Problems solved by technology

In this case, although the angular velocities of the preceding vehicle are measured differently starting from zero, the corresponding sideslip of the own vehicle cannot be measured, because the driver does not follow the road and turns, but goes straight first, to change to the left side lane

Embodiment Construction

[0022] FIG. 1 schematically shows a motor vehicle which is equipped with a driver assistance system which fulfills, for example, the function of an ACC system (Adaptive Speed ​​Controller) and the function of a lane change assistant. An angle-resolving radar sensor 12 is provided as the sensor component, which is mounted in front of the vehicle and monitors the front area of ​​the vehicle, and a rear space radar 14 is provided for monitoring the traffic situation behind on the passing lane, as well as An ultrasonic sensor 16 with which, in particular, vehicles in the passing lane can be detected, which are located in the blind spot between the interior rearview mirror, the exterior rearview mirror and the driver's field of view and also within the localization range of the radar sensors 12, 14 outside. The signals of these sensor components are analyzed and processed in an electronic control unit 18. If it has been recognized that the driver has an overtaking intention and is ...

Abstract

The invention relates to a method for recognising an imminent overtake consisting in measuring a distance d with respect to a preceding vehicle (26), in evaluating the relative speed v of said preceding vehicle and in determining the overtake imminence with the aid of an d- and v-dependent function f (d, v). The blinker activation and / or acceleration / deceleration of the related vehicle are advantageously taken into account.

Description

technical background [0001] The invention relates to a method for recognizing an approaching overtaking maneuver. [0002] Cars are increasingly being equipped with driver assistance systems which, by means of suitable sensor systems, for example by means of radar sensors, detect the surroundings of the own vehicle and support the driver while driving and / or warn against danger Condition. An example of such a driver assistance system is the so-called ACC (Adaptive Cruise Control) system, with which the speed of the car is adjusted to a desired speed selected by the driver and, if the car in front is at its own If the vehicle is in a lane, the distance to the vehicle driving ahead is measured by means of a radar sensor and automatically adjusted by adapting the vehicle's own speed. Such a system not only contributes to improving driving comfort, but also contributes to reducing the risk of accidents. If the driver wants to overtake a slower car in front, he can control the A...
