  • Patent number: 11840232
    Abstract: A driving assistance device includes a lane change detection unit, a lane identification unit, a first space determination unit, an operation control unit. The lane identification unit identifies an original lane and a destination lane by using a detection result obtained by a boundary detection unit that detects a first boundary and a second boundary. The first boundary is a boundary between the original lane and the destination lane, and the second boundary is a boundary that defines the original lane and is located on a side opposite to the first boundary. When it is detected that the own vehicle is scheduled to perform a lane change and it is determined that the passable space is present, the operation control unit causes the own vehicle to perform a lateral movement operation before the lane change is performed. The lateral movement operation causes the own vehicle to approach the destination lane.
