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 A host vehicle 2 equipped with the driver assistance system according to the invention is shown on a road 1 and an external vehicle 3 traveling on the same lane 1 ′ of the road 1 . The host vehicle 2 approaches the external vehicle 3 from behind. The task of the driver assistance system is to prevent a collision with an external vehicle 3 .

[0027] For this, as in figure 2 As can be seen in the block diagram of , the driver assistance system includes a surrounding environment sensor 4, such as a camera, a radar sensor or a camera or sensor array for monitoring the surrounding environment of the vehicle 2, and a processing unit 5, usually a microcomputer, configured to Environmental sensor 4 data to identify objects, such as external vehicles 3 in the traffic environment of the vehicle 2, measure the distance between the object and the vehicle 2 and the rate of change of the distance, when based on the current distance of the object and its When the calcula...

Abstract

The invention relates to a driver assistance system for collision avoidance, which has a surroundings sensor (4) for detecting the traffic environment (1) of a vehicle (2) and for determining whether the traffic environment is dangerous and for A processing unit (5) planning a route (15, 15') for a vehicle (2) avoiding said hazard or at least reducing said hazard. The processing unit (5) is also configured to predict possible control interventions by the driver in response to the hazard and to select a route (15) such that the route is compatible with the control interventions.

Description

technical field [0001] The invention relates to a driver assistance system for collision avoidance. Background technique [0002] Such a driver assistance system is known from DE 10 2011 054 344 A1, which is able to provide a combined braking and steering maneuver (Brems-und ) to avoid collisions. [0003] Such a driver assistance system is perfectly capable of finding an appropriate evasive route in a dangerous situation faster and safer than a human driver, and in fully autonomous driving, driving such an evasive route may be the best option, even if it involves Braking and directional changes more severe than the driver is prepared to maneuver or is able to maneuver. However, a problematic situation in manual driving is when the driver assistance system takes over control of the vehicle in a critical situation and steers the maneuver, which the driver has not anticipated. An incomplete control takeover in which the driver and the assistance system simultaneously act o...
