ELECTRONIC POWER MODULE FOR AN AGRICULTURAL VEHICLE

摘要

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. The microcontroller receives the driver configuration instructions from the CAN bus communications circuit and responsively configures the driver subcircuits according to the driver configuration instructions.
