Abstract

An apparatus includes an unit that plans any driving mode of an EV mode in which the motor is used as the drive source and an HV mode in which at least the engine is used as the drive source for each section, into which a route from the current location to the destination is partitioned, when a load for running in each section is set. The setup unit plans the mode using an aspect in which the HV mode is preferentially planned for a section including at least one of a current section including the current location and a section after the current section when a remaining amount of the battery is lower than a threshold of the remaining amount of the battery, and regenerative energy obtained from running load information is higher than or equal to a value determining a restoration of the remaining amount of the battery.

Claims

1. A movement support apparatus that supports movement of a vehicle having an internal combustion engine and a motor as drive sources from a current location to a destination, comprising

a processor programmed to set up any driving mode of an EV mode in which the motor using a battery is used as the drive source and an HV mode in which at least the internal combustion engine is used as the drive source for each section, into which a driving route from the current location to the destination is partitioned, when a running load for running in each section is set, the processor setting up the driving mode using an aspect in which the HV mode is preferentially set up for a section including at least any one of a current section including the current location and a section after the current section when a remaining amount of the battery is lower than a remaining amount threshold value which is a determination value of the remaining amount of the battery, and regenerative energy obtained from information of the running load is higher than or equal to a regenerative threshold value which is a determination value for restoration from the remaining amount of the battery.

2. The movement support apparatus according to claim 1, wherein

the processor is programmed to perform setup of the driving mode under a condition in which a distance to the destination is longer than or equal to a predetermined distance.

3. The movement support apparatus according to claim 1, wherein

the processor is programmed to add up the energy consumption in sequence from each of the sections closer to the current location on the driving route, a virtual running load which is higher than the running load of each of the sections is set in a section in which the total energy consumption is higher than a predetermined threshold value, the EV mode is set up for the driving mode of a section in which the running load including the virtual running load is relatively low among each of the sections on the driving route, and the HV mode is set up for the driving mode of other sections.

4. The movement support apparatus according to claim 3, wherein

the processor is programmed to set the virtual running load to be low in sequence from sections closer to the current location on the driving route.

5. A movement support method which supports a movement from a current location to a destination of a vehicle including an internal combustion engine and a motor as a driving source, comprising:

setting up any one driving mode of an EV mode including the motor using a battery as the driving source and an HV mode including at least the internal combustion engine as the driving source for each section while setting a running load at the time of travelling in each of the sections in the EV mode as the driving mode, in each of the sections into which a driving route from the current location to the destination is divided; and

setting up the driving mode using an aspect in which the HV mode is preferentially set up for a section including at least any one of a current section including the current location and a section after the current section when a remaining amount of the battery is lower than a remaining amount threshold value which is a determination value of the remaining amount of the battery, and regenerative energy obtained from information of the running load is higher than or equal to a regenerative threshold value which is a determination value of a restoration of the remaining amount of the battery.

6. The movement support method according to claim 5, wherein

the driving mode is set up under a condition in which a distance to the destination is longer than or equal to a predetermined distance.

7. A movement support apparatus that supports a movement from a current location to a destination of a vehicle including an internal combustion engine and a motor as a driving source, comprising

a processor programmed to set up any one driving mode of an EV mode including the motor using a battery as the driving source and an HV mode including at least the internal combustion engine as the driving source for each section while setting a running load at the time of travelling in each of the sections in the EV mode as the driving mode, in each of the sections into which a driving route from the current location to the destination is divided, the processor setting up the driving mode using an aspect in which the HV mode is preferentially set up for a section before a section in which regenerative energy is obtained when a remaining amount of the battery is lower than a remaining amount threshold value which is a determination value of the remaining amount of the battery, and the regenerative energy obtained from information of the running load is higher than or equal to a regenerative threshold value which is a determination value of a restoration of the remaining amount of the battery.

8. A movement support method that supports a movement from a current location to a destination of a vehicle including an internal combustion engine and a motor as a driving source, comprising:

setting up any one driving mode of an EV mode including the motor using a battery as the driving source and an HV mode including at least the internal combustion engine as the driving source for each section while setting a running load at the time of travelling in each of the sections in the EV mode as the driving mode, in each of the sections into which a driving route from the current location to the destination is divided; and

9. A driving support system that supports driving of a vehicle on the basis of one driving mode selected from a plurality of different driving modes set up for each section into which a driving route from a current location to a destination of the vehicle including an internal combustion engine and a motor as a driving source is divided, comprising
