Wheel alignment determination and adjustment

A method of diagnosing vehicle wheel alignment, the method comprising:

• providing at a vehicle a measuring device configured to measure a wheel alignment parameter, the measuring device comprising a wireless transmitter configured to remotely transmit a signal related to said wheel alignment parameter;
• positioning a portable remote device, physically separated from said measuring device, in an operating area at, or closely surrounding, a position taken by an operator during wheel alignment adjustment of the vehicle, the portable remote device comprising:
• a wireless receiver configured to receive said signal related to the wheel alignment parameter;
• a controller configured to process said received signal to obtain a value of said wheel alignment parameter;
• a screen configured to display a characteristic information item, representative of the obtained value of said wheel alignment parameter;
• and
• a battery supplying power to the wireless receiver, the controller and the screen;
• and
• physically adjusting wheel alignment of the vehicle while the screen of the portable remote device displays the characteristic information item representative of a value of said wheel alignment parameter obtained by the controller based on said signal received from the measuring device;
• wherein the measuring device comprises, for each side of the vehicle, at least one of:
• a camera, borne by a fixed structure, said signal being related to an image obtained by a camera and related to a wheel or to an optical target mounted on a wheel, and
• an inclination sensor mounted on a wheel, said signal being related to an angle of inclination measured by the inclination sensor with respect to a reference direction;
• and wherein the method comprises:
• processing said signal by the controller of the portable remote device to obtain the value of the wheel alignment parameter measured by the measuring device,
• defining a visually perceivable property of said characteristic information item based on said obtained value, and
• displaying said characteristic information item on said screen positioned at, or adjacent, the operating area to provide the operator with a display of the characterizing information item directly visible at the operating area.
