[0001] The present invention relates to a method and apparatus for activating an overtaking assist function in a single track vehicle. [Background technology]

[0002] Patent document 1 discloses a driver-independent method for adjusting the longitudinal acceleration of a single-track vehicle, in which a peripheral sensor system detects a vehicle ahead of the single-track vehicle and determines it as an object, the same or another peripheral sensor system detects driving dynamics data of the object, the longitudinal acceleration of the single-track vehicle is adjusted depending on the driving dynamics data, the peripheral sensor system detects whether the object is further detected, and if the object is no longer detected, the speed of the single-track vehicle is adjusted to a predetermined value, and the speed is adjusted to a predetermined value so as not to exceed a predetermined acceleration limit value.

[0011] [Figure 1] FIG. 1 illustrates the basic steps of one embodiment of the method according to the invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] The drawings include Figure 1. In Figure 1 the basic steps of one embodiment of the method according to the invention are shown.

[0013] The Overtaking Assistant function is primarily intended for use on multi-lane city streets. To this end, it performs driver-independent acceleration of the vehicle, thereby making the overtaking process more comfortable for the driver, so that during the overtaking process the driver can better concentrate on monitoring the current traffic situation.

[0014] The overtaking assistance function is often a part or sub-function of a distance and / or speed control function, which detects the area in front of the vehicle using a suitable surrounding sensor system, for example a radar or video sensor system, and thereby ensures that the host vehicle does not approach too closely or too fast a preceding vehicle detected by the surrounding sensor system.

[0015] When a driver is in the process of overtaking a vehicle ahead in the same lane on a multi-lane road and activates the overtaking assistance function, a situation may arise in which the required acceleration conflicts with the distance and / or closing speed requirements of the distance and / or speed control function, in which case the function will inhibit driver-independent acceleration until the vehicle ahead is sufficiently far away from the host vehicle. In this case, the driver would move into the adjacent lane to begin the overtaking process without the assistance of a requested acceleration, and only when the driver reaches the new lane would the requested acceleration occur independently of the driver. This behavior would seem very unnatural to the driver.

[0016] This situation can be prevented if the intervention of the distance and / or speed control function is suppressed during the acceleration phase of the overtaking assistance function.

[0017] In addition to completely suppressing the intervention of the distance and / or speed control function, it is also conceivable to allow this function to intervene only if there is an imminent risk of a direct collision with the vehicle ahead.

[0018] The safety of the overtaking assistant function can be further improved if, for example, a surroundings sensor system detects whether the vehicle is on a one-lane or multi-lane street or road. In this case, it is conceivable to prevent the overtaking assistant function from operating.

[0019] The basic steps of one embodiment of the method according to the invention are shown in Figure 1. After starting in block 100, it is detected whether the duration of the actuation of the operating element for activating the overtaking assistance function exceeds a predetermined threshold. If not, the process returns to block 100. If the threshold is exceeded, then in block 102, the intervention of the distance and / or speed control function is temporarily inhibited during the driver-independent acceleration phase of the overtaking assistance function.
