The invention relates to a whole vehicle controller power system control technology in the field of new energy vehicles, and mainly solves a problem of power output control of a large-transportation new energy four-wheel-drive electric vehicle ES3. By testing and calibrating working states and output torques of front and rear driving systems, torque control under various working conditions such asdriving travel and energy recovery is reasonably configured. The method comprises torque driving control in different driving modes and energy feedback control in different modes. The vehicle drivingmode is divided into three modes, namely, an ECO mode, a NORMAL mode and an SPORT mode. Optimal control over the torque of the electric vehicle is achieved through a torque driving control method anda filtering algorithm of the electric vehicle of the dual-drive bridge architecture in different driving modes, the energy feedback entering and exiting control algorithm of the electric vehicle of the dual-drive bridge architecture and the torque Map of the electric vehicle of the dual-drive bridge architecture in different driving modes.
