Title:
衝突推定装置および衝突推定方法
Document Type and Number:
Japanese Patent JP6690604
Kind Code:
B2
Abstract:
A collision estimation device (10) comprises a vehicle trajectory estimation unit (11), a moving object trajectory estimation unit (12), a shielding object specification unit (13), a moving object extraction region setting unit (14), a direction change information acquisition unit (15), and a collision estimation unit (16). When a moving object is recognized within a moving object extraction region, and a change in the advancement direction indicated by direction change information is not in a direction moving away from a shielding object, the collision estimation unit estimates the existence of a collision using an estimated trajectory of the moving object on the basis of information obtained from a first sensor in a shorter time than when a moving object is recognized in a region differing from the moving object extraction region. When the change in the advancement direction is a direction moving away from the shielding object, the collision estimation unit estimates the existence of a collision using an estimated trajectory of the moving object on the basis of information obtained from the first sensor in the same amount of time or a longer time.
