SYSTEM AND METHOD FOR TRACTION CONTROL IN A WORK VEHICLE WITH AN ELECTRIC INFINITELY VARIABLE TRANSMISSION
A work vehicle includes an engine and a transmission assembly having a variator, a gear arrangement, and an electric machine operably connected to the engine and to the variator to provide rotational power to the variator. The transmission assembly selectively transfers power from the engine and/or the electric machine to an output shaft to drive ground engaging elements of the work vehicle. A traction control unit controls the output of the electric machine to provide traction control for the work vehicle, with the traction control unit operating to receive inputs on a commanded ground speed and an actual ground speed of the work vehicle, compare the commanded ground speed to the actual ground speed and, when the commanded ground speed exceeds the actual ground speed by a threshold amount, reduce the speed or torque output of the electric machine, thereby providing traction control for the ground engaging elements.

In a current operation stage, values are determined for one or more furrow characteristics and one or more operating conditions based on received input signals from multiple work machine sensors, a current tool wear state is estimated based on the determined values and by reference to at least one of the learning models, and output signals (e.g., control signals, alerts, and/or display signals) are generated corresponding to the estimated current tool wear state.

Implementations improve object classification/detection by leveraging visual attributes. An image depicting instance(s) of object class(es) is obtained with a textual snippet that includes: noun(s) identifying target object class(es); and adjective(s) describing target visual attribute(s). The textual snippet may be encoded as text embedding(s) that represent target object class(es) and visual attribute(s) in a shared embedding space. The image may be processed using an image encoder to generate image encoder output tokens (IEOTs) that are used to generate object visual embedding(s) in the shared embedding space. The text embedding(s) and the object visual embeddings may be used to classify the IEOTs as depicting an instance of the target object class(es) having target visual attribute(s). The IEOTs may also be processed using a localization head to predict annotation(s) for the digital image.
