Emergency assistance for controlling a vehicle

Abstract

A method and a device for transferring a vehicle travelling with lateral guidance support into a driving state with a reduced risk of the consequences of a collision in the event of the driver experiencing an emergency, wherein the speed of the vehicle is higher than a predefined limiting speed, comprises the following steps: detecting a hands-off situation of the driver, and outputting a hands-off warning in a hands-off phase, and carrying out a warning escalation in an escalation phase if there is no reaction to the hands-off warning, wherein initiation of the escalation phase is prevented if a predefined blocking condition is satisfied.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for switching a vehicle traveling with an activated transverse guidance aid into a driving state with a reduced risk of collision consequences in an emergency situation for the driver, That is emergency assistance, and a corresponding emergency assistance system according to the preamble of claim 7 . Background technique [0002] In the field of active safety of motor vehicles, conventional driver assistance systems are already able to perceive the driving task of the driver of the vehicle and carry out partially automatic or partially autonomous driving functions. This occurs, for example, in adaptive speed control (AdaptiveCruiseControl) or in lane-keeping assist systems (LaneAssistbzw.HeadingControl). [0003] DE 10 2006 052 481 A1 thus discloses a method for operating a motor vehicle with at least one driver assistance system, in which the driver is provided with the possibilit...

AI Technical Summary

Problems solved by technology

[0012] In the case of such an emergency stop in one's own lane on a motorway or a road similar to a motorway, consideration should be given to the traffic behind, where at the usual speed on the motorway due to the Higher relative velocities between the two can result in a collision with a higher energy impact on a stationary vehicle, which can lead to severe crash consequences

In addition, expensive environmental sensors are required in known emergency parking systems

[0013] In the known emergency parking assistance systems, on the one hand the demands on the required complex sensors (in particular to detect the inability to drive) are extremely high and on the other hand the parking process of the vehicle outside the safe parking or rescue lane until it comes to a stop There is a risk of an impact accident with high energy in the case of
