Ultra-wideband technology for keyless vehicle access
Continental is a pioneer of the car access system integration:
We digitalize the access experience for a maximum driver convenience. With our new access systems based on Ultra-Wideband, we enable a handsfree smartphone access with the same level of convenience as with state-of-the-art keys.
Ultra-Wideband
The New Key Generation
- Hands-free access and start
- High performance relay attack defense
- Enhanced smart device localization via UWB
- Precise proximity determination to support secure access and start authentication
- Virtual Key Management
- Enabler for Digital Key Sharing and user centric functions e.g. remote parking (Complete UWB eco-system)
- Full system solution expertise including Connected Car Consortium compliance in all access technologies
Technical Solution
Precise localization is key
- Short-range, high-bandwidth communication based on UWB technology
- Centimeter-precise location (ToF/ Time-Of-Flight) of smart device and secure distance measurement
- Real-time precise positioning calculation (inside / outside vehicle fulfilling Thatcham)
- Advanced algorithm to detect inside-outside location of smartphone
- UWB/ Bluetooth® Low Energy transceivers inside and outside of vehicle
- NFC as backup solution
Child Presence Detection using Ultra-Wideband
Expanding Digital Access Technology by live-saving feature
Child-Presence-Detection function identifies children left-behind inside the vehicle and triggers a warning
- System based on innovative ultra-wideband technology with sensing features
- Interoperability of Continental’s Digital Access Technology (CoSmA) and integrated Child-Presence-Detection
- Child-Presence-Detection enables vehicle manufacturers to meet future safety targets
Continental supplies CoSmA system
With Continental’s smart device-based access solution (CoSmA for short), we offer an access system that turns mobile devices such as smartphones or smartwatches into car keys. The system consists of a central control unit, transceivers featuring ultra-wideband radio technology and intelligent software.
