An intelligent auto-driving system by interactive acquisition of driving knowledge as information on route

For senior citizens and physically handicapped persons who use a welfare electric cart, an auto-driving system is effective to reduce stresses of driving operations. However, the system requires information on route to reach the destination. Furthermore, the system should be able to be treated without difficulty for users. In this paper, the system interactively acquires driving knowledge composed of landmark´s information and action rules as the routing information from users, and drives a cart flexibly to the destination by using the driving knowledge and the operation knowledge of four-wheeled vehicle. Results of auto-driving experiment by human´s riding show the effectiveness of the system.
