Embodiment Construction

[0036] figure 1 The principle of operation of a method for switching a vehicle 1 traveling with a deactivated lateral guidance assistance device into a driving state with a reduced risk of collision consequences in an emergency situation for the driver is described in a schematic diagram in which the emergency assistance device and its goal is to reduce the speed of the vehicle 1 to emergency speed in a controlled manner.

[0037] In a first phase P1 , the vehicle 1 is moving on a lane 2 of, for example, a motorway or a motorway-like road, which is delimited by lane markings 3 from adjacent lanes. The speed of the vehicle in this phase is higher than the above-mentioned emergency speed or a predetermined critical speed. The current vehicle speed can be, for example, approximately 150 km / h in the case of a motorway, wherein the preferred emergency speed is 60 km / h. In this phase P1 , the driver is able to drive and the vehicle 1 is moved along the travel path 4 , the vehicle ...

Abstract

The invention relates to 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, wherein the following steps are performed: 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.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for switching a vehicle traveling without activation of a lateral guidance aid into a driving state with reduced risk of collision consequences in an emergency situation for the driver. method, namely emergency assistance, and a corresponding emergency assistance system according to the preamble of claim 8. 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 automated driving functions. This occurs for example in the case of adaptive speed control (Adaptive Cruise Control), lane keeping assistance or lateral guidance assistance (Lane Assist, Heading Control). [0003] However, the driver assistance system hardly functions in the event of a partial or complete shutdown of the driver of the motor vehicle. Such shutdowns ...
