Method and device for assisting a driver of a motor vehicle when the distance and speed control system is deactivated

Description

State of the art

[0001] From DE 10 2020 207 502 A1 a method for operating a single-track or multi-track vehicle with a driver assistance system is known, wherein a speed of the vehicle and a distance of the vehicle to a vehicle traveling ahead are controlled, wherein the speed is controlled within a system-dependent speed range of the driver assistance system using a position of an operating element of the vehicle and is controlled up to an optional target speed selectable within the speed range, wherein a warning signal is provided to a driver of the vehicle before an upper limit of the speed range is exceeded and wherein the distance within the speed range is controlled in a speed-dependent distance buffer range depending on the position. Disclosure of the invention

[0002] The invention relates to a method for assisting a driver of a motor vehicle when the distance and speed control system is deactivated, in which The distance to an object in front of the vehicle is detected by means of a predictive environment sensor system attached to the vehicle and driver information is output depending on the distance and the current speed of the single-track vehicle.

[0003] The environmental sensor system is, in particular, a radar sensor system which is part of a distance and speed control system and influences its control.

[0004] An advantageous embodiment of the invention is characterized in that, depending on the current speed of the motor vehicle, a minimum distance to the object in front of the motor vehicle is determined, and that the driver information is output when the distance falls below the minimum distance. The object is, in particular, the vehicle directly ahead.

[0005] An advantageous embodiment of the invention is characterized in that the driver information is output after the end of the journey.

[0006] The invention is characterized in that the driver information is output when, during the journey, the number of events in which the distance has fallen below the minimum distance has reached or exceeded a predetermined limit value.

[0007] An advantageous embodiment of the invention is characterized in that the driver information includes an indication to increase the distance and / or reduce the speed.

[0008] An advantageous embodiment of the invention is characterized in that the relative speed between the motor vehicle and the object in front of the motor vehicle is additionally detected and, depending thereon, further driver information is output.

[0009] An advantageous embodiment of the invention is characterized in that the further driver information is output when a predetermined number of times a limit value is exceeded at the relative speed during a journey or during a time interval of predetermined duration.

[0010] An advantageous embodiment of the invention is characterized in that the additional driver information includes a recommendation to take a break and / or an indication to react more quickly to slower vehicles ahead.

[0011] An advantageous embodiment of the invention is characterized in that the motor vehicle is a single-track motor vehicle.

[0012] An advantageous embodiment of the invention is characterized in that the single-track motor vehicle is a motorcycle.

[0013] The invention further encompasses a device containing means designed to carry out the methods according to the invention. This is, in particular, a control unit in which the program code for carrying out the methods according to the invention is stored.

[0014] The drawing includes Figure 1 .

[0015] In Fig. 1the basic sequence of an embodiment of the method according to the invention is shown.

[0016] One way to increase the safety of motorcyclists is to continue to use the signals from the sensors of a distance and / or speed control system even when the distance and / or speed control system is deactivated.

[0017] Minimum distances are prescribed in road traffic. These are intended to ensure that, in the event of unexpected traffic obstacles, there is sufficient space and time to prevent a collision or at least mitigate the impact. The minimum distance depends on the speed. In general, the greater the distance required from the vehicle in front, the greater the speed.

[0018] Distance and / or speed control systems usually have an environmental sensor system, e.g. a radar sensor system, which determines the distance and the relative speed to a vehicle ahead or to an object in front of the vehicle.

[0019] Even if the distance and / or speed control system is deactivated, this information can be evaluated and displayed graphically on a display, for example in the instrument cluster.

[0020] If, for example, the minimum distance is frequently exceeded, a driver warning can be displayed in the instrument cluster, prompting the driver to increase the distance. It is also conceivable to display an evaluation of driving behavior while the vehicle is stationary after the journey. This could, for example, be a visual display stating "Distance repeatedly too small" or "Recommendation: Maintain a greater distance for your safety."

[0021] Information on relative speed can also be included. High relative speeds and the associated rapid approach to slower vehicles are an indicator of hectic, risky, or inattentive driving. In this case, a warning message and a recommendation for a break for the driver could also be included in the analysis, for example, combined with the information "Frequently encountering slower vehicles" and "Recommendation: Try to react more quickly to slower vehicles to increase your safety."

[0022] In Fig. 1 the basic sequence of an embodiment of the method according to the invention is shown.

[0023] After starting the method in block 100, the distance to an object in front of the vehicle, in particular a vehicle traveling ahead, is detected in block 101 using a forward-looking environment sensor system mounted on the vehicle. In block 102, this distance is compared with a minimum distance. If the distance is greater than the minimum distance, the system returns to block 101. However, if the distance is less than the minimum distance, driver information is output in block 103, either immediately or after the end of the journey. The method ends in block 104.
