A method for a device for a vehicle is disclosed, wherein the device comprises a key chip. The method comprises obtaining information relating to the release of a key signal or of an immobilizer signal from a central computer via a wireless mobile communication system. The method further comprises providing a control signal to the key chip based on the information relating to the release of the key signal or of the immobilizer signal, wherein the control signal is designed to allow the key chip to generate the key signal or the immobilizer signal. The method further comprises providing the key signal and/or the immobilizer signal, by the key chip, via a wireless communication link to a central locking system and/or an immobilizer system of the vehicle after the control signal is obtained.

An electronic vehicle key and a communication system wherein the cryptographic material stored in the secure memory of the electronic vehicle key is alterable by a command received from a first communication device or a second communication device to provide multiple vehicles flexibly using personal electronic vehicle key without being dependent, during use, on access to an external database.

An actuator for an electric parking brake, EPB, is described. The actuator comprises a motor configured to actuate an actuating member of the EPB, as well as a reception interface configured to receive an enablement code. An enablement code is assigned to the EPB actuator which individualizes the EPB actuator against other EPB actuators. The actuator further comprises an evaluation unit configured to verify the received enablement code on the basis of the enablement code allocated to the EPB actuator and to enable a control of the motor in case of a positively verified enablement code. There is further provided a control device for the EPB actuator, an electric parking brake and a vehicle having the EPB actuator and corresponding operating methods.

A geo-proximity Vehicle Alert and Access System (VAAS) is discussed that has a cloud based server having a GPS-based proximity system to control and track a package exchange process, to speed up a package delivery and pick-up process, and to ensure security for the package exchange process. The cloud based server is configured to receive both current GPS coordinates of a package carrier's vehicle and current GPS coordinates of a target vehicle for at least one of package delivery to the target vehicle and package pick up from the target vehicle. The cloud based server is configured to send to the target vehicle the commands to wake-up an on-board telematics module, to give an alert, to unlock the target vehicle, and to lock the target vehicle after receiving a confirmation of the package exchange process.

The invention relates to a method for transmission of a secure virtual key (VK) from a server (50, S) to a mobile terminal (20, T) capable of communicating with the server (50, S), comprising the steps of: a) reception by the server (50, S) of a certification request from the mobile terminal (20, T), b) provision and downloading on the mobile terminal (20, T), by the server (50, S), of a user application (25), and c) provision of the mobile terminal (20, T), by the server (50, S), with a virtual key (VK), and d) downloading and securing of the virtual key (VK) in a security element (27) of the mobile terminal (20, T), characterised in that said security element is formed by an encrypting software environment (27).

A projection device comprises a light source, a first attenuator and a second attenuator, a first driver, a second driver, a light receiving element, and a controller. The light source emits light. The first attenuator and the second attenuator attenuate intensity of the light from the light source. The first driver drives the first attenuator. The second driver drives the second attenuator. The light receiving element receives the light distributed by the second attenuator. The controller controls the second driver to control the distribution ratio of the light distributed to the light receiving element by the second attenuator according to control of transmissivity of light at the first attenuator by the first driver.

The present invention relates to a system and method for preventing unauthorized access to a vehicle when setting up a controlled radio interference in specified frequency ranges and is designed to prevent an attacker from obtaining unauthorized access to the vehicle access control system. The system for preventing unauthorized access to the vehicle contains a key fob, a radio receiver of the vehicle and a device for setting radio interference installed inside the vehicle. The key fob contains a radio transmitter and is made with the ability to transmit data to a radio receiver in encoded form. The device for setting up radio interference is made with the possibility of installing radio interference in the frequency range of the data transmission channel between the key fob and the radon receiver of the vehicle. The technical result increases the safety of the vehicle from unauthorized access and theft, due to the provision of additional radar interference.

An access system for a vehicle includes a receiver and an access module. The receiver is configured to receive a signal transmitted from a portable access device to the vehicle. The access module is configured to: generate a differentiated signal based on the received signal; up-sample the differentiated signal to generate a first up-sampled signal; obtain or generate an expected signal; up-sample the expected signal to generate a second up-sampled signal; cross-correlate the first up-sampled signal and the second up-sampled signal to generate a cross-correlation signal; based on the cross-correlation signal, determine a phase difference between the first up-sampled signal and the second up-sampled signal; determine a round trip time of the signal received by the receiver; and permit access to the vehicle based on the round trip time.

An anti-fraud method for use in an in-vehicle network system including a plurality of electronic control units that exchange data frames, each having added thereto a message authentication code (MAC), via at least one bus includes: receiving a data frame transmitted on the bus; generating a first MAC by using a MAC key and a value of a counter that counts the number of times a data frame having added thereto a MAC is transmitted; in a case where the verification has failed, (i) generating as second MAC by using an old MAC key; (ii) re-verifying that the received data frame has added thereto the generated second MAC; transmitting, in a case where the re-verification has succeeded, via the bus a key-update frame indicating a request for updating the MAC key; and updating the MAC key in response to the transmission of the key-update frame.

A Bluetooth enabled Smartphone may be used for both access control and start authorization in a secure and safe way, and embodiments are backward-compatible with conventional vehicle access and start systems. A smart phone acts as an intermediary authorization device to a code generator which effectively resembles a car key that is installed in a vehicle. A Bluetooth transceiver and the code generator—and, optionally, for the retrofit solution, an RF/LF transceiver—are added to the vehicle. The Bluetooth transceiver communicates with the smart phone. The code generator communicates with electronic control units in the vehicle that control access, immobilization, and engine start. The communication may happen via a wired connection or, in the case of the retrofit solution, via an RF/LF transceiver that mimics an additional car key programmed to the vehicle.
