The present disclosure relates to a driving speed control device for an agricultural work vehicle, and a driving speed control method for an agricultural work vehicle, the device comprising: a confirmation unit for confirming set transmission information about a driving device of an agricultural work vehicle, and confirming a transmission mode for controlling an engine and a transmission of the driving device; an acquisition unit, which confirms, from the set transmission information, set revolutions per minute (RPM) relating to RPM of the engine when the transmission mode is an RPM designation mode, so as to acquire transmission information on the basis of the set RPM; and a control unit for controlling the driving device by using the acquired transmission information according to the transmission mode.

The present invention relates to a method for operating a motor vehicle. A request for coupling a power take-off is detected. It is checked (12) whether relevant boundary conditions for coupling the power take-off are fulfilled. If the boundary conditions are fulfilled, a system pressure for actuating the power take-off clutch is built up (16). It is checked (18) whether sufficient system pressure to actuate the power take-off clutch has been built up. When sufficient system pressure has been built up, a confirmation signal is produced (20). In reaction to the confirmation signal, a driving transmission control unit is modified (34) in order to actuate the at least one shifting element of the driving transmission with a higher actuation pressure than with an unmodified driving transmission control unit.

Mowing systems include a mower and, optionally, a remote control unit such as a handheld unit, between which may be provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to monitoring a tilt angle of the mower, and defining or executing different system responses as a function of different first and second conditions that relate to the tilt angle. Another aspect relates to automatic adjustment of a speed setting of the mower's drive system as a function of a power takeoff (PTO) unit of the mower.

A framework for safely operating autonomous machinery, such as vehicles and other heavy equipment, in an in-field or off-road environment, includes detecting, identifying, classifying and tracking objects and/or terrain characteristics from on-board sensors that capture images in front and around the autonomous machinery as it performs agricultural or other activities. The framework generates commands for navigational control of the autonomous machinery in response to perceived objects and terrain impacting safe operation. The framework processes image data and range data in multiple fields of view around the autonomous equipment to discern objects and terrain, and applies artificial intelligence techniques in one or more neural networks to accurately interpret this data for enabling such safe operation.

A method for avoiding a collision of a vehicle with a potential collision object includes defining a safety zone around the potential collision object. The safety zone is located outside a danger zone around the vehicle. The method further includes predicting a trajectory corridor which is covered by the vehicle along a future trajectory and during a certain time period and performing a safety measure on the vehicle in order to avoid a collision of the vehicle with the potential collision object. The safety measure is performed as a function of a geometric comparison of the predicted trajectory corridor with the defined safety zone.

A system for safely operating an automated vehicle includes a first network including a sensor set comprising a plurality of sensors configured to detect the surroundings of the vehicle. The sensor set is coupled to a high-performance electronic control unit (ECU) configured to process the signals of the sensors for orientation, control, and collision avoidance. The system further includes a secure motion-control ECU redundantly coupled to at least one drive element via at least two control signals for controlling the vehicle.
