A remote start system and method for a work machine wherein the system comprises a communication device, an engine starter subsystem, a fluid pressure sensor, and a controller. In a first step, controller receives a wake signal from the communication device, The controller then confirms the lock status of a safety lock on the work machine and outputs an engine start signal to the engine starter subsystem upon confirming the lock status. The controller then receives a fluid pressure signal from the fluid pressure sensor, and outputs an engine stop signal if the fluid pressure signal is below a predetermined threshold after a specified timeframe.

A self-propelled work vehicle is provided with work state estimation and associated control techniques. The work vehicle comprises ground engaging units, a work implement configured for controllably working terrain, and various onboard sensors. A controller is functionally linked to at least the one or more onboard sensors and configured to ascertain a first parameter or operation of the work vehicle, determine a work state of the work vehicle, based at least in part on respective input signals from one or more onboard sensors, and generate a control signal for controlling at least a second parameter or operation of the work vehicle, responsive to the ascertained first parameter or operation and the determined work state. The control signals may be provided for proactive adjustments to engine speed, movements of the work implement, movements of the work vehicle itself, etc.

A remote starting system and method are provided for self-propelled work vehicles having work attachments supported from a main frame thereof. Cameras are arranged with respective fields of vision proximate to the work vehicle, and a communications unit is configured to exchange messages with a user device via a communications network. A local or remote controller is configured to receive first user input comprising a remote startup request for the work vehicle from the user device, and to automatically detect parameters respectively associated with predetermined remote startup conditions, at least one of the parameters comprising images obtained from the cameras. The images are transmitted to the user device, responsive to which second user input is received comprising remote startup confirmation from the user device via the communications network. Responsive to at least the second user input, engine startup is automatically controlled for the work vehicle.

Telematics system and method for conditional remote starting of self-propelled work vehicles

A system and method are provided for determining mistrack conditions in work vehicles such as excavators having first and second tracks. A controller uses data from onboard sensors (e.g., cameras, lidar) having an external field of view to detect a first position of, e.g., a track of the work vehicle relative to a first external point in a local reference system independent of a global reference system and to detect, upon the work vehicle having advanced from the detected first position a predetermined distance, a second position of the at least first component of the work vehicle relative to a second external point in the local reference system. The controller further determines an amount of mistrack error corresponding to a difference between the detected second position and an expected second position, and generates an output signal based on the determined amount of mistrack error.

Automated detection of mistrack conditions for self-propelled work vehicles

A local operator-controlled work machine receives a wake-up call when it is not running. The wake-up call turns on a user interface in the machine. A remote machine configuration system loads a job file onto the machine and the machine turns off again.

In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor movement of the joystick relative to the base housing. The MRF joystick resistance mechanism is controllable to vary a first joystick stiffness resisting movement of the joystick relative to the base housing in at least one degree of freedom. The controller architecture is configured to: (i) detect when unintended joystick motion conditions occur during operation of the work vehicle; and (ii) when detecting unintended joystick motion conditions, command the MRF joystick resistance mechanism to increase the first joystick stiffness in a manner reducing susceptibility of the joystick device to unintended joystick motions.

A working machine includes an undercarriage, a main frame, a swing bearing supporting the undercarriage from the main frame, a swing motor configured to pivot the main frame on the swing bearing about a pivot axis, a boom extending from the main frame along a working direction, and a pivot angle sensor configured to provide a pivot angle signal corresponding to a pivot position of the main frame relative to the undercarriage about the pivot axis. A controller is configured to receive the pivot angle signal and to drive the swing motor automatically.

A counterweight removal protection system and a method of controlling removal of the counterweight to avoid damage to an imaging sensor system of a work vehicle, such as an excavator. The imaging sensor system includes an imaging sensor supported by the counterweight and configured to transmit an imaging sensor signal to a vehicle controller to determine the state of the imaging sensor signal. A user interface in the work vehicle includes a selectable touch button to enable removal of the counterweight depending on the state of the imaging sensor signal. An interlock device prevents lowering the counterweight based on the state of the imaging sensor signal. In one embodiment, the imaging sensor signal is a heartbeat signal.

A work vehicle includes a work implement operatively connected to a frame through an actuator having a cylinder and a piston rod. Control circuitry is operatively connected to the actuator and includes a processer and a memory, wherein the memory is configured to store program instructions and the processor is configured to execute the stored program instructions to: identify one of an initial retracted reference position of the piston rod based on an initial minimum retracted distance or an initial extended reference position of the piston rod based on an initial maximum extended distance; identifying an end of stroke position of the piston rod after identifying one of the initial retracted reference position of the piston rod or the initial extended reference position of the piston rod; and moving the work implement with respect to the work vehicle based on a work implement command modified by the identified end of stroke position.
