SYSTEM AND METHOD FOR MANAGING OPERATOR SETTINGS FOR A WORK MACHINE
20230069607 · 2023-03-02 · ·

A work machine, such as a wheel loader, operating in a worksite within a wireless control system includes an operator-specific configuration of machine settings associated with an identification for the operator. As the work machine executes a work function, the operator identification, an initial operator-specific configuration, and sensed performance metrics are transmitted to a control system for the worksite. Linking the operator identification to one or both of the initial operator-specific configuration and the metrics, the control system analyzes performance of the work machine by the operator with increased granularity and flags potential irregularities. A modified operator-specific configuration to change operator performance is returned to the work machine and made to override the initial operator-specific configuration when the operator next takes control of the work machine.

Learning mechanism for autonomous trucks for mining and construction applications

The invention simplifies the process of utilizing mmmg or construction trucks to automatically carry ore, dirt, or other matter from one location to another. Transportation of the dirt, ore, or matter is usually performed using trucks with loaders or excavators. The trucks then take the loads and deposit them in piles, which are then used for the next step of the mining or construction process. The invention uses a teach-and-follow process to establish the trajectories that these paths must follow. The present invention describes a system to record and execute trajectories for autonomous mining and construction trucks. This system comprises one or more sensors that can detect road features, a drive-by-wire kit installed onto the truck(s), a user interface that allows the operator to learn trajectories and “replay trajectories”, and a planning algorithm that creates trajectories which take the vehicle from a starting location to an ending location (final destination), while maintaining the vehicle inside of the allowed driving envelope. The invention allows the user to drive the truck along the desired route and have the truck automatically learn the route using features in the environment to localize. In future runs, the truck is able to automatically follow the learned route.

In a case where an inter-vehicle distance X between the unmanned dump 10 and the manned vehicle 20 is equal to or shorter than a reference distance Y, the unmanned dump 10 decides whether or not vehicle-to-vehicle communication 550 is established between the unmanned dump 10 and the manned vehicle 20. In a case where it is decided that the vehicle-to-vehicle communication 550 is established, the upper limit of the travel speed of the unmanned dump 10 is set to a first speed V1, and in a case where it is decided that the vehicle-to-vehicle communication 550 is not established, the upper limit of the travel speed of the unmanned dump 10 is set to a second speed V2.

GENERATING REFERENCE TRAJECTORIES FOR VEHICLES IN CONFINED AREAS

A computer-implemented method optimizes a reference trajectory for an automated vehicle operating in a confined area, for example, a mine or construction site or the like. The reference trajectory comprises a sequence of reference data points. The method determines a projection of the sequence of reference data points for fitting the sequence of reference data points onto a candidate reference trajectory. The projection smooths the fit of the sequence of reference data to a set of data points forming the candidate reference trajectory subject to one or more constraints. The method quantifies a performance of at least one vehicle task to be performed by the vehicle along the reference trajectory in a simulation of the candidate trajectory and optimizes the quantified performance to obtain an optimal reference trajectory for the vehicle in the confined area.
