A method of pre-crash prediction of the severity of an imminent crash of road vehicles is disclosed using a pre-crash sensor, a computer system coupled with pre-crash vehicle condition signal sources and a vehicle communication system onboard each of two vehicles involved in a crash. The method includes the steps of determining that a collision of the vehicles is imminent, exchanging vehicle crash-related information between the vehicles when an imminent collision is determined, computing crash-defining information onboard each vehicle and predicting onboard each vehicle the severity of the imminent collision whereby occupant protection devices of the vehicles may be deployed in accordance with the predicted severity.
