Continental developing digital vehicle keys for intelligent door
Continental says it has expanded its Smart Access solution for convenient vehicle access via smartphone. With the new emergency unlocking solution, users can reportedly gain access to their vehicle digitally, even if the car battery is dead, 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. The new vehicle access technology will be valuable for automated driving and mobility solutions such as car-sharing and fleet services.
"The intelligent door is a milestone in access technology. For the first time, we can offer users a complete package for hands-free and digital operation, from unlocking the car and opening the door to starting the engine. With it, we are enabling an even more convenient and secure driving experience for drivers and offering more design freedom to manufacturers," said Michael Crane, head of Body & Security for Continental in North America.
The emergency unlocking technology operates using buffered energy from the door control unit, which will allow the door to be unlocked once more. The system is activated via near field communication (NFC) technology. An NFC device like a smartphone transmits the signal following a successful security check and automatically triggers the unlocking process for the door.
Continental has integrated an assistant function into the intelligent door. Electronically controlled doors enable hands-free operation. Security and control algorithms ensure that the vehicle door can be opened and closed securely and easily.
Smart Access enables convenient vehicle access via a smartphone. The system centers on a virtual key, which is saved to a mobile device. This key consists of what the company says is a tamper-proof data record and can only gain access after a successful one-time authentication by the back end, which sends it to the smartphone via a wireless interface. As a result, communication only takes place between the smartphone and vehicle.
The system uses multiple Bluetooth Low Energy or NFC transceiver modules located in the vehicle to enable the authorized smartphone to be located from both the inside and outside. As soon as an authorized virtual key is detected, the system issues permission to open the vehicle and start the engine.
