  • Patent number: 11937525
    Abstract: A combination of a tractive machine and plow, has a driver assistance system having an input/output unit. The plow is adjustable with machine parameters, wherein a portion is manually adjustable and/or automatically adjustable by means of the tractive machine. A plow adjust assistant determines in a dialog with an operator in a plurality of dialog steps, optimized machine parameters of the plow and/or of the tractive machine that are to be adjusted. The plow adjust assistant automatically adjusts a portion of the machine parameters determined in the first dialog step and/or gives the operator a portion for adjusting and determines further optimized machine parameters of the plow based on these machine parameters and gives these further optimized machine parameters of the plow to the operator for adjustment of the plow in a second dialog step and/or automatically adjusts them at the plow.

    Abstract: A method and a system for monitoring the operation of at least one autonomous agricultural production machine is disclosed. The method comprises collecting data representing the operating parameters and environmental parameters of the autonomous agricultural production machine and detecting an irregularity based on the data. Once an irregularity is determined, the collected data are transmitted to a database and saved there. The irregularity is identified by processing the collected data in an analysis routine, and an instruction is generated for switching the autonomous agricultural production machine from a safe operating state to a normal operating state depending on the identified irregularity, and the instruction is executed.

  • Publication number: 20230345856
    Abstract: A method for monitoring autonomous agricultural production machines is disclosed. The autonomous agricultural production machine autonomously performs an agricultural job. When an anomaly occurs, the autonomous agricultural production machine performs a response routine, interrupting the performance of the agricultural job. The autonomous agricultural production machine senses anomaly data during and/or after the response routine and transmits the anomaly data to a remote monitoring center in a reporting routine that a user may access in the remote monitoring center. The remote monitoring center generates, based on the anomaly data, a control instruction and transmits the control instruction to the autonomous agricultural production machine to execute in order to further respond to the anomaly and thereafter continue to perform the agricultural job.

  • Publication number: 20230350426
    Abstract: A method and a system for deployment planning and coordinating a vehicle fleet comprising a plurality of agricultural work vehicles is disclosed. Different agricultural work processes may be performed on a field with the work vehicles having a work unit for performing at least one of the agricultural work processes. At least one work vehicle of the vehicle fleet is operated autonomously. Further, the database-driven management system may generate the deployment plan. For example, while planning a particular agricultural work process comprising a sequence of work steps, the work vehicles in the vehicle fleet are coordinated with one another by assigning at least one autonomous work vehicle to a respective work step of the agricultural work process with operational parameters being transmitted to the autonomous work vehicle in order to perform the assigned respective work step.
