CAN FD bus handling by S10.3/S10.5 Terminals

Similar to how telecommunications operators are phasing out 2G networks, vehicle manufacturers are also abandoning CAN in favor of CAN FD. By discontinuing 2G networks (in most European Union countries by the year 2025), operators are essentially pushing for the replacement of telemetry devices operating on 2G technology with devices that operate on LTE technology. When replacing devices for this reason, it is advisable to take a decidedly pragmatic approach and not exchange outdated 2G devices for LTE devices without CAN FD support. Instead, opt for devices that have CAN FD capability.

Unfortunately, an improper decision in the near future will once again necessitate the replacement of telemetry devices. This time, the replacement will be for a device equipped with CAN FD. It is therefore worthwhile to approach this situation rationally now, to avoid incurring double costs for device purchases in the near future. Why go through the process of replacing newly installed devices shortly afterward to adapt to the currently widely implemented new type of bus? Wouldnt it be better to do it all at once right now?

In the near future, manufacturers of all vehicles are planning to implement a new CAN standard called CAN FD. CAN FD enables faster and larger data exchange between various electronic components in a vehicle. With the implementation of CAN FD, vehicles are capable of handling a growing number of sensors, actuators, and other electronic elements, leading to improvements in both the efficiency of system operations and the safety and comfort of driving. This standard plays a crucial role in the evolution of modern vehicles.

Our S10.3/S10.5 terminals already feature a state-of-the-art processor that enables CAN FD bus support. According to our market research, we stand out among GPS terminal manufacturers by offering devices equipped with CAN FD technology.

In practice, what does the lack of CAN FD support by the competition mean?

The lack of CAN FD bus support means the inability to read logistic data from the CAN bus of vehicles (!) that will be equipped exclusively with this type of bus. Therefore, it is extremely important for devices installed in vehicles to have CAN FD support, considering the fact that they will be in use for many years to come. Competitive devices without CAN FD support do not have the capability to read data from the buses of vehicles equipped with this type of bus. Such a device becomes useless as there is no remote possibility of adapting it to the new standard. A physical change of the device is required, which involves incurring significant costs again.

Certification

The processor in S10.3/S10.5, capable of reading data from the CAN FD bus, is specifically designed for automotive solutions. Consequently, it holds relevant certifications, including:

AEC-Q100 qualified means that the processor has undergone tests in accordance with this standard, indicating that it is durable, reliable, and meets rigorous environmental requirements associated with extreme conditions that may occur in automotive applications. These conditions include large temperature fluctuations, vibrations, and variable voltage.

ASIL-B, ISO 26262 means that the processor meets specific requirements regarding design, testing, and documentation to ensure safety in the event of potential failures or errors in the electrical or electronic system of the vehicle.

ISO CAN FD support means that the processor complies with ISO standards defining protocols and requirements for CAN FD communication.

The possession of the mentioned certifications is crucial because in the future, vehicle manufacturers may require that the installation of additional accessories in a car is only possible if the processor communicating with the vehicle bus has undergone specific tests, based on which the mentioned certifications have been awarded.
