Test Bench Construction of Active Steerbywire for Rollover Research

Abstract:

In order to study the rollover control through active steerbywire system, a suitable test bench was requested. First, a hardwareintheloop experiment platform structure of active steerbywire for rollover was analyzed. The vehicle model, experiment management software and hardware platform were established. The hardware platform was composed of steering system, torque simulation loading device with magnet brake and data acquisition device. On the condition of 75° steering wheel angle of pulse test, 25° steering wheel angle of step test, 20 km?h-1 speed of Jturn test, 80 km?h-1 speed of double lane change test and 70 km?h-1 speed of snake test rollover angle of vehicle body which was used to characterize roll degree in the simulation and experiment were monitored. Results of which are close to each other. It indicates the applicability of the test bench for the rollover test.
