Expectations are rising for four-wheel independently steered vehicles due to their high degree of freedom. However, inputting an appropriate steering angle to each wheel is necessary. Therefore, we propose a path-tracking control method for four-wheel independently steered vehicles using the pure pursuit method. The pure pursuit method is used as a path-tracking algorithm for self-driving cars because of its ease of implementation, but the method must be applied to turning movements by various independent steering patterns of four-wheel independently steered vehicles.
Therefore, we develop a new pure pursuit method that enables the steering angle ratio of the front and rear wheels to be changed and allows the center of the vehicle to follow the path. The simulation results showed that the proposed method enabled a four-wheel independently steered vehicle to follow the road under any steering angle ratio of the front and rear wheels. By adjusting the look-ahead distance, we confirmed that the vehicle did not deviate from the road width. In addition, we confirmed that when the curvature of the road changed significantly, a contradictory relationship existed between the vehicles path-tracking performance and the magnitude of the vehicle's lateral acceleration.
