Problems solved by technology

However, a problematic situation in manual driving is when driver assistance systems take over control of the vehicle in a critical situation and steer maneuvers, which the driver did not expect
An incomplete control takeover in which the driver and the assistance systems simultaneously act on the directional control and / or speed control of the vehicle and thus possibly interfere with each other is quite disadvantageous

Embodiment Construction

[0026] figure 1 Shown are a host vehicle 2 equipped with a driver assistance system according to the invention on a road 1 and an external vehicle 3 traveling on the same lane 1 ′ of the road 1. The own vehicle 2 approaches the external vehicle 3 from behind. The task of the driver assistance system is to prevent collisions with external vehicles 3.

[0027] For this, as in figure 2 As can be seen in the block diagram, the driver assistance system includes surrounding environment sensors 4, such as cameras, radar sensors, or cameras or sensor arrays that monitor the surrounding environment of the vehicle 2, and includes a processing unit 5, usually a microcomputer, which is configured to rely on the surrounding environment The data of the environmental sensor 4 is used to identify the object, such as the external vehicle 3 in the traffic environment of the own vehicle 2, and measure the distance between the object and the own vehicle 2 and the rate of change of the distance. Whe...

Abstract

A driver assistance system for avoiding collisions includes an environmental sensor(4) for detecting the traffic environment of the vehicle(2) and a processing unit(5) configured to assess the traffic environment(1) as to the likelihood of a danger and plan a route(15,15') avoiding or at least minimizing the danger for the vehicle. The processing unit(5) is further configured to predict a possible control intervention of the driver in reaction to the danger and select a route(15) which is compatible with that control intervention.

Description

Technical field [0001] The present invention relates to a driver assistance system for avoiding collisions. Background technique [0002] Such a driver assistance system is known from DE 10 2011 054 344 A1, which can provide a combined braking and directional control maneuver (Brems-und ) To avoid collisions. [0003] Such a driver assistance system can fully find a suitable avoidance route faster and safer than a human driver in dangerous situations, and in fully automatic driving, driving such an avoidance route may also be the best choice, even if it includes Braking and direction changes more severe than what the driver is prepared to manipulate or can manipulate. However, a problematic situation in manual driving is that the driver assistance system takes over control of the vehicle and turns to maneuver in a critical situation, which the driver does not expect. In which the driver and the auxiliary system simultaneously act on the direction control and / or speed control of ...
