Digital Access

Introduction

CoSmA is an embedded OEM’s solution offering access to vehicles, using a smart device to lock, unlock and authorize motor start, provide liftgate access and zone functions (e.g. welcome light, approach unlock) – no more need for a physical car key!

Supported by a cloud solution for virtual key management (key creation, delegation and management), CoSmA offers innovative use cases around the car key like shared mobility services, logistics services or vehicle grooming services.

Products for realizing this Functions

Digital Access ECU

The core of the Continental Smartphone based Access (CoSmA) system is the software managing the different devices and functions

Our software is designed in a modular way to be integrated and run on an existing ECU such as Body Control Module, Gateway or Domain Controller, thus reducing system complexity and cost

Optionally an separate Digital Access ECU is available

BLE/UWB Satellite

The BLE or UWB satellite is an essential part of the Digital Access system. It enables the communication with the smart device.

By strategically positioning BLE/UWB satellites in the vehicle, the system is able to localize the smart device in- and outside of the vehicle.

UWB allows for maximum security against “Relay Attack Defense” threats.

NFC Reader

The use of NFC readers allow the system to work not only with smart devices but also passive NFC badges.

Available as ECU integrated variant (for example in a Multi-Function-Smartphone-Terminal, MFST) or as external NFC antenna.

The NFC antenna is typically integrated in the door handle or the A/B pillar.
