Problems solved by technology

However, after the vehicle enters the water, as time goes by, the vehicle circuit system faces the risk of short circuit. If the vehicle can determine the danger as soon as possible after wading, and automatically open the windows and sunroof in time, the probability of occupant escape can be greatly increased.
[0003] Most of the existing vehicle flood monitoring technologies have additional sensors, such as water level sensors for detecting water levels, tire pressure sensors for detecting tire pressure, etc. However, additional sensors on vehicles increase the cost and layout space
In addition, the principle of instantaneous change of tire pressure after flooding, the scheme of judging whether the vehicle is flooded through the tire pressure sensor, for off-road vehicles with deep wading depth, when driving in the water flow, the tire pressure will also have similar changes, It is difficult to distinguish from flooding, which will lead to poor accuracy and reliability of vehicle flooding monitoring

example 1

[0052] Example 1: The step S2 includes the following steps:

[0053] Step S21, setting a height threshold;

[0054] Step S22: Determine whether the vehicle height exceeds the height threshold;

[0055] Step S23. If yes, it is judged that the vehicle is flooded; otherwise, it is judged that the vehicle is not flooded.

example 2

[0056] Example 2: The step S2 includes the following steps:

[0057] Step S24, setting a signal change rate threshold;

[0058] Step S25: Determine whether the vehicle height change rate exceeds the signal change rate threshold;

[0059] Step S26. If yes, it is judged that the vehicle is flooded; otherwise, it is judged that the vehicle is not flooded.

[0060] Step S3: If the vehicle is flooded, a rescue operation is performed.

[0061] It should be noted that the occurrence of vehicle flooding refers to the fact that the vehicle is in water with a certain wading depth, and the buoyancy generated by the water is sufficient to change the attitude of the vehicle suspension, causing the vehicle to be unable to drive normally and may be harmful to passengers. The lives of different vehicles pose a threat. The corresponding wading depths of different vehicles are different, and the corresponding vehicle height and other parameters are related.

Abstract

The invention relates to a vehicle water logging monitoring rescue method and system, a controller and a medium. The method includes the steps of acquiring a vehicle height sensor signal; determiningwhether the vehicle is flooded according to the vehicle height sensor signal and a preset monitoring threshold; and performing a rescue operation if the vehicle is flooded. According to the invention,vehicle water logging is monitored through the vehicle height sensor signal, and a corresponding rescue measure is taken, thereby raising the accuracy and reliability of vehicle water logging monitoring.

Description

Technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle flooding monitoring and rescue method and system, a controller and a medium. Background technique [0002] In recent years, heavy rains have occurred frequently, and many places have faced flooding disasters. It is not uncommon for vehicles to be flooded. There are frequent incidents of vehicles being flooded and causing casualties. After the vehicle is submerged, it is difficult to open the door to escape due to the different pressures inside and outside the vehicle. Therefore, opening the windows and sunroof is an effective way for the occupants in the vehicle to save themselves. However, after the vehicle enters the water, as time increases, the vehicle circuit system faces the risk of short circuit. If the vehicle can determine the danger as soon as possible after wading, and automatically open the windows and sunroof in time, it can greatly increase the probabili...
