Heavy hybrid power assembly testing system

Abstract

The invention discloses a heavy hybrid power assembly testing system comprising two dynamometers, an upper computer, a rapid control prototype, a motor controller, a moment-limiting clutch controller and an engine controller; the rapid control prototype is used for sending a control instruction to the engine controller, the motor controller, a battery manager, a moment-limiting clutch controller and the like; the engine controller is used for controlling an engine to rotate according to the control instruction; the motor controller is used for controlling the motor to rotate according to the control instruction; the moment-limiting clutch controller is used for connecting or disconnecting a moment-limiting clutch according to the control instruction; and the dynamometers are used for detecting a working condition signal of a transmission, sending the working condition signal to the upper computer and judging the performance of a heavy hybrid power assembly according to the working condition signal. The heavy hybrid power assembly testing system can be used for realizing convenient, rapid and effective test for the function, the performance and the reliability of the heavy hybrid power assembly.

Description

technical field [0001] The invention relates to the technical field of powertrain system testing, and more specifically, relates to a severe hybrid powertrain testing system. Background technique [0002] At present, as the world's oil resources become more and more scarce, major international and domestic automobile companies are devoting themselves to the development of new energy vehicles to advocate energy saving and emission reduction. At present, the new energy vehicles occupying a large market share in the market are severe hybrid vehicles, and the core of severe hybrid vehicles is the severe hybrid powertrain. The performance of the vehicle is tested, so as to further judge the pros and cons of the performance of the severe hybrid electric vehicle. [0003] At present, most of the tests of the performance of the heavy hybrid powertrain are to install the heavy hybrid powertrain on the whole vehicle, and then test the whole vehicle. This kind of test method is easil...

AI Technical Summary

Problems solved by technology

This kind of test method is easily limited by the space of the whole vehicle. After a fault or problem occurs, it is difficult to check the fault and replace the parts, and the workload is heavy.

At the same time, the field debugging and testing of the whole vehicle is affected by roads, weather, etc., the test period is long, the vehicle is unstable, and there are likely to be potential safety hazards
