The networking of vehicles with external systems or devices (e.g. mobile phones) is one of the quickest growing areas in the automotive sector. Our customer wants to exploit and expand on the significant potential provided by this trend. EXXETA made a valuable contribution towards realizing the networking of drivers and vehicles as well as the linking of various systems for customer and vehicle data, in order to closely connect cars, customers and manufacturers.

In­iti­al si­tua­ti­on and chal­len­ge

When the pro­ject was star­ted, the first Con­nec­ted Car so­lu­ti­ons were al­re­a­dy avail­able on the mar­ket. In or­der to take over a lea­ding role in this gro­wing sec­tor, the ob­jec­tive was to de­ve­lop a high qua­li­ty tech­ni­cal so­lu­ti­on wi­t­hin a short pe­ri­od of time. The chal­len­ge here re­la­ted to the he­te­ro­ge­neous and de­cen­tra­li­zed sys­tem land­scape and also the lack of any si­gni­fi­cant tech­ni­cal net­wor­king of the cust­o­m­er, car and ma­nu­fac­tu­rer. Ano­ther de­man­ding chal­len­ge when fin­ding a so­lu­ti­on was the re­qui­re­ment for glo­bal, de­cen­tra­li­zed and asyn­chro­nous com­mu­ni­ca­ti­on incl. off­line avail­a­bi­li­ty of po­ten­ti­al ser­vices in fu­ture.


Conception of use cases
De­ve­lop­ment and ve­ri­fi­ca­ti­on of the prac­tica­li­ty of a use case in the con­text of the con­nec­ted car.

Back-end integration
The de­ve­lop­ment of an in­te­gra­ti­on plat­form in a com­pre­hen­si­ve, he­te­ro­ge­neous sys­tem en­vi­ron­ment al­lows for the con­nec­tion of ve­hi­cle, ma­nu­fac­tu­rer, car work­shop, car dea­ler and cust­o­m­er. Data that is collec­ted by the car its­elf using an ar­ray of sen­sors is sent to the ba­ckend whe­re it is pro­ces­sed by dif­fe­rent sys­tems. This in­clu­des data about the car’s oil le­vel, tire pres­su­re and the con­di­ti­on of the bra­kes. The gathe­red in­for­ma­ti­on ser­ves as a ba­sis for the crea­ti­on of va­lue-ad­ded, per­so­na­li­zed ser­vices.

Mobile service platform
To al­low fi­nal cust­o­m­ers the ent­ry into the world of con­nec­ted cars, a cust­o­m­er por­tal was de­si­gned and im­ple­men­ted and se­veral con­nec­ted car ser­vices were in­te­gra­ted. Using a per­so­na­li­zed log­in, the cust­o­m­er has ac­cess to in­for­ma­ti­on about him­s­elf, the car and the car dea­ler at all times. Ad­di­tio­nal­ly, live data from the ve­hi­cle can be mo­ni­to­red and per­so­na­li­zed ser­vices can be used.


In or­der to deal with the nee­ds of the sta­ke­hol­der in a fle­xi­ble man­ner whi­le at the same time iro­n­ing out any un­cle­ar mat­ters in the tech­ni­cal de­sign, we de­ci­ded to uti­li­ze an agi­le pro­ject pro­ce­du­re. Thanks to the in­tel­li­gent lin­king of dif­fe­rent agi­le pro­ce­du­res, an in­iti­al re­cor­ding of re­qui­re­ments was pos­si­ble at a very ear­ly sta­ge, which enab­led the di­men­si­ons of the sub­se­quent ap­p­li­ca­ti­on to be as­ses­sed. EXXETA sup­por­ted the cust­o­m­er with the de­fi­ni­ti­on of the tar­get ar­chi­tec­tu­re, with Re­qui­re­ments En­gi­nee­ring, soft­ware de­ve­lop­ment and ap­p­li­ca­ti­on tes­ting. Ad­di­tio­nal­ly, EXXETA as­su­med re­s­pon­si­bi­li­ty for the in­te­gra­ti­on of he­te­ro­ge­neous sa­tel­li­te sys­tems using the Web­S­phe­re Mes­sa­ge Bro­ker.

Cust­o­m­er be­ne­fits

Thanks to the suc­cess­ful com­ple­ti­on of the pro­ject, the cust­o­m­er was able to take over a lea­ding role in the Con­nec­ted Car mar­ket. The pro­ject enab­led the net­wor­king of cars, cust­o­m­ers and ma­nu­fac­tu­rer as well as sim­pli­fied com­mu­ni­ca­ti­on bet­ween sys­tems. Our cust­o­m­er now has ac­cess to new pos­si­bi­li­ties for cust­o­m­er re­ten­ti­on and star­ting points for fur­ther com­mu­ni­ca­ti­on and in­ter­ac­tion with its cust­o­m­ers, even af­ter a car has been purcha­sed. Im­pro­ved cust­o­m­er sup­port with ad­di­tio­nal func­tions now enables the ma­nu­fac­tu­rer to pro­vi­de in­for­ma­ti­on proac­tive­ly in re­la­ti­on to up­co­m­ing ve­hi­cle ser­vices.
