Research on Motor Speed Control Method Based on the Prevention of Vehicle Rollover

Vehicle driving safety is an important performance indicator for vehicles, and there still much room development in the active control of electric vehicles. Vehicles are susceptible to rollover when making sharp turns or overtaking at high speed. In order improve anti-rollover stability vehicles (EV), this study proposes a real-time motor strategy, mainly according acquisition vehicle attitude data monitoring vehicle’s operating state. The lateral load transfer rate was defined as evaluation index. When exceeded limit threshold article set, speed would be reduced through avoid reduce risk rollover. Both simulation results Carsim Simulink showed that strategy highly reliable capable, EV improved significantly.
