[0002] At present, when an electric vehicle is wading through water, the driver cannot know the depth of the vehicle's wading in real time, and the high-voltage components of the vehicle may cause short circuits and other dangers due to water ingress.
If the electric vehicle continues to drive, it may lead to wading too deep, causing the vehicle to fall into the water. Since the

Abstract

The invention discloses a vehicle wading early-warning method and system and a vehicle falling-into-water early-warning method and system. The wading early-warning method comprises the steps of obtaining vehicle wading depth and vehicle speed, judging if the wading depth reaches a set threshold and judging if the vehicle speed is larger than zero, wherein if the wading depth reaches the set threshold and the vehicle speed is larger than zero, an alarming prompt is given out. The falling-in-water early-warning method comprises the steps of obtaining vehicle wading depth and vehicle speed, judging if the wading depth is larger than zero and judging if the vehicle speed is equal to zero, wherein if the wading depth is larger than zero and the vehicle speed is equal to zero, high-voltage electricity output of a power battery is cut off. By means of the wading early-warning method and system, people in a vehicle can be reminded when the wading depth is too large, and therefore the vehicle can be prevented from being driven into a deep water area mistakenly and high-voltage parts of the vehicle can be prevented short circuit. By means of the falling-into-water early-warning method and system, high-voltage output of the power battery can be cut off automatically when the vehicle falls into water, and therefore passengers can be prevented from being hurt by electric shock and dangers caused by short circuit of high-voltage parts can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a vehicle wading early warning method and system, and a vehicle falling into water early warning method and system. Background technique [0002] At present, when an electric vehicle is wading through water, the driver cannot know the depth of the vehicle's wading in real time, and the high-voltage components of the vehicle may cause short circuits and other dangers due to water ingress. If the electric vehicle continues to drive, it may lead to wading too deep, causing the vehicle to fall into the water. Since the whole vehicle has 320V high-voltage electricity, if it is not cut off in time, the whole vehicle body may have high-voltage electricity, which is harmful to the personnel inside the vehicle. It will cause electric shock injury, which is relatively dangerous; at the same time, the high-voltage components of the vehicle may also burn out due to a short circuit,...
