vorrichtung und verfahren zur klassifizierung einer auf einem fahrzeugsitz sitzenden person

摘要

A method and a device are proposed for classifying a person sitting on a vehicle seat, which are used to combine a weight estimation based on a seat profile of a person, with a further feature, preferably the distance between the ischium tuberosities, in order to carry out a person classification. The weight estimation is further improved by a temperature correction, either a stored characteristic curve or a correction factor being used in light of a temperature value for the temperature correction. The seat mat is divided into area elements for the weight estimation, the weight pressure being ascertained per area element and the weight estimation being carried out from that.
