Abstract: According to one variant, a road finisher having a primary drive unit, a material hopper and a paving screed with a screed heating system that can be operated by energy generated by the primary drive unit is controlled. The screed heating system is operated to heat the screed during paving operation of the road finisher by controlling a temperature of the screed to a predetermined screed operating temperature value or to a predetermined screed operating temperature range. The road finisher anticipates a future operating state of increased energy demand of the road finisher. When a future operating state of increased energy demand has been detected, the screed heating system is operated to heat the screed beyond the predetermined screed operating temperature value or the predetermined screed operating temperature range. When the operating state of increased energy demand is reached, the screed heating system is at least temporarily deactivated.
