The embodiment of the invention provides a power control method and system. The method comprises the steps of receiving rotating speed and output torque information of a motor sent by a motor controller; according to the rotating speed and output torque information of the motor, controlling a second clutch and a planetary gear set to be kept in connection and performing power transmission under the drive of the motor, controlling disconnection of a first clutch and the planetary gear set, and controlling combination of a third clutch and the planetary gear set after the first clutch and the planetary gear set are disconnected to complete gear switching. The whole performance of the power control system in an electric vehicle can be effectively improved, and power consumption of the motor is lowered.
Description
technical field [0001] The present invention relates to the technical field of new energy vehicles, in particular to a power control method and system. Background technique [0002] At present, the power system of pure electric pickup trucks mainly adopts the direct drive mode of the motor or the driving mode of the motor and the gearbox. However, these two driving modes are driven by a motor with high torque and low speed, resulting in high cost of the motor and high efficiency. The area is narrow. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a power control method and system to improve the above problems. [0004] A preferred embodiment of the present invention provides a power control method applied to an automatic transmission control unit connected to an automatic transmission, the automatic transmission includes a planetary gear set, a first clutch, a second clutch and a third clutch, so T...
