Abstract
The invention relates to a method and system for controlling an engine () in a sweeper-scrubber. An electrical system alternator () provides power to at least one cleaning function () of a self-propelled hybrid vehicle and to driven wheels. The operational load is monitored, and the running state of an internal combustion engine () is controlled based on the monitored operational load. A threshold charge, of an electrical system battery pack () is maintained.
