it cannot effectively detect

[0003] Therefore, several existing water level sensors are not suitable for the depth of vehicle immersion in water due to the limitation of environmental conditions or use conditions.
