Problems solved by technology

[0004] However, the behavior of the vehicle in situations other than avoiding obstacles is sometimes similar to the behavior of the vehicle in the case of avoiding obstacles, and there is a problem that it is wrongly determined that there is an obstacle when there is no obstacle
For example, the action when avoiding an obstacle to the left is similar to the action when turning left, so there may be cases where it is wrongly judged that there is an obstacle when it is clearly only turning left

Abstract

The present invention provides a technology capable of reducing the possibility of erroneously judging a left and right turning action as an obstacle avoidance action. The obstacle determination system includes: a reciprocating steering detection unit that detects reciprocating steering, which is a motion of the vehicle avoiding the obstacle; That is, when the steering start road and the steering end road, which is the road on which the vehicle exists at the end of the reciprocating steering, are the same road, it is determined that the reciprocating steering starts at the point where the reciprocating steering ends. The obstacle exists between the locations of the reciprocating steering maneuver.

Description

technical field [0001] The present invention relates to an obstacle judging system and an obstacle judging program. Background technique [0002] There is known a technique for determining whether the vehicle has encountered an obstacle based on the behavior of the vehicle (see Patent Document 1). In Patent Document 1, it is determined that the vehicle has encountered an obstacle when there is an urgent steering operation. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-234044 [0004] However, the behavior of the vehicle in situations other than avoiding an obstacle may be similar to the behavior of the vehicle when avoiding an obstacle, and there is a problem that an obstacle is erroneously determined to be present when there is no obstacle. For example, the action when avoiding an obstacle toward the left is similar to the action when turning left, so it may be wrongly determined that there is an obstacle when it is clearly only turning left.
