Abstract
A method and various apparatus are provided for assisting braking in a paving machine having hydraulically driven ground engaging elements driven by a hydraulic motor, and one or more screed electrical heating elements powered by a generator. In the event that the application of the machine deceleration system occurs at a machine speed exceeding a predetermined threshold value, the hydraulic motor of the drive train is configured to drive the hydraulic pump of the hydraulic system. The hydraulic pump is linked to the system generator to generate electrical power to drive the one or more screed electrical heating elements at a current greater than the current previously being provided to the one or more screed electrical heating elements.
