Whole vehicle control method and device for pure electric vehicle

The invention discloses a whole vehicle control method and device for pure electric vehicle, belongs to the technical field of pure electric vehicle, and solves the technical problem that a traditional whole vehicle control method and controller cannot determine and deal with the self faults, and the safety and reliability are low. The whole vehicle control method for a pure electric vehicle comprises the steps that a first control unit and a second control unit acquire vehicle internal part information respectively, and based on the vehicle internal part information, implement data processing to generate control information which is used for controlling the vehicle; the data synchronization is made between the first control unit and the second control unit, the first control unit and the second control unit check if the working states of each other are normal based on the synchronized data; when the first control unit works normally, the first control unit outputs control information, and when the first cont
