IPC: G05D1/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To track a route constituted of a directed straight line and a directed circular arc by a non-holonomic moving vehicle. SOLUTION: This control method is not only simple but also suitable for a real time application and controls the smoothness of a track by using a 'steering function' and a 'neutral transition principle' for realizing the motion of a continuous curvature and minimizing sliding between a ground surface and a wheel. The system is constituted of a 'sub system independent of the moving vehicle' and the 'sub system dependent on the moving vehicle'. The 'sub system independent of the moving vehicle' usable for the different moving vehicles in common is further separated into the four sub systems of a moving vehicle coordinate system updating sub system, a route buffer sub system, a continuous curvature motion control sub system and a segment transition sub system.
