Problems solved by technology

[0004] However, with the continuous increase of the functions of the vehicle controller, the level and logic of the existing code will affect the execution efficiency of the code, so that the performance of the vehicle (for example, the component control code is also called periodically in the working conditions that do not need to run) take up system time) and security is potentially compromised

Embodiment

[0035] like Figure 1~5 As shown, the present invention provides a vehicle control method for new energy electric vehicles, which includes parking mode, ACC mode, power on and off mode, power loss prevention mode, charging mode, and driving mode.

[0036] parking mode

[0037] Since the vehicle controller is in the normal fire power supply state, after the vehicle stops operating, the low-voltage circuit will be disconnected, and all peripheral circuits will stop working at this time until it is woken up next time.

[0038] ACC mode

[0039] The ACC mode is the vehicle running mode with the key in the first gear. In this mode, the low-voltage circuit is connected, the power supply is completed for the low-voltage circuit equipment, and the initialization of control parameters and the initialization of CAN sending and receiving parameters are completed.

[0040] Power on and off mode

[0041] like figure 2 As shown, the power-on and power-off modes are divided into power-o...

Abstract

The invention discloses a new energy electric vehicle control method which comprises a parking mode, an ACC mode, a power on / off mode, a power lack preventing mode, a charging mode and a travelling mode. The vehicle operating state is divided into the parking mode, the ACC mode, the power on / off mode, the power lack preventing mode, the charging mode and the travelling mode, modeling management of vehicle control codes is achieved, the control logic is clearer, and the code coupling degree is decreased substantially. By adoption of the new energy electric vehicle control method, the software structure is effectively simplified, coupling relations are decreased, the vehicle control system code operating efficiency is improved, vehicle body parts are made to operate more efficiently, orderly and safely, the vehicle performance is improved, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle control method for new energy electric vehicles. Background technique [0002] As the core component of new energy vehicles, the vehicle controller (VCU) directly affects the performance of the vehicle control system. Functions such as processing and processing, vehicle status and monitoring play a key role. [0003] Establishing the vehicle system control mode and optimizing the control strategy is the key to realize the safe, stable and efficient operation of pure electric vehicles. According to different control requirements, enter different vehicle control modes, and adopt different control strategies for each component, on the basis of satisfying the driver's intention, the basic technical performance requirements of the car's power, ride comfort, economy, safety, etc. , Simplify the vehicle control logic as much as possible, use the idea of ​​modular d...
