摘要
When the hybrid cars driving in the crowded city,frequent starting of the engine is inevitable and the driving performance in engine starting process is t-he key indicator of the customer' s evaluation of the vehicle.In this paper,a systematic analysis of the engine starting process is carried out for a P2 configuration hybrid electric vehicle.Based on the above theoretical research,a kind of evaluation method is developed,which can be objective and reproducible to evaluate the driving performance of vehicle during the engine starting process.Based on this method,the test is carried out on the powertrain testbed.The test results show that the method is correct.It is the key way to evaluate the driving performance of engine starting process,and it is also an important basis for the selection of the engine starting strategy.
