Abstract
A compactor for operation on a surface includes: a frame; at least one compacting drum coupled to the frame; a drive system for accelerating and decelerating the compactor at an acceleration rate and a deceleration rate, respectively; and a controller for: controlling the drive system, and based on at least one variable, altering at least one of the acceleration rate and the deceleration rate.
Claims20
A compactor for operation on a surface, the compactor comprising:
- a frame;
- at least one compacting drum coupled to the frame;
- a drive system configured to accelerate and decelerate the compactor at a plurality of acceleration and deceleration rates, respectively;
- and
- a controller associated with a plurality of drive modes associated with the plurality of acceleration and deceleration rates, configured to:
- control the drive system, and
- based on at least one variable, place the compactor in a first drive mode, of the plurality of drive modes, associated with a first acceleration rate and a first deceleration rate of the plurality of acceleration and deceleration rates.
A paving system for applying a paving material, the paving system comprising:
- a paver, comprising:
- at least one auger configured to apply the paving material;
- a first thermal scanner configured to sense a first surface temperature of a surface of the paving material at a location behind the paver with respect to a direction of travel of the paver;
- and
- a transmitter configured to transmit a first signal representative of the first surface temperature, and
- at least one compactor, comprising:
- a frame;
- at least one compacting drum coupled to the frame;
- a drive system configured to propel the at least one compactor at a plurality of acceleration and deceleration rates;
- a receiver configured to receive the first signal;
- and
- a compactor controller, associated with a plurality of drive modes associated with the plurality of acceleration and deceleration rates, configured to:
- determine, based on the first signal, whether the first surface temperature meets or exceeds a first temperature threshold, and
- place, based on determining whether the first surface temperature exceeds the compactor in a first drive mode, of the plurality of drive modes, associated with a first accelerate rate and a first deceleration rate of the plurality of acceleration and deceleration rates,
- wherein at least one of the first acceleration rate or the first deceleration rate is different from at least one of a second acceleration rate or a second deceleration rate, of the plurality of acceleration and deceleration rates, respectively.
A method for operating a compactor on a surface, the method comprising:
- operating the compactor in a first drive mode, the first drive mode comprising a first set of acceleration and deceleration ramp rates for the compactor;
- determining a first variable with respect to an environment of the compactor;
- and
- based on the first variable, switching the compactor into a second drive mode, the second drive mode comprising a second set of acceleration and deceleration ramp rates for the compactor,
- wherein ramp rates of the first set of acceleration and deceleration ramp rates are faster than ramp rates of the second set of acceleration and deceleration ramp rates.
