Abstract: Detection device for a steering wheel of a vehicle, said device being configured to detect contact or proximity of a person with or to the steering wheel, comprising sensors, of which there are only three, of which:



a first sensor (21) is intended to be arranged on a left-hand half of a first face of the steering wheel,
a second sensor (22) is intended to be arranged on a right-hand half of said first face of the steering wheel, and
a third sensor (23) is intended to be arranged on a second face opposed to said first face of the steering wheel, and said first face is a rear face of the steering wheel.

Abstract: A method of measuring a user's contact or proximity to a vehicle steering wheel, comprising the steps of measuring the user's contact or proximity to the vehicle steering wheel during a phase of use of the vehicle steering wheel resulting in generating of a measurement signal (SM), storing in a second memory unit at least part of the values of the measurements taken, adjusting the detection threshold (S2M/1M) based on the stored values and/or processing carried out on the stored values.
