Abstract
A system and method are provided for vehicle passenger classification. The system may include a plurality of weight sensors installed under a seat frame to support a load of a vehicle seat, a single dummy sensor installed under the seat frame to support the load of the vehicle seat along with the plurality of weight sensors, and a passenger classification logic unit for classifying a passenger value obtained by summing sensor values of the plurality of weight sensors as either class 1 or class 2 by comparing the passenger value with a first reference and a second reference.
Claims17
A vehicle passenger classification system, comprising:
- a plurality of weight sensors installed under a seat frame to support a load of a vehicle seat;
- a single dummy sensor installed under the seat frame to support the load of the vehicle seat along with the plurality of weight sensors;
- and
- a passenger classification logic unit for classifying a passenger as either a first class or a second class by comparing a total passenger value Wtotal obtained by summing sensor values of the plurality of weight sensors with a first reference and a second reference.
A vehicle passenger classification method, comprising the steps of:
- receiving sensor values from weight sensors installed under a seat frame so as to support load of a vehicle seat;
- classifying a passenger as either a first class or a second class by comparing a total passenger value Wtotal, obtained by summing the sensor values of the weight sensors together, with a first reference and a second reference;
- if the passenger value Wtotal is greater than the first reference and less than the second reference, determining a sensor value of a single dummy sensor, installed under the seat frame and configured to support the load of the seat along with the weight sensors, from the sensor values of the weight sensors, and modifying the total passenger value Wtotal by adding the sensor value of the dummy sensor to a sum of the sensor values of the weight sensors;
- and
- classifying the passenger as either the first class or the second class by comparing the modified total passenger value Wtotal′ with the first reference and the second reference.
