Method for positioning at least one wheel holder of a vehicle test bench

A method of positioning at least one wheel support (1;

• 401) of a vehicle dynamometer in relation to the position of a wheel (4;
• 404) in the longitudinal direction of a vehicle standing on the vehicle dynamometer, wherein the wheel support (1;
• 401) has a single roller (402) or a twin roller (2, 3), wherein the wheel support (1;
• 401) is positioned using a drive unit for adjusting (5;
• 405) the position of the wheel support (1;
• 401),
• characterized in that the positioning takes place with a vehicle located on the vehicle dynamometer, wherein the vehicle is held in place during the positioning, at least in relation to its longitudinal direction, wherein the positioning of the wheel support (1;
• 401) takes place as a function of a variable that represents
• a force to be applied by the drive unit and/or
• a torque to be applied by the drive unit and/or
• the power consumption of the drive unit and/or
• the work done by the drive unit when the wheel support (1;
• 401) is moved along a defined distance
• when a specific movement profile of the wheel support (1;
• 401) is achieved during a movement (5;
• 405) in a direction corresponding to the longitudinal direction of a vehicle standing on the vehicle dynamometer.
