Publication number: 20230264931Abstract: A lift vehicle includes a chassis, an implement, a lift arm coupling the implement to the chassis, a load sensor, a tilt sensor, and a controller. The lift arm includes an actuator configured to selectively extend the lift arm and a length sensor configured to provide data relating to a length of the lift arm. The load sensor can provide data relating to a load at the implement. The tilt sensor can provide data relating to an angular orientation of the chassis relative to a reference plane. The controller can receive data from the length sensor, the load sensor, and the tilt sensor. The controller can determine, based on the data from the load sensor and the tilt sensor, an operating envelope for the lift arm. The operating envelope can include a maximum extension of the lift arm. The controller can selectively limit an operation of the lift arm such that the lift arm operates within the operating envelope.Type: ApplicationFiled: February 20, 2023Publication date: August 24, 2023Applicant: Oshkosh CorporationInventors: Dale Tressler, Mark Neubauer, Prabhu Shankar, Michael Buhidar, Alex Dilello, Marcel Amsallen, Kurtis Thrush, Louis Bafile, Matthew Gilbride

Patent number: 8870714Abstract: An auxiliary transmission module has an auxiliary transmission having an input shaft, an output shaft, and a mechanical synchronizer, and a controller. The controller is configured to command a downshift for the auxiliary transmission, control the input shaft to a generally synchronous speed with the output shaft for engagement, and increment the speed of the input shaft by a predetermined speed differential above the speed of the output shaft or engagement if the auxiliary transmission is unengaged after controlling to the generally synchronous speed. A method of downshifting includes commanding a downshift for the auxiliary transmission, controlling an input shaft to a generally synchronous speed with an output shaft for engagement, comparing a rotational speed upstream with a rotational speed downstream to verify engagement, and controlling the input shaft to an asynchronous speed with the output shaft for engagement during a recycle event when it is unverified.Type: GrantFiled: September 13, 2012Date of Patent: October 28, 2014Assignee: Eaton CorporationInventors: Jon Allen Steeby, Marcel Amsallen

Patent number: 6052637Abstract: A control for determining the state of adjustment or misadjustment of a master friction clutch (14) in a vehicular automated mechanical transmission system (10). A system controller (24) receives input signals (26) indicative of the engaged or disengaged condition of the master clutch, the rotational speed of the transmission input shaft (IS) and the engaged or disengaged condition of the mechanical transmission (16). When the master clutch and the transmission both are disengaged, the rate of change of input shaft speed (dIS/dt) is compared to a predetermined reference value, and if the rate of deceleration of the input shaft speed is less than said reference value, significant master clutch misadjustment is determined and corrective action is initiated. Corrective action may include causing a display (48) to signal the operator that the master clutch is improperly adjusted and/or operating an input shaft brake (50) in a fault-tolerant mode.Type: GrantFiled: June 9, 1997Date of Patent: April 18, 2000Assignee: Eaton CorporationInventors: Marcel Amsallen, Timothy J. Morscheck

Patent number: 5479345Abstract: A method and apparatus for selecting gear shift points wherein vehicle speed and grade are monitored by :sensors which provide data which is used to calculate vehicle acceleration adjusted to compensate for the effect of vehicle grade. A gross vehicle weight value is determined from the adjusted acceleration value. Based on the determined gross vehicle weight and the existing grade, the horse power required to sustain the current GVW and grade with zero acceleration is calculated. Also the current GVW and grade are used to determine the rate of vehicle speed loss during the torque interrupt period in order to predict the engine speed in the new gear and calculate the horse power available from the engine at shift completion.Type: GrantFiled: November 2, 1993Date of Patent: December 26, 1995Assignee: Eaton CorporationInventor: Marcel Amsallen
