Data from connected vehicles form the basis for a large number of innovative mobility services. Together with Fraunhofer Institute for Experimental Software Engineering (IESE) & CLEPA (European Association of Automotive Suppliers) we have conducted a survey to verify how well our data catalogue meets the current data needs of representative companies in the connected mobility industry, and to prioritise the catalogue’s data items.

Our data catalogue is an essential step towards harmonization of data from different providers and sources comprising 301 data items. All data items are structured systematically and hierarchically into three main categories.

In this way, the catalogue offers a uniform description of all data points currently considered to be relevant for mobility businesses.

Vehicle Information

General static information about specific vehicles, classes of vehicles and their parts and components, repair and maintenance information, price information, logistics data, the registration of a vehicle in fleet & workshop management systems, among other things.

In-Vehicle Data

Refers to data from a specific vehicle at a specific point in time. Data originate from vehicles and are made available on the marketplace via a connectivity solution (e.g., a dongle or a vehicle manufacturer’s backend). 

Process Data

This category holds vehicle-related data items additionally gathered by verticals in the automotive domain to perform their business processes (e.g. the duration of a certain repair activity).

One Study, Many Answers

Which data at which frequency how accurate and in which format does the mobility data market need?

Let’s look which data are needed first

A digital questionnaire was sent to several companies of the automotive aftermarket, in particular to members of CLEPA and other CARUSO partners containing instructions and CARUSO’s vehicle data catalogue.

The companies were asked to provide a priority level (“mandatory”, “nice-tohave”, or “not needed”) for each of the 301 data items of the catalogue. As optional questionnaire items, the companies could list data items they missed in the catalogue, indicate the purpose(s) for which they intend to use vehicle data.

Which data were given the highest priority? “Speed of Vehicle” comes first, followed by “Acceleration of Vehicle” and “Odometer Value”. The companies additionally stated the need for 125 unique new data items.

High demands are placed on update frequency

Requirements on update frequency were provided for 82% of the data items. For 36% of the data, the strictest requested update frequency is less than 1 second (and often significantly less). This cannot be achieved without lowering the transmission frequencies through (pre-)processing in the vehicle.

The key challenge is to make this data available with the high update frequencies requested and needed for the desired use cases.  The full study is available for purchase via: /datastudy/
