With the rapid development of electric vehicle technology, the vehicle controller, as the core of the vehicle system, plays a crucial role in achieving efficient, safe, and comfortable driving experience through its drive mode control function. Firstly, the requirements for driving mode control functions were clarified, including multiple modes such as normal driving, braking energy recovery, and fault protection. The driving modes of pure electric vehicles can be divided into neutral mode, driving mode, parking mode, limp driving mode, and anti-skid mode. Among them, the driving mode is subdivided into forward driving mode and reverse driving mode. Each driving mode is divided into Drike mode, Break mode, and energy recovery mode. In the sensor and signal acquisition stage, key data such as accelerator pedal position, brake pedal force, vehicle speed, motor speed, battery status, etc. are obtained in real time through sensors arranged in various key parts of the vehicle, providing a basis for the formulation of subsequent control strategies. In the control strategy design section, based on knowledge from multiple fields such as vehicle dynamics, battery management, and motor control, reasonable control algorithms have been developed to ensure that the vehicle can maintain optimal driving performance under different operating conditions.
