Patent number: 11966052Abstract: An alert system includes a display device, a display control unit, and a target recognition unit. The display control unit: when the number of targets recognized by the target recognition unit is equal to or more than an upper limit number, sets a display range of a surrounding icon as a whole circular area; and in a state where the number of targets is equal to or more than the upper limit number and the display range of the surrounding icon is set as the whole circular area, when the number of targets increases, reduces the size of the surrounding icon.Type: GrantFiled: September 23, 2022Date of Patent: April 23, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Masaki Maruyama, Minoru Higuchi, Yuya Kishimoto, Toshiaki Seo, Masuhito Tanaka, Kazuki Takano, Hidehiro Takeda, Misaki Koseki

Publication number: 20220074967Abstract: In an apparatus for calibrating an inertial sensor configured to detect an angular velocity of a vehicle, an angular velocity estimator is configured to estimate a value for an angular velocity of the vehicle based on a value for an attitude of the vehicle and a value for a change in attitude of the vehicle estimated by the attitude estimator, and an error estimator is configured to estimate a value for an angular velocity error that is an error between the value for the angular velocity of the vehicle estimated by the angular velocity estimator and the value for the angular velocity of the vehicle detected by the inertial sensor. A calibrator is configured to calibrate the value for the angular velocity of the vehicle detected by the inertial sensor based on the value for the angular velocity error estimated by the error estimator.Type: ApplicationFiled: September 2, 2021Publication date: March 10, 2022Inventors: Suguru HOCHI, Katsuhiko MUTO, Yuya HIGUCHI

Patent number: 9778046Abstract: A vehicle trajectory calculation method is provided. In the vehicle trajectory calculation method, a travel trajectory of a vehicle in a travel route is calculated based on a GPS signal received at predetermined time intervals with a GPS receiver of the vehicle during traveling. When there is an unmeasurable section where the travel trajectory cannot be normally calculated based on the GPS signal, the travel trajectory in the unmeasurable section is calculating by performing an interpolation based on the calculated travel trajectories in sections anterior to and posterior to the unmeasurable section.Type: GrantFiled: January 8, 2014Date of Patent: October 3, 2017Assignee: DENSO CORPORATIONInventors: Yuusuke Watanabe, Yuya Higuchi

Patent number: 9638529Abstract: In this vehicle orientation detection method detecting the orientation of a vehicle on the basis of measurement data obtained at prescribed time intervals, as long as a speed sensed by a vehicle speed sensor is less than a threshold speed, the vehicle orientation is detected on the basis of a yaw rate sensed by a yaw rate sensor. If the speed detected by the vehicle speed sensor is greater than or equal to the threshold speed, a drift determination is performed. If not determined to be in a drift state, the vehicle orientation is detected on the basis of signals received by a GPS receiver, and if determined to be in a drift state, the vehicle orientation is detected on the basis of the yaw rate sensed by the yaw rate sensor.Type: GrantFiled: January 22, 2014Date of Patent: May 2, 2017Assignee: DENSO CORPORATIONInventors: Yuusuke Watanabe, Yuya Higuchi

Patent number: 8965617Abstract: Various sensors, such as a GPS and a vehicle speed sensor, are used to detect a current position and direction of a vehicle. A normal running direction, which is a running direction specified for a road on which the vehicle runs, is acquired. In a state where a vehicle speed pulse is acquired at the predetermined intervals, it is detected whether the vehicle is placed in a wrong-way driving situation on the basis of the detected current direction of the vehicle and the normal running direction; whereas, in a state where a vehicle speed pulse is not acquired, it is not detected whether the vehicle is placed in the wrong-way driving situation on the basis of the detected current direction of the vehicle.Type: GrantFiled: February 20, 2012Date of Patent: February 24, 2015Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Masatoshi Takahara, Shogo Sugimoto, Kuniaki Tanaka, Kiyoshi Tsurumi, Yuya Higuchi
