In order to meet the requirements for human machine optimization design, the dynamic test system was designed based on the chassis dynamometer, which was used to evaluate the parking brake performance of passenger vehicle. Firstly, the feasibility analysis was conducted for the test scheme, and the test model for the equivalent angle of parking slope was put forward. Then, the test system was designed, in which the CompactRIO (cRIO) controller and the related C modules made by National Instrument Company of America were selected as the core components. Under the consideration of the general installing requirements, both the handle force sensor and the angle sensor were selected, and their related mounting brackets were designed. Besides, the LabVIEW was employed to program the code for the controller and the host computer, in which the functions, such as data collection, data processing, communication and GUI, were conducted reliably in real time. Thirdly, the test method was explored, in which these influence factors were taken into consideration, such as elastic elements rebound, surface state of brake drum or disk, processing technology. In particular, the method of probability and statistics were introduced to evaluate the parking brake performance. Finally, the test system was used to conduct several tests and it worked reliably, and it met the design requirements. The result showed that it was effective and plausible for the dynamometer based test system and the evaluation method proposed for the parking brake performance of passenger vehicle.
