Problems solved by technology

[0004] For new energy vehicles, most of them use a single motor plus a single-stage deceleration mechanism. The single motor has high power and high energy consumption. When the vehicle is at high speed, the motor speed is high, the efficiency is low, and the energy consumption is large. High-speed energy saving cannot be taken into account. Therefore, the speed range of the motor design is large, and new energy vehicles generate high energy consumption at high speeds.

Abstract

The invention discloses a stepless speed change system (1) for a new energy vehicle, which comprises a shell (101), and further comprises a transmission shaft (102) rotatably arranged in the shell (101); a planetary gear mechanism coupled to the transmission shaft (102); at least one electric machine, the at least one electric machine being coupled to the planetary gear mechanism; and the controller is used for controlling the operation of the at least one motor, and the stepless speed change system (1) is configured to realize the stepless change of the rotating speed of the transmission shaft (102) through the operation change of the at least one motor and the planetary gear mechanism. The invention further provides the new energy vehicle and a stepless speed change method for the new energy vehicle. According to the stepless speed change system and method for the new energy vehicle, the energy efficiency of the vehicle at a high speed is improved, and the low-speed large torque and high-speed energy saving requirements can be met.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle transmission system and method for new energy vehicles, in particular to a continuously variable transmission system for new energy vehicles and a continuously variable transmission method for new energy vehicles. Background technique [0002] With the rapid growth of automobile sales, energy problems and environmental pollution problems are becoming more and more serious, and the development of energy-saving and environment-friendly automobiles is one of the effective ways to solve the above two problems. [0003] In recent years, the new energy automobile industry has developed vigorously, and electric vehicles have gradually entered ordinary families. In addition to the huge difference in power output between new energy vehicles and traditional fuel vehicles, there are also major differences in power transmission. The traditional fuel vehicle uses a cont...
