Acceleration Mode

This paper analyzes the lateral dynamics of the vehicle withindependent suspension. The tests have been made driving inan incremental acceleration mode under conditions of a circulartrajectory within 10, 15 and 20-meter radius. The literature reviewprovides a summary of recent research re-lated to the topics discussedin this article. The article looks at the interaction of thesnowy and dry road with wheels and its influence on the lateraloscillation of a vehicle. The displacement of different sides ofvehicle suspension and its variation in acting lateral accelerationhave also been estimated. Data on the performed tests of theconducted research have been graphically plotted thus presentingthe summarized results and conclusions.

To assist vehicle rollover prevention and enhance vehicle roll motion safety, this paper proposes a novel active rollover preventer (ARPer) system, which consists of an in-wheel motor system moving along an orbit at the back of a vehicle. The roll and lateral dynamics of the vehicle equipped with the ARPer are modeled and mechanics analysis of the ARPer is presented as well. Based on the developed models, a Lyapunov nonlinear controller is designed for tracking a desired roll angle and a yaw rate when the impending rollover is detected. For a typical fishhook maneuver, two simulation cases are studied for different vehicle roof cargo loads, which represents different vehicle rollover properties without control. The CarSim®-Simulink co-simulation results show that compared with active front steering and differential braking control strategies, the APRer can successfully prevent the rollover propensity and maintain the vehicle lateral stability simultaneously.
