Cloud Server Remotely Checks Vehicle Performance

Hyundai May be First Automaker to Service Vehicles Via the Cloud

Can the cloud play an impor­tant role in the detec­tion and cor­rec­tion of qual­i­ty and ser­vice issues from the instant a car leaves the assem­bly line and there­after?

Hyundai may be the first com­pa­ny to use the telem­at­ics modem in its Blue Link sys­tem to begin the mon­i­tor­ing process from the instant the car comes off the assem­bly line. And, if the cus­tomer approves, there [is more that can be done from] the call cen­ter report on trou­ble codes.

The Hyundai sys­tem already has yield­ed results, and the com­pa­ny does see a num­ber of appeal­ing ways to move ahead, explained Erwin Raphael, Direc­tor of Prod­uct Qual­i­ty and Ser­vice Engi­neer­ing.

Here are some key areas using the cloud serv­er for analy­sis:

Ear­ly warn­ing pro­vid­ed

  • As an exam­ple, the tire pres­sure mon­i­tor­ing sys­tem on a new San­ta Fe was being set for too high a sen­si­tiv­i­ty, so each car com­ing off the line would trig­ger trou­ble codes for the pres­sures in all four tires. The trou­ble codes tied to a spe­cif­ic car line meant Hyundai was able to real­ize that some­thing was wrong at the assem­bly plant and quick­ly exe­cute a fix.
  • At the begin­ning, a cloud-based E-PDI would prob­a­bly be used to alert deal­ers to any issues detect­ed, but as it becomes more robust, it could sup­plant that aspect of the pre-deliv­ery process.
  • One use­ful post-deliv­ery ser­vice oppor­tu­ni­ty would appear to be con­tin­u­ous mon­i­tor­ing of a vehi­cle with an inter­mit­tent prob­lem.

Reflash­ing issues 

One seem­ing­ly sure oppor­tu­ni­ty for the cloud con­nec­tion would be for soft­ware updates—reflashing vehi­cle com­put­ers to the lat­est lev­el of soft­ware, par­tic­u­lar­ly to cor­rect dri­ve­abil­i­ty and safe­ty issues where pos­si­ble.

How­ev­er, this is the tough­est chal­lenge – even if legal con­cerns were over­come with releas­es and remote iden­ti­fi­ca­tion of a viable set­ting (such as engine warmed up, vehi­cle parked, etc.). Some reflash­es are so long that an own­er might have to ded­i­cate hours, and although that’s pos­si­ble with a per­son­al com­put­er, a motorist might become impa­tient.

It is pos­si­ble for a smart charg­ing sys­tem to pro­vide that capa­bil­i­ty and even trans­mit the volt­age data to the cloud serv­er. But to main­tain the volt­age through an entire reflash, the file size would have to be very small. So some reflash­es still would have to go to the car deal­er, even if not all.

The first appli­ca­tions of remote reflash­ing would like­ly be done when a car is in the deal­er shop for oth­er ser­vice. Ver­i­fi­ca­tion often is done by a shop scan tool, so a cloud-to-modem equiv­a­lent is well with­in cur­rent tech­nol­o­gy.
