Abstract This paper proposes a procedure to improve the design of an automobile crashworthiness using the deceleration pulse in a simplified form as a design variable. A complete vehicle in a full frontal crash was simulated to find its deceleration pulse by finite element method. Based on this deceleration pulse, sled tests were performed, also in a virtual environment. Comparisons between the real deceleration pulse and a simplified pulse were made based on the $ HIC_{15} $ produced. The simplified pulse is developed by dividing the pulse in three phases, each with a constant level of deceleration. Simulations were made to minimize the $ HIC_{15} $ changing parameters in the restraint system and in the deceleration pulse. An expression was found to relate $ HIC_{15} $ and the first phase of the deceleration pulse. A design case using this expression is presented. The benefits of using the pulse as a design variable along with the restraint system are accounted.
