The invention provides an electrically-driven four-wheel-drive control method, an electrically-driven four-wheel-drive architecture system and a new energy vehicle, relates to the technical field of new energy vehicles, and solves the technical problem that the endurance of a four-wheel-drive electric vehicle is lower than that of a two-wheel-drive electric vehicle. The electrically-driven four-wheel-drive architecture system is of a front-rear double-permanent-magnet four-wheel-drive architecture and comprises a front permanent magnet motor installed on a front axle to form a front drive; the rear permanent magnet motor is provided with a disengagement device and is mounted on the rear shaft to form a rear drive; the front permanent magnet motor and the rear permanent magnet motor are both of a non-platform design structure, and the power and torque of the front permanent magnet motor and the rear permanent magnet motor are different. The four-wheel-drive structure with the front permanent magnet and the rear permanent magnet is adopted, the power and the torque of one motor are remarkably large, and the motor is provided with a disengaging device and is mainly used in a relatively low-speed application scene, namely rear drive; the power torque of the other motor is obviously small, and the other motor is installed on a front axle, namely a front drive, has the advantage of being high in efficiency at high speed and is in a driving or feedback state all the time, so that the endurance mileage of a four-wheel-drive vehicle type is better than that of a two-wheel-drive vehicle type with the same electric quantity.
本发明提供了一种电驱动四驱控制方法、电驱动四驱架构系统及新能源汽车,涉及新能源汽车技术领域,解决了四驱电车续航低于两驱电车续航的技术问题。该电驱动四驱架构系统为前后双永磁四驱架构,包括前永磁电机,安装在前轴,以形成前驱;带有脱开装置的后永磁电机,安装在后轴,以形成后驱;所述前永磁电机和所述后永磁电机均为非平台化设计结构,二者的功率、扭矩不同。本发明采用前后双永磁的四驱架构,两台电机的功率、扭矩一台显著偏大,带有脱开装置,主要在相对低速应用场景使用即后驱;另一台电机功率扭矩显著偏小,安装在前轴即前驱,具有高速时效率高的特点,一直处在驱动或回馈状态,使得四驱车型的续航里程优于同电量的两驱车型。
