Patent No. EP4066077 (titled "Method And Control Arrangement For Operating An Autonomous Agricultural Vehicle") was filed by Delaval Holding on Nov 24, 2020. The application was issued on Oct 25, 2023.
A method for operating an autonomous agricultural vehicle in a livestock area utilizes a cleaning device and a load sensor to execute a cleaning plan comprising a schedule and one or more routes. The method monitors load quantities at multiple individual times to represent the amount of material moved by the cleaning device. Based on variations in these monitored load quantities, the cleaning plan is adjusted by modifying the cleaning schedule or routes. Adjustments may include increasing cleaning frequency during time intervals with higher average loads or adapting routes based on position-specific load variations. The system may further calculate material accumulation patterns, predict future accumulation rates, incorporate user-defined cleanliness levels, and calibrate sensors against material-free areas to optimize efficiency and energy use.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
