Abstract

A safety system for a motor vehicle having a sensing arrangement (11) providing sensor signals related to the surrounding environment of the vehicle, at least one safety means (13, 14, 15) for an occupant of the vehicle, and a control means (22) adapted to control the safety means (13, 14, 15) depending on signals from the sensing arrangement (11). The safety system (10) has an environment classifying means (23) adapted to classify the surrounding environment of the vehicle into different predetermined categories on the basis of signals from the sensing arrangement (11), and to adjust the control means (22) depending on the vehicle environment category determined by the environment classifying means (23).

Claims

1. A safety system for a motor vehicle, comprising:

a sensing arrangement providing sensor signals related to the surrounding environment of the vehicle and related to detection of an animal or a pedestrian;

at least one safety means for providing enhancing safety for an occupant of the vehicle;

a control means for controlling the safety means depending on the sensor signals from the sensing arrangement;

an environment classifying means for classifying the surrounding environment of the vehicle into different predetermined categories on the basis of the sensor signals from the sensing arrangement and for adjusting the control means depending on the predetermined category classified by the environment classifying means, wherein the surrounding environment is the environment surrounding both the vehicle and either a road or highway in which the vehicle operates, wherein the environment includes the environment in which the road or highway is located;

wherein, depending on the classified predetermined category, the control means is adjusted with respect to its control of the safety means in the event of the signals being related to the detection of an animal or a pedestrian;

wherein the safety means is adapted to provide an animal or pedestrian warning, and the animal or pedestrian warning is deactivated depending on the predetermined category classified by the environment classifying means;

wherein the environment classifying means is adapted to determine that the surrounding environment is a city environment and the city environment is a predetermined category;

wherein the safety means is adapted to provide an animal warning and the animal warning is completely deactivated if the city environment is determined by the environment classifying means; and

wherein the predetermined category is classified on the basis of yaw rate data provided by a yaw sensor of the sensing arrangement.

2. The safety system according to claim 1, wherein the safety means provides safety-related information to the occupant of a vehicle.

3. The safety system according to claim 1, wherein the sensor arrangement is adapted to provide the sensor signals related to detection of the animal or the pedestrian in front of the vehicle.

4. The safety system according to claim 3, wherein the safety means is adapted to provide an animal warning or the pedestrian warning to the vehicle occupant if the animal or the pedestrian is detected in front of the vehicle.

5. The safety system according to claim 1, wherein the environment classifying means is adapted to determine that the surrounding environment is a rural or non-city environment and the rural or non-city environment is a predetermined category.

6. The safety system according to claim 5, wherein the safety means is adapted to provide an animal warning and the animal warning is activated if the rural or non-city environment is determined by the environment classifying means.

7. The safety system according to claim 1, wherein the environment classifying means is further for performing classification filtering over time by considering a weighted sum of several time consecutive classification results.

8. The safety system according to claim 1, wherein the control means is adjustable to one of a plurality of predetermined states depending on the predetermined categories.

9. The safety system according to claim 1, wherein the predetermined category is classified on the basis of image data provided by an imaging means for imaging of the sensing arrangement.

10. The safety system according to claim 1, wherein the predetermined category is classified on the basis of vehicle data provided by at least one vehicle sensor of the sensing arrangement.

11. The safety system according to claim 1, wherein the predetermined category is classified on the basis of speed data provided by a speed sensor of the sensing arrangement.

12. The safety system according to claim 1, wherein the predetermined category is classified on the basis of a combination of image data provided by an imaging means and vehicle data provided by at least one vehicle sensor of the sensing arrangement.
