Abstract:

The optimum temperature control of the Automatic Climate Control (ACC) in the vehicle cabin is dependent on whether or not the thermometer can measure temperatures around occupants. Most in-car temperature sensors are difficult to achieve. To measure the temperature around occupants, this study presents a technique based on ultrasonic temperature sensors using the sampling of the ultrasonic time of flight (TOF). The temperature environment was changed for Measurement. The Kalman filter processed the data for lowering noises and increasing accuracy. The experimental results showed that the ultrasonic temperature sensors could provide accurate temperature measurements, fast response to temperature changes, and non-contact.

Keywords:

automatic climate control (ACC), thermometer, ultrasonic temperature sensor, time of flight (TOF), Kalman filter, non-contact.
