Dozens of studies have been conducted on digital transformation, IoT and Big Data in different sectors, and every week another one appears. Most of the large consulting companies and IT services firms have weighed in, as well as the big technology research community.
However, some questions remain unanswered for the automotive market. Which data at which frequency how accurate in which format does the mobility data market need?
Based on the Caruso data catalogue, the Fraunhofer Institute for Experimental Software Engineering IESE and Caruso conducted a unique study under the auspices of CLEPA (European Association of Automotive Suppliers). The common aim was to identify the data needs of players in the mobility services market.
What does the Caruso data catalogue consist of? It covers all data items currently seen as relevant for mobility use cases – regardless of whether these are very common or only available for selected models and makes.
We’ve sent a digital questionnaire to several automotive aftermarket companies, in particular to members of CLEPA and other Caruso partners containing instructions and Caruso’s vehicle data catalogue with 301 items.
The first part of our blogpost series deals with two questions: Which data are needed? What are the requirements for the update frequency?
For each prioritized data item, the participants were asked in addition to state the desired accuracy and the required update data format.
Take a look at the desired accuracy of data first
42% of the data items were given requirements on their accuracy, mainly regarding significant figures, distances, forces, and degrees. The focus was on data items of the category “Vehicle Position, Movement & Surroundings”. This includes location, speed, direction, point in time, surroundings and driving assist information of a vehicle.
Data items are typically already available with the required accuracy, specifying to which decimals a data item should be provided, or in what kind of unit it is requested. However, for monitoring and statistical analyses, historical and aggregated data such as histograms are needed.
High level of agreement on the data format
The participants mostly agreed on the data format for the majority of the data points. The requirements were only different for a total of 10 data points including “Acceleration of Vehicle” (participants expressed the value in m/s² or g0), “GPS Position & Time at Current Value” (value in decimal degrees /degrees /minutes /seconds) and “Time until next Required Oil Change” (due date or number of days remaining).
Our next blogpost will give you a summary of the survey.
