Abstract:
In a driving assist apparatus for assisting a lane change from an own lane to a target lane, when a post-smoothing probability obtained by smoothing a time course change in “a lane presence possibility which increases with the possibility that a target is another vehicle traveling in the target lane (target lane other vehicle)” is greater than a threshold value, that target can be extracted as the target lane other vehicle. The post-smoothing probability requires some length of time to coincide with the lane presence possibility. Therefore, if after completion of a lane change, another lane change is immediately started in the same direction, there arises a possibility that the target lane other vehicle cannot be extracted properly. Therefore, in the case where after completion of a lane change, another lane change is started in the same direction, the lane change is not started until a re-change prohibition time elapses.

Claim (Index 1):
A driving assist apparatus comprising:\n a target position obtainment section which detects at least one target present around an own vehicle and obtains a target position representing a position of said target in relation to said own vehicle; a probability obtainment section which obtains a target lane probability regarding said detected target in accordance with said target position, said target lane probability increasing with a possibility that said target is a target lane other vehicle which is another vehicle traveling in a target lane which is a lane located adjacent, in a specific direction which is a leftward or rightward direction, to a lane in which said own vehicle is traveling; a smoothing process section which obtains a post-smoothing probability regarding said detected target by smoothing a time course change in said target lane probability regarding said detected target; an other vehicle extraction section which extracts said target as said target lane other vehicle when said post-smoothing probability regarding said detected target is greater than a predetermined probability threshold; a control execution section which executes a lane change assist control for assisting a lane change to said target lane by controlling a turn angle of turnable wheels of said own vehicle when predetermined control start conditions are satisfied, the control start conditions including a determination that said own vehicle does not collide with said extracted target lane other vehicle during said lane change to said target lane; and a control prohibition section which prohibits execution of said lane change assist control for a new lane change to a lane adjacent to said target lane in said specific direction until a predetermined re-change prohibition time elapses after a predetermined specific condition is satisfied, the specific condition including entry of said own vehicle into said target lane.
