Lane change support system, lane change support device and lane change support method

摘要

To achieve a smooth lane change.SOLUTION: A lane change support system 1 includes: a first terminal 4-1 in a first vehicle 3-1; a second terminal 4-2 in a second vehicle 3-2; a third terminal 4-3 in a third vehicle 3-3; and a lane change support device 2. The lane change support device 2 is configured so that, when the first vehicle 3-1 running on a first running lane interrupts between the second vehicle 3-2 running on the second running lane next to the first running lane and the third vehicle 3-3 running in a line longitudinally and makes a lane change ahead of the third vehicle 3-3 running backward of the second vehicle 3-2, an economic value owned by a user of the first terminal 4-1 or the first vehicle 3-1 is reduced and an economic value owned by a user of the third terminal 4-3 or the third vehicle 3-3 is increased.SELECTED DRAWING: Figure 1
