1. An electronic control unit for a compactor, the electronic control unit comprising:
a processor circuit; and
a memory coupled to the processor circuit, wherein the memory comprises computer readable program instructions that, when executed by the processor circuit, cause the electronic control unit to perform operations comprising:
obtaining a planned operating profile of the compactor, the planned operating profile of the compactor comprising a predicted movement path and a predicted vibration profile for the compactor;
generating a predicted power expenditure schedule for the compactor based on the planned operating profile;
determining, based on the predicted power expenditure schedule, that a predicted energy expenditure of the compactor exceeds an available energy of the compactor;
generating a modified operating profile in response to determining that the predicted energy expenditure of the compactor exceeds the available energy of the compactor; and
operating the compactor according to the modified operating profile,
wherein the predicted power expenditure schedule of the compactor specifies sources of power for the compactor over a range of operation covered by the planned operating profile of the compactor, and
wherein the compactor comprises a hybrid power source including an electric power source and an internal combustion engine, and wherein the predicted power expenditure schedule specifies a first percentage of power supplied by the electric power source and a second percentage of power supplied by the internal combustion engine over a time period covered by the predicted power expenditure schedule, to ensure adequate power is available for the paving operation while reducing emissions.
