Abstract
A vehicle control device including processor being configured to, when driving sections are present inside a restricted region, extract as a restricted driving section from among driving sections present inside the restricted region a driving section through which it is projected the vehicle will be driven in a restricted time period in which operation of internal combustion engines is restricted, and prepare a driving plan able to drive through the restricted driving section in the EV mode.
Claims20
A vehicle control device configured to control a vehicle equipped with an internal combustion engine, a rotating electric machine, and a battery, the vehicle control device comprising:
- a processor configured to:
- prepare a driving plan dividing a scheduled driving route up to a destination of the vehicle into a plurality of driving sections and setting which driving mode the driving sections should be driven in between an EV mode stopping the operation of the internal combustion engine and driving by the drive power of the rotating electric machine and an HV mode running by drive power of the internal combustion engine and the drive power of the rotating electric machine;
- and
- control the internal combustion engine and rotating electric machine based on the driving plan,
- wherein the processor is configured to:
- when driving sections are present inside a restricted region, extract as a restricted driving section from among driving sections present inside the restricted region a driving section through which it is projected the vehicle will be driven in a restricted time period in which operation of internal combustion engines is restricted,
- prepare the driving plan able to drive through the restricted driving section in the EV mode, and
- prepare the driving plan so that, if the destination is present inside the restricted region, the amount of electric power of the battery when arriving at the destination will not become less than the amount of electric power required for escaping from the destination to outside the restricted region.
A vehicle control device configured to control a vehicle equipped with an internal combustion engine, a rotating electric machine, and a battery, the vehicle control device comprising:

- and
- control the internal combustion engine and rotating electric machine based on the driving plan,
- wherein the processor is configured to:
- when driving sections are present inside a restricted region, extract as a restricted driving section from among driving sections present inside the restricted region a driving section through which it is projected the vehicle will be driven in a restricted time period in which operation of internal combustion engines is restricted;
- and
- prepare the driving plan able to drive through the restricted driving section in the EV mode, and
- prepare the driving plan so that, if the destination is present inside the restricted region, when it is scheduled to charge the battery at the destination, the amount of electric power of the battery at the time of start of the next trip starting from the destination does not fall below the amount of electric power required for escaping from the destination to outside of the restricted region.
A vehicle control method for controlling a vehicle equipped with an internal combustion engine, a rotating electric machine, and a battery, the vehicle control method comprising:
- a step of dividing a scheduled driving route up to a destination of the vehicle into a plurality of driving sections and setting which driving mode the driving sections should be driven in between an EV mode stopping the operation of the internal combustion engine and driving by the drive power of the rotating electric machine and an HV mode running by drive power of the internal combustion engine and the drive power of the rotating electric machine, wherein
- the step further includes:
- judging if driving sections are present inside a restricted region;
- when driving sections are present inside the restricted region, extracting as a restricted driving section from among driving sections present inside the restricted region a driving section through which it is projected the vehicle will be driven in a restricted time period in which operation of internal combustion engines is restricted;
- and
- setting the driving mode of the restricted driving section to the EV mode,
- preparing a driving plan so that, if the destination is present inside the restricted region, the amount of electric power of the battery when arriving at the destination will not become less than the amount of electric power required for escaping from the destination to outside the restricted region, and
- preparing the driving plan so that, if the destination is present inside the restricted region, when it is scheduled to charge the battery at the destination, the amount of electric power of the battery at the time of start of the next trip starting from the destination does not fall below the amount of electric power required for escaping from the destination to outside of the restricted region.
