Road vehicle comprising a powertrain system; an ignition system for the powertrain system comprising in turn a slot integral with the passenger compartment of the road vehicle and configured to receive and accommodate a key for the ignition of the road vehicle; wherein the ignition system comprises a detection system, configured to detect the presence or absence of the key at the slot, and a control unit, which is connected to the detection system and to the powertrain system and is configured to enable the power supply to the powertrain system only when the key is detected at the slot.

A vehicle access system includes a first network device that transmits a first tone signal to a second network device and receives a second tone signal from the second network device. The first or second network device is a portable access device. The system includes a control module that receives tone values from a sniffer device located at the vehicle. The tone values are associated with i) a difference in phase of a tone of the first tone signal between when transmitted to when received at the sniffer device, and ii) a difference in phase of the tone of the second tone signal between when transmitted to when received at the sniffer device. The control module estimates a first distance from the vehicle to the second network device based on the tone values received from the sniffer device and permits access to the vehicle based on the first distance.

A method for connecting a Bluetooth key to a vehicle, a vehicle Bluetooth system, and a Bluetooth key, comprises: when a mobile terminal enters a preset distance range of a vehicle, a Bluetooth master module of the vehicle performs authentication and connection with a Bluetooth key of the mobile terminal according to preset key information (S11); after the Bluetooth master module is successfully connected to the Bluetooth key, the Bluetooth master module generates an original random code and encrypts the original random code to obtain an encrypted random code (S12); the Bluetooth master module sends the original random code to a Bluetooth slave module, and sends the encrypted random code to the Bluetooth key (S13); and the Bluetooth slave module and the Bluetooth key perform bidirectional authentication according to the encrypted random code and the original random code, and when bidirectional authentication succeeds, the connection is established (S14).

An in-vehicle system executes authentication of a mobile device multiple times from a parking state until an engine is started. The in-vehicle system operates in an alert mode when a vehicle is parked, and transmits an authentication signal including a strength change signal. When the in-vehicle system operates in an alert cancellation mode, the mobile device returns a response signal only when there is a change in the strength of the received authentication signal. When the in-vehicle system succeeds in authentication of the mobile device in an authentication process in the alert mode, the in-vehicle system shifts to the alert cancellation mode. When the in-vehicle system operates in the alert cancellation mode, the mobile device returns the response signal irrespective of whether there is the change in the strength of the received authentication signal.

A wireless communication system includes: an in-vehicle unit mounted on a vehicle and capable of wirelessly transmitting an access signal when an operation unit is operated; a portable device capable of wirelessly transmitting a vehicle-specific authentication code on a condition that the access signal is received; and a determination unit capable of determining whether or not the authentication code is a regular authentication code on a condition that the authentication code is received. Start of a driving source of the vehicle is permitted or running of the vehicle is enabled when the determination unit determines that the authentication code is the regular authentication code, and a security mode in which a function of transmitting the access signal by the in-vehicle unit or a function of transmitting the authentication code by the portable device is stopped can be set by a predetermined setting operation.

The invention relates to a security method (100) for a security system (200) of a vehicle (1) for activating at least one security-related function in the vehicle (1) by means of at least one data transfer (D) between a portable access device (10) and the vehicle (1).

A vehicle ignition system includes an ignition cylinder housing defining an exterior portion, an interior portion and a channel extending at least partially through the interior portion. An ignition cylinder is at least partially received by and adjustable relative to the ignition cylinder housing. The ignition cylinder includes an elongate body defining an exterior portion and an interior portion. A cam member is at least partially received in the channel of the ignition cylinder housing and includes a clutch disposed adjacent to and engaging a portion of the ignition cylinder. A locking mechanism cooperates with the ignition cylinder housing and ignition cylinder includes a locking member having a projection extending therefrom that releasably engages a portion of the ignition cylinder housing when the locking mechanism is placed in the at least one second position to prevent adjustment of the ignition cylinder relative to the ignition cylinder housing.

An electronic key system includes an onboard apparatus and a portable apparatus. The electronic key system establishes wireless communication with a secret key common between the onboard apparatus and the portable apparatus, and authenticates the portable apparatus registered as the portable apparatus of an authorized user. The portable apparatus includes a portable apparatus code transmitter that transmits a portable apparatus code. The onboard apparatus includes an onboard code transmitter that transmits an onboard code. The onboard apparatus further includes a portable apparatus code receiver, and an onboard-side key generation portion. The portable apparatus further includes an onboard code receiver, and a portable-apparatus-side key generation portion.

A terminal device includes a communication device, configured to detect whether a native system of the terminal device includes components for adapting a public protocol of a digital vehicle key, and communicating with a target communication party based on the public protocol in case of absence of at least one of the components in the native system, in which the target communication party is a participant of the public protocol.

The invention relates to a security method (100) for a security system (200) of a vehicle (1) for activating at least one security-related function in the vehicle (1) by means of at least one data transfer (D) between a portable access device (10) and the vehicle (1).
