DRIVING ASSISTANCE METHOD AND DRIVING ASSISTANCE DEVICE

The present invention provides a driving assist method with which a lane change assist that does not conform to a driver's intention can be prevented. [0002] The present invention is a driving assist method performed by a recognition determination processor (3) that performs a lane change assist, which assists a lane change based on a generated target route, wherein upon determining that a lane change has been executed, determining whether or not the lane change is a lane change in a direction toward a preset location (S) due to a driver's operation. Next, upon determining that the lane change is a lane change in a direction toward the preset location (S) due to the driver's operation, determining whether or not a distance (L) from a host vehicle (V) to the preset location (S) is equal to or less than a first threshold value. When it has been assessed that the distance (L) from the host vehicle (V) to the preset location (S) is equal to or less than the first threshold value, an autonomous lane change in a direction away from the preset location (S) is restricted.
