PROBLEM TO BE SOLVED: To hinder occurrence of torque change sensed by a passenger, by maintaining a short period of switching between the energization of the coil of a dynamo and its stop by means of a regulator.SOLUTION: When the output of a dynamo is adjusted via a regulator by energizing the coil of the dynamo when a battery voltage is lower than a directed voltage and by stopping magnetization through stopping energization to the coil when the battery voltage is higher than it, a required target voltage is usually directed to the regulator. On the other hand, when the period of switching between the energization to the coil and the stop of it is longer than a predetermined one, a high level voltage, which is higher than the target voltage, and a low level voltage, which is lower than the target voltage, are alternately directed to the regulator. Additionally, the period of switching between the high level voltage and low level voltage is made shorter than the predetermined one. |
