Motor vehicle steering wheel, with grip pressure sensitivity, has a capacitative proximity switch and the metal wheel as an electrode to sound a warning if the driver falls asleep at the wheel

摘要

The motor vehicle steering wheel, sensitive to the pressure applied by the driver's grip, has an assembly with a capacitative proximity switch and an electrode under the steering wheel cladding formed by the metal steering wheel itself. If the grip pressure drops below a threshold, a warning signal is generated.
