Patent number: 12044309Abstract: A method calculates a rotational speed of a node of a linkage in a transmission allows the continued operation of the transmission even when rotational speeds are difficult to sense due to the lack of rotational speed. The method begins by sensing rotational speed at each node to define a sensed rotational speed for each node. The sensed rotational speed at each node is compared to a threshold rotational speed. The sensed rotational speed continues to be used if an absolute value of the sensed rotational speed of the node is greater than the threshold rotational speed. A calculated rotational speed is calculated when the sensed rotational speed is less than the threshold rotational speed. The sensed rotational speed value is replaced with the calculated rotational speed for the node when the sensed rotational speed is less than the threshold rotational speed.Type: GrantFiled: August 30, 2023Date of Patent: July 23, 2024Assignee: Sigma Powertrain, Inc.Inventors: R William Davis, Graham Scott Russell, Daniel E Knieper, John W Kimes

Patent number: 11180131Abstract: A control system for hybrid vehicles for reducing a shock caused by a change in an output torque of a transmission during a shifting operation of a transmission. In the hybrid vehicle, an engine and a first motor are connected to an input side of an automatic transmission, and a second motor is connected to an output side of the automatic transmission. A controller calculates a change in an output torque of the transmission when establishing a predetermined gear stage, based on a torque capacity of an engagement device to be engaged and an input torque to the transmission, and select one of the first motor and the second motor that requires less power to reduce the change in the output torque of the automatic transmission.Type: GrantFiled: November 8, 2018Date of Patent: November 23, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Jonggap Kim

Patent number: 11167765Abstract: Provided is a wheel loader in which the speed position of the transmission can be easily changed with a small number of switches. The wheel loader 1 includes a tilting angle sensor 9 for detecting the tilting angle of the vehicle body. In case that the vehicle body is traveling on an uphill or a downhill with a transmission 33 in a higher speed position than the lowest speed position, and the tilting angle detected by the tilting angle sensor 9 is not smaller than a prescribed threshold value, a transmission control device 45 sends the transmission 33 a command to downshift the transmission 33 one speed position by each operation of a shiftdown switch 62.Type: GrantFiled: March 5, 2019Date of Patent: November 9, 2021Assignee: HITACHI CONSTRUCTION MACHINERY CO., LTD.Inventors: Keisuke Naitou, Ryou Taniguchi

Patent number: 11125572Abstract: There is achieved an electronic control device capable of calculating an optimal travel plan even during dynamic reconfiguration of a calculation circuit configuration. When a driving state changes, a travel plan parameter generation/selection unit divides evaluation calculation units into two blocks and performs reconfiguration of the respective evaluation calculation units a plurality of times via a reconfiguration control unit. While the evaluation calculation units are reconfigured, the evaluation calculation units performs evaluation calculation, and while the evaluation calculation units are reconfigured, the evaluation calculation units perform evaluation calculation. Thus, even while some of the evaluation calculation units are being reconfigured, it is possible to continue evaluation of the travel plan in the rest of the evaluation calculation units.Type: GrantFiled: October 26, 2017Date of Patent: September 21, 2021Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Ryoichi Inada, Tatsuya Horiguchi, Teppei Hirotsu, Hideyuki Sakamoto

Patent number: 11117461Abstract: The invention relates to a drive train for a hybrid vehicle with an internal combustion engine, with a transmission and with an electric machine, wherein the electric machine is arranged between the internal combustion engine and the transmission. The drive train can be provided in a simple, economical and/or space-saving manner in that the transmission comprises at least one overrun-enabled forward gear transmitting traction torque only and at least one overrun-free forward gear. A hybrid vehicle can be operated with a drive train of this kind easily and efficiently in that, when an overrun-enabled forward gear transmitting only traction torque is engaged and while the vehicle speed lies below a certain engagement speed for an overrun-free forward gear and at least one criterion for the presence of a driving torque is established or satisfied, the transmission is shifted into the overrun-free forward gear.Type: GrantFiled: May 16, 2018Date of Patent: September 14, 2021Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Wolfgang Vöge, Jannis Zimmermann
