Abstract

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 includes: a setup unit that sets up any driving mode of an EV mode and an HV mode 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; and a change unit that changes the driving mode in a part of each section of the driving route to a driving mode other than the driving mode set up by the setup unit on: the basis of at least one of a running environment including a running state of the vehicle and a road environment and the miming load as consumption of the battery necessary for running in the EV mode.

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 setup unit that sets 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; and

a change unit that changes the driving mode in a part of each section of the driving route to a driving mode other than the driving mode set up by the setup unit based on at least one of a running environment including a running state of the vehicle and a road environment and the running load as consumption of the battery necessary for running in the EV mode,

wherein the change unit changes the driving mode of the section, for which the EV mode is set up, to the HV mode on a condition that the vehicle is decelerated and then accelerated in the section, for which the EV mode is setup.

2. The movement support apparatus according to claim 1, wherein the change unit changes the driving mode of the section, for which the EV mode is set up, to the HV mode on a condition that a remaining distance in the section, for which the EV mode is setup, up to a next section is less than a predetermined distance.

3. The movement support apparatus according to claim 1, wherein the change unit changes the driving mode of the section, for which the EV mode is set up, to the HV mode on a condition that the HV mode is set up for the section next to the section, for which the EV mode is setup.

4. The movement support apparatus according to claim 1, wherein the change unit changes the driving mode of the section in which regenerative energy is obtained from the HV mode to the EV mode when the regenerative energy is obtained at a time of entry from the section for which the EV mode is set up by the setup unit into the section for which the HV mode is set up.

5. The movement support apparatus according to claim 1, wherein the change unit re-changes the driving mode of the section, for which the HV mode is set up, to the HV mode when at least one condition of a condition that a predetermined time elapses after the driving mode of the section for which the HV mode is set up is changed to the EV mode and a condition that the vehicle runs a predetermined distance thereafter is satisfied.

6. The movement support apparatus according to claim 1, wherein determination of whether to change the driving mode by the change unit is performed in a cycle shorter than a setup cycle by the setup unit after the driving mode of the vehicle is set up by the setup unit.

8. A driving support system that supports driving of a vehicle having an internal combustion engine and a motor as drive sources based on one driving mode selected from a plurality of driving modes different from each other, which is set up for sections into which a driving route of the vehicle is partitioned from a current location to a destination, comprising:

the movement support apparatus according to claim 1 that sets up one driving mode selected from the plurality of driving modes for each section of the driving route and changes the driving mode if necessary.

7. A movement support method of supporting movement of a vehicle having an internal combustion engine and a motor as drive sources from a current location to a destination, comprising:

setting 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;

changing the driving mode in a part of each section of the driving route to a driving mode other than the set-up driving mode based on at least one of a running environment including a running state of the vehicle and a road environment and the running load as consumption of the battery necessary for running in the EV mode; and

changing the driving mode of the section, for which the EV mode is set up, to the HV mode on a condition that the vehicle is decelerated and then accelerated in the section, for which the EV mode is setup.

9. 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 setup unit that sets 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; and

a change unit that changes the driving mode in a part of each section of the driving route to a driving mode other than the driving mode set up by the setup unit based on at least one of a running environment including a running state of the vehicle and a road environment and the running load as consumption of the battery necessary for running in the EV mode,

wherein the change unit changes the driving mode of the section in which regenerative energy is obtained from the HV mode to the EV mode when the regenerative energy is obtained at a time of entry from the section for which the EV mode is set up by the setup unit into the section for which the HV mode is set up.

10. The movement support apparatus according to claim 9, wherein the change unit re-changes the driving mode of the section, for which the HV mode is set up, to the HV mode when at least one condition of a condition that a predetermined time elapses after the driving mode of the section for which the HV mode is set up is changed to the EV mode and a condition that the vehicle runs a predetermined distance thereafter is satisfied.

11. The movement support apparatus according to claim 9, wherein determination of whether to change the driving mode by the change unit is performed in a cycle shorter than a setup cycle by the setup unit after the driving mode of the vehicle is set up by the setup unit.
