The process of developing new functions and software for powertrain embedded control units (ECUs) is undergoing a sea change. One of the reasons is the pressure to meet regulatory requirements (e.g. emissions, fuel economy) in addition to managing the normal growth in software complexity. Traditionally, the vehicle manufacturer (OEM) would write new specifications and hand them over to the software supplier (Tier1). This process required a substantial review and testing process at the OEM to ensure that the requirements were interpreted and implemented as indented. Today, a number of parties are involved in creating specifications (including the software supplier and 3rd party engineering companies), thus making the verification task even more complex.

While model-based design improves several control algorithm validation steps, the AUTOSAR methodology describes a top-down configuration approach for series production of ECU networks. This paper shows how model-based control-algorithm validation can be interleaved with the AUTOSAR configuration approach. This comprises the integration of a control algorithm to atomic software components as well as a virtual integration of composition components. Last but not least, a survey of resource-analysis techniques for RTE-based ECUs is presented.
