Patent number: 12208678Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.Type: GrantFiled: February 14, 2023Date of Patent: January 28, 2025Assignee: SUBARU CORPORATIONInventors: Norio Oowada, Hiroomi Kobayashi, Taichi Murai, Takeshi Yoneda, Yosuke Takebayashi, Minoru Suyama, Tatsuya Takayanagi, Akihiro Nabeshima, Kaoru Sugano

Publication number: 20230219558Abstract: A driving force control system for a vehicle that eliminates backlash in torque transmission paths when decelerating or stopping the vehicle. In the vehicle, a differential unit reverses a torque delivered from a motor to a second output shaft. A controller generates a drive torque by an engine and a control torque by the motor when stopping or decelerating the vehicle. Consequently, a difference between torque delivered from the engine to a first output shaft and torque delivered from the motor to the first output shaft is increased to a first predetermined torque or greater, and torque delivered from the motor to the second output shaft is increased to a second predetermined torque or greater.Type: ApplicationFiled: November 2, 2022Publication date: July 13, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yu INASE, Akira IJICHI, Yoshio ITOU, Taichi KOBAYASHI, Kunihiko USUI
