Abstract
A method for determining a material distribution condition in a tipper body of a tipper vehicle during a tipping event, the tipper body having a longitudinal extension along a longitudinal axis, and being arranged to be pivoted about a transversal axis, perpendicular to the longitudinal axis, during the tipping event, the method comprising generating an image of a surface of the material in the tipper body during the tipping event, and determining the material distribution condition in the tipper body using the image. A method for controlling a tipping event using the method, to a system, and to a vehicle are also disclosed.

A method for determining a material distribution condition in a tipper body of a tipper vehicle during a tipping event, the tipper body having a longitudinal extension along a longitudinal axis, and being arranged to be pivoted about a transversal axis, perpendicular to the longitudinal axis, during the tipping event, the method comprising:
- generating, by a control unit, an image of a surface of the material in the tipper body during the tipping event,
- determining, by the control unit, the material distribution condition in the tipper body using the image, and
- in response to determining a risk of the vehicle, applying, by the control unit, at least one countermeasure to balance the vehicle during the tipping event using the material distribution condition.
A method for controlling a tipping event of a tipper body of a tipper vehicle, the tipper body having a longitudinal extension along a longitudinal axis, and being arranged to be pivoted about a transversal axis, perpendicular to the longitudinal axis, during the tipping event, the method comprising:
- determining, by control unit, a material distribution condition in the tipper body of the tipper vehicle during a tipping event by:
- generating, by the control unit, an image of a surface of the material in the tipper body during the tipping event,
- determining, by the control unit, the material distribution condition in the tipper body using the image,
- determining, by the control unit, an overturn parameter indicative of a risk of the tipper vehicle overturning using the material distribution condition, and
- in response to determining that the overturn parameter indicates a risk of the tipper vehicle overturning exceeding a risk threshold, initiating, by the control unit, a countermeasure to balance the vehicle.
A system for determining a material distribution condition in a tipper body of a tipper vehicle during a tipping event, the tipper body having a longitudinal extension along a longitudinal axis, and being arranged to be pivoted about a transversal axis, perpendicular to the longitudinal axis, during the tipping event, the system comprising:
- one or more imaging devices configured for generating an image of a surface of the material in the tipper body during the tipping event, and
- a control unit configured for determining a material distribution condition in the tipper body using the image;
- wherein the system is adapted to apply at least one countermeasure to balance the vehicle during the tipping event using the material distribution condition.
