Abstract
A controller for a switched reluctance motor, which includes a rotor, a stator, and coils wound around the stator and which is mounted on a vehicle as a traveling drive source, the controller including: a control unit performing regenerative control to apply a positive voltage and a negative voltage to the coils so that a current value of the coils becomes a first target current value in a predetermined regenerative region. Further, when the battery charge state value is a predetermined value or more, the control unit reduces a section where a negative voltage is applied to the coils to be narrower than that in a case where a battery charge state value is less than the predetermined value.
