Study On The Measurement And Control System Of Vehicle Integrated Powertrain Test Bench

Using hydro-mechanical Continuously Variable Transmission (HMCVT for short)and hydro-mechanic differential turning system can effectively improves thetransmission efficiency and turning performance of trackle vehicle to perform thesteeples speed changes. Study on the integrated powertrain test bench, develop itsmeasurement and control system, establish the evaluation method performance,improve the accuracy and level of the test system’s automatic test and control, whichhas important theoretical significance and practical value for the theoretical researchand application in engineering equipment.Combined the national standard with the discussion of home and abroad tracklevehicle integrated powertrain’s current situation and growing trend. Completed theoverall structural design, finished the major components of the test bench selection,combined with the measured object characteristics of the development work based onCAN technology. According to measurement and control system characteristics,carried out monitoring and control system hardware configuration, while analysis itsmain components control methods. On the basis of LabVIEW virtual instrumentsoftware as the test bench’s main software, completed power loss under no load testand rev characteristic under load test as examples of the system debug. The resultsshowed that: the integrated transmission control system is operating normally withHMCVT and hydro-mechanic differential turning system performance testingrequirements, provided basis for the HMCVT and hydro-mechanic differential turningsystem’s improved design and theory evidence.
