Description

State of the art

[0001] From DE 10 2019 208 484 A1, a method for driver-independent adjustment of the longitudinal acceleration of a single-track motor vehicle is known, in which: - the vehicle in front of the single-track motor vehicle is detected by means of an environment sensor and defined as the target object; - driving dynamics data of the target object are determined by means of the same or a different environment sensor; - depending on the driving dynamics data, the longitudinal acceleration of the single-track motor vehicle is adjusted; - it is determined whether the target object is still detected by means of the environment sensor; and - in the event that the target object is no longer detected, the speed of the single-track motor vehicle is set to a predetermined value, wherein the speed is brought closer to the predetermined value in such a way that a predetermined acceleration limit is not exceeded.

[0002] The state of the art in this regard is DE 11 2018 001539 T5 and DE 10 2019 101662 A1. Disclosure of the invention

[0003] The invention relates to a method for activating an overtaking assistance function of a single-track motor vehicle by means of a control element of a direction indicator that can be operated by the driver, wherein the single-track motor vehicle additionally has a distance and / or speed control function, in which The duration of operation of the control element is determined, and if the duration of operation exceeds a predetermined threshold, interventions of the distance and / or speed control function are temporarily suppressed during the driver-independent acceleration phase of the overtaking assistance function.

[0004] An advantageous embodiment of the invention is characterized in that the control element is a turn signal lever.

[0005] An advantageous embodiment of the invention is characterized in that the overtaking assistance function, after its activation by the driver, performs a driver-independent acceleration of the motor vehicle during a time interval of predetermined length.

[0006] An advantageous embodiment of the invention is characterized by the fact that that the distance and / or speed control function is based on environmental sensors, that the environmental sensors determine whether the vehicle is on a single- or multi-lane roadway, and that in the case of a single-lane roadway, the overtaking assistance function cannot be activated.

[0007] An advantageous embodiment of the invention is characterized in that the time interval of predetermined length has a value between 1 second and 2 seconds.

[0008] An advantageous embodiment of the invention is characterized in that the single-track motor vehicle is a motorcycle.

[0009] The invention further comprises a device containing means configured for carrying 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.

[0010] The drawing includes Figure 1 .

[0011] In Fig. 1 The basic sequence of one embodiment of the method according to the invention is shown.

[0012] An overtaking assistance function is primarily intended for use on multi-lane roads. This function accelerates the vehicle independently of the driver, thus enabling a more comfortable overtaking maneuver. During the overtaking process, the driver can therefore concentrate better on monitoring the current traffic situation.

[0013] The overtaking assistance function is often a component or sub-function of a distance and / or speed control function. A distance and / or speed control function uses suitable environmental sensors, such as radar or video sensors, to detect the area in front of the vehicle and thereby ensures that the vehicle does not approach a vehicle detected by the environmental sensors too closely or too quickly.

[0014] If a driver on a multi-lane road initiates an overtaking maneuver on a vehicle ahead in the same lane and activates an overtaking assistance function, a situation may arise in which the requested acceleration conflicts with the distance and / or approach speed requirements of the distance and / or speed control function. This function then suppresses the driver-independent acceleration until the vehicle ahead is far enough away.

[0015] In this case, when initiating the overtaking maneuver, the driver would change to the adjacent lane without the requested acceleration, and the requested driver-independent acceleration would only occur after reaching the new lane. This behavior would feel very unnatural to the driver.

[0016] Such a situation can be prevented if interventions by the distance and / or speed control function are suppressed during the acceleration phase of the overtaking assistance function.

[0017] Besides completely suppressing the interventions of the distance and / or speed control function, it is also conceivable to only allow their interventions if there is an immediate risk of collision with the vehicle in front.

[0018] The safety of the overtaking assistance function can be further increased if, for example, the vehicle's surroundings sensors are used to determine whether it is on a single-lane or multi-lane road. If the road is single-lane, it is also conceivable to disable the activation of the overtaking assistance function.

[0019] The basic sequence of an embodiment of the method according to the invention is described in Fig. 1As shown, after starting in block 100, the system determines whether the duration of an actuation of a control element for activating an overtaking assistance function exceeds a predefined threshold. If not, the system returns to block 100. If the threshold is exceeded, interventions of a distance and / or speed control function are then temporarily suppressed in block 102 during the driver-independent acceleration phase of the overtaking assistance function.
