Abstract

A self-propelling machine for processing bituminous or concrete pavement material, in particular a road finisher or a feeder. The machine comprises an internal combustion engine as a primary drive source, a controller for the engine, said controller receiving control signals, at least one additional drive unit for functional and operational components of the machine as well as at least one hydraulic circuit comprising a hydraulic medium reservoir. The controller is configured for automatically causing starting and/or stopping of the engine in response to receipt of at least one specific control signal.

Claims

1. A self-propelling machine for processing bituminous or concrete pavement material, comprising

a road finisher having an internal combustion engine as a primary drive source,

a controller for the engine, said controller receiving control signals,

at least one pump drive unit, hydraulic-motor drive unit or hydrostatic drive unit for functional and operational components of the road finisher,

at least one temperature sensor configured for measuring the temperature of a screed of the road finisher or of a part of the screed, and for generating a control signal,

at least one hydraulic circuit comprising a hydraulic medium reservoir,

the controller being configured for automatically causing starting and/or stopping of the engine in response to receipt of the control signal from the at least one temperature sensor.

2. The machine according to claim 1 including a starting device for starting the engine in response to receipt of a control signal.

3. The machine according to claim 2, including an energy store for supplying the starting device with energy in the deactivated condition of the engine.

4. The machine according to claim 3, wherein the energy store comprises a battery.

5. A self-propelling machine comprising a road finisher for processing bituminous or concrete pavement material, the road finisher comprising

a screed,

an internal combustion engine as a primary drive source for propelling the road finisher,

a controller for the engine, said controller receiving control signals,

at least one pump drive unit, hydraulic-motor drive unit or hydrostatic drive unit for functional and operational components of the machine,

at least one temperature sensor located on the screed, for generating a control signal,

at least one hydraulic circuit comprising a hydraulic medium reservoir,

and

the controller being configured for automatically causing starting and/or stopping of the engine in response to receipt of the control signal from the at least one temperature sensor.

6. The self-propelling machine of claim 5 which comprises a localization and/or navigation system.

7. The machine according to claim 6 wherein the localization and/or navigation system is configured for generating a control signal for the controller.

8. The machine according to claim 7 including in combination with the localization and/or navigation system means for ascertaining the current distance to and/or an expected time of arrival of some other road works vehicle.

9. The machine according to claim 8 wherein said means are configured for generating a control signal for the controller.
