Abstract
The present disclosure relates to a method determining wheel alignment parameter of a vehicle comprising a vehicle body. In particular, the method is performed by attaching a measuring arrangement to positions at a first and second longitudinally extending side portions of the vehicle body, respectively. A first and a second lateral center position are determined whereby a wheel alignment parameter in the form of a longitudinally extending centerline of the vehicle is determined.
Claims12
A method for determining wheel alignment parameter of a vehicle comprising a vehicle body, wherein the vehicle body comprises a first and a second longitudinally extending side portion, the method comprising the steps of:
- attaching a measuring arrangement to a first position at the first longitudinally extending side portion of the vehicle body;
- determining a lateral, longitudinal and vertical coordinate position of the first position at the first longitudinal side portion;
- attaching the measuring arrangement to a first position at the second longitudinally extending side portion of the vehicle body, the longitudinal and vertical coordinate positions of the first position at the second longitudinally extending side portion corresponding to the longitudinal and vertical coordinate positions of the first position at the first longitudinal side portion, respectively;
- determining a lateral coordinate position of the first position at the second longitudinal side portion;
- attaching the measuring arrangement to a second position at the first longitudinally extending side portion of the vehicle body;
- determining a lateral, longitudinal and vertical coordinate position of the second position at the first longitudinal side portion;
- attaching the measuring arrangement to a second position at the second longitudinally extending side portion of the vehicle body, the longitudinal and vertical coordinate positions of the second position at the second longitudinally extending side portion corresponding to the longitudinal and vertical coordinate positions of the second position at the first longitudinal side portion, respectively;
- determining a lateral coordinate position of the second position at the second longitudinal side portion;
- determining, using the lateral coordinate position of the first position at the first longitudinally extending side portion and the lateral coordinate position of the first position at the second longitudinal side portion, a first lateral center position of the vehicle;
- determining, using the lateral position of the second position at the first longitudinally extending side portion and the lateral position of the second position at the second longitudinal side portion, a second lateral center position of the vehicle;
- and
- determining a wheel alignment parameter in the form of a longitudinally extending centerline of the vehicle, the longitudinally extending centerline extending between the first lateral center position and the second lateral center position.

A system for determining wheel alignment parameter of a vehicle comprising a vehicle body, the system comprises a measuring arrangement and a control unit, wherein the control unit is configured to:
- determine a lateral, longitudinal and vertical coordinate position of a first position at a first longitudinally extending side portion of the vehicle body by receiving a control signal from the measuring arrangement when the measuring arrangement is attached to the first longitudinally extending side portion;
- control the measuring arrangement to be attached to a first position at a second longitudinally extending side portion of the vehicle body, wherein the longitudinal and vertical coordinate positions of the first position at the second longitudinally extending side portion corresponds to the longitudinal and vertical coordinate positions of the first position at the first longitudinal side portion, respectively;
- determine a lateral coordinate position of the first position at the second longitudinal side portion;
- determine a lateral, longitudinal and vertical coordinate position of a second position at the first longitudinally extending side portion of the vehicle body by receiving a control signal from the measuring arrangement when the measuring arrangement is attached to the first longitudinally extending side portion;
- control the measuring arrangement to be attached to a second position at the second longitudinally extending side portion of the vehicle body, wherein the longitudinal and vertical coordinate positions of the second position at the second longitudinally extending side portion corresponds to the longitudinal and vertical coordinate positions of the second position at the first longitudinal side portion, respectively;
- determine a lateral coordinate position of the second position at the second longitudinal side portion;
- determine, using the lateral coordinate position of the first position at the first longitudinally extending side portion and the lateral coordinate position of the first position at the second longitudinal side portion, a first lateral center position of the vehicle;
- determine, using the lateral position of the second position at the first longitudinally extending side portion and the lateral position of the second position at the second longitudinal side portion, a second lateral center position of the vehicle;
- and
- determine a wheel alignment parameter in the form of a longitudinally extending centerline of the vehicle, the longitudinally extending centerline extending between the first lateral center position and the second lateral center position.
