A method for determining the distance between an authentication device carried by a user and a motor vehicle, each including a wireless communication module so as to exchange a data frame, the data frame being modulated by changing the phase of a reference signal. The method includes the following steps of: the vehicle receiving a modulated reference signal, sent by the device, demodulating the received signal in order to extract an in-phase component and a quadrature component therefrom, computing the power value of the signal on the basis of the maximum amplitude value of the in-phase component and of the maximum amplitude value of the quadrature component, and determining the distance between the device and the vehicle on the basis of the computed power value.

A system for controlling an access authorization and/or driving authorization for a vehicle includes at least one mobile communication device and a control unit in the vehicle that receives and checks authorization data sent from the mobile communication device. The mobile communication device has a data carrier for storing the authorization data. The data carrier has at least one protected storage region for the storage of the authorization data. A database server transfers encrypted authorization data to the data carrier for storage in the protected storage region.

Implementations described and claimed provide systems and methods for vehicle inventory management. In one implementation, a security triggering event corresponding to a security of a vehicle inventory fleet is identified. The vehicle inventory fleet includes a plurality of vehicles. A security command is sent to all of the plurality of vehicles over a network in response to the security triggering event. The security command causes all of the plurality of vehicles to lock. A confirmation that the vehicle inventory fleet is secure is received after all of the plurality of vehicles are locked.

The invention relates to a method (100) for remotely controlling at least a first function of a security device (1) of a vehicle (2), wherein a remote control device (10) has a first radio unit (12), whereby a connection to a mobile radio network (4) can be established. According to the invention, the following steps are carried out: a) determining the position of the vehicle (2) b) determining the position of the remote control device (10) c) determining an actual distance (20) between the position of the vehicle (2) and the remote control device (10) d) comparing the actual distance (20) with at least one defined specified distance (21), wherein the first function is activated if the actual distance (20) is less than or equal to the specified distance (21).

The present invention discloses a lock system, comprising a lock assembly that includes a hasp and an interlock mechanism detachably engaging with the hasp. Further included is a latch system that latches the interlock mechanism in a lock position.

The present disclosure relates generally to a vehicle control method of an electronic device, and the electronic device. The electronic device may include a display, a first communication circuit, a second communication circuit, one or more sensors, a memory, and a processor electrically coupled to the display, the first communication circuit, the second communication circuit, the memory, and the one or more sensors. The memory may store at least one instruction, when executed by the processor causes the electronic device to: detect a Received Signal Strength Indicator (RSSI) value of a Radio Frequency (RF) signal received from a vehicle through the first communication circuit, convert the detected RSSI value based on deviation information stored in the memory, and transmit the RF signal including the converted RSSI value to the vehicle through the first communication circuit.

A vehicle control system (VCS) includes external communication interfaces, such as a Bluetooth interface, for communicating with a user communication and control device, such as a smart phone or a tablet. The user is enabled to operate certain features of the vehicle, such as the remote start, power locks/trunk, climate control, and security features, through the smart phone. The VCS may also communicate with a remote server via the user's smartphone, for example, providing telematics data and receiving service reminders For display to the user on the smartphone, the VCS, or a display built into the vehicle. The VCS may be custom installed in the vehicle using, the user's or the installer's smartphone, without a physical connection from the VCS to the smartphone.

The present invention concerns a method (PR) for detecting an identifier (Id) for starting a motor vehicle (V), said motor vehicle comprising a first antenna (A1) and said identifier (Id) comprising a second antenna (A2). The method (PR) is characterised in that it comprises: —transmitting, by said first antenna (A1), a first Bluetooth Low Energy™ signal (Sg1) to said identifier (Id) at a nominal power (P1); —measuring the power (P1′) of said corresponding signal (Sg1′) received by the second antenna (A2) of said identifier (Id); —comparing said measured power (P1′) with a threshold power (Ps), said threshold power (Ps) corresponding to a threshold distance (ds) from said first antenna (A1) that is less than the radius (r1) of a circle (C1) inscribed within the passenger compartment (H) of the motor vehicle (V), said circle (C1) being centred on said first antenna (A1); —authorising the starting of the motor vehicle (V) if the measured power (P1′) is greater than or equal to said threshold power (Ps).

In various embodiments, methods, systems, and vehicles are provided. In certain embodiments, a vehicle includes a sensor and a processor. The sensor is configured to at least facilitate detecting when a user is disposed within the vehicle. The processor is coupled to the sensor, and is configured to at least facilitate: identifying the user; retrieving, from a memory, a sequence of inputs that is associated with the identified user as a trigger for a customized silent alarm feature for the user; monitoring for the sequence of inputs while the user is disposed within the vehicle; and providing instructions for taking an action when the sequence of inputs is detected while the user is disposed within the vehicle.

An anti-theft device 10 is operatively connected to a vehicle drivetrain, downstream of a power plant. To this end, a gear 12 is mounted for rotation together with a driveshaft 13. The device 10 further includes a pivotally mounted locking pawl 17 which is movable relative to the gear 12 between an open position in which a profiled head 18 of the pawl 17 is spaced away from a periphery of the gear 12 such that the gear 12 is permitted to rotate freely together with the driveshaft 13, and a locked position, in which the profiled head 18 of the pawl 17 engages the gear 12 and prevents rotation thereof, thereby locking the driveshaft 13 in position. The device includes an actuator 23 and ECU 22 in a tamper-proof casing 27. The ECU controls engagement of the pawl depending upon a position of a handbrake and ignition switch.
