In this paper, we propose a vehicle motion control method considering stability at the limit state using nonlinear model predictive control. In order to consider the vehicle limit state, a vehicle model is defined by using a nonlinear tire model that considers combined slip etc. The steering angle and the slip rates of each wheel at the limit lateral acceleration state are calculated on the numerical simulations. In addition, as an application example of the proposed method, results of running a circuit course at the fastest speed using curvature minimum path generation algorithm is demonstrated. Simulation results show that the proposed method can run at the speed at the lateral acceleration limit according to the course shape and it is able to run on the out-in-out trajectory.
