Embodiment Construction

[0095] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0096] The current safety protection system of electric vehicles only considers how to reduce the safety risk after a collision, but does not take into account how to restore the power supply system after a collision accident, especially in environments with high driving risks, such as collisions at traffic intersections, and The collision intensity of the electric vehicle is low, if the power supply cannot be restored in time at this time, it is very likely to cause a secondary collision. Based on this, the present invention provides a vehicle safety control method for how to cut off the high-voltage power supply system after a vehicle collis...

Abstract

The invention relates to the technical field of vehicle control, particularly provides a vehicle safety control method and device and an electric vehicle and is intended to solve the technical problemof how to cut off and restore a power supply system after an electric vehicle encounters a collision accident. To this end, the vehicle safety control method may execute different high-voltage powersupply system cut-off strategies according to collision strength levels, to be specific: in the case of a high collision strength level, the high-voltage power supply system is quickly cut off in irreversible manner so as to effectively avoid the risk of the high-voltage power supply system; in the case of a low collision strength level, the high-voltage power supply system is cut off in reversible manner so that a vehicle may quickly leave an accident site at the premise that the collision strength is friendly to continued safety driving of the vehicle, and the risk of secondary accidents isdecreased. The vehicle safety control device and the electric vehicle may execute and implement the steps of the vehicle safety control method.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle safety control method and device and an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle that can be powered by a battery. The electrical system of an electric vehicle includes a low-voltage electrical system and a high-voltage electrical system. Among them, the high-voltage electrical system mainly includes high-voltage power supply system, high-voltage motor and electric drive control system and other equipment. The working voltage of the high-voltage power supply system is as high as several hundred volts, which is far higher than the safe voltage, and when the high-voltage power supply system leaks electricity, such as the power battery leakage caused by a vehicle collision, it will directly affect the personal life and property safety of drivers and passengers. harm. [0003] At present, the method of vehicle acciden...
