Driving Assistance Method and Driving Assistance Device

A driving assistance method comprising causing a controller to perform:

• processing of determining presence or absence of a parked vehicle ahead on a route of an own vehicle;
• processing of determining whether or not turning of the own vehicle is to be performed;
• processing of determining whether or not distance between a turning position at which the turning is performed and the parked vehicle satisfies a predetermined condition;
• trajectory generation processing of generating a target travel trajectory in such a way that, when the distance between the turning position and the parked vehicle satisfies the predetermined condition, the own vehicle passes beside the parked vehicle at a predetermined side position with a predetermined interval interposed between the parked vehicle and the own vehicle on one side of the parked vehicle and a turning end position in a case of turning at a position before a position of the parked vehicle or a turning start position in a case of turning after having passed beside the parked vehicle on the route coincides with the predetermined side position in a width direction of a road on which the parked vehicle is parked;
• and
• processing of performing travel control, based on the target travel trajectory.
