Patent number: 11370432Abstract: A vehicle control apparatus includes an electric control unit that performs a preceding vehicle trailing control which makes an own vehicle trail a preceding vehicle as an adaptive cruise control, and performs a first brake control which automatically applies a first braking control to the own vehicle when a time-to-collision to a target object is less than a first threshold. In a case where a performing condition for the first brake control has been determined to be satisfied during a performance of the adaptive cruise control, the electric control unit continues performing the adaptive cruise control without performing the first brake control when a deceleration control by the adaptive cruise control is being performed, whereas stops performing the adaptive cruise control when the deceleration control by the adaptive cruise control is not being performed.Type: GrantFiled: April 17, 2020Date of Patent: June 28, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Fukaya, Wataru Ike, Kazuki Nemoto, Yuta Takashina, Yuzo Kaneshige, Jun Tsuchida, Yumi Shimanaka, Masayasu Tanase

Patent number: 10625735Abstract: A driving assistance ECU that serves as a vehicle control apparatus performs traveling control of a vehicle based on a detection result of a radar apparatus that detects a target in the periphery of an own vehicle. An angle calculating unit of the driving assistance ECU calculates an axial misalignment angle that is a misalignment amount of an attachment angle of the radar apparatus by statistically processing angle misalignment information of the radar apparatus acquired at a predetermined cycle. A control processing unit sets the angle misalignment amount of the radar apparatus to a predetermined initial angle until a predetermined initial period elapses after startup, and performs operation restriction on traveling control based on the initial angle. After the initial angle elapses after startup, the operation restriction on traveling control is performed based on a calculation value of the axial misalignment angle.Type: GrantFiled: March 8, 2016Date of Patent: April 21, 2020Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Syogo Matsunaga, Jun Tsuchida, Ichiro Aizawa

Patent number: 10578714Abstract: A vehicle control apparatus performs traveling control of a vehicle based on a detection result of a radar apparatus that detects a target in the periphery of an own vehicle. The vehicle control apparatus calculates a shaft misalignment angle that is a misalignment amount of an attachment angle of the radar apparatus and a shaft misalignment direction, and sets a detection range over which a target to be subjected to traveling control of the own vehicle is detected. Until elapse of a predetermined initial period after startup, a width in a lateral direction of the detection range is reduced based on a predetermined initial angle that is the misalignment amount of the attachment angle of the radar apparatus.

Patent number: 10559205Abstract: A setting unit of an object existence determination apparatus sets an object-existence determination region with a lateral width in the travelling direction of an own vehicle using a lateral speed of a target object and a determination result by a straight-travel determining unit. An existence determining unit determines, based on the lateral position of the target object and the object-existence determination region, whether there is a possibility of at least part of the target object existing on a travelling course of the own vehicle. The setting unit sets the lateral width of the object existence determination region to be larger as the lateral speed becomes higher, and sets, upon determination that the own vehicle is not travelling straight, the lateral width of the object existence determination region to be smaller than the lateral width of the object-existence determination region used when the own vehicle is travelling straight.Type: GrantFiled: March 31, 2016Date of Patent: February 11, 2020Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akitoshi Minemura, Yosuke Ito, Jun Tsuchida, Hitoshi Yuasa
