IAA 2018

Bringing CAN data into the clouds

One of the major trends at IAA 2018 was telematics. It seemed that everyone likes to offer fleet management services or to provide related gateways.

The 67th IAA commercial vehicles tradeshow took place in Hanover (Germany). From September 20th to 27th, about 2100 exhibitors presented their products and services. One of the main topics was cloud services and big data processing. Nearly all OEMs (original equipment manufacturer) exhibited devices and services for telematics. They bring the data available on the CAN-based in-vehicle networks into the cloud. Volvo launched it Connect online portal for its customers. It seems to be profitable to offer such fleet management services. Also market-leading trailer manufacturers such as Schmitz Cargobull and Krone have developed their own solutions and offer such web services to fleet owners. Schmitz Cargobull cooperates with Idem providing the Cargofleet3 telematics system. Idem is a BPW subsidiary. Schmitz Cargobull provides its own Trailerconnect portal.

If the truck or trailer body builder would do the same, each vehicle set will be equipped with multiple antennas and gateways to the in-vehicle networks, where the data is generated. At the end, the vehicle owner has to deal with several cloud services, which are not yet interoperable.

DIN 4630, a German standard under development, is going to specify a CAN-based network connecting manufacturer-independent body applications to the cloud. A typical example is a refrigerating truck with tail-lift. Both body applications are coming from two different suppliers. Bär Cargolift presented a prototype implementation of such a network connected to a telematics gateway by Idem. The protocol was based on J1939, another option of DIN 4630 is CANopen. Iveco offers in all of its trucks CANopen-based interfaces for body builders compliant to CiA 413 series. The other European OEMs provide J1939-based proprietary gateways to the in-vehicle networks.

Also Tier1 supplier such as Bosch, Continental, and Wabco offer fleet management services. Wabco’s Traxee fleet management system addresses especially small and medium-sized companies. Continental presented its Conticonnect Live available from the second quarter of 2019.

The base: Gateways with CAN connectivity

Gateway hardware with CAN connectivity and multiple interfaces for telematics was presented on many stands. Some of them derived from the passenger car industry. Typical automotive examples was shown on Preh’s stand. But also dedicated commercial vehicle telematics products were presented at IAA 2018. Actia, a French company, showed a complete series of such products all connectable to the CAN-based in-vehicle networks.

Of course, the data transmitted into the cloud needs to secured. From the telematics gateway to the cloud there are available proprietary security mitigation solutions. But the CAN-based in-vehicle networks are not secured. This means, faked data can be transmitted securely into the cloud and data received securely from the IT service provide can be manipulated after the CAN interface of the telematics unit.
