Abstract

The invention discloses a transmission and a control method of a vehicle hybrid power system, including an engine assembly, an auxiliary motor, a drive motor, a power input shaft, a first power output shaft, a second power output shaft, a differential and a storage battery; The control method consists of seven control modes, including pure electric drive mode, pure power drive mode, hybrid drive mode, full power output mode and energy recovery mode, and the gear shift component adopts a two-speed configuration. Beneficial effects: the present invention can make more full use of the performance of the auxiliary motor and the driving motor, so that the working range of the engine assembly can be further optimized, and at the same time, the full use of the motor can effectively improve the working efficiency of the entire system; the two-speed configuration is further simplified The internal structure of the transmission frees up space and saves costs; the mechanism of the first synchronizer is added to the arrangement of the auxiliary motor, which increases the working mode of the auxiliary motor and makes the entire system work more smoothly.

Description

technical field [0001] The invention relates to a transmission and a control method, in particular to a transmission and a control method of a vehicle hybrid power system, belonging to the technical field of the transmission system of the hybrid power vehicle. Background technique [0002] With the increasing global consumption of fossil energy, human beings are facing more and more serious problems of environmental pollution and resource depletion. As the most important means of transportation, automobiles consume a lot of oil resources every year, and with the development of the economy, the number of automobiles will continue to increase. How to reduce the consumption of oil resources and the impact of automobiles on the environment has been paid attention to by major automobile companies and governments of various countries. Today's automobile industry is under great pressure. Hybrid electric vehicles have become the focus of automobile research and development due to t...
