LabVIEW Based Data Analysis for Automotive Steady Static Circular Test
Motor vehicle’s controllability and stability were its fundamental performances, of which the steady state circular test (i.e. SSC) was most important, and become the basis of motor vehicle’s dynamics stability control. In this paper, two group of typical SSC data of one motor vehicle were employed and processed by the graphical programming language LabVIEW software, then the curves (Ri/Ro)-ay, (1-2)- ay and - ay were obtained. According to the curve analysis and related rules and regulations, the lateral acceleration of neutral steering an, understeering gradient U, and the vehicle body rolling rigidity K were resolved, so we could get the motor vehicle’s SSC performance comprehensive evaluation value. The work in the paper constructed a platform for vehicle’s controllability and stability study conveniently and efficiently.
