Abstract: The present disclosure relates to a method of controlling gear selection in a transmission of a vehicle in response to a directional shift requested by an operator and to a control system for controlling gear selection to manage directional shifts in vehicles, from a first direct to a second direction (e.g. forward to reverse). The method compares the current transmission output speed with a predetermined direction shift threshold transmission output speed. If the current transmission output speed is less than or equal to the predetermined direction shift threshold transmission output speed, the transmission is caused to execute a direction shift from the initial first direction gear to the same second direction gear, or a next highest second direction gear if there is no second direction gear which corresponds to the initial first direction gear. If the current transmission output speed is greater than the predetermined direction shift threshold transmission output speed, the direction shift is inhibited until the current transmission output speed slows to less than or equal to the predetermined direction shift threshold transmission output speed.

Abstract: A method of controlling gear selection in a vehicle transmission comprises detecting a change in a direction control signal (DCS) from a neutral signal state. If the current TOS is less than or equal to a predetermined neutral shift threshold TOS, the transmission selects one of a plurality of first direction gears if the DCS was changed to a first direction signal state or one of a plurality of second direction gears if the DCS was changed to a second direction signal state. If the current TOS is greater than the predetermined neutral shift threshold TOS, the transmission selects one of the plurality of first direction gears if a machine motion direction parameter indicates that the vehicle is moving in the first direction or one of the plurality of second direction gears if the machine motion direction parameter indicates that the vehicle is moving in the second direction.

Abstract: A machine includes an engine, an electronic display device, and a controller configured to: receive one or more signals indicating an identification of a machine operator; retrieve a name of the operator associated with the identification of the operator in a first data set of machine operators; retrieve one or more saved machine parameters associated with the name of the operator in a second data set of machine parameters; and set one or more current machine parameters to the one or more saved machine parameters.

Abstract: A controller of a machine identifies that a battery of the machine is connected to an electrical power connector component. The controller then causes one or more charging components of the battery of the machine to be enabled, then cause one or more electrical components associated with the battery of the machine to be enabled, then causes one or more cooling components of the machine to be enabled, then causes one or more propulsion components of the machine to be disabled, then causes one or more accumulator components of a hydraulic system of the machine to bleed, and then causes one or more non-accumulator components of the hydraulic system of the machine to be enabled. In this way, the controller causes the battery of the machine to enter into a charging state.
