Power supply control method and system of central control system of electric vehicle

Abstract

The invention discloses a power supply control method and system of a central control system of an electric vehicle. The method comprises the steps that according to working states of the central control system of the electric vehicle under different application scenes, multiple power supply mode states are set correspondingly; voltage values of a storage battery of the electric vehicle and operation events of the electric vehicle are detected, and according to preset state switching conditions and priority levels, switching among different power supply mode states is achieved; according to the power supply mode states, the central control system is subjected to corresponding power supply control. The power supply control method and system of the central control system of the electric vehicle can achieve power supply optimization control on the central control system, shorten the starting time, achieve power supply optimization, meet the operation experience of users, are high in intelligent degree, and can be widely applied to control systems of electric vehicles.

Description

technical field [0001] The invention relates to the field of electric vehicle power supply control, in particular to a power supply control method and system for a central control system of an electric vehicle. Background technique [0002] Glossary: [0003] Central control system: The central control unit of the car, including the touch display screen, which can perform display and touch control operations at the same time. [0004] With the rapid development of electric vehicles, people have higher and higher requirements for automobile automation and intelligence. In terms of user experience, it is even more necessary for the car to be humanized. The traditional power mode of the large central control screen only has two modes: shutdown and startup.

[0004] With the rapid development of electric vehicles, people have higher and higher requirements for automobile automation and intelligence. In terms of user experience, it is even more necessary for the car to be humanized. The traditional power mode of the large-screen central control only has two modes: shutdown and startup. The status, the startup process is slow when the power is turned on, and the vehicle cannot be controlled through the large central control screen after the power is turned off, such as remote control of the vehicle to turn on the air conditioner or automatic parking by mobile phone

At present, the large central control screen of some electric vehicles can be used to remotely control the mobile phone to find the car and turn on the air conditioner after the vehicle is powered off, which is intelligent, but in general, the large central control screen consumes a lot of power consumption of the vehicle , The power status of the central control large screen on electric vehicles is mainly controlled according to the vehicle status. After the vehicle is powered on, the central control starts, and after the vehicle is powered off, the central control shuts down. The logic is too simple, the startup process is long, and it cannot satisfy the user after shutdown. relevant experience, it is difficult to meet the needs of intelligence
