AI Technical Summary

Technical Problem

During the research and development process, hybrid electric drive assembly needs to rely on a high-cost three-dynamic dynamometer bench for testing, resulting in higher testing costs and cycles.

Method used

By providing a hybrid electric drive assembly test method, the control system and actuator of the hybrid electric drive assembly are detected by using low-voltage power supply and high-voltage power supply, and the test program is run based on the target test environment and parameters to obtain the target test results to determine whether the test is passed.

Benefits of technology

Without relying on the three-dynamic dynamometer, functional testing of the hybrid electric drive assembly was completed, reducing the test cost to about one-tenth of the three-dynamometer cost, and shortening the test cycle to about half a day.
