Road paver with heating element for a screed

A road paver comprises a generator, a control device and a screed, the screed comprising a basic screed and being suited to be modified, by selectively attaching or detaching broadening parts, from a first to at least a second, different screed configuration. The basic screed and the broadening parts each comprise one compacting unit and one electric heating element to be supplied with power from the generator for heating the compacting unit to prevent the laying material from adhering to the compacting unit and to finish a high-quality road pavement. The control device is configured to individually switch on or off each one of the two resistance wire windings of the heating element of the basic screed depending on the screed configuration determined by the control device to distribute electrical power generated by the generator to the individual resistance wire windings.

ADJUSTING A SETTING OF A SCREED ASSEMBLY BASED ON TEMPERATURE DATA OF THE SCREED ASSEMBLY

In some implementations, a controller may receive a command to adjust a setting of the screed assembly. The controller may obtain temperature data from one or more sensor devices of the screed assembly. The controller may determine, based on the temperature data, a corresponding temperature of one or more components of the screed assembly. The controller may selectively cause the setting to be adjusted or preventing the setting from being adjusted based on the corresponding temperature of the one or more components, the setting being adjusted based on determining that the corresponding temperature satisfies a temperature threshold, or the setting being prevented from being adjusted based on determining that the corresponding temperature does not satisfy the temperature threshold.
