Xandar Kardian - CPD (In vehicle Child Presence Detection System) Demo

Описание: In 2018, 52 children died in hot cars. Since 1998, almost 800 children have died from vehicular heatstroke. It’s not about how many, even one child’s life shouldn’t be harmed this way. Governments and Insurance Safety boards around the world agree-

The fact of the matter is that presence detection in a vehicle can be extremely challenging to implement.

Pressure sensors:
Seat pressure sensors are currently designed to be triggered with about 50lbs of weight. Some babies will not pass this limitation. Furthermore, heavy bags/equipment can be placed on the seats, which can trigger false alarms.

PIR/motion sensors: As most motion sensors actually work with heat infrared signals, a hot car would render these sensors ineffective. It will also trigger a lot of false alarms from people just passing by the vehicle.

Ultrasonic sensors:
These sensors look for micro-sounds, such as breathing sounds to detect presence. It may work on some situations (quiet parking lot), but if there is any other sounds nearby – loud mufflers, honking sounds, dogs barking sounds, etc., it will also trigger false alarms.

Door sensors:
Some automotive manufacturers have started to implement a “Reminder” system whereby if the rear doors were opened prior to the car being driven, it assumes that a passenger has entered the rear seats. Upon shutting off the engine, a sound and display will alert the driver to check the rear seats. This can become a nuisance over time if you are prone to putting a bag in the rear seat before driving off. And technically, this isn’t really “child presence detection” system.

Lastly, there are other types of radar based solutions out there. The most common one however is using either 60 or 77 Ghz FMCW radars. These radars are not ideal for occupancy detection as it has a tendency to miss detect in certain situations. Furthermore, as blind spot, cross traffic and other ADAS systems uses FMCW radars in the car, interference from these systems can cause other issues.

Xandar Kardian’s patented CPD system uses IR-UWB RADAR to accurately detect all types of presence detection in various situations. It is also designed to ignore people leaning against the car or people walking past the cars while the car is vacant. The video also further describes the use of metallic coated blanket. The system is NOT affected by temperature (hot or cold), sound or light.

CPD systems can be used to detect potential assailants hiding in the car, child/baby left in the vehicle unattended and also small or large pets.
