Problems solved by technology

[0007] In view of the above analysis, the present invention aims to provide a hybrid electric vehicle power system and method with four wheels independently controllable. By using the motor to control the wheels separately, it effectively solves the problem that the existing vehicles cannot control the output torque of the four wheels. The problem that the speed can be controlled independently improves the efficiency and safety performance of the vehicle during driving

Abstract

The invention relates to the technical field of power transmission systems of hybrid power vehicles, in particular to a four-wheel-independently-controllable distributed drive hybrid power electric car power system. The system mainly comprises a motor, a power generator, an engine, a brake, a planetary gear mechanism, a clutch and a planetary gear rack, wherein the output shaft of the engine on a front drive axle is connected with the planetary gear rack of the planetary gear mechanism through the clutch and connected with the brake. The invention further provides an application method of the four-wheel-independently-controllable distributed drive hybrid power electric car power system. The four-wheel-independently-controllable distributed drive hybrid power electric car power system has the advantages that by the planetary gear mechanism, vehicle controllability and stability are increased, and vehicle energy utilization efficiency is increased; the difficulty that an existing vehicle cannot independently control the output torque and rotation speed of the four wheels is solved, and the unmature market space of electric cars is filled up.

Description

technical field [0001] The invention relates to the technical field of a power transmission system of a hybrid vehicle, in particular to a power system of a hybrid electric vehicle with independently controllable four wheels and a method thereof. Background technique [0002] The electrification and intelligence of automobiles have become the direction of change in the vehicle field. Under this general trend, "safety" and "high efficiency" are the focus of attention. [0003] Distributed drive technology is a research hotspot under the topic of "safety". First, compared with the traditional dynamic stability control system (ESP), distributed drive vehicles, that is, torque vector distribution control, can further expand the controllable range of the vehicle, which balances the road adhesion utilization of each tire , which increases the stability margin of the vehicle; second, in the distributed drive system, the four tires of the vehicle can be independently controlled and...
