Patent number: 11970084Abstract: A vehicle drive device and a control method therefor are provided. The vehicle drive device includes: a power source including a first rotating electrical machine; a second rotating electrical machine; a differential unit including three rotating elements to which a first output shaft, a second output shaft, and the second rotating electrical machine are connected; and an electronic control device. The electronic control device regeneratively controls the first rotating electrical machine and the second rotating electrical machine in such a manner that negative torque is applied to the first output shaft and the second output shaft, when performing regenerative control by the second rotating electrical machine in a drive mode in which torque from the power source is distributed to the first output shaft and the second output shaft by controlling torque of the second rotating electrical machine during deceleration of a vehicle.Type: GrantFiled: February 11, 2022Date of Patent: April 30, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Koji Takaira, Yuki Makino, Akinori Homan, Yosuke Akiyama, Akira Ijichi, Kunihiko Usui

Patent number: 11932137Abstract: A regenerative torque upper limit is set to a larger value when a rear-wheel distribution ratio is small than when the rear-wheel distribution ratio is large. Accordingly, when a distribution of a drive power to front wheels is large, a regenerative torque of a second rotary machine can be increased such that wheels are less likely to slip at the time of performing of regeneration control when the distribution of the drive power to the front wheels is small in comparison with a case in which the regenerative torque upper limit is set to a constant value similarly to when the distribution of the drive power to the front wheels is small. In this way, it is possible to increase the regenerative torque of the second rotary machine according to the rear-wheel distribution ratio.Type: GrantFiled: February 3, 2021Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Masato Nakano, Yuki Makino

Patent number: 8720949Abstract: Recess portions (15) and (16) are disposed in a seat-belt sliding face (14) of a seat-belt sliding member (13), and a predetermined number of projections (17) are provided independently of each other in a dotted state in the recess portions (15) and (16). In each of the projections (17), sliding resistance between a seat belt (4) and the seat-belt sliding member (13) in a normal time is small, and the sliding resistance between the seat belt (4) and the seat-belt sliding member (13) when the seat belt (4) slides to the lap belt (4c) side is larger than the sliding resistance between the seat belt (4) and the seat-belt sliding member (13) when the seat belt (4) slides to the shoulder belt (4b) side. By means of the dotted-state projections (17), extension of the lap belt (4c) in an emergency is suppressed.Type: GrantFiled: September 26, 2011Date of Patent: May 13, 2014Assignee: Takata CorporationInventors: Yuki Tabata, Yoshihiko Kawai

Patent number: 7878546Abstract: A belt guide anchor is provided to improve handling operability of a seat belt even when a belt opening angle between a portion of the seat belt adjacent to a retractor and that adjacent to an occupant is increased. A belt guide anchor has a belt insertion hole into which a seat belt is fitted so as to be slidable and expanded portions formed on surfaces of the belt guide anchor facing the interior and exterior, respectively, of the vehicle adjacent to the belt insertion hole. In one form, a thin portion is formed in the expanded portion on the surface facing the interior of the vehicle at a position adjoining a part of the belt insertion hole facing the front side of the vehicle, and a thin part is formed in the expanded portion on the surface facing the exterior of the vehicle at a position adjoining a part of the belt insertion hole facing the rear side of the vehicle.Type: GrantFiled: April 4, 2008Date of Patent: February 1, 2011Assignee: Takata CorporationInventors: Yuki Tabata, Tadashi Sugiyama
