Abstract
A shift device includes: a motor drive circuit; a motor driver unit for driving the motor drive circuit; a control unit that controls the motor driver unit; a motor power supply path; a system power supply path; and a buck-boost unit that converts electric power supplied from the system power supply path to a predetermined voltage and outputs the voltage. Electric power is supplied to the control unit via the buck-boost unit, and either the electric power from the motor power supply path or the electric power from the system power supply path is supplied to the motor driver unit based on a voltage.
Claims7
A shift device, comprising:
- a switching unit that controls operation of a motor that drives a speed change mechanism;
- a motor driver unit for driving the switching unit;
- a control unit that controls the motor driver unit;
- a motor power supply path that supplies electric power to the switching unit;
- a system power supply path that supplies electric power to the control unit;
- and
- a buck-boost unit that is provided in the system power supply path and that converts the electric power supplied from the system power supply path to a predetermined voltage and output the voltage, wherein
- electric power is supplied to the control unit via the buck-boost unit, and
- the electric power supplied to the motor driver unit is changed from the system power supply path to the motor power supply path based on a voltage.
