摘要:
The invention relates to a method for controlling a functionality of a vehicle (10) by means of a user terminal (20), said method comprising the following steps: obtaining information representative of a distance (d) between the user terminal (20) and an identifier (30); and implementing the functionality only if said information indicates that said distance (d) is shorter than a predetermined threshold. The invention also relates to an associated control system.

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 TM 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).

The invention relates to a method of securing access to at least one functionality of a motor vehicle (10) by a user, said user being equipped with a mobile terminal (20) in which is stored a virtual key (VK) for accessing said functionality, said mobile terminal being adapted, when it is accessible, for communicating with a central server (50). According to the invention, the virtual key having a determined duration of validity, there is provided: - before the end of validity of the virtual key, a first step in the course of which the central server automatically updates the virtual key, then - when the mobile terminal is accessible, a second step in the course of which the central server automatically communicates this updated virtual key to the mobile terminal.

The invention relates to an electronics unit (11) to be fit in a vehicle (10) and designed to control a functionality of the vehicle (10) upon receipt of a request from a user terminal (20), characterized in that same comprises: - a memory unit designed to store a counter and data representing a duration; - means for periodically modifying the value of the counter, the period of time being equal to said duration; - control means for controlling said functionality only when the counter is within a given range of values. Also disclosed are a method carried out in an electronics unit of said type, a method for sharing a time frame between a server and an electronics unit, and a method for synchronizing a server and an electronics unit.
