Real-time Acquisition and Analysis Test Data of Commercial Vehicle Handling Stability Based on LABVIEW Virtual Instrument

Abstract

Aiming at the problems of complex time-consuming and heavy data processing workload in the field test of commercial vehicle handling stability, a vehicle handling stability test solution based on virtual instrument technology is proposed. This solution is based on the existing test equipment and conditions, using LABVIEW virtual instrument, integrated application of GPS, AHRS and steering force angle tester to form a set of road test system solutions that can realize vehicle handling and stability. The system can meet the requirements of the national standard Controllability and Stability Test Procedure for Automobile (GB / T 6323-2014) to realize the vehicle handling stability test, and the system test is verified by the real vehicle test data, which provides a more efficient and convenient test method for the study of vehicle handling stability test.
