Patent number: 11364901Abstract: A driving support apparatus according to the invention estimates the position of a moving body by controlling a position estimation unit when the tracking-target moving body leaves a first area or a second area to enter a blind spot area and detects the position of the moving body by controlling a position detection unit when the moving body leaves the blind spot area to enter the first area or the second area. In this manner, the trajectory of the tracking-target moving body is calculated so that the trajectory of the moving body detected in the first area or the second area and the trajectory of the moving body estimated in the blind spot area are continuous to each other and driving support is executed based on the calculated trajectory of the tracking-target moving body.Type: GrantFiled: May 22, 2020Date of Patent: June 21, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Quy Hung Nguyen Van, Shoichi Hayasaka

Vehicle driving situation determination apparatus and vehicle driving situation determination method
Patent number: 9975548Abstract: A vehicle driving situation determination apparatus includes an object detector for detecting an object around a vehicle and an electronic control unit (ECU). The ECU calculates an index relating to a traveling state of the vehicle, wherein the index is a value that is obtained by dividing a jerk of the vehicle by a deceleration. The ECU compares the index to past index statistics, in a case where the object is detected by the object detector and then a response operation against the object by a driver of the vehicle is detected. A driving reaction of the driver of the vehicle is based on a result of this comparison and driving support is executed based on the determination.Type: GrantFiled: August 28, 2014Date of Patent: May 22, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Quy Hung Nguyen Van, Hiroshi Kishi -
