Patent number: 10780884Abstract: A cruise control apparatus controls the traveling of an own vehicle on the basis of the predicted route which is a predicted value of the travel route of an own vehicle. The cruise control apparatus compares the moving locus of the preceding vehicle with the position of a stationary object provided along the road to determine whether or not a moving locus is along the shape of the road. The moving locus is validated when it is determined that the moving locus is along the shape of the road, and the moving locus is invalidated when it is determined that the moving locus is not along the shape of the road, and the predicted route of the vehicle is calculated on the basis of the validated moving locus.Type: GrantFiled: November 16, 2015Date of Patent: September 22, 2020Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Youhei Masui, Toyoharu Katsukura, Yoshihisa Ogata, Takeshi Nanami, Takashi Nishida
