1. A method, comprising:
- providing power, via an electrical system alternator, to at least one cleaning function of a self-propelled hybrid vehicle;
monitoring an operational load, including an operational state of the at least one cleaning function of the self-propelled hybrid vehicle;
controlling a running state of an internal combustion engine to produce a power output based on the monitored operational load; and
maintaining a threshold charge, via the electrical system alternator, of an electrical system battery pack of the self-propelled hybrid vehicle.

Abstract
The invention relates to a method and system for controlling an engine (552) in a sweeper-scrubber. An electrical system alternator (554) provides power to at least one cleaning function (576, 578, 580) of a self-propelled hybrid vehicle and to driven wheels. The operational load is monitored, and the running state of an internal combustion engine (552) is controlled based on the monitored operational load. A threshold charge, of an electrical system battery pack (556) is maintained.
