The method involves attributing, during an allocation, a set of sub-radio frequency channels in a frequency band so that each operating function of a hands-free access and/or cranking system can be assigned to at least a sub-radio frequency channel. The at...

The circuit has an output terminal and an input terminal (1) at which a supply voltage is applied by a battery of a vehicle. A supply circuit is connected to ground. A voltage transformer is connected between an input terminal (Se) of the transformer and t...

The assembly has a badge (14) movable from a longitudinal level in a tunnel (24) from a stable position towards an instable position for activating a start switch (40) and for stopping an engine. The switch is activated by the badge through a latch of the ...

The process involves transmitting a code with two successive sequences of definite distinct powers to a portable device. The device receives a signal with an indication representing the extraction of low power sequences. The device emits the signal to a fi...

The anti-theft system comprises a motor mounted to turn a rotor, and a locking bolt (20) for the vehicle steering column. A cam (22) couples the angular rotation of the rotor (14) to the translational movement of the bolt. A main cam follower (24) presses ...

The car door remote control locking mechanism has two antennas (3,4) on the car (1) to detect an identifying badge (2). The field vector of each signal is used to identify the badge. Coherence is verified between the field vectors and the access plate. Onl...
