Gateway for two-way vehicle communication

Greenwheels is the largest car-sharing corporation in the Netherlands and operates also in Germany.

As part of their Fleet Sharing Platform for Greenwheels, we developed and supported a vehicle communication gateway. The gateway provides a generic interface between a vehicle for car-sharing and renting scenarios and various other business systems.

The gateway communicates with a vehicle over GPRS and occasionally SMS to both send high-level commands as “Open the door”, “Authorize driver”, etc. and receive vital data on the vehicle status as mileage, current state, and position, tank level, etc.

The gateway was implemented for communication with Renault and Volkswagen cars.
