Abstract
An occupant classification system for a vehicle comprises a radio-frequency (RF) transmitter unit, which includes a transmission RF antenna and an RF generator operatively connected to the transmission RF antenna. The RF generator and the transmission RF antenna are configured for generating radio waves at a certain fixed RF frequency in the Very High Frequency (VHF) range or the Ultra High Frequency (UHF) range. During operation of the RF transmitter unit, the generated radio waves propagate from the transmission RF antenna. The occupant classification system further comprises an RF detector for detecting, at the fixed RF frequency, an influence of an occupant on the radio waves propagating from the transmission RF antenna.
