Abstract: Methods and systems for adjusting operating parameters of a machine in anticipation of a transition from a current operational state to a predicted subsequent operational state. An electronic controller receives a data stream indicative of actuator settings, sensor outputs, and/or operator control settings and applies a pattern detection AI that is configured to determine a current operational state of the machine based on patterns detected in the data stream. The controller then applies a reinforcement learning AI that is configured to produce as an output one or more target operating parameters based at least in part on a predicted subsequent operational state of the machine. The one or more target operating parameters are applied to the machine and at least one performance metric of the machine is monitored. The reinforcement learning Ai is retrained based at least in part on the monitored performance metric(s).

Abstract: Systems and methods for steering a vehicle that adjust how quickly a selected steering input is achieved based on a speed at which the vehicle is traveling are disclosed. The systems and methods include receiving a steering input, detecting a vehicle speed, and selecting a steering ramp rate that defines how quickly a steering amount corresponding to the steering input is achieved by one or more steerable components of the vehicle. In some implementations, the steering ramp rate may be affected as a result of whether the steering input is greater than or less than a previous steering input.

Abstract: A load sensitive ride system and method is disclosed for a vehicle with an implement movably attached by a boom cylinder. The system includes a payload weight measuring system that measures payload weight and generates a signal indicative of the payload weight, a ride control circuit that adjusts hydraulic flow to and from the boom cylinder; and a controller that receives the signal indicative of the payload weight, and sends compliance commands to adjust ride control compliance based on the signal indicative of the payload weight. The system can include a tire inflation system that adjusts tire pressure. The controller can send inflation commands to adjust tire pressure based on the signal indicative of the payload weight. The compliance commands can depend on the components and compliance adjustment methods of the ride control circuit.

Abstract: A system includes a work vehicle, user interface, and controller. The work vehicle includes a frame, boom, implement, perception sensor, position sensor, and ground speed sensor. The perception sensor senses an approaching environment. The position sensor senses a position of the boom or implement. The user interface includes controls and indicators.

Abstract: A work vehicle includes a torque converter having a lock up clutch and a controller that conditionally allows operation of the lock up clutch in a locked position or an unlocked position. The controller determines a plurality of active work vehicle parameters during operation of the work vehicle and includes a plurality of ready to dig parameters. The controller determines a ready to dig condition or a non-digging condition of the work vehicle by comparing at least two of the active work vehicle parameters to at least two corresponding ready to dig parameters. The controller disallows operation of the lock up clutch in the locked position in response to the ready to dig condition, allows operation of the lock up clutch in locked or unlocked positions in response to a non-digging condition. Operation of the lock up clutch avoids the engine from stalling in a ready to dig condition.
