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

Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 is a flowchart of a vehicle control method according to an embodiment of the present invention.

[0035] Specifically, the vehicle involved in the embodiment of the present invention includes, for example, a wading detection device, which is used to identify the water surface and detect the wading depth of the vehicle. In a specific embodiment, the wading detection device is composed of, for example, a monocular camera and a radar, and its installation position is below the rearview mirror, so as to protect the camera and radar.

[0036] Based on this, combine figure 1 As shown, the vehicle control method according to one embodiment of the present invention includes th...

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...
