The Convadis Carsharing System – Our solution at a glance
Thanks to almost 30 years of experience in the operational and technical field and the practical know-how gained during this time, we have developed a system that covers all the requirements of daily carsharing business. We are happy to introduce you to the features of our carsharing system in detail.
Full control for every car-sharing model
C-Compact can be configured for a wide variety of carsharing concepts. These include the following variants:
- Station-based carsharing
- Free-floating carsharing
- One-way carsharing
With C-Compact, access to the vehicles can be controlled. At the same time, all relevant data for statistical evaluations, billing, maintenance work and more can be collected directly via the carsharing system and transmitted to the head office.

Full security in deployment and use
Convenient use by customers
C-Compact ensures that only authorized persons have access to your car-sharing vehicles. For this purpose, the reservations from your reservation system are transmitted to the vehicle in encrypted form via our CCom server – the trips can then be started by the authorized person. Our carsharing system supports various models to identify the customer and unlock the vehicle:
Plenty of memory for many trips – up to 99 bookings can be stored in the internal device memory. Trip and event data are also stored temporarily. As a result, smooth operation is always guaranteed even in the event of a connection interruption with the cell phone network or with low network reception.
Even in underground car parking areas without cellphone network coverage, access to the vehicle is possible without any problems – our carsharing system transmits the crypted booing/electronic key also to the user’s app and from there via BLE to the device in the car. The authorized driver is able to unlock the vehicle by tapping onto the push of a button in the app.
Antitheft and abuse protection
There are several security mechanisms in place if the user does not have a valid authorization to access the vehicle. In addition, our carsharing system supports a number of automated control and monitoring mechanisms that ensure operation. These include the following features:
- Convadis immobilizer
- Possibility to receive GPS positioning messages (time cycling, on request, on event)
- Alarm system for transmitting special events (low battery/unplanned vehicle movement/system-critical information)
- Integrated accelerometer records unusual events
- Monitoring of vehicle keys and fuel/charging or parking cards (C-Intac)

Our carsharing system also provides remote access. In addition to retrieving data, the vehicle can also be unlocked or locked remotely. This gives you control over your carsharing fleet even from distance. In addition, remote analyses and remote updates are possible at any time.
Data acquisition as required
In addition to safety and a high-level of operating comfort, the collection, transmission, and evaluation of trip and vehicle data are also core elements of a strong car-sharing system. C-Compact gives you the possibility to configure the details of the data collection processes according to your needs to continuously optimize your fleet management. The following is a selection of the available information:

Start time of trip |
End time of trip |
Driven distance |
Mileage at the start and end of the journey |
Information about removal and return of fuel/charging/parking cards |
Fuel level or charge level and charge plug state for full electric vehicle models |
GPS coordinates/tracking information |
Information about ignition (on/off), doors (open/closed/locked), windows (open/closed) |
Fuel or charge levels for electric and hybrid vehicles |

Diagnostic information / fault codes stored in the vehicle |
Information about removal and return of fuel/charging/parking cards |

The “Always on” technology of our carsharing system enables real time transmission of the data to the head office. This means that you, as a carsharing provider, is always informed in detail about the actual state of your vehicles.
