Abstract
A method for determining a change in an angle of attack of a screed on a paving machine includes determining a first angle of attack of the screed, determining a second angle of attack of the screed based on data from at least one sensor located on the screed and at least one sensor located on a frame of the paving machine, and determining a change in the angle of attack based on the first angle of attack and the second angle of attack. The method also includes providing a notification of at least one of the first angle of attack, the second angle of attack, or the change in the angle of attack.

A method for determining a change in an angle of attack of a screed on a paving machine, the method comprising:
- determining a first angle of attack of the screed;
- determining a second angle of attack of the screed based on data from at least one sensor located on the screed and at least one sensor located on a frame of the paving machine, the at least one sensor located on the frame of the paving machine being spaced away from a screed assembly that includes a pair of tow arms;
- determining a change in the angle of attack based on the first angle of attack and the second angle of attack;
- and
- providing a notification of at least one of the first angle of attack, the second angle of attack, or the change in the angle of attack.
A method for determining a change in an angle of attack of a screed on a paving machine, the method comprising:
- determining a first angle of attack of the screed;
- determining a second angle of attack of the screed based on data from at least one sensor located on the screed and at least one sensor located on a frame of the paving machine or an averaging ski;
- and
- determining a change in the angle of attack based on the first angle of attack and the second angle of attack;
- and
- automatically adjusting the angle of attack, including automatically adjusting at least one of a counter balance of the screed or a pre-strikeoff height of the screed, in response to the change in the angle of attack.
A system for a paving machine, comprising:
- a frame;
- a screed assembly including a screed and a pair of tow arms;
- a sensor system including:
- at least two sensors arranged on the screed;
- and
- at least one sensor located on the frame of the paying machine spaced away from the screed assembly;
- and
- a controller for determining a change in an angle of attack of the screed or a cross slope, the controller being configured to:
- determine a first angle of attack of the screed;
- determine a second angle of attack of the screed based on data from at least one of the at least two sensors of the sensor system located on the screed and the at least one sensor located on the frame of the paving machine;
- determine a change in the angle of attack based on the first angle of attack and the second angle of attack;
- determine a cross slope of the screed based on data from the at least two sensors of the sensor system located on the screed;
- and
- provide a notification of at least one of the change in the angle of attack or the cross slope.
