Child Presence Detection: Child Presence Detection fulfils NCAP criteria

News from our OE division: those who wish to receive the highest possible rating in the NCAP (European New Car Assessment Program) assessment in future have to ensure that all their new vehicles in Europe and the USA are equipped with, among other features, a child protection system as standard from 2025 onwards. FORVIA HELLA is now launching such a safety system on the market for the first time worldwide with its "Child Presence Detection" system. The function is based on ultra-wideband (UWB) technology, which is also used in our Smart Car Access system developed for the OE division.

How the Child Presence Detection works

Cars are made of metal and synthetic or leather materials that attract heat and store it within themselves. As a result, the temperature in the passenger compartment can rise quickly and create an unsafe environment for all occupants, especially for children. Babies cannot regulate their body temperature in the same way as adults do and are therefore more susceptible to the effects of heat. The result is that every year children die from heatstroke. A state of affairs that is unacceptable: We have therefore carried out tests with children and trained AI with many different scenarios so that Child Presence Detection is highly reliable in the vehicle interior. Using vital signs such as breathing rate and movement patterns of the vehicle occupants, UWB anchors in the vehicle recognise whether children or infants have been left unattended in the vehicle. If this is the case, the system warns the parent or guardian after just a few seconds by triggering an alarm on the person’s mobile device.

The implementation of the "Child Presence Detection" feature is very straightforward: the UWB anchors of the Smart Car Access system already present in the vehicle can be simply used to implement the Child Presence Detection function. The function can therefore be installed in the latest product generation via a software update without the need for additional hardware, as is the case with other solutions. The advantage: material, logistics and integration costs can all be significantly reduced as can CO2 emissions.

The Child Presence Detection system uses UWB anchors in the vehicle interior to register vital signs.

Hands-free – thanks to the Smart Car Access system and ultra-wideband

With the ultra-wideband technology of the Smart Car Access system, the car can also be opened, closed and the engine started completely hands-free. The integrated UWB technology also protects the vehicle against relay attacks, i.e. the opening of a vehicle by radio extension, thanks to the high-precision time-of-flight measurement.

In addition, further functions for the Smart Car Access system are already being planned, such as solutions to prevent unauthorised entry into the vehicle and new convenience functions, such as hands-free opening of the boot. We are also working together with our partner the Car Connectivity Consortium (CCC), a leading group of automotive and entertainment electronics manufacturers, with a view to improving vehicle access with a standardised digital key system. This alliance is itself key to driving the integration of smart vehicles and mobile technologies, with a focus on standardisation, certification and secure connectivity.
