Publication number: 20210327274Abstract: A driving assistance device includes an object detection unit, an acquisition unit acquiring a first value of a relative speed of an approaching object with respect to an own vehicle, a ghost determination unit, and an assistance determination unit. The ghost determination unit calculates a second value of the relative speed of the approaching object in accordance with a speed of the own vehicle and a value of the relative speed of a following object located between the own vehicle and the approaching object; calculates, as a speed difference, an absolute difference between the first value of the relative speed and the second value of the relative speed; calculates, as an azimuth difference, an absolute difference between an azimuth of the following object and an azimuth of the approaching object; and determines whether the approaching object is the ghost target based on the speed difference and the azimuth difference.Type: ApplicationFiled: June 24, 2021Publication date: October 21, 2021Inventors: Hiroki HORI, Takayuki KITAMURA, Koji TAKEUCHI, Iwao IZUMIKAWA, Hiroki SHIMAZU

Publication number: 20210300243Abstract: In a driving assistance apparatus, an area setter is configured to set a warning area on at least one of a left rear side and a right rear side of a subject vehicle. A notifier is configured to provide a notification in response to an object detector detecting an object in the warning area. A determiner is configured to determine initiation and completion of a turn at an intersection during turning of the subject vehicle at the intersection. An area changer is configured to, in response to the determiner determining the initiation of the turn, reduce the warning area in a direction approaching the subject vehicle, and in response to the determiner determining the completion of the turn, expand the reduced warning area according to a traveling state of the subject vehicle after the completion of the turn.Type: ApplicationFiled: April 23, 2021Publication date: September 30, 2021Inventors: Naotsugu SHIMIZU, Koji TAKEUCHI, Iwao IZUMIKAWA, Masaki KAWAKAMI

Patent number: 11130460Abstract: A sensor protector includes two stays and a thin-plate shaped separate sheet held by the stays. The stays are provided on a bracket. The bracket holds a sensor and is fixed at a predetermined position to an outside panel of the body of a vehicle covered with a bumper cover of the vehicle. The sheet extends such that, in the sensor attached state, the sheet divides/partitions a space around the sensor formed between the outside panel of the body and the bumper cover into an upper space which contains the entirety of the detection surface of the sensor and a lower space which does not contain the detection surface of the sensor.Type: GrantFiled: July 22, 2019Date of Patent: September 28, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenji Furumoto, Takuto Kumashiro, Takashi Unno, Shinji Takeo, Koji Takeuchi

Patent number: 11022674Abstract: If a vehicle surroundings monitoring apparatus is equipped with four radars disposed at each of the four corners of the body of a vehicle in order to detect an object around the vehicle, the interfere of the radio waves of the radars likely to occur. As a result, the accuracy for detecting an object by the radars will deteriorate. Specifically, if two of detection areas are adjacent to each other of the radars overlaps with each other and the two of the radars transmits radio waves at the same time, the interfere of the radio waves will occur in the overlapping area. In view of this, the four radars are divided into two groups such that the detection areas of two radars within the group aren't adjacent to each other and transmission period of one of the groups and that of the other of the groups are repeated alternately.Type: GrantFiled: September 18, 2018Date of Patent: June 1, 2021Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, Continental Automotive GmbHInventors: Koji Takeuchi, Takuya Kaminade, Yoji Honma

Patent number: 10723353Abstract: Rear lateral detection (RLL) ECU 10 determines whether or not a lane change assist control (LCA) is being performed. The RLDECU 10 sets a performing condition for performing a rear-end pre-crash safety control (rear PCS control) to a moderate performing condition when the LCA is being performed, and sets the performing condition of the rear PCS control to a normal performing condition when the LCA is not being performed. The moderate performing condition is set such that the rear PCS control is performed more easily compared with the normal performing condition. For example, in the moderate performing condition, a detection area of a target vehicle which is a vehicle subject to the rear PCS control is expanded compared with the detection area in the normal performing condition.Type: GrantFiled: February 14, 2018Date of Patent: July 28, 2020Assignee: Toyota Jidosha Kabushiki KaishaInventor: Koji Takeuchi

Patent number: 9824585Abstract: A collision avoidance apparatus includes an obstacle detection unit to detect an obstacle ahead of a vehicle; an approaching object detection unit to detect an approaching object approaching the vehicle from behind the vehicle; and an electronic control unit to calculate a collision time until the vehicle collides with the obstacle, based on the distance and relative speed of the obstacle, and starts a drive support to avoid a collision with the obstacle when the vehicle speed is a lower limit speed or greater, and the collision time is a threshold or less. When there is a likelihood for the object to collide with the vehicle from behind the vehicle, the electronic control unit lowers the lower limit speed, and/or starts drive support when the collision time is the threshold or less, even when the vehicle speed is less than the lower limit speed.Type: GrantFiled: February 2, 2016Date of Patent: November 21, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Koji Takeuchi
