Abstract
In the first mode, the vehicle gives priority to traveling in which only the motor is driven. In the second mode, the vehicle drives at least one of the internal combustion engine and the motor to sustain a stored power amount of the storage battery. At least one of a plurality of zones includes a load unknown portion, in which the travel load cannot be calculated. The planning unit is configured to set a zone including the load unknown portion to the first mode.
Claims5
An information processor for use with a vehicle, wherein the vehicle includes an internal combustion engine and a motor, which function as drive sources, and a storage battery, which functions as a power source of the motor, the information processor comprising:
- a travel route obtaining unit configured to obtain a travel route from a route origin to a route destination, wherein the travel route includes a plurality of zones;
- a zone information obtaining unit configured to obtain zone information used to calculate a travel load of each of the zones included in the travel route;
- and
- a planning unit configured to calculate the travel load of each of the zones, which are included in the travel route, using the zone information, wherein
- the planning unit is configured to set each zone to one of a first mode and a second mode based on the travel load,
- in the first mode, the vehicle gives priority to traveling in which only the motor is driven,
- in the second mode, the vehicle drives at least one of the internal combustion engine and the motor to sustain a stored power amount of the storage battery, and
- when at least one of the zones includes a load unknown portion in which the travel load cannot be calculated, the planning unit is configured to set the zone including the load unknown portion to the first mode.
A control method of a vehicle by an information processor for use with the vehicle, wherein the vehicle includes an internal combustion engine and a motor, which function as drive sources, and a storage battery, which functions as a power source of the motor, the control method comprising:
- obtaining a travel route from a route origin to a route destination, wherein the travel route includes a plurality of zones;
- obtaining zone information used to calculate a travel load of each of the zones included in the travel route;
- and
- calculating the travel load of each of the zones, which are included in the travel route, using the zone information;
- setting each zone to one of a first mode and a second mode based on the travel load;
- giving, in the first mode, priority to traveling in which only the motor is driven;
- driving, in the second mode, at least one of the internal combustion engine and the motor to sustain a stored power amount of the storage battery;
- and
- when at least one of the zones includes a load unknown portion in which the travel load cannot be calculated, setting the zone including the load unknown portion to the first mode.
