Patent number: 9688310Abstract: Deformation of a vehicle compartment is suppressed at the time of a small overlap collision. A front pillar lower structure (10) includes a gusset (50) joined to a lower end portion of a pillar reinforcement (41). In the gusset (50), a front wall (50B) and a lower wall (50C) extend from a side wall (50A) located on the outer side in a vehicle width direction of a rocker reinforcement. The front wall (50B) covers the rocker reinforcement (29) from the vehicle front side, while the lower wall (50C) extends toward the vehicle rear side from a lower end of the front wall (50B) and is joined to a lower surface of the rocker reinforcement (29). Since the strength of a joint portion (51) between the pillar reinforcement (41) and the rocker reinforcement (29) can be improved by the gusset (50), it is possible to prevent or suppress breakage of the joint portion (51) at the time of a small overlap collision so that deformation of a vehicle compartment (21) due to such breakage can be suppressed.Type: GrantFiled: March 26, 2013Date of Patent: June 27, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Youhei Yamamoto, Daisuke Teramoto, Nobuaki Kitaura

Patent number: 8398148Abstract: A method and system for disengaging a drive rod in a door after an impact to the door. An automobile having a door with a door handle, a drive rod, a latching system, a striker, and a drive rod striking member. The drive rod striking member can be positioned adjacent the drive rod. Upon impact to the door, the drive rod is disengaged from the door handle and/or the latching system through inertia, through the drive rod striking member impacting the drive rod, or through any other disengagement mechanisms. The drive rod striking member prevents the drive rod from re-engaging with the latching system. The disengagement of the drive rod prevents the drive rod from controlling the latching system to disengage from the striker, either through deformation of the door, or through actuations by the door handle.Type: GrantFiled: March 1, 2012Date of Patent: March 19, 2013Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Daisuke Teramoto, Kazuhiro Fukazawa, David L.

Patent number: 8384345Abstract: A control method for a lithium ion secondary battery includes performing a charging step of charging the lithium ion secondary battery with a predetermined quantity of electricity when the battery voltage of the lithium ion secondary battery has decreased to a lower limit battery voltage that is set at a value that falls within a range higher than (B?C) V and lower than or equal to (B?C+0.2) V where a maximum value of a positive electrode potential of a flat portion in a discharge positive electrode potential curve is B (V) and a negative electrode dissolution potential is C (V). It is possible to suppress a dissolution of a negative electrode current collector of the lithium ion secondary battery to prevent the service life of the lithium ion secondary battery from shortening because of an internal short circuit.Type: GrantFiled: June 30, 2009Date of Patent: February 26, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tomitaro Hara, Akira Tsujiko, Takuichi Arai, Tsuyoshi Yano, Daisuke Teramoto, Sachie Yuasa, Keiko Wasada
