Abstract
A control unit and a method for determining a steering reference state for a vehicle. A first wheel speed value that is a wheel speed value for a wheel on the vehicle is obtained. At least one second wheel speed value that is a wheel speed value for another wheel on the vehicle is obtained. Using the first and second wheel speed value, a steering reference state is determined, corresponding to travel in a straight line by the vehicle.

A method for determining a steering reference state for a vehicle, comprising:
- obtaining, via a control unit, a first wheel speed value that is based on a wheel speed of a wheel on the vehicle;
- obtaining, via the control unit, at least one second wheel speed value based on a second wheel speed for another wheel on the vehicle;
- determining, via the control unit, whether a steering reference state exists that corresponds to travel in a straight line by the vehicle on the basis of the first and second wheel speed values;
- and
- transmitting a control signal if the steering reference state is determined to exist.
A system for determining a steering reference state for a vehicle, comprising:
- a first wheel sensor;
- a second wheel sensor;
- and
- a control unit, wherein the control unit is configured to obtain a first wheel speed value from the first wheel sensor that is based on a wheel speed of a wheel on the vehicle;
- obtain a second wheel speed value from the second wheel sensor based on a second wheel speed for another wheel on the vehicle;
- determine, whether a steering reference state exists that corresponds to travel in a straight line by the vehicle on the basis of the first and second wheel speed values;
- and
- transmit a control signal if the steering reference state is determined to exist.

- obtaining, via a control unit, a first wheel speed value that is based on a wheel speed of a wheel on the vehicle;
- obtaining, via the control unit, at least one second wheel speed value based on a second wheel speed for another wheel on the vehicle;
- determining, via the control unit, a steering reference state comprising a yaw rate that corresponds to travel in a straight line by the vehicle on the basis of the first and second wheel speed values;
- and
- transmitting a control signal if the steering reference state is determined to exist.
