Abstract
A method and a device are described for detecting the contact between hands and a steering wheel, which assures that the driver of a vehicle has his hands on the steering wheel.
Claims24
A method for detecting a contact between hands of a vehicle driver and a steering wheel, comprising:
- generating a first signal having a first frequency, the first frequency being a function of whether the hands are in contact with the steering wheel;
- generating a second signal having a second frequency;
- and
- generating an output signal as a function of the first frequency and the second frequency.
