1. An occupant classification system for a vehicle comprising:
- a first sensing electrode located in a bottom of a vehicle seat;
a second sensing electrode located in a back of the vehicle seat;
a controller configured to control a supply of a first signal to the first electrode and a second signal to the second electrode; and
a measurement circuit configured to monitor the first sensing electrode and the second sensing electrode and measure a first property of the first signal and a second property of the second signal,wherein the controller is configured todetermine whether an object or an occupant occupies the vehicle based on the monitoring of the second sensing electrode, andclassify a type of the occupant based on the first property of the first signal and the second property of the second signal when the occupant occupies the vehicle seat.

Abstract
An occupant classification system that includes a first sensing electrode located in a bottom of a vehicle seat and a second sensing electrode located in a back of the vehicle seat. The system includes a controller that is configured to control the supply of a first signal to the first electrode and a second signal to the second electrode. A measurement circuit is provided that is configured to measure a first property of the first signal and second property of the second signal. The controller is configured to classify an occupant using the first and second properties.
