Abstract
<div class="section abstract"><div class="htmlview paragraph">To investigate the rollover phenomena experienced by all-terrain vehicles (ATVs)
during their motion caused by input from the road surface, a combined simulation
using CarSim and Simulink has been employed to validate an active anti-rollover
control strategy based on differential braking for ATVs, followed by vehicle
testing. In the research process, a nonlinear three-degrees-of-freedom vehicle
model has been developed. By utilizing a zero-moment point index as a rollover
warning indicator, this approach could accurately detect the rollover status of
the vehicle, particularly in scenarios involving low road adhesion on unpaved
surfaces, which are characteristic of ATV operation. The differential braking,
generating a roll moment by adjusting the amount of lateral force each braked
tire can generate, was proved as an effective method to enhance rolling
stability. Simulation and on-road testing results indicated that this control
strategy effectively monitored the state of the ATV and enhanced the stability
during rollover tests.</div></div>
