Patent number: 11167633Abstract: A control method is provided for controlling a declutching of a sliding gear of a vehicle gearbox having dogs. The sliding gear rotates with a shaft of the vehicle gearbox on which the sliding gear moves axially between a declutched position and an engaged position to transmit rotation to a vehicle wheel. The control method comprises applying a zero torque request to all power sources of the vehicle, applying a declutching instruction to the sliding gear, estimating a resistance torque on the dogs in absence of rapid declutching, calculating a residual torque on the dogs as a function of a calculated resistance torque and an anti-disengagement angle of the resistance torque on the dogs, cancelling the residual torque by application of two opposing cancellation torques on the sliding gear, and declutching the sliding gear.Type: GrantFiled: January 4, 2017Date of Patent: November 9, 2021Assignee: Nissan Motor Co., Ltd.Inventors: Ludovic Merienne, Pedro Kvieska

Patent number: 11162548Abstract: A method for operating a dual-clutch transmission of a motor vehicle, wherein a first clutch is operated closed or engaged and in this way a first transmission branch is driven, in which a current actual gear is engaged, and in a pre-selection phase for a gear changed to a desired gear in a second transmission branch, the desired gear is engaged, and in a second clutch, a clutch hydraulic system is filled and, in this way, the second clutch is closed. The gear change shall be made faster. The filling of the clutch hydraulic system is begun already during the pre-selection phase, and, in this case, the clutch hydraulic system is filled in the pre-selection phase but at most up to reaching a touch point of the second clutch.Type: GrantFiled: February 9, 2017Date of Patent: November 2, 2021Assignee: AUDI AGInventors: Andreas Birk, Mathias Weinhardt

Patent number: 11161582Abstract: A vessel propulsion apparatus includes a first transmission path that transmits the power of an engine to a propeller shaft, a second transmission path that transmits the power of a motor to the propeller shaft, and a controller. A first clutch cuts off the power transmission of the first transmission path in a first disconnection state, and permits the power transmission of the first transmission path in a first connection state. A second clutch cuts off the power transmission of the second transmission path in a second disconnection state, and permits the power transmission of the second transmission path in a second connection state. The controller executes tuning control of both the engine and the motor when the first clutch is switched between the first disconnection state and the first connection state and when the second clutch is switched between the second connection state and the second disconnection state.Type: GrantFiled: August 8, 2019Date of Patent: November 2, 2021Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Daisuke Nakamura

Patent number: 11124056Abstract: A vehicle drive apparatus includes a fluid coupling connected to an engine, and a rotating electric machine connected to the engine via the fluid coupling. The fluid coupling has an impeller to which torque having been output from the engine is input, and a turbine facing the impeller. The impeller rotates about a rotation axis. Torque having been output from the impeller is input to the turbine via a fluid. The turbine rotates about the rotation axis. The vehicle drive apparatus has a path provided between an output shaft of the engine and the impeller, the path through which torque having been output from the engine is transmitted to the impeller not via the turbine, and paths through which torque having been input to the impeller is output via the rotating electric machine, passing through a radially outside relative to the impeller with respect to the rotation axis from the impeller via the turbine.Type: GrantFiled: September 8, 2020Date of Patent: September 21, 2021Assignee: EXEDY CORPORATIONInventors: Yuuki Kawahara, Kenji Kitada, Taichi Kitamura, Kohsuke Murata

Patent number: 11077839Abstract: A control system is installed on a vehicle having an electric motor as a drive power source. The control system includes an electronic control unit configured to switch the vehicle between an automatic driving mode using automatic drive control, and a manual driving mode in which the vehicle is operated by a driver. The electronic control unit is configured to limit the load factor of the electric motor, in the case where the temperature of the electric motor is higher than a first threshold temperature when the vehicle travels in the automatic driving mode, and the case where the temperature of the electric motor is higher than a second threshold temperature when the vehicle travels in the manual driving mode. The second threshold temperature is set to a value higher than the first threshold temperature.Type: GrantFiled: March 28, 2019Date of Patent: August 3, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Mitsutaka Matsumura
