<；P>；PROBLEM TO BE SOLVED: To provide an auxiliary driving device for a wheelchair. <；P>；SOLUTION: The auxiliary driving device for the wheelchair includes a wired signal transmission structure, a sensor, a control circuit and a driving unit. The wired signal transmission structure is set in a hub, and the hub is set in a wheel of the wheelchair. The sensor is set in the wheel, and generates a detection signal to be transmitted to the wired signal transmission structure. The control circuit is connected to the wired signal transmission structure to receive the detection signal, and generates a control signal. The driving unit is connected to the control circuit to receive the control signal, and drives the hub based on the control signal to rotate the wheel. With this structure, the auxiliary driving device is simple-structured, transmits signals by a wired transmission system, hardly receives the interference of the external environment, and securely transmits the detection signal to the control circuit. As a result, the driving unit is accurately controlled to drive the wheel, and the cost can be reduced by the wired transmission system. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
