Publication number: 20210179057Abstract: An automated-parking control unit prevents a brake noise during braking, when causing a vehicle to start moving forward or backward. The automated-parking control unit includes: an environment recognizer to recognize environment of a vehicle; a behavior controller to execute behavior control inclusive of steering and acceleration/deceleration, based on recognized information; a brake hold instructor to suspend the vehicle with the behavior control and hold the suspension until receiving behavior-related operation by a driver; and a brake fluid pressure controller, when the vehicle is made to start moving forward or backward, to estimate a range having a brake noise and increase a change rate of a brake fluid pressure in a brake-noise range having a brake noise, as compared with that in a no-brake-noise range.Type: ApplicationFiled: December 11, 2020Publication date: June 17, 2021Inventors: Yuhei SHINGAI, Yuki NAKADA, Masaaki KAWANO, Yasushi SHODA, Daisuke HANZAWA

Patent number: 10173676Abstract: Provided are a travel assist device capable of producing, in a preferred manner, warning vibrations notifying deviation of a vehicle with respect to a travel path, and a method of controlling the same. A travel assist device includes a travel assist control device that notifies a driver about an anti-deviation direction or a deviation direction by making a steering angular acceleration in the deviation direction and the steering angular acceleration in the anti-deviation direction different from each other when producing warning vibrations, wherein a time-derivative value of a steering angle of a steering wheel is defined as a steering angular velocity, and a time-derivative value of the steering angular velocity is defined as the steering angular acceleration.Type: GrantFiled: April 9, 2015Date of Patent: January 8, 2019Assignee: Honda Motor Co., Ltd.Inventors: Daisuke Hanzawa, Shinnosuke Ishida, Kentaro Yamada, Hiroyasu Kubota, Makoto Ito

Lane outward deviation avoidance assist apparatus and lane outward deviation avoidance assist method
Patent number: 9511768Abstract: A lane outward deviation avoidance assist apparatus includes: a recognition device configured to recognize a travel lane of a vehicle; a deviation recognition part configured to recognize a deviation from the travel lane recognized by the recognition device or a deviation prediction from the travel lane; a control part configured to perform a deviation avoidance control for avoiding the deviation from the travel lane at least by a steering; and a deviation number count part configured to count the number of deviations from the travel lane recognized by the deviation recognition part within a predetermined duration or the number of deviation predictions from the travel lane, wherein the control part performs at least any one of the deviation avoidance control and an alarm output control when the number counted by the deviation number count part reaches n, n being a natural number more than 1.Type: GrantFiled: April 1, 2015Date of Patent: December 6, 2016Assignee: Honda Motor Co., Ltd.Inventors: Makoto Ito, Shinnosuke Ishida, Kentaro Yamada, Daisuke Hanzawa, Hiroyasu Kubota, Hiroyuki Kamiya -
Patent number: 9254842Abstract: The driving support device includes: a recognition section configured to recognize each positions of a specific object and a road marking with reference to peripheral information of a own vehicle acquired by a sensor section configured to acquire the peripheral information; and a control section configured to perform different controls on the own vehicle, with reference to recognition results of the recognition section, depending on whether the specific object is present in a first state or a second state, the first state being a state where the specific object is present in a region more outside than a traveling lane with respect to an imaginary line that extends along a traveling direction of the own vehicle, the second state being a state where the specific object is present in a region on a more central side of the traveling lane with respect to the imaginary line.Type: GrantFiled: October 21, 2014Date of Patent: February 9, 2016Assignee: Honda Motor Co., Ltd.Inventors: Shinnosuke Ishida, Daisuke Hanzawa, Shun Iwasaki
