Automotive standards are created to improve quality, facilitate innovation, increase speed to market but the major motivation is the costs reduction achieved through multiple suppliers solutions and cost sharing among carmakers, Tier-1s and suppliers.
Conformance testing is established to determine whether implementations comply with the requirements of a technical standard. The use of different implementations will lead to the question how interoperable they are. Experiences in in-vehicle networks have shown that it is not a matter of course that devices of different manufacturers work together in diverse environmental conditions. Conformance testing is the solution to this problem for ensuring a level of interoperability of devices from different suppliers in a system environment.
Japanese automotive industry is increasingly interested in applying conformance testing within their qualification processes.
