CoSmA – convenient and secure

Ultra-wideband technology for keyless vehicle access.

AUMOVIO 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

The so-called PASE system enables keyless access to the vehicle and starts the engine without you having to hold the key in your hand. The vehicle system automatically recognizes the correct key when you approach and unlocks the vehicle.

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 AUMOVIO’s Digital Access Technology (CoSmA) and integrated Child-Presence-Detection
  • Child Presence Detection enables vehicle manufacturers to meet future safety targets
