Method for operating an identification device of a seat, as well as an identification device

A method for operating an identification device (10) of a seat (12) of a motor vehicle, in which an identification of a child car seat on the seat (12) or of an adult on the seat (12) is carried out by an electronic computing device (24) of the identification device (10), and in which, depending on the identification, an airbag apparatus of the seat (12) is activated, and in which a relative variance (34) is determined from a ratio of a pressure variance of a pressure on the seat (12) and an acceleration variance of an acceleration of the motor vehicle during a movement of the motor vehicle and, depending on the relative variance (34), the identification is carried out and the airbag apparatus is activated, comprising the steps of:

• determining a speed variance (30) of a speed (28) of the motor vehicle by the electronic computing device (24) and, depending on the determined speed variance (30), deciding whether the identification is carried out during the movement of the motor vehicle;
• wherein an identification on a basis of a currently determined relative variance (34) is suppressed above a predetermined threshold value (36) for the speed variance (30).
