Abstract

The invention relates to a mixing-power vehicle power system with power source of fuel oil and electric energy resource. It contains a motor, a gear box, a power electric battery and electrically-controlled clutch. And it also contains a motor side-generator, the rotor connecting with crank outlet of the motor and the driving element of the electrically-controlled clutch simultaneously. And it contains a gear-box side-generator, which connects with the inlet shaft of the gear box and the driven shaft element of the electrically-controlled clutch simultaneously. Said two generators are powered by the power electric battery, and connect separately with two generator controllers and are controlled by them. And the device contains a central controller, which connects with and controls the electrically-controlled clutch, the power electric battery and said two generator controllers.

Description

【Technical field】 [0001] The invention relates to a hybrid electric vehicle power system using fuel oil and electric energy as power sources, in particular to a hybrid electric vehicle power system with pure electric driving capability. 【Background technique】 [0002] Due to the environmental pollution and energy consumption of fuel-powered vehicles, electric vehicles and hybrid vehicles have become one of the hot spots in the development of the automotive field. [0003] The power system structure forms of the existing hybrid electric vehicle have three forms: series connection, parallel connection and hybrid connection. For example, the IMA parallel system of Honda's Insight, and the THS hybrid system of Toyota's Prius. Among them, the IMA system of Honda's Insight has a simple structure, but the motor only has the power assist function, and does not have the pure electric driving capability, which is a weak hybrid form. The THS hybrid system of Toyota's Prius is capable...
