Standards Development

Scope

This document defines an API which standardizes the methods for diagnosing HPCs and legacy ECUs, the retrieval of the diagnostic capabilities, and the discovery of the SOVD methods in an extended vehicle. The SOVD API provides a unified access to classic ECUs and HPCs.The SOVD API provides functions such as:— Access to the faults, including reading the fault entries, reading environment data, and deleting fault entries.— Measurements and identifications of all entities.— Execution of routines, I/O controls, and software functions in certain modes or states.— Configuration of a vehicle (e.g., equipment, country, customer demand, variant coding etc.).— Encapsulation of the ExVe manufacturer specific software update strategy (incl. FOTA if available).— Access to logging information of an HPC.With these features SOVD can cover all areas of the vehicle life cycle which includes in particular Engineering (Development), Manufacturing (Production), After Sales (Maintenance and Repair), Legal and Technical inspections, and Vehicle operation (Use).There are several aspects which are not covered by this document, as they are specific to the implementation of an SOVD server, for example:— Prevention and quick reaction to attack vectors like denial of service, zero-day exploits of vulnerabilities, …— Recognition of security incidents— Maintaining the operational safety based on data monitoring— Management of security incidents— Data privacy issues— Load balancing of concurrent requestsThis document considers the extended vehicle as defined in ISO20077 series. This means that the API or its elements can be inside or outside the physical vehicle.
