Abstract

A controller of a motor for a vehicle includes: a motor that has a plurality of rotors which respectively have a magnetic piece, and for which mutual relative phases are changeable, which drives or supplementarily drives a vehicle; a phase changing device that changes the relative phases of the plurality of rotors and performs adjustment to a predetermined induced voltage constant; a measuring device that measures an acceleration state quantity of the vehicle; and an induced voltage changing device that changes the induced voltage constant based on the acceleration state quantity measured by the measuring device.

Claims

1. A controller of a motor for a vehicle comprising:

a motor that has a plurality of rotors which respectively have a magnetic piece, and for which mutual relative phases are changeable, which drives or supplementarily drives a vehicle;

a phase changing device that changes the relative phases of said plurality of rotors and performs adjustment to a predetermined induced voltage constant;

a measuring device that measures an acceleration state quantity of said vehicle; and

an induced voltage changing device that changes said induced voltage constant based on said acceleration state quantity measured by said measuring device.

2. The controller of a motor for a vehicle according to claim 1, wherein

said phase changing device changes said induced voltage constant according to a magnitude of an average value of said acceleration state quantity within a fixed interval.

3. The controller of a motor for a vehicle according to claim 2, wherein

said phase changing device is provided with maps of induced voltage constants, in which a plurality have been set, and selects one map from within said plurality of maps according to a magnitude of an average value of the acceleration state quantity at a fixed interval.

4. The controller of a motor for a vehicle according to claim 2, further comprising a reporting device that reports driving preferences of a driver according to a magnitude of an average value of said acceleration state quantity at a fixed interval.

5. The controller of a motor for a vehicle according to claim 1, wherein

said phase changing device is provided with maps of induced voltage constants, in which a plurality have been set, and selects one map from within said plurality of maps according to a magnitude of an average value of the acceleration state quantity at a fixed interval.

6. The controller of a motor for a vehicle according to claim 5, further comprising a reporting device that reports driving preferences of a driver according to a magnitude of an average value of said acceleration state quantity at a fixed interval.

7. The controller of a motor for a vehicle according to claim 5, wherein

said phase changing device is provided with a manual operation device in which said maps are able to be manually changed and fixed.

8. The controller of a motor for a vehicle according to claim 1, further comprising a reporting device that reports driving preferences of a driver according to a magnitude of an average value of said acceleration state quantity at a fixed interval.
