Patent number: 11499891Abstract: A tire tester includes a plurality of tire holding units attached to a movable member or a towed member and each configured to detachably hold a tire, and one or more load measuring units for measuring a load acting on the tire. The plurality of tire holding units include a first tire holding unit configured to detachably hold a first tire, and one or more second tire holding units each configured to detachably hold a second tire. The second tire holding unit holds the second tire to generate a force opposite to a lateral component force generated by steering the first tire. The tire holding units are arranged such that at least one tire holding unit is disposed on each right and left side of the movable member or the towed member with respect to a center line passing through a lateral center thereof.Type: GrantFiled: August 10, 2020Date of Patent: November 15, 2022Assignee: HITACHI ASTEMO, LTD.Inventors: Yasuji Shibahata, Tatsuru Niihara, Miki Isshiki, Shigeharu Shibahata, Hirokazu Fujimoto

Patent number: 10889194Abstract: During travel of the electric vehicle, the charging arm is extended in the vehicle width direction, a positive electrode overhead line of the power supply device and a positive electrode power reception unit of the charging arm are brought into contact at the same time that a negative electrode overhead line of the power supply device and a negative electrode power reception unit of the charging arm are brought into contact, and a power storage device for driving the electric vehicle is charged. A charging head that is the tip section of the charging arm is held within a V-shaped groove to which the positive electrode overhead line and the negative electrode overhead line are attached, thereby minimizing the loss of contact even if the charging arm shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.Type: GrantFiled: January 23, 2019Date of Patent: January 12, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Takamitsu Tajima, Yasuji Shibahata, Wataru Noguchi

Patent number: 8271175Abstract: A control means for controlling actuators of a vehicle creates a time series of a future behavior of the vehicle using a vehicle model. A state amount of the vehicle model is initialized on the basis of a state amount of the vehicle, and the future behavior is created starting from the initial state amount. The future behavior is created such that operation commands of the actuators in the vehicle model at the current time coincide with or approximate basic values based on operation of a manipulating device, such as a steering wheel of the vehicle. It is evaluated whether vehicle motion, road surface reaction force, and wheel sliding, in the created future behavior satisfy predetermined restrictive conditions. Based on the evaluation result, the operation commands of the actuators are successively decided. This permits ideal travel of the vehicle to be achieved by properly predicting future behaviors of the vehicle.Type: GrantFiled: August 7, 2006Date of Patent: September 18, 2012Assignee: Honda Motor Co., Ltd.Inventors: Toru Takenaka, Yasuji Shibahata

Patent number: 8095272Abstract: A rotatable grip (ancillary operation member) is provided on a part of a steering wheel body of a steering wheel (main operation member) for turning wheels. When the grip is rotated, a difference is generated between left and right wheels, and a yaw moment generated with this difference can assist or suppress the turning of a vehicle. Because the grip constitutes a part of the steering wheel body, it is possible to rotate the grip to assist or suppress the turning of the vehicle, while operating the steering wheel to turn the vehicle. Because both the steering wheel body and the grip can be operated by the same hand of a driver, operational burden on the driver is alleviated. Thus, it is possible to concurrently provide an excellent operability of the main operation member for controlling a kinetic state of the vehicle, and an excellent operability of the ancillary operation member for controlling the operation of a yaw moment generating device.Type: GrantFiled: September 18, 2007Date of Patent: January 10, 2012Assignee: Honda Motor Co., Ltd.Inventors: Kazuasa Suzuki, Minoru Higuchi, Yasuji Shibahata
