Continental has expanded its Smart Access solution for convenient vehicle access via smartphone to offer drivers a complete package of services. With the technology company’s new emergency unlocking solution, users can gain access to their vehicle even if the car battery is flat – and can do so completely digitally, without having to resort to the mechanical emergency key.
In combination with the Continental Smart Access system, the entire door is intelligent, which means that it opens and closes independently. It does so by using buffered energy from the door control unit, which is sufficient to allow the door to be unlocked once more.
This automatic emergency unlocking system is activated by means of NFC technology, such as via a smartphone, which transmits the signal following a successful security check and automatically triggers the unlocking process for the door.
This means more convenience for users, as they no longer need a mechanical key, even for emergencies. It also opens up more design freedom for carmakers, as they no longer have to develop a conventional key with a blade and can dispense entirely with the emergency lock in the door.
It is being claimed that in combination with the automatic door opener, even the entire door handle will become obsolete, which offers more options for the exterior design, whilst simultaneously improving the vehicle’s aerodynamic resistance.
Smart Access enables convenient vehicle access via a smartphone. The system centers on the virtual key, which is saved to a mobile end device. This key, which consists of a tamper-proof data record, gains access only after successful one-time authentication by the back end, which sends it to the smartphone via a wireless interface. Further communication takes place exclusively between the smartphone and the vehicle.
For this purpose, the system uses multiple Bluetooth Low Energy (BLE) or NFC transceiver modules, located in the vehicle, to enable the authorized smartphone to be located both from inside and from outside. As soon as an authorized virtual key is detected, the system issues permission to open the vehicle and start the engine. Therefore, there is no longer any need for a mechanical key.
