Abstract

A system for multimodal detection of objects in a field of vision located in front of or behind a vehicle, wherein a surroundings-sensing process is carried out by a radar sensor, the radar sensor output signal is fed to a radar signal analysis method, and a visual surroundings-sensing process is carried out by a video sensor, the video output signal being fed to a video analysis method. Object determination takes place such that objects detected by the radar signal analysis method are fed for verification to an object confirmation and situation analysis module by an object detected by the video analysis method.

Claims

1-6. -6. (canceled)

7. A system for multimodal detection of objects in a field of vision located in front of and/or behind a vehicle,

wherein a first surroundings-sensing process is carried out by a first sensor, a sensor output signal of the first sensor being fed to a first sensor signal analysis method with an object-locating means, and a further surroundings-sensing process is carried out by a second sensor, a sensor output signal of the second sensor is fed to a second sensor signal analysis method with object-locating means,

wherein objects which have been sensed by the sensors and detected and determined by the sensor signal analysis methods are fed for verification to an object confirmation and situation analysis module, wherein further vehicle information and a lane prediction are taken into account in the verification, and objects which are relevant for the object confirmation and situation analysis module are determined, wherein measures for increasing passive safety are initiated by the relevant objects and driver information when a hazardous situation is detected by a hazard computer.

8. The system according to claim 7,

wherein the first sensor is a radar sensor and the second sensor is a visual sensor, wherein the sensors sense different ranges of an electromagnetic wave spectrum, and the system is integrated into a driver assistance system with a front sensor system.

9. The system as claimed in claim 7,

wherein the first sensor is a radar sensor and the second sensor is a camera.

10. The system according to claim 9,

wherein data flow between the sensors is minimized by preselecting relevant objects in the radar.

11. The system according to claim 9,

wherein the camera is a video camera, and

wherein sensing ranges of the video camera and radar are adapted and the range sensed by the radar is evaluated by the video camera.

12. The system according to claim 7,

wherein a braking strategy with at least 0.3 g with an increase in deceleration just before a stationary state is carried out by safety systems of the vehicle, as a result of which a sensation of emergency braking is generated for a driver of the vehicle.

13. A system for multimodal detection of objects in a field of vision located in front of and/or behind a vehicle, said system comprising:

a first sensor that is configured to carry out a first surroundings-sensing process by generating a sensor output signal,

a second sensor that is configured to carry out a further surroundings-sensing process by generating a sensor output signal, and

a computer that is configured to;

(i) receive the sensor output signals, (ii) analyze objects which have been sensed by the sensors, (iii) determine which objects are relevant, and (iv) initiate measures for increasing passive safety when a hazardous situation is detected.
