Optical sensors (115,145) are used to measure the positions of reference marks formed on the sub-assembly (150). The method has the following stages: a - place the optical sensor (115) on a robot (110); b - place a sub-assembly (150) having a reference geometry in front of the robot (110), and move the robot (110) to positions in which the sensor (115) is each time positioned opposite to a known positioning reference in the vehicles reference domain; c - for each position, record in a control module (110,114,500) the position of the robot (110), trigger the sensor and produce a setting for the measured results of the latter so as to make them correspond to the known positioning of the reference in the vehicles reference domain; d - place the sub-assembly to be controlled in front of the robot (110); e - make the robot (110) repeat the recorded positions and, for each of the positions, measure with the optical sensor (115), the position of the reference using the setting measurement for the robots position determined in stage c, so as to obtain the position of the reference in the reference domain of the vehicle. An Independent Claim decries the control device using the above method
