A method for controlling a powertrain of a vehicle may include: controlling, by a controller, an engine of the vehicle to be operated when an ignition key of the vehicle is in an on state; and determining, by the controller, whether the controller generates a command changing a state of a clutch based on an operation state of the vehicle. The clutch connects or disconnects a crankshaft of the engine and a crankshaft pulley including the clutch. The crankshaft pulley is connected to a generator pulley and an air conditioner compressor pulley via a belt.

An engine power delivery system provides bifurcated power-flow with transmission bypass. An engine power delivery system includes an engine that has an output element. A transmission has an input shaft coupled with the engine output element, wherein the engine is configured to generate more power than the transmission is capable of handling. A multi-speed gearing arrangement is included in the transmission and is coupled to the input shaft. An output shaft is coupled with the gearing arrangement and a vehicle axle is coupled with the output shaft to be driven thereby. A generator is configured to be intermittently driven by the engine. A motor is configured to receive electric power from the generator and to drive the vehicle axle without the transmission exceeding the maximum ii power rating.

In some examples, a controller receives measurement data from a sensor on a vehicle, determines, based on the measurement data, a condition of usage of the vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the selected parameter set on the vehicle.

A vehicle includes an electric machine that generates torque to move wheels of the vehicle, and a controller. The controller operates the electric machine to limit a maximum speed at which the vehicle is driven in reverse such that the maximum speed depends on a number of detected objects behind the vehicle.

A tractor includes an engine, a transmission coupled to the engine, a hydraulic pump driven by the engine, at least one of a tractor implement, attachment, or control moved by the hydraulic pump, a sensor, and a controller coupled to the transmission. The controller is configured to downshift the transmission based on a signal from the sensor.

A machine control system includes an agricultural work machine having an ECU coupled via a system bus to control engine functions, a GPS receiver, data collector, and specialized guidance system including a stored program. The data collector captures agricultural geospatial data including location data for the work machine and data from the ECU, and executes the stored program to: (a) capture geometries of the farm; (b) capture agricultural geospatial data; (c) automatically classify the agricultural geospatial data using the geometries of the farm, into activity/event categories including operational, travel, and ancillary events; (d) aggregate the classified data to create geospatial data events; (e) match the geospatial data events to a model to generate matched events; (f) use the matched events to generate actionable information for the working machine in real time or near real-time; and (g) send operational directives to the agricultural work machine based on the actionable information.

A vehicle control apparatus includes an engine, a refrigerant compressor, a lock up clutch, a throttle valve, and first, second, and third deceleration controllers. The second deceleration controller controls the lock up clutch to a slip state and controls the throttle valve openwise on the condition that the refrigerant compressor is in the stopped state on decelerated travel of a vehicle in a second speed region in which a vehicle speed is lower than a first vehicle speed and higher than a second vehicle speed lower than the first vehicle speed. The second deceleration controller controls the lock up clutch to a disengaged state and controls the throttle valve closewise on the condition that the refrigerant compressor is in the operative state on the decelerated travel of the vehicle in the second speed region.

A wheel loader includes a forward clutch, an accelerator pedal, a brake pedal, and a controller configured to control hydraulic pressure of hydraulic oil supplied to the forward clutch. The controller performs clutch hydraulic pressure control for reducing the hydraulic pressure of the hydraulic oil supplied to the forward clutch according to an operation amount of the brake pedal on condition that at least the brake pedal is operated while the accelerator pedal is being operated. The controller continues the clutch hydraulic pressure control even after the clutch shifts from a complete engagement state to a semi-engagement state by the clutch hydraulic pressure control.

A computing system can determine a probability of precipitation based on Bayesian inference conditioned on probabilities associated with vehicle wiper status, vehicle jerk, vehicle sway, and vehicle lateral offset. The computing system can disable a vehicle lane assist system based on the probability of precipitation and operate a vehicle with the disabled vehicle lane assist system.
