Abstract

Automobile chassis output power is one of the important evaluation indexes in automobile power performance testing. It is the direct embodiment of engine power transmission performance and fuel efficiency. Its performance has a direct impact on automobile transportation efficiency, stability and safety of vehicle operation and automobile exhaust emission pollution. Strengthening the research on the key technologies of vehicle chassis output power detection and developing a set of efficient, safe and accurate vehicle chassis output power measurement and control system will play a positive role in improving China's vehicle chassis output power detection technology, saving social energy and strengthening environmental protection. The actual calibration and test of the developed vehicle chassis output power detection and control system are carried out in this paper. The test results show that the system runs stably and reliably, and the detection and control accuracy and sampling real-time meet the requirements of relevant national detection standards and practical engineering applications.
