Vehicle control method, system and vehicle

Abstract

The invention provides a control method and system of a vehicle and the vehicle. The vehicle comprises a wading detecting device for identifying a water surface and detecting the wading depth. The control method of the vehicle comprises the steps that a wading mode request signal is received; whether the vehicle satisfies the conditions for entering into the wading mode or not is judged, and the conditions for entering into the wading mode include that the wading detecting device identifies the water surface and the current vehicle speed of the vehicle is less than a preset vehicle speed; andif it is determined that the vehicle meets the conditions for entering into the wading mode, the vehicle is controlled to enter into the wading mode to execute a preset wading control strategy and shows the wading depth. The control method of the vehicle can improve the passing ability, stability and safety of the vehicle during wading.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] In the process of actually driving a vehicle, the following working conditions are often encountered: city streets after heavy rain, outdoor small rivers or large ditches, etc. In these cases, the wading of the vehicle is involved. The impact of the wading road on the driving state of the vehicle is completely different from that of other terrains on the vehicle state. 2. The braking performance of the braking system will be reduced in a short time after the vehicle is wading; 3. If the engine intake pipe enters the water or the engine exhaust pipe sucks back during the wading process Water ingress can cause irreversible damage to the engine. Therefore, when the vehicle is wading through water, the passability and safety cannot be guaranteed, and currently there is no relevant technology that propos...

AI Technical Summary

Problems solved by technology

In these cases, the wading of the vehicle is involved. The impact of the wading road on the driving state of the vehicle is completely different from that of other terrains on the vehicle state. 2. The braking performance of the braking system will be reduced in a short time after the vehicle is wading; 3. If the engine intake pipe enters the water or the engine exhaust pipe sucks back during the wading process Water ingress can cause irreversible damage to the engine

Therefore, when the vehicle is wading through water, the passability and safety cannot be guaranteed, and currently there is no relevant technology that proposes a corresponding control strategy for vehicle wading to protect the vehicle accordingly
