Control method and system for falling-into-water protection of electric vehicle

Abstract

The invention provides a control method and system for falling-into-water protection of an electric vehicle. The control method for falling-into-water protection of the electric vehicle comprises thesteps that an ECU controller receives pressure data detected by a hydraulic sensor and vehicle body falling-into-water inertia impact force detected by an acceleration sensor; whether the vehicle falls into water or not is judged according to the pressure data and the vehicle body falling-into-water inertia impact force; and when it is judged that the vehicle falls into water, a high-voltage circuit of the vehicle is cut off and all doors and trunks are unlocked. According to the scheme, the ECU controller is used for receiving detection data of the acceleration sensor and the hydraulic sensor, the falling-into-water condition of the vehicle can be judged in time, the high-voltage circuit of the electric vehicle is cut off and the vehicle door is unlocked in time when the vehicle falls into water, the electric shock risk of personnel in the vehicle is avoided, the damage degree of the vehicle is reduced, and the vehicle safety is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method and system for electric vehicle falling into water protection. Background technique [0002] There is high-voltage electricity inside the electric vehicle. When an accidental falling into the water occurs during driving, the occupants of the vehicle will be in danger of high-voltage electric shock, and the electric components of the vehicle will be short-circuited, causing serious damage to the vehicle or irreparable damage. At present, there is no control and treatment method for electric vehicles after falling into the water. The function of lowering the windows of ordinary vehicles cannot avoid the electric shock risk of the occupants after the electric vehicle falls into the water, and reduce the damage of the vehicle. Contents of the invention [0003] Embodiments of the present invention provide a control method and system for protecting an elec...
