Abstract

Complexity of in-vehicle computer systems and the availability of computerized mechatronics yield a situation where automotive electronic systems are designed by integration. Since the qualities of a modern vehicle are much dependent on the in-vehicle computer system, integration is a major issue which has proved difficult with respect to assessing quality and cost. OEMs of automotive products want leverage over targeted qualities and the cost of scale when purchasing supplier components. In this paper, we present three cases of integration of mechatronic components into vehicle platforms of Volvo Construction Equipment and focus on the integration of embedded computer systems. The study shows problems areas of communicating architecture constraints, evaluation of components in early phases of development, and lacking definitions of responsibilities. Based on the study, we list four recommended practices to avoid the problems found in the cases. The analysis shows that integration of embedded computers should be considered early in development and in order to reduce project risks, the early assessment of computers need be fairly detailed. From the study we also present driving requirements in design of in-vehicle computer systems.
