Patent number: 12234892Abstract: A continuous variable planetary (CVP) system includes a CVP hub, which includes a shift mechanism including a shift driver element, and a processing server system to calibrate the CVP system and detect errors within the CVP system. The processing server system performs continuously monitoring or obtaining a transmission speed ratio of the CVP hub. Upon detecting that the transmission speed ratio reaches a particular value, the processing server system records a corresponding position of the shift driver. The processing server system calibrates the CVP system based on the particular value, the corresponding position, and a known relationship between transmission speed ratios and positions of the shift mechanism. The processing server system determines or verifies a full underdrive (FUD) position by iteratively reducing a transmission speed ratio from the particular value until an onset of a backlash condition is detected and determines or verifies a full overdrive (FOD) position.Type: GrantFiled: February 6, 2024Date of Patent: February 25, 2025Assignee: enviolo B.V.Inventors: Marko Matenda, Brad Pohl, Thomas William Ryan, IV

Patent number: 10071629Abstract: A prime mover control device of a work vehicle equipped with a torque converter includes: a speed ratio calculation unit that calculates a speed ratio of the torque converter; and a rotational speed limit unit that, when a speed ratio falls within a preset speed ratio range, limits a maximum rotational speed of the prime mover to be lower as compared with a maximum rotational speed set when a speed ratio falls without the preset speed ratio range. When a state in which the speed ratio calculated by the speed ratio calculation unit falls within the preset speed ratio range is maintained for a predetermined time period, the rotational speed limit unit changes a maximum rotational speed of the prime mover to a higher maximum rotational speed than the limited maximum rotational speed limited to be lower by the rotational speed limit unit.Type: GrantFiled: November 30, 2015Date of Patent: September 11, 2018Assignee: KCM CorporationInventors: Isamu Aoki, Koji Hyodo, Tetsuji Tanaka, Masaki Nukii

Patent number: 9890851Abstract: A system and method of controlling the operation of a transmission using fuel consumption data. The system and method includes controlling the operation of a vehicle transmission which is operatively connected to an engine having operating characteristics and operatively connected to a transmission control module having access to a memory. Fuel consumption data for an engine is converted to engine efficiency loss data representative of the engine operating. A set of polynomials is determined to provide a pattern representative of the operating characteristics the engine. A transmission controller using the pattern determines a prospective operating condition of the transmission to provide fuel efficient operation of the engine.Type: GrantFiled: December 3, 2015Date of Patent: February 13, 2018Assignee: Allison Transmission, Inc.Inventors: Jessica Anderson, John A.

Patent number: 9850836Abstract: An automatic control apparatus for an engine detects an operation position of a mechanical shift lever for shifting gears of a transmission, automatically stops the engine when a predetermined condition is satisfied in the case where the operation position is at a first specific range, and automatically restarts the engine in the case where, after the operation position is switched from the first specific range to a second specific range while the engine is stopped, the second specific range is maintained for a predetermined time. When the operation position is switched from the first specific range to the second specific range while the engine is stopped, it is determined whether or not the driver has an intention to start the vehicle, and if YES, the predetermined time is set to be shorter than when it is determined that there is no intention to start the vehicle.Type: GrantFiled: February 27, 2015Date of Patent: December 26, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasutaka Oda, Hiroaki Tabuchi, Yu Sakai

Patent number: 9694822Abstract: The present invention relates to a vehicle controller (1) for activating a vehicle glide mode. The controller (1) receives vehicle operating data including torque request data representative of a torque request; acceleration data representative of vehicle acceleration; and output torque data representative of an output torque. The controller (1) is configured to analyze the vehicle operating data to identify a vehicle glide opportunity. The controller (1) is operative to generate an activation signal (4) for activating the vehicle glide mode when said vehicle glide opportunity has been identified and the torque request is positive. The controller is thereby operative to implement a vehicle glide strategy. The controller (1) can also operate to deactivate the vehicle glide mode. The present invention also relates to a method of activating a vehicle glide mode.Type: GrantFiled: September 9, 2014Date of Patent: July 4, 2017Assignee: JAGUAR LAND ROVER LIMITEDInventor: Ben Neaves
