Abstract

A communication control device controls communication of an in-vehicle communication device which is communicable with a mobile communication device. The communication control device includes a processor including hardware, the processor being configured to: create or acquire a travel plan of a vehicle equipped with the in-vehicle communication device; and create a communication plan to switch at least one of a communication amount and a communication frequency between the in-vehicle communication device and the mobile communication device at switching time of a travel state of the travel plan according to a mode change of the travel state.

Claims

1. A communication control device for controlling communication of an in-vehicle communication device which is communicable with a mobile communication device, the communication control device comprising:

a processor comprising hardware, the processor being configured to;

create or acquire a travel plan of a vehicle equipped with the in-vehicle communication device; and

create a communication plan to switch at least one of a communication amount and a communication frequency between the in-vehicle communication device and the mobile communication device at switching time of a travel state of the travel plan according to a mode change of the travel state.

2. The communication control device according to claim 1, wherein

the vehicle is a hybrid type vehicle including an engine, a chargeable and dischargeable in-vehicle battery, and a rotating electric machine driven by power of the vehicle battery,

the processor is further configured to create the travel plan by setting either an EV mode in which the power of the in-vehicle battery is used as a main power source or an HV mode in which the engine is used as the main power source as a travel mode to be used depending on a travel section, and

the switching time is switch time of the set travel mode.

3. The communication control device according to claim 2, wherein the processor is configured to:

set one or more transit points on a predicted route from a departure point to a destination point;

divide the predicted route into a plurality of travel routes divided by the transit points;

further divide each of the travel route into a plurality of travel sections; and

set the travel mode of all of the travel sections in at least one travel route to the EV mode.

4. The communication control device according to claim 3, wherein the processor is configured to:

calculate a route power consumption which is an estimated power consumed when each of the travel routes is traveled in the EV mode;

set the travel mode of the travel sections in the travel route to the EV mode in order from the travel route having a small route power consumption, and

create a route travel plan by setting the travel mode of all the travel sections in the travel route to the HV mode in and after the travel route in which an accumulated value obtained by adding the route power consumption of the travel routes in order from the travel route having a small route power consumption exceeds an available power of the in-vehicle battery.

5. The communication control device according to claim 1, wherein the switching time is switch time of engine control according to a predicted travel load.

6. The communication control device according to claim 1, wherein the switching time is changing time of a predicted road condition.

7. The communication control device according to claim 1, wherein the processor is configured to recreate and update the travel plan according to the travel of the vehicle.

8. The communication control device according to claim 1, wherein the communication control device is mounted on the mobile communication device.

9. The communication control device according to claim 1, wherein the communication control device is communicable with the mobile communication device and configured to transmit the created travel plan to the mobile communication device.

10. The communication control device according to claim 1 wherein the communication plan is a plan of at least one of the communication amount and the communication frequency for communicating data related to vehicle information of the vehicle from the in-vehicle communication device to the mobile communication device.

11. A communication system, comprising:

an in-vehicle communication device provided in a vehicle;

a mobile communication device capable of data communication with the in-vehicle communication device;

a server configured to control the mobile communication device via a communication network;

a processor configured to;

create or acquire a travel plan of the vehicle equipped with the in-vehicle communication device; and

create a communication plan to switch at least one of a communication amount and a communication frequency between the in-vehicle communication device and the mobile communication device at switching time of a travel state of the travel plan according to a mode change of the travel state.

12. A method of controlling communication of an in-vehicle communication device communicable with a mobile communication device, the method comprising:

creating or acquiring a travel plan of a vehicle equipped with the in-vehicle communication device, and storing the travel plan in a storage unit; and

creating a communication plan to switch at least one of a communication amount and a communication frequency between the in-vehicle communication device and the mobile communication device at switching time of a travel state of the travel plan according to a mode change of the travel state.
