Abstract
In a motor drive mode of a hybrid vehicle where an engine is at a stop and the vehicle is driven with only the power from a motor, the motor is driven and controlled in a range up to a specific electric power, which is calculated by subtracting a starting electric power Ps required to start the engine from a maximum electric power Pmax output from a battery. At the time of starting the engine, the control stops the operations of auxiliary machinery, which is driven with the electric power from the battery, until completion of the start of the engine.
Claims20
A power output apparatus that is capable of outputting power from an internal combustion engine and power from a driving motor to a drive shaft, said power output apparatus comprising:
- a secondary battery that supplies electric power to said driving motor;
- a starting module that starts said internal combustion engine with a supply of electric power from said secondary battery;
- and
- a control module that drives and controls said driving motor to output a required power in a preset range of driving electric power to said drive shaft while said internal combustion engine is at a stop, where the range of driving electric power is set as a difference between a maximum electric power output from said secondary battery and a starting electric power required by said starting module to start said internal combustion engine.
An automobile that is driven with power from the internal combustion engine and power from the driving motor, which are output to the drive shaft linked with an axle, said automobile comprising:
- a secondary battery that supplies electric power to said driving motor;
- a starting module that starts said internal combustion engine with a supply of electric power from said secondary battery;
- and
- a control module that drives and controls said driving motor to output a required power in a preset range of driving electric power to said drive shaft while said internal combustion engine is at a stop, where the range of driving electric power is set as a difference between a maximum electric power output from said secondary battery and a starting electric power required by said starting module to start said internal combustion engine.
A control method of controlling a power output apparatus, which comprises an internal combustion engine that is capable of outputting power to a drive shaft, a driving motor that is capable of outputting power to said drive shaft, a secondary battery that supplies electric power to said driving motor, and a starting module that starts said internal combustion engine with a supply of electric power from said secondary battery,
- said control method comprising the steps of:
- driving and controlling said driving motor to output a required power in a preset range of driving electric power to said drive shaft while said internal combustion engine is at a stop, where the range of driving electric power is set as a difference between a maximum electric power output from said secondary battery and a starting electric power required by said starting module to start said internal combustion engine.
A control method of controlling a power output apparatus, which comprises an internal combustion engine that is capable of outputting power to a drive shaft, a driving motor that is capable of outputting power to said drive shaft, a secondary battery that supplies electric power to said driving motor, a starting module that starts said internal combustion engine with a supply of electric power from said secondary battery, and at least one auxiliary machinery that is driven with a supply of electric power from said secondary battery,
- said control method comprising the steps of:
- driving and controlling said driving motor to output a required power in a preset range of driving electric power to said drive shaft while said internal combustion engine is at a stop, where the range of driving electric power is set as a difference between a maximum electric power output from said secondary battery and a starting electric power required by said starting module to start said internal combustion engine,
- driving and controlling said at least one auxiliary machinery to stop its operation until completion of a start of said internal combustion engine, while controlling said starting module to start said internal combustion engine, in response to a starting requirement of said internal combustion engine that is at a stop.
A power output apparatus that is capable of outputting power from an internal combustion engine and power from a driving motor to a drive shaft, said power output apparatus comprising:
- chargeable dischargeable accumulator means for supplying electric power to said driving motor;
- starting means for starting said internal combustion engine with a supply of electric power from said secondary battery;
- and
- control means for driving and controlling said driving motor to output a required power in a preset range of driving electric power to said drive shaft while said internal combustion engine is at a stop, where the range of driving electric power is set as a difference between a maximum electric power output from said secondary battery and a starting electric power required by said starting module to start said internal combustion engine.
