Abstract
A method and a device for transitioning a vehicle driving without activated lateral guidance assistance into a driving state having reduced risk of collision consequences in the event of an emergency of the driver, wherein the speed of the vehicle is greater than a threshold speed. The method includes detecting a hands-off situation of the driver in a hands-off phase and outputting a hands-off warning, performing a warning escalation in an escalation phase if there is no response to the hands-off warning, and reducing the vehicle speed to a speed less than the threshold speed in an intervention phase if there is no response in the escalation phase. During the hands-off phase, the escalation phase, and the intervention phase, a returning torque is applied to the steering apparatus of the vehicle if it is detected that the vehicle is leaving the current lane.
