Technology first! BAIC Group won the first patent in the field of electric vehicle control. How to apply for this patent?

This patent provides a method for estimating the mileage of electric vehicles and managing energy. The driver's driving habits, the current state and attenuation of the power battery are introduced into the driver model in quantitative form, and the accurate estimation of the remaining driving range of the vehicle is realized by calculating the compensation factor, which solves the defect of low accuracy of the traditional driving range estimation method based on linear model and greatly improves the estimation accuracy.

The electronic control system of intelligent vehicle is a very important part of the whole vehicle control process. Especially in the new energy vehicle industry, especially in the pure electric vehicle industry. The control system is mainly composed of VCU, ADAS, braking system, EPS and central control system. According to the main parameters of two kinds of electric vehicle drive systems, the simplified mathematical model of the controlled object is established, and PID controller, adaptive controller, fuzzy controller and predictive controller are designed, and their control performance is compared and analyzed through numerical simulation. ?

Ac motor will still be the first choice for the motor drive system of electric vehicles in the future. Its control system will be continuously optimized with the development of power electronics technology, and the control device and technology of AC motor will also be continuously developed. With the development of modern control theory, various modern control technologies and microprocessors have played an important role in the drive control system of electric vehicles. The dynamic control system of electric vehicle is bound to develop in the direction of interdisciplinary and integration, and become an intelligent system with electromechanical integration.

You should know that the energy management system can control the charging mode, display the current remaining power and realize the charging reminder. However, the function of data acquisition module requires accuracy, reliability and safety. Through the comprehensive monitoring of the acquisition module, the battery is always in working state, and the state of the battery can be monitored in real time to prevent overcharging, thus effectively improving the service life and utilization rate of the battery pack. After the battery fails, it can be repaired in time, which greatly improves the operating efficiency and safety of the battery.
