A thermistor-based system and method for distinguishing between adult and child passengers and, of the child passengers, between those seated in a child restraint system and those seated in a child booster is provided. The disclosed inventive concept includes at least one classification thermistor/temperature sensing device, at least one reference thermistor, an algorithm to compute and classify conditions, and related wiring and hardware. The classification thermistor/temperature sensing device is located within in a seat cushion assembly and a seat back. The temperature sensors are used to detect heat transfer between an object in contact with the cushion through the seat trim and, if applicable, some amount of seat comfort base material. The reference thermistor may be provided to enhance robustness of classification determination. The algorithm computes and classifies conditions based on at least the magnitude and/or the rate of temperature change between the classification sensor and the reference sensor.
