Description

The invention relates to a method for operating a motor vehicle. The invention further relates to a device for operating a motor vehicle.

State of the art

Known are driver assistance systems that implement additional electronic devices in motor vehicles to assist the driver in certain driving situations. Often safety aspects, but also an increase in driving comfort are in the foreground. Another aspect is the improvement of a driving economy. Driver assistance systems partially or autonomously intervene in drive, control (e.g., throttle, brake, etc.) or signaling devices of the vehicle, or alert the driver just before or during critical situations through appropriate man-machine interfaces. Currently, most driver assistance systems are designed so that the responsibility remains with the driver and this is not incapacitated.

• - Radar (z.B. für Spurwechselassistent, automatischer Abstandswarner)
• - Lidar (z.B. für Totwinkel-Überwachung, automatischer Abstandswarner, Abstandsregelung, Pre-Crash und Pre-Brake)
• - Kamera (z.B. für Spurverlassenswarnung, Verkehrszeichenerkennung, Spurwechselassistent, Totwinkelüberwachung, Notbremssystem zum Fußgängerschutz)

For use in driver assistance systems, various types of environment sensors are known, including, for example:

Description of embodiments

In the following, the term automated motor vehicle is used interchangeably in the meanings partially automated motor vehicle, autonomous motor vehicle and partially autonomous motor vehicle. A central idea of the invention is to provide a method and a device for operating a motor vehicle, in particular for enabling an improved, safe overtaking process of the motor vehicle.

The following is based on 1 explains a basic operation of the proposed method.

One recognizes in 1a a motor vehicle 1 on a right lane of a carriageway F in right-hand traffic. The car 1 is equipped with environmental sensors, for example in the form of ultrasound, radar, lidar, mono or stereo camera, lane detection device, etc., with the particular a front and rear environment of the motor vehicle 1 is detected. In this case, at least one of said sensors is both in the front and in the rear of the motor vehicle 1 arranged.

In 1b it can be seen that there is a motor vehicle from behind 2 to the motor vehicle 1 approaches.

1c shows that the motor vehicle coming from behind 2 to overtake the motor vehicle 1 has set, wherein on the opposite lane of the motor vehicle 1 , ie on the lane of the overtaking motor vehicle 2 another motor vehicle 3 accommodates.

1d shows that the overtaking vehicle 2 accelerates to the motor vehicle 1 to overtake. However, the motor vehicle comes 3 getting closer in the oncoming lane.

1e shows that the overtaking vehicle 2 with the motor vehicle 1 is at the same height. The car 1 determines a speed and / or an acceleration of the overtaking motor vehicle 2 and also a distance and a speed of the oncoming motor vehicle 3 , By means of a motor vehicle 1 arranged detection device 20 is determined that at a further unchanged speed of the motor vehicle 1 the overtaking process by the overtaking motor vehicle 2 not successful or accident-free or not without a high risk potential for motor vehicles 1 . 2 . 3 can be stopped. As a consequence, in 1e the speed of the motor vehicle 1 reduces and it becomes the trajectory of the motor vehicle 1 as far as possible shifted to the right, so for the overtaking motor vehicle 2 a maximum possible space on the carriageway F is provided.

In 1g can be seen that thereby the overtaking vehicle 2 could finish the overtaking process successfully.

In 1h is indicated that the motor vehicle 1 resumed normal operation.

As a result, this advantageously makes it possible for a potentially risky passing process to be carried out by means of the operating behavior of the motor vehicle influenced by the method 1 could be completed successfully and safely.

2 shows a block diagram of an embodiment of the proposed device 100 for operating a motor vehicle 1 ,

One recognizes a detection direction 10 for detecting an environment of the motor vehicle 1 , in particular an environment in front of and behind the motor vehicle 1 , The detection device 10 can be used as a radar device, an ultrasound device, a lidar device, a camera, etc., each in the front and rear of the motor vehicle 1 is arranged to be formed.

The detection device 10 is functional with a detection device 20 in conjunction, which is an evaluation of the detection device 10 collected environmental data. In this way, for example, a speed and / or an acceleration of the overtaking vehicle 2 be determined. Furthermore, with determination device 20 whether to be determined by the detection device 10 ascertained data of the overtaking process of the overtaking motor vehicle 2 is possible.

In the event that this is not the case, may be provided by a controller 30 a suitable intervention in the operation of the motor vehicle 1 be made. This can be done for example by means of an optical and / or acoustic signaling of the dangerous condition. As a result, in particular, a driver of a manually controlled motor vehicle 1 informed about the dangerous situation, so that this appropriate driving maneuvers can make the most secure completion of the overtaking process.

Alternatively or additionally, an intervention in a driving operation of the motor vehicle 1 in the form of brakes and / or steering, so that the motor vehicle 1 thereby suitably reduces its speed and / or drives as far as possible right on the right lane edge.

Advantageously, the proposed method can be configured by means of a human-machine interface (English: human machine interface, not shown), for example when entering the motor vehicle 1 or enable / disable at a later time. This allows an adjustment of an operation of the proposed method via the man-machine interface. In this way, for example, a functionality of the method when entering the motor vehicle 1 be activated / deactivated. Furthermore, for example, thus by a user of the motor vehicle 1 determine which actions of the proposed method the motor vehicle 1 when detecting a dangerous overtaking maneuver should perform.

3 shows a basic sequence of a method for operating a motor vehicle.

In one step 200 becomes a detection of an environment of the motor vehicle 1 carried out by the motor vehicle 1 a traffic situation in front of the motor vehicle 1 and a beginning overtaking maneuver of the motor vehicle 1 by a passing vehicle 2 is recognized.

In one step 210 is a determination of speed and / or acceleration of the overtaking motor vehicle 2 by the motor vehicle 1 carried out.

In one step 220 will operate the motor vehicle 1 depending on the determined speed and / or acceleration of the overtaking motor vehicle 2 and the detected traffic situation in front of the motor vehicle 1 carried out such that the overtaking motor vehicle 2 can finish the overtaking maneuver.

As a result, the proposed method can advantageously increase a safety level in traffic and provide a homogeneous traffic flow.

Advantageously, the inventive method can be implemented as a software, for example, on the device 100 expires. A simple adaptability of the method is supported in this way.

In summary, the present invention provides a method and an apparatus for producing safe driving situations, which may be designed, for example, as a driver assistance system. Due to existing sensor systems, the proposed method can be implemented and modified to simple methods.

Although the proposed method has been described above exclusively on the basis of legal traffic, it goes without saying that the proposed method can also be used for left-hand traffic, in which case the direction / orientation information mentioned above must be adapted accordingly.

One skilled in the art will suitably modify and / or combine the features of the invention without departing from the gist of the invention.
