Testing system and method for AMT hybrid power driving mode gear shifting execution mechanism

Abstract

The invention discloses a test system and method for an AMT hybrid power drive mode gear shifting execution mechanism. The test system comprises a test system and a control unit. The test system comprises a first resistance providing unit, a first air flow control unit and a second air flow control unit. A first displacement sensing unit and a second displacement sensing unit are arranged in the first resistance providing unit; a first air pressure sensing unit is arranged between the first air flow control unit and the first displacement sensing unit; a second air pressure sensing unit is arranged between the second air flow control unit and the second displacement sensing unit; the control unit comprises an upper industrial control unit and a lower control unit; the upper industrial control unit, the lower control unit and the gear shifting execution mechanism to be tested are in communication connection; the system is also provided with a signal acquisition and control channel module. The system is reasonable in design, simple in structure, convenient in test operation, high in test efficiency and low in cost, and a perfect test system of the gear shifting execution mechanism in the AMT hybrid power driving mode is formed.

Description

technical field [0001] The invention belongs to the testing field of a shift control unit, and relates to a testing system and method for a shift actuator in an AMT hybrid driving mode. Background technique [0002] As the international community pays more and more attention to energy security and environmental protection issues, countries have increasingly stringent requirements on vehicle emissions. Reducing dependence on energy and realizing energy conservation and emission reduction has become an urgent problem to be solved for the sustainable development of the world economy. Therefore, hybrid electric vehicles and pure electric vehicles have become the development trend of today's automobile industry. Among them, the shift control of the AMT automatic transmission is one of the key technologies in the field of hybrid electric vehicles, and it is also constantly developing and improving. In the process of shifting gears of hybrid electric vehicles and AMT automatic tr...

AI Technical Summary

Problems solved by technology

In the process of shifting gears of hybrid electric vehicles and AMT automatic transmissions, it is easy to cause impact on the vehicle. The selection of gears in the transmission system will affect the working status of the engine and motor, thereby affecting the dynamic performance of the vehicle.

At this stage, the test of the shift actuator in the AMT hybrid drive mode is still in the exploratory stage, there is no mature and perfect test system, and there is a lack of a large amount of test data to support the evaluation of the impact of the transmission shift
