This paper aimed at developed a power source with the combinaiton of an air motor and a servo motor. The test bench was used to measure the performance curvers and characteristics. The Matlab/Simulink software package was to establish the simulator of the air/electric hybrid powertrain while to analyze the vehicle performance. This research studied the air motor module, the servo motor module, the lithium battery module, the transmission, the energy management strategy, and the driving patterns. The rule-based control strategy was developed; the parameter calibration and rule modification were conducted. The results of simulation and data from the real test were consistent, which indicated that this simulation platform and this approach of performance verification reduces the development period and the cost of trial-and-error experments.
