Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] A vehicle control method suitable for pure electric vehicles, by grading the fault status of the software vehicle, and setting a specific processing method for each level, to control the whole vehicle of pure electric vehicles, specifically including:

[0024] (1) Program the parameters of different fault states in the actual running process of the vehicle in different levels, formulate corresponding vehicle operation modes for different fault states, and program the control commands of different vehicle operation modes, Store the above program in the vehicle controller;

[0025] (2) The vehicle controller collects vehicle status information to judge the current vehicle working status and the driver's driving intention, and judge the current fault state of the vehicle;

[0026] (3) After confirming the fault state, select the corresponding vehicle o...

Abstract

The invention discloses a finished vehicle control method and a finished vehicle control system suitable for a pure electric vehicle. The state of a finished vehicle is subjected to fault grading through software, a special processing mode is set for each grade, and the pure electric vehicle is integrally controlled, so that the finished vehicle can be scientifically and sequentially controlled and managed, and the conservation and control of resources are facilitated; according to hardware, three mutually-independent controller area network (CAN) buses are connected with a motor controller, an energy storage controller and an instrument panel respectively, so that data transmission cannot be influenced mutually; and a transmission speed is increased, so that the control response of the finished vehicle is quick and accurate.

Description

technical field [0001] The invention relates to the vehicle control of pure electric vehicles, in particular to a vehicle control method and system suitable for pure electric vehicles. Background technique [0002] With the rapid development and popularization of automobiles in our country, the issue of energy saving and emission reduction of automobiles has become more and more important. Although the current electronic control technology of internal combustion engines and the application of exhaust purification technologies such as three-way catalysis have reduced the emission and fuel consumption of automobiles to a very low level, it is impossible to fundamentally solve the emission and energy problems of automobiles. Electric vehicles are the best way and way to solve this problem. Major automobile manufacturers and research institutes across the country have invested a lot of human and financial resources in the research and production of new energy vehicles. [0003...
