Patent number: 9090346Abstract: A wing structure includes: a main wing that extends in a second direction intersecting a first direction as a fluid flow direction; and an auxiliary wing that is disposed so as to be separated from the main wing and faces the main wing at the front part side of the main wing, wherein a wing chord length of the auxiliary wing is shorter than a wing chord length of the main wing. A fluid contacts the auxiliary wing which is formed at the front part side of the main wing, the fluid is guided between the auxiliary wing and the main wing, and the fluid is compressed when passing between the auxiliary wing and the main wing, thereby appropriately forming a fluid compression process region on the surface of the main wing and increasing an acting force.Type: GrantFiled: October 7, 2010Date of Patent: July 28, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yukihide Kimura, Tomoaki Morimoto

Patent number: 8960043Abstract: A steering device that is enabled to move and operate in multiple directions and has a simple configuration. A steering device is equipped with a steering member and a guide member, and the guide member is attached to an input shaft. The steering member is provided with left and right grips, and a movement direction changing mechanism is provided between the guide member and the left and right grips. If the left and right grips are operated by a small steering angle, the movement direction of the left and right grips is changed to the direction around the input shaft through the movement direction changing mechanism. When the left and right grips are operated by a large steering angle, the movement direction of the left and right grips is the direction around the input shaft.Type: GrantFiled: March 29, 2010Date of Patent: February 24, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yukihide Kimura, Ryota Osumi

Publication number: 20140265432Abstract: A boundary layer control system includes a boundary layer separating portion that separates a boundary layer of an airflow at an underside of a body of a moving object from a main flow of the airflow, and an ejecting portion that ejects fluid in a state different from that of the boundary layer and the main flow, between the boundary layer and the main flow that have been separated by the boundary layer separating portion. This boundary layer control system is characterized in that boundary layer and the main flow are reliably separated by the fluid in a state different from that of the boundary layer and the main flow, so the percentage of the main flow that is slowed down (i.e., reduced in velocity) by the boundary layer is reduced.Type: ApplicationFiled: October 11, 2012Publication date: September 18, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yukihide Kimura

Patent number: 8788149Abstract: A CPU changes a turning angle corresponding to a steering angle required for a steering device to steer a host vehicle, depending on the amount of operation for moving a steering wheel at a reference position in a tilt direction and a push-pull direction. A tilt reaction force device and a push-pull reaction force device generate a reaction force against a second operation amount for moving the steering wheel from the reference position according to the reference position of the steering wheel relative to the driver which is adjusted by a tilt/expansion mechanism. In this way, even when the reference position of the steering wheel is changed, it is possible to give an appropriate reaction force to the driver since a reaction force against, for example, an operation of pushing or pulling the steering wheel is generated according to the reference position of the steering wheel relative to the driver.Type: GrantFiled: August 5, 2010Date of Patent: July 22, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yukihide Kimura, Ryota Osumi
