Abstract

Shared control is a common used method for human and wheelchair cooperation. However, most of the previous shared control methods didnít think much of the effect caused by the difference in the userís control ability. The control weight of a user in these methods is irrelevant to the userís capability or the driving conditions. In this paper, a dynamic shared control method is proposed to adapt wheelchairís assistance to the variations of user performance and the environmental changes. Three evaluation indices including safety, comfort and obedience are designed to evaluate wheelchair performance in real time. A minimax multi-objective optimization algorithm is adopted to calculate the userís control weight. The results of lab experiments and elderly home field tests show that this method can adapt the degree of wheelchairís autonomy to the userís control ability and it makes driving wheelchair much easier for elder people.
