ISO 16844-1 is the first part of the ISO 16844 multi-series regarding tachograph systems in road vehicles.
ISO 16844-1 specifies the mechanical dimensions of mandatory connectors and optional connectors used by the recording equipment for the data and the service interfaces. This includes, in particular, the connection to the CAN-based in-vehicle networks.
ISO 16844-1 on tachograph systems in road vehicles is useful for:
The digital tachograph concept is based on recording equipment storing data, related to the activities of the various drivers driving the vehicle, on which it is installed. A tachograph system consists of various components which need to be well integrated within the vehicle to function as intended.
ISO 16844-1 provides you with connector dimensions for tachograph systems and guides you to connect the various components in their intended connections. ISO 16844-1 also provides you references to test method documents that will help you verify the tachometer systems’ performance.
Overall, the guidelines of ISO 16844-1 ensure that the electromechanical components of tachometers are well integrated into your vehicle and are functional.
BS ISO 16844-1:2022 supersedes ISO 16844‑1:2013, which has been technically revised.
The main changes are as follows:
