Abstract

The embodiment of the invention provides an automatic variable speed control system of a pure electric vehicle and a pure electric vehicle. The automatic variable speed control system comprises an entire vehicle controller, a drive motor, a transmission, a power assembly controller and a gearshift, wherein the entire vehicle controller is used for generating control information, and the control information comprises a target torque and a target gear; the power assembly controller is used for obtaining the control information, controlling the target torque to control the drive motor to output a torque and a rotating speed, and controlling the gearshift to drive the transmission to adjust a gear according to the target gear; and the drive motor drives the transmission to operate according to the torque and the rotating speed. According to the technical scheme provided by the embodiment of the invention, requirements of large starting torque of the vehicle, high motor operating efficiency and wide working range can be satisfied.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, and more specifically relates to an automatic transmission control system of a pure electric vehicle and a pure electric vehicle. Background technique [0002] With the continuous development of pure electric vehicles, users have higher and higher requirements for the performance of pure electric vehicles, which is not only reflected in the driving performance of pure electric vehicles, but also in the power, economy, driving comfort and performance such as handling stability. [0003] As one of the core components of pure electric vehicles, the electric drive system is configured in such a way as to determine the above-mentioned performances. [0004] At present, most pure electric vehicles use a drive motor combined with a single-stage deceleration power transmission structure, which cannot meet the requirements of large starting torque, high motor operating efficiency and wide ...
