Abstract
In a control device for a switched reluctance motor, a voltage drop control is executed in which a voltage dropped to be lower than a voltage applied in a case where the switched reluctance motor is driven in a high-load region is applied to the switched reluctance motor, in a case where the switched reluctance motor is driven in a low-load region. The low-load region is a lower load region than the high-load region.
Claims7
A control device for a switched reluctance motor, the control device comprising an electronic control unit configured to execute a voltage drop control in which a voltage dropped to be lower than a voltage applied in a case where the switched reluctance motor is driven in a high-load region is applied to the switched reluctance motor, in a case where the switched reluctance motor is driven in a low-load region, the low-load region being a lower load region than the high-load region, wherein
- the electronic control unit is further configured to turn on a first switch and turn off a second switch to control a voltage of a battery to a power supply state for supplying power to the switched reluctance motor;
- the electronic control unit is further configured to turn off the first switch and turn on the second switch to control the voltage of the battery to a non-power supply state in which the switched reluctance motor is not supplied with power;
- and
- the voltage is dropped based on a ratio of time in the power supply state and time in the non-power supply state.
