Example Embodiment

[0042] The present invention will be further described below in conjunction with the drawings.

[0043] The electric vehicle power-off method of the present invention includes the following steps:

[0044] (1) When the power supply of the whole vehicle is in Ready gear, the steps to power off the whole vehicle are as follows:

[0045] Such as figure 2 As shown, (1) Real-time acquisition of car door status information, when the body controller 3 detects that the main driver or assistant driver door status changes from door open to door closed, and all doors are closed, the body controller 3 drives the low-frequency antenna 4 Detect the smart key 5. If the smart key is not detected in the car, and the driver and co-driver unmanned signal from the seat sensor 2 are received, and the current vehicle speed is less than the preset speed (for example: 3km / h), the body The controller 3 issues a power-off request command. After receiving this signal, the VCU 8 disconnects the ON high-voltag...

Abstract

The invention discloses an electric vehicle power-off method and system, a computer readable storage medium and an electric vehicle. The electric vehicle power-off method comprises the steps that: a power source is in a Ready gear: (1) a main driver/co-driver is changed from an opened state to a closed state, and all vehicle doors are in a closed state: whether power-off is needed is judged according to a key signal, whether people exist in the main driver seat and the co-driver seat or not and a vehicle speed signal; (2) power-off request: whether to power off or not is judged according to the vehicle speed signal; the power source is in an ON high-voltage gear: (1) the main driver/co-driver is changed from an opened state to a closed state, and all doors are in a closed state: whether topower off is judged according to a key signal and whether the main driver seat and the co-driver seat are occupied by people; (2) power-off request: power-off operation is performed based on the power-off request signal; the power source is in an ON low-voltage gear: (1) when the main driver/co-driver is changed from an opened state to a closed state and all doors are in a closed state: whether to power off is judged according to a key signal and whether the main driver seat and the co-driver seat have people or not; and (2) power-off request: power-off operation is performed based on the power-off request signal. Power-off of the power supply of a whole vehicle can be automatically completed.

Description

technical field [0001] The invention belongs to the technical field of power supplies for new energy vehicles (hybrid vehicles or pure electric vehicles), and in particular relates to a method and system for powering off an electric vehicle, a computer-readable storage medium and an electric vehicle. Background technique [0002] Automobile intelligence and humanization are the trend of automobile development. At present, the keyless entry and start system has almost become the standard configuration of automobiles, but most of the car's keyless start functions need to be realized by manually pressing the start-stop switch, which is not humanized and intelligent enough. . [0003] Therefore, it is of great significance to develop a system that cancels the start-stop switch and can perform the power-off operation of the whole vehicle by detecting the driver's subjective intention and virtual buttons. Contents of the invention [0004] The object of the present invention is...
