Driving control device, driving control method and vehicle-to-vehicle communication system
First Claim
1. A driving control device for controlling driving of a vehicle, the driving control device comprising:
- a sensor unit that detects a circumferential vehicle of an own-vehicle;
a vehicle-mounted communication device that mutually transmits and receives information including an identification number and position information with a vehicle-mounted communication device mounted on the circumferential vehicle of the own-vehicle and maintains the information as a table;
a travel determination unit that determines a travel control of the own-vehicle based on a detection result of the sensor unit and the table maintained by the vehicle-mounted communication device; and
a travel control unit that controls traveling of the own-vehicle based on a result obtained by a determination made by the travel determination unit, wherein;
when the own-vehicle changes a lane, the travel determination unit identifies a following traveling vehicle on a change destination lane based on a detection result of the sensor unit and selects an identification number of the following traveling vehicle from the table maintained by the vehicle-mounted communication device, and the vehicle-mounted communication device uses the identification number and transmits, to the following traveling vehicle, information on a lane change request by unicast.

Abstract
Provided are a driving control method and device in which an actual driving operation is performed after vehicles communicate with each other regarding a safety check by vehicle-to-vehicle communication in advance, thereby making it possible to smoothly and safely change lanes or merge when a vehicle is changing lanes or merging by automatic driving. The driving control device is provided with: a sensor unit that detects vehicles around a vehicle; a vehicle-mounted communication device that transmits and receives information including an identification number and position information to/from vehicle-mounted communication devices that are mounted to the vehicles around the vehicle and maintains said information as a table; a travel determination unit for determining travel control for the vehicle on the basis of the detection result of the sensor unit and the table maintained by the vehicle-mounted communication device; and a travel control unit that controls the travel of the vehicle on the basis of the result determined by the travel determination unit. The driving control device is characterized in that when the vehicle is changing lanes, the travel determination unit identifies a following linearly traveling vehicle in the lane that is the lane change destination from the detection result of the sensor unit and selects the identification number of the following linearly traveling vehicle from the table maintained by the vehicle-mounted communication device, and the vehicle-mounted communication device uses the identification number to transmit information requesting a lane change to the following linearly traveling vehicle in unicast format.

6. A driving control method for controlling driving of a vehicle when a lane is changed, the driving control method comprising:
-
identifying a following traveling vehicle on a change destination lane through a sensor unit mounted on an own-vehicle; transmitting and receiving information including an identification number and position information between a vehicle-mounted communication device mounted on the own-vehicle and a vehicle-mounted communication device mounted on a circumferential vehicle of the own-vehicle and maintaining the information as a table; selecting the identification number of the following traveling vehicle from the table maintained by the vehicle-mounted communication device and transmitting information on a lane change request, to the following traveling vehicle using the identification number by unicast; and performing a lane change after the vehicle-mounted communication device receives, from the following traveling vehicle, a reply to acknowledge the lane change by unicast. - View Dependent Claims (7)

10. A record medium recording a drive control program for controlling driving a vehicle when a lane is changed, the record medium causing a computer to execute the processes of:
-
identifying a following traveling vehicle on a change destination lane by a sensor unit mounted on an own-vehicle; mutually transmitting and receiving information including an identification number and position information between a vehicle-mounted communication device mounted on the own-vehicle and a vehicle-mounted communication device mounted on a circumferential vehicle of the own-vehicle and maintaining the information as a table; selecting the identification number of the following traveling vehicle from the table maintained by the vehicle-mounted communication device and transmitting, to the following traveling vehicle, information on a lane change request using the identification number by unicast; and performing a lane change after the vehicle-mounted communication device receives, from the following traveling vehicle, a reply to acknowledge the lane change by unicast.
