SYSTEM FOR CONTROLLING THE DEPLOYMENT OF AN EXTERNAL SAFETY DEVICE

The present invention relates to a vehicle safety system comprising an external safety system for protecting a pedestrian, and a device for activating the external safety system (13, 14)the device being connected to a pre-crash sensor system (10, 11) and an in-crash sensor system(16). The device is arranged to perform an object classification of a first signal (A1) from the pre-crash sensor system (10, 11). The device is further arranged to determine a threshold (T1, T2) for the in-crash sensor system(16) as a function of the object classification; where the device is arranged to set a first threshold(T1)as a function of a first signal (A1) indicating no object detected or an object classified as a pedestrian; and to set a second threshold(T2), higher than the first threshold (T1), as a function of a first signal (A1) indicating an object classified as a non-pedestrian; and that the device is arranged to compare a second signal (A2) from the in-crash sensor system (16) withthe threshold (T1, T2), whereby the external safety system (13, 14)is activated if the set threshold (T1, T2) is exceeded.
