Problems solved by technology

[0003] This system for detecting the depth of water when the vehicle is wading has the following disadvantages: although it can detect the wading situation of the vehicle, it needs to follow the position of the rearview mirror along the water surface height in the vertical direction of the vehicle body, the posture of the vehicle body and the height of the chassis (i.e. the height of the rearview mirror). The position along the vertica

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 It is a flowchart of a vehicle wading detection method according to an embodiment of the present invention.

[0035] Such as figure 1 As shown, the vehicle wading detection method according to one embodiment of the present invention includes the following steps:

[0036] S101: Detecting the attitude of the vehicle body.

[0037] Wherein, the attitude of the vehicle body may be data such as roll and / or pitch of the vehicle (such as roll angle and pitch angle of the vehicle body). Here, roll refers to the angle of rotation about the longitudinal axis of the vehicle, and pitch refers to the angle of rotation about the transverse axis of the vehicle. It should be noted th

Abstract

The invention provides a vehicle water-wading detection method and system and a vehicle. A vehicle water-wading detection method includes detecting a posture of a vehicle body; detecting the referencewater level between the body reference position and the water surface; obtaining the highest water level of the water surface relative to the vehicle body- according to the posture of the vehicle body and the reference water level, wherein the highest water level refers to the distance from the highest position of the water surface relative to the vehicle body to the reference position of the vehicle body in the vertical direction of the vehicle body. The method of the invention can simply and conveniently determine whether a vehicle can safely and reliably pass through a puddle and the like,thereby ensuring driving safety. In addition, the system is not affected by the change of vehicle chassis height when the vehicle is unloaded or loaded. No matter how the vehicle chassis height changes, the system can accurately detect the vehicle wading, and has the advantages of accurate and reliable detection of the vehicle wading.
