Abstract: The present invention pertains to driving assistance method and device by which an automobile can be parked at a location near a target parking location when carrying out ACC. During deceleration control via ACC, when a predicted parking location is closer than a target parking location by at least a prescribed threshold value, a parking location is adjusted by causing a state change from a first state, in which deceleration control is carried out, to a second state, in which acceleration control is carried out.

Abstract: This driving support device outputs a target acceleration/deceleration for causing a host vehicle to track a preceding vehicle, if there is a preceding vehicle to track, and if there is no preceding vehicle to track, outputs a target acceleration for bringing the speed of the host vehicle to a set fixed speed, and modifies (corrects) the target acceleration in accordance with the lane width.

Abstract: This driving assistance device includes a target acceleration correcting unit configured as follows: if there was input, from a coupling detection unit, of detection results indicating that a trailer has been coupled, the target acceleration correcting unit outputs a target acceleration, output from an ACC unit, as-is to a drive system; and if there was input of detection results indicating that a trailer (2) has not been coupled, the target acceleration correcting unit corrects to a smaller value the target acceleration, output from the ACC unit, and outputs said corrected target acceleration to the drive system.
