1. A steering wheel of a vehicle, configured with a detection device to detect contact or proximity of a person with the steering wheel, the detection device comprising only three sensors, among which:
a first sensor arranged on a left-hand half of a first face of the steering wheel and to cover at least 45% of a perimeter of the rim or at least 90° of an angular sector defined in a plane normal to an axis of rotation of the steering wheel and centered on the axis of rotation,
a second sensor arranged on a right-hand half of said first face of the steering wheel and to cover at least 45% of a perimeter of the rim or at least 90° of an angular sector defined in the plane normal to an axis of rotation of the steering wheel and centered on the axis of rotation, and
a third sensor arranged on a second face opposed to said first face of the steering wheel and to cover at least 90% of a perimeter of the rim or at least 300° of an angular sector defined in the plane normal to an axis of rotation of the steering wheel and centered on the axis of rotation,
wherein said first face is a rear face of the steering wheel, and
wherein at least one of said sensors has, on a radial cross-section of the steering wheel, a position and/or an included angle that varies depending on a location of said radial cross-section on the steering wheel.
