Abstract: An agricultural harvester comprises an agricultural harvester vehicle and a harvesting head mounted on the vehicle, the header height control system including at least one sensor disposed to sense the height of the ground in the path of a drive wheel of the agricultural harvester vehicle, and a header height control system including an electronic circuit configured to lower the harvesting head as a wheel or wheels approach or engage a protrusion on the ground indicated by the sensor, and to raise the harvesting head as the wheels approach or engage a depression in the ground indicated by the sensor.

Abstract: An electronic power module (EPM) for an agricultural vehicle is provided. The EPM is configurable by an electronic control unit (ECU) to which it is connected by way of a controller area network (CAN) bus. The CAN bus network includes a plurality of electronic control unit (ECU)s and a plurality of EPMs, wherein each of the EPMs is coupled to a corresponding ECU of the plurality of ECUs to be controlled thereby. Each EPM includes an EPM circuit having at least one microcontroller, a driver circuit and a CAN bus communication circuit. The driver circuit is coupled to the microcontroller and is configured by the microcontroller. The driver circuit has a plurality of driver subcircuits. The CAN bus communication circuit is coupled to the microcontroller configured to receive CAN bus messages that include driver configuration instructions and driver current limits from a corresponding ECU and instructions to the microcontroller.
