The data acquisition system includes: a data collector, a computer, and data acquisition software. The data collection system can collect the force value and displacement signal of the position of the ball head 71 of the shift rod 70 of the shifter assembly 3 . The data collection system can collect the force value and displacement signal of the clutch pedal 75 of the clutch pedal assembly 5 .

During the static test, the tester sits on the seat assembly 2, manually manipulates the shift lever force sensor 13 installed at the position of the shift lever ball on the shifter 3 as required, and then steps on the clutch pedal as required The pedal force sensor 15 installed on the clutch pedal 75 position on the assembly 5 completes the test operation.

Through the communication connection between the data collector and the computer and the data collection software installed on the computer, testers can view the collected signals in real time on the computer. Through the data analysis software on the computer, the testers can analyze the collected data accordingly, and save the collected data on the computer hard disk.
