Abstract

Aiming at the problems that the data acquisition was not synchronized,the test efficiency was low and the analysis and save of subsequent data were difficult,the scheme of cold start test data acquisition and analysis system for commercial vehicle was proposed. The cold start test platform of the target vehicle was built to solve the problems that the target vehicle was difficult to start about- 35 ℃,and the fuel consumption and emission was too high during the cold start. The cold start tests were carried out between- 25 ℃ and- 35 ℃based on the test platform. The cold start test data of several temperatures were collected. The temperature was used as threshold to control the fuel oil heater in the test. The cold start control strategy of the target vehicle was optimized based on the test results. The effectiveness of the optimization strategy was verified by user test for one year,and the availability of the data acquisition system was proved.
