The invention relates to a presence detection method (100) implemented inside a motor vehicle, which method uses a return pulse signal resulting from the reflection, on a target, of a transmitted pulse signal, the return pulse signal and the transmitted pulse signal each consisting of radiofrequency pulses, the presence detection method (100) comprising the following steps of: a/ generating (101) sampled data (I, Q) relating to the return pulse signal; b/ for each of a plurality of successive time intervals (ΔTj), extracting (102) the sampled data located in the time interval (ΔTj) and relating to sampling times for which the delay at a transmission time of a corresponding pulse of the transmitted pulse signal (SE) is less than a predetermined threshold; c/ for each of the successive time intervals (ΔTj), and using the values extracted in step b/, computing (103) a phase shift value (φ(ΔTj)) between the return pulse signal and the transmitted pulse signal; and then d/ using the phase shift values (φ(ΔTj)) to determine whether a user is present.

METHOD FOR DETERMINING THE SPEED OF ROTATION OF AN INTERNAL COMBUSTION ENGINE
The invention relates to a method for determining the speed of rotation of an engine, comprising the following steps: - successively storing (100) tooth passage times (Δti) in a memory, the number of stored passage times being strictly greater than the number of teeth passing in front of the sensor between a first and a second minimum speed of rotation; - respectively determining the angular position (200) of the engine corresponding to the first minimum speed (Pn-1) and second minimum speed (Pn); - determining the time elapsed (300) between the passing of the first minimum speed and the passing of the second minimum speed; and - determining the speed of rotation (400) of the engine from the angular deviation between the first minimum speed of rotation and the second minimum speed of rotation as well as from the stored times between the first and the second minimum speed.
