Abstract

An automatic driving control device mounted in an automatic driving vehicle for executing automatic driving along a planned travelling route includes: a driving execution unit that executes driving of the automatic driving vehicle; a communication unit that communicates with outside of the automatic driving vehicle; and a control unit that executes the automatic driving by controlling the driving execution unit. The communication unit has a first receiving unit that receives instruction signals for instructing driving contents of the automatic driving vehicle. The control unit has a first determination unit that determines provisional driving contents which are the driving contents of the automatic driving vehicle according to the instruction signals, when the instruction signals are received during execution of the automatic driving, and the control unit executes the automatic driving using the determined provisional driving contents.

First claim

What is claimed is:

1 . An automatic driving control device mounted in an automatic driving vehicle for executing automatic driving along a planned travel route, the comprising:
a driving execution unit that executes driving of the automatic driving vehicle; a communication unit that communicates with outside of the automatic driving vehicle; and a control unit that executes the automatic driving by controlling the driving execution unit, wherein the communication unit has a first receiving unit that receives instruction signals for instructing driving contents of the automatic driving vehicle, the control unit has a first determination unit that determines provisional driving contents which are the driving contents of the automatic driving vehicle according to the instruction signals, when the instruction signals are received during execution of the automatic driving, the control unit executes the automatic driving using the determined provisional driving contents, and wherein the communication unit further has: a first transmission unit that transmits first content signals indicating the driving contents indicated by the instruction signals and the provisional driving contents to any other automatic driving vehicle; and a second receiving unit that receives, from the other automatic driving vehicle, second content signals indicating the driving contents to be executed by the other automatic driving vehicle upon reception of the first content signals, wherein the control unit further has a second determination unit that determines conclusive driving contents which are the driving contents of the automatic driving vehicle according to the driving contents indicated by the second content signals received by the second receiving unit and the driving contents indicated by the instruction signals, and the control unit executes the automatic driving based on the conclusive driving contents.

2 . The automatic driving control device according to claim 1 ,
wherein the driving contents of the automatic driving include traveling of the automatic driving vehicle in the front, rear, right and left directions.

3 . The automatic driving control device according to claim 1 ,
wherein the control unit, when receiving a plurality of the instruction signals during execution of the automatic driving, executes the automatic driving using the provisional driving contents determined according to the instruction signals, in accordance with preset priority, in descending order of the priority.

4 . The automatic driving control device according to claim 1 ,
wherein the control unit communicates with the other automatic driving vehicle which has received the first content signals via the communication unit to execute the automatic driving based on the conclusive driving contents in sync with the execution of the automatic driving of the other automatic driving vehicle upon reception of the first content signals.

5 . The automatic driving control device according to claim 4 ,
wherein, when the driving contents to be executed by the automatic driving vehicle are traveling in either one of the right and left directions, the driving contents to be executed by the other automatic driving vehicle are traveling in the other of the right and left directions, which is different from that of the automatic driving vehicle, and the control unit executes the automatic driving of the automatic driving vehicle in sync with the execution of the automatic driving of the other automatic driving vehicle, in the case where the other automatic driving vehicle is present within a range set on the basis of the automatic driving vehicle as a reference, the control unit adjusts the position of the automatic driving vehicle relative to the other automatic driving vehicle so that the other automatic driving vehicle is positioned outside the range.

6 . The automatic driving control device according to claim 4 ,
wherein the communication unit further has a second transmission unit that transmits a preset signal to the other automatic driving vehicle, and wherein the control unit allows the second transmission unit to transmit the preset signal, and then executes the automatic driving based on the conclusive driving contents.

7 . The automatic driving control device according to claim 1 ,
wherein the control unit further has an information acquisition unit that communicates with the other automatic driving vehicle to acquire identification information on the other automatic driving vehicle, and wherein the first transmission unit, when transmitting the first content signals, transmits the first content signals together with the preliminarily acquired identification information on the other automatic driving vehicle.

8 . The automatic driving control device according to claim 1 ,
wherein the communication unit further has: a first transmission unit that transmits first content signals indicating the driving contents indicated by the instruction signals and the provisional driving contents to any other automatic driving vehicle; and wherein, when the control unit executes the automatic driving based on the provisional driving contents, the provisional driving contents to be executed by the automatic driving vehicle are traveling in either one of the right and left directions upon reception of the first content signals, the driving contents to be executed by the other automatic driving vehicle are traveling in the other of the right and left directions, which is different from that of the automatic driving vehicle, and the automatic driving vehicle and the other automatic driving vehicle each execute the automatic driving, in the case where the other automatic driving vehicle is present within a range set on the basis of the automatic driving vehicle as a reference, the control unit adjusts the position of the automatic driving vehicle relative to the other automatic driving vehicle so that the other automatic driving vehicle is positioned outside the range.

9 . An automatic driving control device mounted in an automatic driving vehicle for executing automatic driving along a planned travel route, the comprising:
a driving execution unit that executes driving of the automatic driving vehicle; a communication unit that communicates with outside of the automatic driving vehicle; and a control unit that executes the automatic driving by controlling the driving execution unit, wherein the communication unit has a first receiving unit that receives instruction signals for instructing driving contents of the automatic driving vehicle, wherein the control unit has a first determination unit that determines provisional driving contents which are the driving contents of the automatic driving vehicle according to the instruction signals, when the instruction signals are received during execution of the automatic driving, wherein the control unit executes the automatic driving using the determined provisional driving contents, wherein the communication unit further has: a first transmission unit that transmits first content signals indicating the driving contents indicated by the instruction signals and the provisional driving contents to any other automatic driving vehicle; and wherein, when the control unit executes the automatic driving based on the provisional driving contents, the provisional driving contents to be executed by the automatic driving vehicle are traveling in either one of the right and left directions upon reception of the first content signals, the driving contents to be executed by the other automatic driving vehicle are traveling in the other of the right and left directions, which is different from that of the automatic driving veh
