Abstract: A motor driving system and a motor driving method adapted to an electric bicycle are provided. The motor driving system includes a sensing device, a front driving motor, a rear driving motor, a front driving device, and a rear driving device. The sensing device generates sensing information. The front driving device drives the front driving motor according to the sensing information. The rear driving device drives the rear driving motor according to the sensing information. When the motor driving system is powered-up, the front driving device and the rear driving device respectively perform a master-slave query operation to each other, and it is determined that one of the front driving device and the rear driving device includes a master controller according to a result of the master-slave query operation.

Abstract: A method for searching an electronic device and an electronic device are provided. The method includes following steps. A request packet that is broadcasted by another electronic device according to a wireless communication protocol is received. It is determined whether the electronic device matches a target device indicated by the request packet according to target identification information in the request packet. If the electronic device does not match the target device indicated by the request packet, another request packet is generated and broadcasted according to the wireless communication protocol. If the electronic device matches the target device, indication for indicating location information of the electronic device is supplied.
