Abstract
A hybrid vehicle drive apparatus including an electric power generator mechanically connected to the engine, a drive motor driven by at least one of an electric current generated by the electric power generator and an electric current supplied from a battery; a detector that detects a battery state of the battery and a controller that sets a target torque of the drive motor based on the battery state.
Claims25
A hybrid vehicle drive control apparatus, comprising:
- an electric power generator mechanically connected to an engine;
- a drive motor driven by at least one of an electric current generated by the electric power generator and an electric current supplied from a battery;
- a detector that detects a battery state of the battery;
- and
- a controller that:
- calculates a lowest limit value of the battery state based on a rotating state of the electric power generator;
- and
- sets a target torque of the drive motor based on the lowest limit value of the battery state.
A control method of a hybrid vehicle drive apparatus, comprising:
- generating an electric current by an electric power generator mechanically connected to an engine;
- driving a drive motor by at least one of the electric current generated by the electric power generator and an electric current supplied from a battery;
- detecting a battery state of the battery;
- calculating a lowest limit value of the battery state based on a rotating state of the electric power generator;
- and
- setting a target torque of the drive motor based on the lowest limit value of the battery state.
A computer readable memory medium for a hybrid vehicle drive apparatus including an electric power generator mechanically connected to an engine, a drive motor driven by at least one of an electric current generated by the electric power generator and an electric current supplied from a battery, and a detector that detects a battery state of the battery, the memory medium storing a program comprising:
- instructions to calculate a lowest limit value of the battery state based on a rotating state of the electric power generator;
- and
- instructions to set a target torque of the drive motor based on the lowest limit value of the battery state.
