2.4 Vehicle control system The control system of unmanned vehicle consists of two parts. One part is a longitudinal control system. The other part is a lateral control system. Fig. 4 shows vehicle control system configuration. We used NI DAQ and NI motion in this research. And we used actuators and sensors for motion control. The DAQ part is connected with several sensors which give the vehicle states to a vehicle. It inputs acceleration signal and electronic switch signals in the vehicle as well. The motion part drives motors which connected with brake and steer.
