Once the digital output signals are processed by a processor embedded within the controller, the processor may issue a control command to the electric machine. The processor may have memory containing software to make the processor execute the computation of the control command of the electric machine in accordance with a torque command. | 2014-03-20 |
20140077740 | ELECTRIC BICYCLE DRIVING APPARATUS - Disclosed is an electric-bicycle driving apparatus. The electric-bicycle driving apparatus includes a speed-change mode operator to output a low-speed or high-speed mode signal, a controller to receive the low-speed or high-speed mode signal from the speed-change mode operator and to output a first or second control-signal corresponding to the low-speed or high-speed mode signal, a generation-signal provider to provide a generation-signal output from a generator, and a motor-driver operating-signal regulator to receive the first or second control signal when the speed-change mode operator outputs the low-speed or high-speed mode signal, to regulate a level of the generation-signal output from the generation-signal provider and to provide the resulting signal to a motor driver that drives a motor, the motor-driver operating-signal regulator providing a lowered level of generation-signal to the motor driver that is operated upon receiving power of a battery, and cutting off an abnormal signal from the motor driver. | 2014-03-20 |
