US manual page 31.Actually I found the following (so we all guessed wrong ) and the system / service operates in conjunction with Porsche Connect.
Porsche Connect uses the new Risk Radar service to improve safety. It provides early warnings of road and traffic conditions identified by the navigation system based on anonymized data from specially equipped vehicles. It’s all about making sure every car reaches its destination. The Risk Radar service is only available in certain countries and for specific car models. For detailed information on availability for your vehicle and in your country, please visit www.porsche.com/connect or contact your Porsche partner.
- The Risk Radar service uses swarm intelligence to warn of hazards.
- Detecting hazards
The system collects anonymized data on traffic hazards like fog, hydroplaning, and accidents.- Sending data
The swarm data are compiled, compared with other vehicle data, and analyzed.- Reporting hazards
The system helps prevent accidents by giving visual and acoustic signals when hazards arise.
Not sure but there is a feature called 'Risk Radar' which is one of the Connect services (I don't have it) which perhaps relates to that.An old topic perhaps, but still: on several occations this winter, the PCM has provided warnings about slippery conditions along my route. Warnings have been perhaps a kilometer or so away from my current location, as the car (naturally) expects me to stay on my current route. All in all a useful feature, in my opinion.
But does anyone have more information on what actually triggers the PCM to issue such warnings for a geographic area? I would imagine it takes more that one single VW-group veichle loosing traction along a road, to show this kind of messages to nearby fleet-members...?
NopeYes, I also believe this is the source of the warnings. Makes sense.
Any more knowledge on the actual algoritms behind this function, @W1NGE?
