The driving simulator is displayed with three screens, include TDOF (three degree of freedom) Movement platform, real car imitated driving cabin, manual driving equipments (force feedback steering wheel, throttle, brake, gears, instrument board, etc.). The tester can operate the simulated vehicle, and the driver's driving behavior can be collected by computer and UC-win/Road software, with automatically generated table saved in the computer. In the research of vehicle development and optimization, import the designed completed vehicle dynamics or adjust the vehicle dynamics embedded in the software. We can test and verify the power design rationality of new vehicles by the data collected by driving simulator, such as vehicle driving speed, click parameters, operation of steering wheel, stepping down extent of accelerator pedal and brake pedal, power consumption, and so on.
