A vision system and method for autonomous driving and/or driver assistance in a motor vehicle are presented, comprising an imaging apparatus (11) adapted to capture images (30) from a region surrounding the motor vehicle, a data processing device (14) comprising an object detector (31) adapted to detect and classify objects in the vehicle surrounding by processing images captured by said imaging apparatus (11), and a decision module (32) adapted to estimate a collision probability of a detected object with the motor vehicle, and to make an intervention decision (37) in case a detected object has a non-tolerable collision probability. A critical object classifier (35) is connected to the decision module (33) in a feedback loop (36). The decision module (33) is adapted to identify, among all detected objects, a sub-group of critical objects having a high potential of causing an intervention, and to feed information regarding identified critical objects to the critical object classifier (35). The critical object classifier (35) is adapted to verify the classification of the object detector (31), and to feed back a result of the verification to the decision module (33).

At least one detector (2) for visible and/or IR radiation on board of a vehicle (100) is used to determine if an entity (200) is approaching the vehicle (100). If so, sensors (4) for vibration and/or acceleration are activated. Signals from these sensors (4) are used to determine if a contact between the entity (200) and the vehicle (100) has occurred. The contact may be classified based on these signals. The at least one detector (2) may include a camera (21). At least one camera (5, 21) on board of the vehicle may be used to record image data pertaining to a time-interval about the contact. A warning may be triggered if a contact between the entity (200) and the vehicle (100) is likely.
