Active detection system and detection method for water inflow of vehicle

Abstract

The active detection system comprises a vehicle window controller and a vehicle control unit, and further comprises a water sensor arranged on a vehicle, the arrangement position of the water sensor on the vehicle is lower than that of the vehicle window controller so as to sense external water inflow earlier, and the vehicle window controller is connected with the vehicle control unit. The water sensor is electrically connected with the vehicle window controller so as to transmit detected water inlet information to the vehicle window controller; the vehicle window controller and the vehicle control unit are in two-way connection so as to send water inflow information to the vehicle control unit, the vehicle control unit controls the vehicle window controller to close a vehicle window after receiving the water inflow information, immediately cuts off control of the vehicle window controller to the vehicle window after the vehicle window is closed, and meanwhile sends vehicle water inflow information to a designated receiving terminal. According to the invention, active detection of water entering the vehicle can be realized, and the vehicle window can be prevented from automatically descending under the condition that the vehicle window controller fails.

Description

technical field [0001] The invention relates to the detection and improvement of preventive measures for vehicle water ingress, in particular to an active detection system and detection method for vehicle water ingress, belonging to the technical field of vehicles. Background technique [0002] At present, the vehicle can judge whether it is raining through the rain sensor on the front windshield in rainy days, and judge whether the status of the window is normal through the controller, and realize the function of automatically closing the window. However, when the window controller is short-circuited and fails due to water ingress, the window may automatically lower the window, and the function of automatically closing the window through the controller cannot be realized. With the development of automobile intelligence, there have been some improvements in the existing technology about smart car windows. [0003] For example, the Chinese invention patent with application n...

Problems solved by technology

[0005] Although the above two patents realize intelligent window closing, they have a single function and cannot avoid the problems caused by the failure of the controller when it encounters water, such as automatic window lowering, and it is also impossible to notify the user of the failure in advance through the cloud
