Patent number: 11794845Abstract: A leaning vehicle, including a vehicle body, one steerable front wheel and two rear wheels, or two steerable front wheels and one or two rear wheels, a suspension mechanism, a steering mechanism, a steering controller, and an up-down direction acceleration detector attached to the vehicle body or the suspension mechanism. The two steerable front wheels or the two rear wheels are arranged side by side to form a left-right pair of wheels. The up-down direction acceleration detector detects an acceleration in an up-down direction of the leaning vehicle or the vehicle body, generated as one wheel in the left-right pair of wheels passes a bump or a pothole in a road. The steering controller so controls the one or two steerable front wheels that the one or two steerable front wheels are in a free-steering state, so as to swivel around a steering axis freely, based on the detected acceleration.Type: GrantFiled: June 25, 2021Date of Patent: October 24, 2023Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Keisuke Terada, Toshifumi Uchiyama, Keizo Araki, Shota Kubo

Publication number: 20210316730Abstract: A leaning vehicle including a vehicle body, a steerable front wheel set swivelable around an axis extending in an up-down direction, a rear wheel set, a turn operation input device that receives a turn operation and transmits the turn operation non-mechanically, a leaning device including a lean actuator that leans the vehicle body, the steerable front wheel set and the rear wheel set to a leftward or rightward direction, and a centripetal force generator including a centripetal force generation actuator, which outputs a controllable torque to thereby generate an additional centripetal force that acts on the steerable front wheel set and the rear wheel set during a turn of the leaning vehicle. The controller controls the torque while controlling the lean actuator in accordance with the received turn operation, to thereby control a leaning condition of the vehicle body during the turn and to control generation of the additional centripetal force.Type: ApplicationFiled: June 25, 2021Publication date: October 14, 2021Inventors: Keisuke TERADA, Toshifumi UCHIYAMA, Keizo ARAKI, Shota KUBO

Patent number: 10899016Abstract: An example system includes a vehicle, a robot, and a controller. The vehicle may include an accelerator operator and a steering operator. The robot may include as accelerator actuator configured to operate the accelerator operator, and a steering actuator configured to operate-the steering operator. The controller is configured to: in response to an accelerator command, send a first signal to the accelerator actuator to operate the accelerator operator of the vehicle, and in response to a steering command, send a second, signal to the steering actuator to steer the vehicle.Type: GrantFiled: October 21, 2016Date of Patent: January 26, 2021Assignees: SRI INTERNATIONAL, YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Thomas Low, Thomas De Candia, Seungkook Yun, Thomas Egan, Bryan Chavez, Alexander Kernbaum, Riley Shear, Leonard Gerard, Stephen Morfey, Richard Mahoney, Regis Vincent, Paul Birkmeyer, Hiroyuki Morita, Hirokatsu Muramatsu, Keiji Nishimura, Hiroshi Saijou, Akira Satou, Toshifumi Uchiyama, Hitoshi Watanabe, Shirou Watanabe

Publication number: 20190210644Abstract: A vehicle includes a main body, a steerable wheel, a steering, a steering actuator, and an electronic controller. The main body includes a saddle. The steerable wheel is coupled to the main body via a suspension. The steering is turnably coupled to the main body to steer the steerable wheel. The steering actuator is configured to apply steering torque to the steerable wheel. The electronic controller is configured to control the steering torque using the steering actuator and configured to generate steering damper torque to the steerable wheel using the steering actuator upon determining a reduced contact of the steerable wheel with a traveling surface with respect to a first prescribed threshold.Type: ApplicationFiled: January 4, 2019Publication date: July 11, 2019Inventors: Toshifumi UCHIYAMA, Thomas P. LOW, Brian W. FOSTER, Huihua ZHAO, Martin GAUDREAULT

Patent number: 6099002Abstract: A foldable walking-assistant device with which the handle's height can be properly adjusted according to the user's height. The device itself can be used as a chair. Moreover, the device can be folded and unfolded easily by the one-touch manner. A left and right leg body each consist essentially of the horizontal leg whose longitudinal length can be adjustable, the handle pipe which is vertically placed on the horizontal leg and is adjustable as to the height of the device, and the rear pipe which is provided at the handle pipe. The leg body possesses the folding mechanism combined with the associated action of the cross bar. The hand brake is installed at the handle pipe.Type: GrantFiled: September 15, 1999Date of Patent: August 8, 2000Assignee: Uchie Co., Ltd.Inventor: Toshifumi Uchiyama

Patent number: 5244223Abstract: A wheelchair formed from a pair of handle pipes, seat pipes, front pipes, rear pipes and two pairs of front and rear cross pipes. The main body of the wheelchair can be folded simultaneously in a front-to-rear, a left-to-right, and up-and-down directions by pivoting the seat pipes toward the handle pipes. Steps are formed in a double-door fashion and are installed, movable in the front-rear direction so that the steps can be storable inside the wheelchair main body, when folded. Foldable and detachable arms are also mounted so as to be folded with the main body.Type: GrantFiled: February 3, 1992Date of Patent: September 14, 1993Inventor: Toshifumi Uchiyama
