Abstract

A mobility information processing apparatus includes: an allocator that allocates one driving mode-selected from driving modes having different drive forms to each partitioned section, in a route of a moving object; and an estimator that estimates the driving mode selected for each section located apart from a predetermined point in the route and that calculates an estimated amount of energy required for traveling in the section estimated to correspond to the one selected driving mode among the driving modes, wherein the allocator determines whether the one selected driving mode is allocated to each section up to a predetermined point in the route on the basis of an allocated energy amount obtained by subtracting the estimated energy amount calculated by the estimator from a residual energy amount of a power source used in the one selected driving mode for each section up to the predetermined point in the route.

First claim

1 . A mobility information processing apparatus comprising:
a first electronic control unit configured to allocate one driving mode, which is selected from a plurality of driving modes having different drive forms, as the driving mode of a moving object to each partitioned section in a travel route of the moving object; and a second electronic control unit configured to estimate the driving mode selected for each section located apart from a predetermined point in the travel route and calculate an estimated amount of energy required for traveling in the section estimated to correspond to the one selected driving mode among the plurality of driving modes, wherein the first electronic control unit determines whether the one selected driving mode is allocated to each section up to a predetermined point in the travel route on the basis of an allocated amount of energy obtained by subtracting the estimated amount of energy calculated by the second electronic control unit from a residual amount of energy of a power source used in the one selected driving mode for each section up to the predetermined point in the travel route.

2 . The mobility information processing apparatus according to claim 1 , wherein
the predetermined point in the travel route is a point determined as the upper limit value of the number of sections in the travel route to which the driving modes are able to be allocated by the first electronic control unit.

3 . The mobility information processing apparatus according to claim 1 , wherein
the moving object is a hybrid vehicle, and the plurality of driving modes includes a mode in which the hybrid vehicle travels by the use of an electric motor using a battery as a power source as the one selected driving mode and includes a second driving mode which is a driving mode in which the hybrid vehicle travels by the use of the electric motor and an internal combustion engine together when the one selected driving mode is a first driving mode.

4 . The mobility information processing apparatus according to claim 3 , wherein
a travel load used to calculate an energy balance required for traveling in each section of the travel route is set for each section, and the first electronic control unit allocates the first driving mode to the sections having a relatively low travel load among the sections up to the predetermined point in the travel route and allocates the second driving mode to the other sections.

5 . The mobility information processing apparatus according to claim 4 , wherein
the first electronic control unit allocates the first driving mode to the sections in the travel route in the ascending order of the travel load.

6 . The mobility information processing apparatus according to claim 4 , wherein
the second electronic control unit estimates sections to which the first driving mode is allocated on the basis of the travel load.

7 . The mobility information processing apparatus according to claim 1 , wherein
the second electronic control unit merges the sections estimated to correspond to the one selected driving mode into one section and calculates the estimated amount of energy of the merged section, and the first electronic control unit calculates the allocated amount of energy by subtracting the estimated amount of energy of the merged section from the residual amount of energy of a power source used in the one selected driving mode for each section up to the predetermined point in the travel route.

8 . The mobility information processing apparatus according to claim 1 , wherein
the second electronic control unit further estimates the amount of energy required for all the sections of the travel route, and the first electronic control unit allocates the one selected driving mode to all the sections of the travel route when the residual amount of energy of the power source used in the one selected driving mode is greater than the estimated amount of energy required for all the sections of the travel route in the sections up to the predetermined point in the travel route before determining whether the one selected driving mode is allocated to the sections up to the predetermined point in the travel route.

9 . The mobility information processing apparatus according to claim 1 , wherein
the first electronic control unit is disposed in the moving object.

10 . A mobility information processing method of allocating one driving mode, which is selected from a plurality of driving modes having different drive forms, as the driving mode of a moving object to each partitioned section in a travel route of the moving object, comprising:
estimating the driving mode selected for each section located apart from a predetermined point in the travel route and calculating an estimated amount of energy required for traveling in the section estimated to correspond to the one selected driving mode among the plurality of driving modes; and determining whether the one selected driving mode is allocated to each section up to a predetermined point in the travel route on the basis of an allocated amount of energy obtained by subtracting the calculated estimated amount of energy from a residual amount of energy of a power source used in the one selected driving mode for each section up to the predetermined point in the travel route.

11 . A mobility information processing apparatus comprising:
a first electronic control unit configured to allocate one driving mode, which is selected from a plurality of driving modes having different drive forms, as the driving mode of a moving object to each partitioned section in a travel route of the moving object and allocate one driving mode, which is selected from the plurality of driving modes on the basis of an attribute condition determined depending on a section attribute of each section up to a predetermined point in the travel route, as the driving mode of the sections up to the predetermined point in the travel route when an amount of energy required for traveling in the sections located apart from the predetermined point in the travel route is not able to be estimated.

12 . The mobility information processing apparatus according to claim 11 , wherein
the predetermined point in the travel route is a point determined as the upper limit value of the number of sections in the travel route to which the driving modes are able to be allocated by the first electronic control unit.

13 . The mobility information processing apparatus according to claim 11 , wherein
the moving object is a hybrid vehicle, the plurality of driving modes includes a mode in which the hybrid vehicle travels by the use of an electric motor using a battery as a power source as the one selected driving mode and includes a second driving mode which is a driving mode in which the hybrid vehicle travels by the use of the electric motor and an internal combustion engine together when the one selected driving mode is a first driving mode, and the attribute condition determined depending on the section attribute is a condition determined depending on a type of a road on which the hybrid vehicle travels.

14 . The mobility information processing apparatus according to claim 13 , wherein
the type of a road includes a roadway and an expressway, and the first electronic control unit allocates the first driving mode to the roadway and allocates the second driving mode to the expressway.

15 . A mobility information processing method of allocating one driving mode, which is selected from a plurality of driving modes having different drive forms, as the driving mode of a moving object to each part
