Multiple energy source bench arrangement scheme for mixed power electric automobile

Abstract

The present invention relates to a multi-energy table arrangement scheme of mixed power electric automobile, and is implemented by adopting the following measures: A. enigine is connected with speed change box by means of clutch, main motor is connected on the rear end of speed change box, the power is passed through speed change box and differntial mechanism to make two-way output, said outputs can be synthesized into one shaft output so as to implement connection of power-measuring machine and power system; and B. enignine throttle controller ECU1, ISG controller ECU2, AMT controllers ECU3,main motor controller PMU and power supply management system BMU are connected with whole vehicle controller, then the table control system can transmit and receive signal to whole vehicle controller.

Description

technical field [0001] The invention belongs to the automobile test technology, in particular to a hybrid electric vehicle multi-energy power assembly test stand. Background technique [0002] Hybrid electric vehicle has attracted more and more attention because of its low emission advantages of electric vehicles and high specific energy advantages of internal combustion engine vehicles, and has become one of the new vehicles to be developed. Since the 1990s, major automobile companies in Japan, the United States, and Europe have begun to develop hybrid vehicles. Japan's Toyota Motor Corporation took the lead in putting the hybrid prius sedan on the domestic market in December 1997, Honda launched the Insight hybrid sedan, and Nissan launched the Tino hybrid car. In the United States, the three major automakers are scrambling to launch their own hybrid vehicles. For example, Chrysler's ESX3, Ford's P2000, GM's Gen2, etc. [0003] Since a hybrid vehicle includes at least t...

Problems solved by technology

[0004] In order to solve the problem that the bench test scheme directly connected with the engine and the dynamometer can no longer meet the requirements of the test, the present invention proposes a hybrid electric vehicle multi-energy powertrain test bench, which is characterized in that: the bench The engine is connected to the gearbox through the clutch, the main motor is connected to the rear end of the gearbox, the gearbox is connected to the transmission through the differential, and the transmission is connected to the dynamometer; engine throttle controller ECU1, ISG controller ECU2, AMT The controller ECU3, the main motor controller PMU and the power management system BMU are all connected to the vehicle controller, and the bench control system that sends and receives signals to the vehicle controller is connected to the vehicle controller
