In some implementations, a controller may determine whether a machine is operating in an autonomous mode or a manual mode. The controller may cause, based on a determination that the machine has been in an idle state for a first timer period, shutdown of an engine of the machine. The controller may monitor, based on a determination that the machine is operating in the autonomous mode, whether a condition for starting the engine is satisfied. The controller may cause, based on a determination that the engine has been shut down for a second timer period and that the condition is not satisfied, the machine to transition to a low power mode. The controller may cause, when the condition is satisfied, starting of the engine.

A mobile work machine includes a propulsion subsystem that propel the mobile work machine about a worksite. The mobile work machine includes a steering subsystem that steers the mobile work machine about the worksite. The mobile work machine includes a stability determination system that determines a stability factor based on a characteristic of the steering subsystem. The mobile work machine also includes a control system that controls the mobile work machine based on the stability factor.

A vehicle braking control method is provided. When a driver intends to drive a vehicle after the delivery of the vehicle or a factory mechanic intends to test the vehicle before the delivery of the vehicle after the engine is turned on even when a warning light is turned on due to the insufficiency of the brake fluid, a warning signal indicating that a level sensor is malfunctioning is generated using an instrument cluster, or driving torque of the engine is limited while a warning phrase indicating the insufficiency of the brake fluid is displayed using the cluster. Therefore, the vehicle may travel at a minimum speed. Thus, the driver is enabled to drive the vehicle to a safe place. Accordingly, a secondary accident is prevented and a subsequent maintenance operation is easily performed.

A method of calibrating a driving force of a vehicle is provided. A status change of one or more components of the vehicle may be detected by a sensor. One or more models of the one or more components of the vehicle having the status change may be determined by the processing circuitry. The driving force based on the determined one or more models may be calculated by the processing circuitry. The driving force of the vehicle to reach a threshold value may be calibrated.

Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for sanitization of a vehicle interior, activating an ultraviolet germicidal irradiation (UVGI) system and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the vehicle interior above an upper threshold temperature for a threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes while the UVGI system may supplement the heat sanitizing.

A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T1), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T1) being torque obtained by subtracting an amount of increased torque (ΔTmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.

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 method to control a road vehicle provided with a dual-clutch, servo-assisted transmission and standing still with the internal combustion engine turned on; the control method generally includes, when the road vehicle is standing still with the internal combustion engine turned on, the steps of: engaging a forward gear associated with a first clutch; engaging a reverse gear associated with a second clutch, which is different from and independent of the first clutch; closing the first clutch so as to cause the first clutch to transmit a first torque; and closing the second clutch so as to cause the second clutch to transmit a second torque, which is equal to the first torque multiplied by the quotient between a gear ratio of the reverse gear and a gear ratio of the forward gear.

A method of estimating a load on a vehicle (10), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

A method for estimating a longitudinal force difference ΔFx acting on steered axle wheels of a vehicle, the method comprising obtaining data from the vehicle related to an applied steering torque M.sub.steer associated with the steered axle wheels, obtaining a scrub radius value r.sub.s associated with the steered axle wheels, and estimating the longitudinal force difference ΔFx, based on the obtained data and on the scrub radius r.sub.s, as proportional to the applied steering torque M.sub.steer and as inversely proportional to the scrub radius r.sub.s.
