The proposed pulse was also reviewed with, and concurred by, Dr Harold Bud Mertz, who is a distinguished safety expert from the automotive industry and provides expert consultation to the OCP TECD team. As more information from deceleration pulses of military and heavy truck vehicles becomes available, the design pulse spec will be modified accordingly. The proposed deceleration pulse is a sinusoidal waveform similar to the generic American Automobile Manufacturers Association pulse used in the auto industry, but has a higher peak value of 35g and lasts a lower duration of 62 milliseconds and corresponds to running head-on into a frontal barrier with an initial velocity of 30 mph. In other words, during initial product development, the frontal pulse specification is the common interface goal for the vehicle developer and the subsystem technology providers.
