Telematics: OBD or CAN?

When it comes to telematics data, these days the question is no longer whether you need it, but rather which system you should choose. Depending on the size and requirements of the operation, fleet managers can choose between a cheaper on-board diagnostics port (OBD) and a more sophisticated and expensive controller area network system (CAN). The decision as to which is most suitable requires careful consideration on a case-by-case basis. 

OBDs

The option of an OBD solution results in a reduced cost for installation and an easy-to-understand way of gathering and accessing telematics data. However, spending less inevitably means that you’ll have to compromise on features that affect performance and security.

While some people make the mistake of believing that it's simply a matter of installing the software and instantly gaining access, in reality that's not the case. The majority of devices need professional installation, not only because of the positioning of the socket in the vehicle, but also in order to maximise their GPS capabilities.

The accessibility of OBD systems also leaves them open to tampering and the possibility of being disconnected accidentally (during servicing) or intentionally. The nature of the software can also create some security issues, as it could be hacked through its connection via 2, 3 or 4G networks. In certain circumstances, it can also set off a vehicle's alarm or warning systems at random. 

There are currently some complex issues surrounding the use of OBDs and vehicle manufacturer warranties, which need to be investigated thoroughly before deciding to install a device.

CANs

Installing the costlier CAN software system means that data comes directly from the software itself (which is located behind the dashboard of the vehicle), offering premium performance and enhanced security of telematics data. The software enables a more intuitive dashboard solution that doesn’t require intrusive access through cabling or physical connections.

CAN software generates large volumes of accurate, real-time information, which instantly translates the raw telematics data into a vital and highly usable insight into core areas of business operations across the board, including maintenance, health and safety, fleet management and utilisation of equipment. These cloud-based systems enable a highly efficient way of reducing costs and increasing productivity across a mobile workforce.

Maximising Telematics Data

Monitoring driver and vehicle behaviour offers multiple benefits, such as allowing for the provision of targeted driver training where it's needed and generating improvements in productivity and profits through increased fuel economy and reduced vehicle wear and tear. Many of the software solutions are developer-friendly, allowing for simple third-party integration. This ease of integration means that using them in conjunction with platforms like Courier Exchange (the UK's most trusted freight exchange network) enables real-time access, enhanced functionality and instant application across operations.

The choice of whether to install an on-board diagnostics system or a controller area network system of telematics software will depend on budget, fleet size and the expectations and use of the data gathered. The bottom line is that – as always – a reduced cost brings about compromises.
