Method for wakening up a driver of a motor vehicle
First Claim
Patent Images
1. A method of waking up a sleeping vehicle driver with a wake-up alarm, the release of which is controlled by threshold values from at least two different detection systems, the method comprising:
- detecting, by a first one of the detection systems, driver inactivity;
detecting, by at least another one of the detection systems, the movement of a vehicle relative to one or more of a lane in which the vehicle is driving and objects near the vehicle;
generating an alarm generated by a device that generates vibrations in a steering wheel of the vehicle when one of a first requirement and a second requirement is fulfilled and separately generating the alarm when the other of the first requirement and the second requirement is fulfilled, the first requirement being that a predetermined first shorter period of time for driver inactivity passes and a predetermined threshold value for the vehicle movement is reached, a second requirement being that only a predetermined longer period of time, which is longer than said shorter period of time, for driver inactivity passes.
