Abstract: A 4×4 hybrid electric drive scheme based on 1-ton military wheeled vehicle was proposed to satisfy the special requirements of military vehicle. It consists of engine-generator group, electric power converter, battery and AC (alternate current) motor, and the corresponding matching calculation of its main components was implemented. On that basis, a distributed electric drive control system based on CAN bus network was also developed. The control system not only realizes the electric differential function when vehicle is steering, but also provides a multi-standard power source and three driving modes. The experiment results show that what the scheme not only satisfies the requirements of strong power and multi-function, but also has a higher reliability.
