Abstract

A driver can intuitively and conveniently perform an operation for instructing a traffic lane change to a vehicle. In a driving support device 10 , an image output unit 14 a outputs, to a display unit 31 , an image containing an own vehicle object representing an own vehicle and a plurality of traffic lanes. An operation signal input unit 14 b receives an operation of a user for moving the own vehicle object in the image displayed on the display unit 31 from a first traffic lane to a second traffic lane. A command output unit 14 c outputs, to an automatic driving control unit 20 that controls automatic driving, a command for instructing the change of a traveling traffic lane of the own vehicle from the first traffic lane to the second traffic lane when the operation is received.

First claim

The invention claimed is:

1. A driving support device comprising:
an image output unit which, in operation, outputs, to a display unit, an image containing a vehicle object representing a vehicle and a plurality of traffic lanes;
an operation signal input unit which, in operation, receives a first operation and a second operation of a user, wherein
the first operation moves the vehicle object in the image displayed on the display unit from a first traffic lane to a second traffic lane,
the image output unit, in response to the first operation being received by the operation signal input unit, outputs, to the display unit, an image containing a current vehicle object representing the vehicle in the first traffic lane and a target vehicle object representing the vehicle in the second traffic lane, and
the second operation moves the target vehicle object from the second traffic lane to the first traffic lane; and

a command output unit that outputs, to an automatic driving control unit that controls automatic driving, a first command for instructing a change of a traveling traffic lane of the vehicle from the first traffic lane to the second traffic lane in response to the first operation being received by the operation signal input unit, and a second command for canceling the first command in response to the second operation being received by the operation signal input unit within a predetermined time after the first operation being received by the operation signal input unit.

2. The driving support device of claim 1 wherein the image containing the current vehicle object and the target vehicle object includes a trajectory path from the first traffic lane to the second traffic lane.

3. A driving support system comprising:
a display device which, in operation, displays an image; and
a driving support device which, in operation, outputs the image on the display device,
wherein the driving support device includes:
an image output unit which, in operation, outputs, to the display device, an image containing a vehicle object representing a vehicle and a plurality of traffic lanes;
an operation signal input unit which, in operation, receives a first operation and a second operation of a user, wherein
the first operation moves the vehicle object in the image displayed on the display device from a first traffic lane to a second traffic lane,
the image output unit, in response to the first operation being received by the operation signal input unit, outputs, to the display device, an image containing a current vehicle object representing the vehicle in the first traffic lane and a target vehicle object representing the vehicle in the second traffic lane, and
the second operation moves the target vehicle object from the second traffic lane to the first traffic lane; and
a command output unit that outputs, to an automatic driving control unit that controls automatic driving, a first command for instructing a change of a traveling traffic lane of the vehicle from the first traffic lane to the second traffic lane in response to the operation being received by the operation signal input unit, and a second command for canceling the first command in response to the second operation being received by the operation signal input unit within a predetermined time after the first operation being received by the operation signal input unit.

4. The driving support system of claim 3 wherein the image containing the current vehicle object and the target vehicle object includes a trajectory path from the first traffic lane to the second traffic lane.

5. A driving support method comprising:
outputting, to a display unit, an image containing a vehicle object representing a vehicle and a plurality of traffic lanes;
receiving a first operation of a user for moving the vehicle object in the image displayed on the display unit from a first traffic lane to a second traffic lane;
outputting, in response to the first operation being received, to the display unit, an image containing a current vehicle object representing the vehicle in the first traffic lane and a target vehicle object representing the vehicle in the second traffic lane;
outputting, in response to the first operation being received, to an automatic driving control unit that controls automatic driving, a first command for instructing a change of a traveling traffic lane of the vehicle from the first traffic lane to the second traffic lane;
receiving a second operation of the user for moving the target vehicle object from the second traffic lane to the first traffic lane; and
outputting, in response to the second operation being received within a predetermined time after the first operation being received, to the automatic driving control unit, a second command for canceling the first command.

6. The driving support method of claim 5 wherein the image containing the current vehicle object and the target vehicle object includes a trajectory path from the first traffic land to the second traffic lane.
