A novel approach for optimal speed control of the vehicle using drive envelope based analysis

Abstract

Roll-over stability of a ground vehicle is often considered as an important safety factor for maneuvering of vehicle in curved trajectories. This paper deals with investigating the path of the vehicle collected from planner algorithms and generate a mathematical model depicting the speed such that the vehicle maneuvers within the safe drive envelope. The roll-over dynamic stability of the vehicle is derived by application of the forces at the vehicle CG and performing its rigid body analysis. The simulation results are based on the critical speed plot derived from rigid body model. The same model is expected to be used for controlling the vehicle speed during the curvature.
