Abstract
A control method is disclosed for maintaining a calibrated minimum load for an engine in a vehicle powertrain with an engine. The possibility of engine misfire due to low engine loads is reduced. Further, undesired high temperature of an engine exhaust gas catalytic converter due to prolonged operation of the powertrain at low engine loads is avoided.
