Abstract:

A simulation method for identifying the force input in vehicle handling inverse dynamics is proposed under the condition of different vehicles tracking the same given path. In this method , a linear model of steering torque input for the vehicle with three degrees of freedom is adopted , and the optimal control theOIγis used to identify the steering torque input. By using the direct parallel method , the optimal control problem is converted into a nonlinear programming problem that is then solved by means of the sequential quadratic programming. Simulated results show that the proposed method is of good path-tracking ability and is able to compare the maneuverability of different vehicles that track the same path.

Key words: vehicle handling dynamics, optimal control, inverse problem, simulation
