Abstract
The present disclosure relates to a cooperative driving control technology, by which the set speed of an automatic cruise system of follower vehicles, other than a foremost vehicle, among cooperative driving vehicles is set to be higher by a certain value than the driving speed of the leader vehicle, and the headway time of a vehicle immediately after a departing vehicle is increased during a departure period of the follower vehicle, thereby enabling the departing vehicle to quickly and completely depart and preventing a collision between vehicles during the period.
Claims10
A cooperative driving control device that is a device for controlling vehicle cooperative driving of a cooperative driving group comprising a leader vehicle and at least one follower vehicle and is disposed in the leader vehicle, the device comprising:
- a set speed controller configured to generate a set speed indication message, which sets a set speed of an automatic cruise system of the follower vehicle comprised in the cooperative driving group to be higher by a first set value than a current driving speed of the leader vehicle, and to transmit the set speed indication message to the follower vehicle;
- and
- a departure controller configured to generate and transmit a headway time change request message, which sets a target headway time of a vehicle immediately after a departing vehicle to be longer than a default headway time for cooperative driving until departure is completed, when it is identified that one of the follower vehicle starts departing.
A cooperative driving control device that is a device for controlling vehicle cooperative driving of a cooperative driving group comprising a leader vehicle and at least one follower vehicle and is disposed in one of the follower vehicle, the device comprising:
- a set speed setter configured to set a set speed of an automatic cruise system to be higher by a first set value than a driving speed of the leader vehicle according to a set speed indication message when receiving the set speed indication message from the leader vehicle;
- and
- a headway time adjuster configured to set a target headway time to be longer than a default headway time for cooperative driving by a departure completion time of a departing vehicle that departs immediately ahead when receiving the headway time change request message from the leader vehicle.
A cooperative driving control method by a cooperative driving control device disposed in a leader vehicle in a cooperative driving system for controlling vehicle cooperative driving of a cooperative driving group comprising the leader vehicle and at least one follower vehicle, the method comprising:
- generating and transmitting, to the follower vehicle, a set speed indication message, which sets a set speed of an automatic cruise system of the follower vehicle comprised in the cooperative driving group to be higher by a first set value than a current driving speed of the leader vehicle;
- identifying that one of the follower vehicle starts departing;
- and
- generating and transmitting a headway time change request message, which sets a target headway time of a vehicle immediately after a departing vehicle to be longer than a default headway time for cooperative driving until departure of the departing follower vehicle is completed.
