Method and system for controlling working conditions of a complete vehicle, and vehicle

Abstract

The invention provides a whole vehicle working condition control method, system and an automobile, and relates to the technical field of automobiles. The whole vehicle working condition control method includes the steps that the automobile in a dormant state is controlled to enter a low voltage power-on state according to a received wake-up instruction; when the automobile enters the low voltage power-on state, the automobile is controlled to be subjected to high voltage power-on when the automobile has a high voltage power-on demand at present is judged; after high voltage power-on of the automobile is completed and the automobile enters a high voltage power-on completion state, a present working condition of the automobile is obtained; and the working condition under high voltage power-on of the automobile is controlled to switch into a target working condition according to a preset working condition priority and the present working condition. According to the scheme of the whole vehicle working condition control method, system and the automobile, the problems that high voltage power-off needs to be conducted firstly and then power-on is conducted in order to achieve switching between the whole vehicle working conditions of an existing electric automobile, and the operation real-time performance of the automobile is poor, and a relay of a high voltage system is shortened in life due to the fact that the working conditions are switched after power-on is completed are solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for controlling working conditions of a complete vehicle and an automobile. Background technique [0002] With the improvement of the economic level, people buy more and more cars, and the number of cars has increased significantly in recent years. However, the increase of fuel vehicles has not only caused a great consumption of energy, but also caused great harm to the environment due to the exhaust gas produced. Therefore, electric vehicles using electric energy as power have gradually entered the market and are widely favored. [0003] However, switching between the working conditions of the existing electric vehicle requires that the high-voltage power be turned off and then turned on again, and the working conditions should be switched after the power-on is completed, resulting in poor real-time operation of the vehicle and shortened life of the high...

Problems solved by technology

[0003] However, the switching between the working conditions of the existing electric vehicle requires that the high-voltage power be turned off and then turned on again, and the working conditions should be switched after the power-on is completed, resulting in poor real-time operation of the vehicle and shortened life of the high-voltage system relays.
