The Extended Vehicle (ExVe) is primarily based on a digital service provider concept under full control of the OEMOEM – Original Equipment Manufacturer. More. The major aspect is to provide safe and secure third-party access to vehicle data by means of an off-board facility. This is a remote and secure server from where service providers can access the data, rather than directly having access to the (moving) vehicle (in an uncontrolled way).
This off-board facility provides access to vehicle data in accordance with clearly defined technical, data protection and competition rules through various interfaces and means of off-board data storage – thereby reducing safety, security and liability risks.
In order to ensure interoperability across the globe, this means of off-board data access and its interfaces must be standardised. To that end, an ISO standard (20077-1) has been developed, better known as the ‘extended vehicle’ concept.
The ExVe standards are a set ISO standards covering 20077, 20078 and 20080. Basically the 20077 describes general concepts of the Extended Vehicle, 20078 details how to retrieve data elements (“resources” in the ISO standard) in OEMOEM – Original Equipment Manufacturer. More specific numbering, ISO 20080 describes remote diagnostics based on an OEMOEM – Original Equipment Manufacturer. More specific numbering of diagnostics relevant elements like ecus or functions inside ECUs.
The extended vehicle consists of a physical road vehicle with external software and hardware extensions that are developed, implemented and managed by the vehicle manufacturer.
But beware: The vehicle manufacturers, acting here as both service providers and data controllers, maintain full control of the automotive aftermarket. Therfore hindering competition and innovation is possible as they become data monopolists.
