Abstract

A driving assistance method for proposing and making a lane change by autonomous travel control, based on an approval action taken by a passenger, causes a controller to: when detecting a preceding vehicle traveling at a speed lower than a vehicle speed of an own vehicle, a first distance being the distance between another vehicle in a first adjacent lane and the own vehicle, is determined to be greater than or equal to a first threshold value, start to propose a lane change to the first adjacent lane; when the first distance is greater than or equal to a second threshold value smaller than the first threshold value, continue proposing a lane change to the first adjacent lane; and when while proposing a lane change to the first adjacent lane, an approval action is taken by the passenger, cause a turn signal on a first adjacent lane side to operate.
