A method is disclosed for determining whether it is necessary to utilize safety equipment of a vehicle. The method includes detecting an impending impact of an object with a vehicle's windscreen by obtaining data concerning the object from a vehicle-mounted vision sensor, analyzing the data to determine whether the object will impact the windscreen, and activating the safety equipment only if the windscreen impact is imminent.

Method, computer program product and system for utilizing vehicle safety equipment

A method is disclosed for calibrating a sensor cluster located at an inside of a windshield of a motor vehicle and arranged such that the pitch thereof is adjustable. The sensor cluster may include a narrow beam sensor and an imaging sensor, both of which are directed forward of the motor vehicle. An angle gamma (&#x3b3;) between center directions of the narrow beam sensor and the imaging sensor has been pre-calibrated and stored in at least one memory unit. The method may include calibrating at least one of the narrow beam sensor and the imaging sensor with respect to a geometrical travel axis of the vehicle, recording a measure epsilon (&#x3b5;) corresponding to an angle between the center direction of the imaging sensor and a reference provided by a fixed vehicle structural part, and storing the recorded measure epsilon (&#x3b5;) in the at least one memory unit.
