Patent number: 11958365Abstract: The present disclosure discloses a method for dual-motor control on an electric vehicle based on adaptive dynamic programming. First, total torque required is calculated based on obtained data information of the electric vehicle under various driving conditions, and offline training is conducted on an execution network and an evaluation network. Then total torque is dynamically distributed for two motors of the electric vehicle under various driving conditions to obtain an efficiency MAP database. Afterwards, iteration and online learning are conducted on the execution network and the evaluation network based on data information of the electric vehicle under different driving conditions that is obtained in real time, so as to find an optimal control law for the electric vehicle under a real-time driving condition. In this way, the dual-motor control on the electric vehicle is optimized.Type: GrantFiled: December 9, 2020Date of Patent: April 16, 2024Assignee: JIANGXI UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Hailin Hu, Fu Feng, Chen Chen, Yue Zhang, Wen Li, Heng Shi
