The disclosure relates to a method to lock, unlock and start a vehicle without using a radio key or electronic vehicle key. According to the disclosure, the function of starting the vehicle without actively using the key is blocked when the vehicle is locked. When the vehicle is unlocked in a manner secured against relay station attacks, the possibility exists of starting the vehicle without actively using the key.

Method to lock, unlock and start a vehicle

The disclosure relates to a method and an apparatus to secure a system for passive unlocking of a vehicle system, particularly a vehicle unlocking system, against relay station attacks. The system comprises a vehicle-based device that can send on a first radio frequency and receive on a second radio frequency, and a driver-based device that can receive on the first radio frequency and send on the second radio frequency. The vehicle-based device and/or the driver-based device are also able to receive on a radio frequency that the other device can receive. One of the two devices send at least one ambient noise signal sequence to the other device. The ambient noise signal sequences received by both are compared with one another with cross-correlation. A current situation is deemed safe if the cross-correlation is strong and a phase shift is small.

A computer-implemented method includes determining that an infotainment system has been activated. The method further includes accessing a vehicle network containing at least a unique vehicle identifier. The method additionally includes comparing the unique vehicle identifier to a stored vehicle identifier. The method further includes permitting access to the infotainment system only if the unique vehicle identifier matches the stored vehicle identifier.
