Abstract
A computer system comprising processing circuitry configured to obtain speed data, obtain wheel force data, obtain reference ground surface data comprising a set of reference ground surface types, determine a slip power loss and a rolling resistance power loss based on the speed data and the wheel force data, determine a ground surface type for a surface based on the slip power loss and rolling resistance power loss and the set of reference ground surface types and provide control data for the vehicle.

A computer system comprising processing circuitry configured to:
- obtain speed data associated with a ground speed and a rotation speed of a wheel of the vehicle;
- obtain wheel force data associated with a wheel torque and a longitudinal tire force applied to the wheel;
- obtain reference ground surface data comprising a set of reference ground surface types;
- determine a slip power loss and a rolling resistance power loss for a tire of the wheel based on the speed data and the wheel force data;
- determine a ground surface type for a surface in contact with the tire based on the slip power loss and rolling resistance power loss and the set of reference ground surface types;
- and
- provide control data for the vehicle based on the ground surface type.
A computer-implemented method comprising:
- obtaining, by processing circuitry of a computer system, speed data associated with at least one of a ground speed and a rotation speed of a wheel of the vehicle;
- obtaining, by the processing circuitry, wheel force data associated with a wheel torque and a longitudinal tire force applied to the wheel;
- obtaining, by the processing circuitry, reference ground surface data comprising a set of reference ground surface types;
- determining, by the processing circuitry, a slip power loss and a rolling resistance power loss for a tire of the wheel based on the speed data and the wheel force data;
- determining, by the processing circuitry, a ground surface type for a surface in contact with the tire based on the slip power loss and rolling resistance power loss and the set of reference ground surface types;
- and
- providing, by the processing circuitry, control data for the vehicle based on the ground surface type.
