W3C liability , trademark and permissive document license rules apply. The Vehicle Information Service Specification VISS is a service for accessing vehicle information, signals from sensors on control units within a vehicle's network. The service provides this information in JSON format. The service may reside in the vehicle for applications needing to analyse a high volume of realtime data or on servers in the internet with information already brought off the vehicle. This specification describes a second version of VISS which has been implemented and deployed on production vehicles. It adds major new capabilities and improvements to the earlier version.
