Introduction This document describes 60-64GHz RF system of “child present detection” for in-vehicle occupancy detection. 2. Abbreviations Abbreviation Description FMCW Frequency Modulated Continuous Wave RFIC Radio Frequency Integratied Circuit RF Radio Frequency CPD Child Present Detection CAN Controller Area Network 3. Sensor system overview CPD detects large movements, such as movement of a child's arms, legs, and seat, to small movements of a sleeping newborn's breathing. Since it is a motion sensor, it does not detect stationary objects. The CPD is connected to the car's CAN bus and controlled, and it operates for several minutes when the driver gets off and the vehicle's ignition is turned off. 4. Hardware 4.1. CPD Sensor In hot weather, the temperature inside a parked vehicle can become very high, which is fatal to children left in the vehicle. CPD prevents these accidents by detecting the occupancy of children left behind and alerting the driver. 4.2. RF-Transceiver RFIC uses the FMCW radar method and uses a frequency band of 60~64GHz. 4.3. Data interface The CPD is connected to the CAN bus. It is controlled and communicates with the CAN signal.

System integration and use cases The CPD is installed above the headliner and is not visible from the inside of the vehicle. The CPD is install ed facing the detection area. The installation angle and location of the CPD can be adjusted with a bracket that connects and fixes the sensor to the vehicle, and it depends on the relative position of the sensor and the seat and sensing space inside the vehicle. In a use case, children can sit on a car seat in the rear seat and the distance from the sensor is greater than that of an adult. Figure 3. CPD vehicle interior cover area 6. Warning Statement This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation
