Consistent behaviour generation of a predictive advanced driver assistant system

The invention relates to a driver assistance system and method for a vehicle (2), the vehicle comprising at least one sensor means (9), at least one actuating means (32) and a control means (10). The method comprises the steps of - generating a decision signal (14) by a first evaluation of sensor data (38) acquired by the sensor means (9); - generating an activation signal (23) for the actuating means (32) when the decision signal (14) exceeds a signal threshold (15); - stabilizing the activation signal (23) in a temporal manner; - generating a interrupt decision signal (28) based on a second evaluation; - deciding based on the decision interrupt signal (28) if to interrupt stabilizing the activation signal (23); and - interrupting stabilizing the activation signal (23), when it is decided to interrupt stabilizing the activation signal, thus creating a reliable stabilized activation signal (27).
