System layout and trigger logic for active pedals

摘要

A method and system (12) for determining whether and/or when to activate a safety-related feature (14, 44) of a vehicle (10) in the event of an imminent collision between the vehicle and a foreign object (16). The system includes detecting means (18, 18') for determining the position of the foreign object relative to the vehicle and for determining the relative velocity between the vehicle and the foreign object. A system control unit (20) is arranged to communicate with the detecting means (18, 18') to receive data relating to the position and the relative velocity and, based on at least some of the data, to determine whether and/or when to emit a signal to activate the safety-related feature (14, 44). The system control unit (20) is arranged to dynamically set a discrimination factor dependent on at least some of the data to thereby vary, dependent on at least some of the data, the passage of time from receiving the data to emitting the signal to activate the safety-related feature. <IMAGE>
