Occupant e.g. adult, detection and classification method for motor vehicle, involves comparing power value to set of predetermined values for determining presence of occupant and classifying occupant based on their weight

摘要

The method involves controlling an actuator such as electric motor, permitting vertical displacements (m1, m2) of a seat (1) with predefined power profile, where the power profile presents a variable characteristics representative of effort applied by the actuator for displacing the seat. The starting of movement of the actuator is detected, and a power value of the characteristics is measured. The measured value is compared to a set of predetermined values for determining the presence of an occupant and classifying the occupant based on their weight. An independent claim is also included for a device for detection and classification of an occupant on vehicle seat.
