An simplified practical method has been developed to estimate the interactive force based on the vehicle deceleration in CTC (car-to-car) frontal crash. The adequacy and consistency of proposed method was verified by using the principle of conservation of energy. The calculated force-deformation curves revealed that the interactive force reached the maximum designed strength of the small light car based on the ODB test, while the force level was far below the corresponding design limit of the large heavy car. The relatively lower stiffness of the small light car resulted in absorbing a larger share of the total input energy of the system when crashed into the large heavy car. The maximum impact force and the end of crash force to asses CTC crash compatibility can be accurately estimated by the spot-damage model.
