基于LabVIEW的汽车传动试验台测控系统设计

In this paper, a measurement and control system based on LabVIEW is designed in order to measure the vibration of the drive shaft, to monitor the status of the powertrain and to control the test at specific conditions. The system consists of torque sensor, CAN interface, data acquisition card and chassis based on NI PXI. The system can acquire the torque and rotational speed of the drive shaft, monitor the status of the powertrain and control the accelerate pedal with fuzzy control method to control the vehicle speed. The experimental results show that the measurement and control system can achieve the desired function and provide the basis for the follow-up control strategy development and vibration analysis.
