Abstract

In a method for avoiding collisions between motor vehicles the distance between a motor vehicle and an obstacle located in front of it is determined by means of a distance measuring device and an alarm measure is triggered in the case of a reduction in the distance. In addition, the behaviour of the motor vehicle itself in terms of a change in speed is taken into account and the alarm measure is only triggered if there is no drop in the speed of the motor vehicle.

Description

The invention relates to a method according to the Preamble of claim 1.

In such a method, such as from DE 26 42 211 C2 is known, the Approximation Ge speed to another vehicle or obstacle fend determined and to influence or control the Distance used. In particular, the distance should be be automatically reduced if an impermissible type of approach has occurred. The behavior of the force vehicle is only taken into account insofar as it is for the calculation of the approach speed is pulled. However, it is not considered whether the Approximation is caused by the motor vehicle at a steady speed on a standing or significantly slower vehicle drives up or whether that Vehicle reduces its distance while it is already is braked itself. In the latter case, the driver itself already triggered a braking process and its Attention to the traffic situation clearly he increases.

The invention has for its object a method to create the type mentioned, in which a  Warning measure is only triggered if it is absolutely necessary is required.

The invention solves this problem by characterizing the features of claim 1.

Warning is not just like the state of the art nik an automatic speed-slowing measure but also an optical or acoustic warning or other measure to understand the attention Increase the driver's autonomy. In contrast to the stand The technology becomes the behavior of the motor vehicle considered. He approaches the obstacle with unchanged faster speed, should attract his attention be reduced. It is therefore essential to him to be aware of the risk of a collision earlier than in the case where he already has one Has initiated braking and is facing an obstacle approximates. In this case, his attention is against raised above normal driving and he owns in usually even the possibility of a collision avoid. It is then no longer necessary to open it draw attention to the risk of a collision.

The latter of course only applies if and for as long as this is the case is possible without driving. This can be supplemented by the warning measure can only be triggered at a distance that is too small is smaller than a predetermined distance. This given The value of the distance can depend on whether the driving tool user does not change its speed - in In this case, the distance is relatively large - or whether it is its speed actually decreased - in this In this case, the critical distance can be significantly smaller be put -.  

In addition, the own speed of the force can also vehicle used to measure this distance become. The greater the distance, the greater the choice is the airspeed.

In addition, the differential speed, d. H. the speed of approach to the obstacle be taken into account. Taking into account the various to which influencing factors the distance can be measured that an actual Ge there is a risk to the vehicle user. Complementary can also be used in the dimensioning of the critical distance expected to go the path between triggering the warning measure and that of the vehicle user the measure actually taken Collision reduction is covered. this applies of course only if the vehicle user has not slowed down yet.

As a lower limit for triggering the warning measure even if you slow down of the motor vehicle to assume the value of the distance in within the motor vehicle safely and with usual Ver hesitation to stand or put in a situation that can avoid collision with certainty becomes.

In summary, the invention thus results in Possibility to trigger a warning measure only in this case and to increase the attention of the vehicle user if this is due to the vehicle's own behavior user or based on one of the vehicle user traffic situations are not manageable in all consequences tion is required.

Claims (6)

1. A method for avoiding collisions of motor vehicles, in which the distance of a motor vehicle to a preceding obstacle is determined by means of a distance measuring device and when the distance is reduced, a warning measure is triggered, since characterized in that in addition the vehicle's own behavior with regard to a Ge speed change is taken into account and that the warning measure is only triggered if your own speed does not decrease.
2. The method according to claim 1, characterized in that that the warning measure is triggered at a distance that is smaller than a predetermined distance.
3. The method according to claim 2, characterized in that that the given distance from your own speed depend on the motor vehicle.
4. The method according to claim 2 or 3, characterized records that the predetermined distance from the Diffe speed between the obstacle and the own motor vehicle hangs.
5. The method according to any one of claims 1 to 4, characterized characterized that the warning measure only triggered if the specified distance for a given time is undershot.  
6. The method according to any one of claims 1 to 5, characterized characterized in that the warning measure even with a Reduce your own speed only as long is not triggered as this can be done safely.
