In today's world, many road users are exposed to the risk of accident. The consequences of the potential crash depend not only on the collision speed, but also on the type of vehicle. The article shows the problems connected with choosing an appropriate collision detection model in the case of a collision of two incompatible vehicles. In addition, directions and values of acceleration of inertia during the crash have been determined and presented. The case study is a collision of a motor car with a combine-harvester in which the problem of incompatibility is particularly noticeable. Simulation calculations were performed using the V-SIM4 code. Experimental verification has demonstrated practical application of a collision detection volumetric model, which best represents the impact of such a vehicle. The article also includes information on how to use the collision detection model in the V-SIM4 code, which may be used by court judges, assessors and investigators, as verification of these collision computers codes for cars is unavailable in the literature. Therefore, the subject of the article is both cognitive and practical.
