Patent Images
1. A method for detecting contact between a control input device of a vehicle and at least one driver or operator of said vehicle, comprising the steps of:
- detecting oscillatory behavior of said control input device using one or more motion sensors;
calculating with a processing unit a frequency spectrum from said oscillatory behavior detected in said detecting step;
determining a contact force based on said frequency spectrum; and
determining whether or not physical contact exists between said control input device and said at least one driver or operator based on said frequency spectrum.

Abstract
A method provides detecting a contact state between at least one driver/operator of a vehicle and a control input device designed to control the vehicle, where a frequency spectrum is calculated from sensors detected movement signals based on which the contact state between the control input device and the driver/operator is determined.
