[0014] The drawings include FIGS. 1 to 3. [Figure 1] FIG. 1 is a plan view illustrating a state in which a motorcycle equipped with a distance control system and / or a speed control system is following a preceding passenger vehicle as a target when the motorcycle is traveling on a straight road. [Figure 2] FIG. 1 is a plan view of a motorcycle being guided by a distance control system and / or a speed control system behind a leading vehicle while negotiating a tight curve. [Figure 3] FIG. 1 is a plan view illustrating multiple motorcycles following each other on a mountain pass having multiple hairpin or sharp curves. DETAILED DESCRIPTION OF THE INVENTION

[0015] When a motorcycle is following another road user on a curved section of road, such as a mountain pass, the radar system may lose sight of the target, and distance control and / or speed control may no longer be possible. The target may suddenly disappear from the detection range of the peripheral sensor devices of the distance control and / or speed control functions. This may occur, for example, due to a sharp bend or a strong curvature of the road.

[0016] Moreover, in such situations, the distance control and / or speed control functions may cause the motorcycle to accelerate unintentionally, depending on the circumstances. To prevent such situations, the data and time of the inertial sensor device can be used to detect dynamic cornering, such as that occurring on mountain passes.

[0017] Via the number of turns or complete maneuvers within a certain time period, the probability that there are still further maneuvers on the road can be calculated. If this probability reaches a predetermined limit, a warning can be issued, for example an optical display can be displayed with advice to the driver to switch off the distance control system and / or speed control system and take full control of the vehicle again.

[0018] The quantities introduced in the detection of the probability include, for example, -Yaw rate of the motorcycle, - the swaying or rolling rate of the motorcycle; - the swaying or rolling angle of the motorcycle, - time intervals between turning points, can include:

[0019] To determine the radius of curvature while driving, the yaw rate during driving may be integrated over time. If this integral value moves around a zero position, it can be assumed that the vehicle is driving straight ahead. However, if the yaw rate deviates from the zero position in a specific direction for a relatively long period of time, it can be assumed that the vehicle is driving on a curve. At the point of deviation, calculation of the curve angle using the yaw rate begins. If the curve is negotiated within a specific time and a specific rolling angle is reached at the same time, it can be assumed that the vehicle is driving on a sharp curve or hairpin curve. If a new sharp curve is detected in a completely different direction within a short time, it can be assumed with a high probability that the vehicle is driving on a mountain pass. If this probability increases and reaches a certain limit value, the driver is requested to turn off the following distance control system and / or the speed control system. The limit value can be parameterized.

[0020] 1 shows a plan view of a motorcycle 12 equipped with a distance control system and / or a speed control system traveling on a road 11, following a preceding passenger car 13 as a target. The roughly club-shaped area 14 represents the detection range of the radar sensor device of the distance control system and / or speed control system equipped on the motorcycle, and the radar sensor device monitors the area in front of the motorcycle. The road 11 is straight, and the passenger car 13 is located in the center of the radar sensor device's detection range 14, so that the motorcycle's distance control system and / or speed control system can operate reliably.

[0021] In Figure 2, the road 21 has a sharp left curve, so that the leading vehicle 23 is no longer within the club-shaped detection range 24 of the radar sensor device of the motorcycle 22. Therefore, the motorcycle's distance control system and / or speed control system no longer detects the target.

[0022] FIG. 3 shows a plan view of a trailing group of motorcycles 32, 33, 34, 35, 36, and 37 on a mountain pass 31 with multiple hairpin or sharp curves. On mountain passes or serpentine roads, it is common for a leading vehicle to disappear from the radar sensor range of the distance control system and / or speed control system only to reappear shortly thereafter. It may be safer for the driver to consciously deactivate the distance control system and / or speed control system on such serpentine roads in order to consciously assume full control of the vehicle. A warning and request to the driver to turn off the distance control system and / or speed control system, which has detected the presence of a serpentine road with a high probability, is appropriate for this purpose. Once the serpentine road has been traversed, the driver can acknowledge this and then manually reactivate the distance control system and / or speed control system. [Explanation of symbols]
