Tachograph analysis software has an unglamorous job: take a file off a card or a vehicle unit, work out what the driver did, compare it with the limits, and list what crossed them. The arithmetic is not the hard part and no vendor's is meaningfully better than another's. What separates products, and what an office should be judging them on, is everything around the arithmetic: what happens to a finding once it exists, whether the evidence stays yours, and how much of the month it takes to run.
What it does to a download
It reads the file, splits the activity into driving, other work, availability and rest, totals each against a day and a week, and marks where a limit was crossed. Everything a product shows you afterwards, the graphs, the league tables, the traffic lights, is a presentation of that. If two products disagree about a driver's day, one of them has read the file differently, and that is worth understanding before it becomes an argument with a driver.
The part that is not the maths
A finding has to be put to the driver, explained, signed and kept. That loop is the compliance regime and it is where products differ most: some stop at a report, some manage the conversation, some do nothing until you export to a spreadsheet. An office buying on detection accuracy is buying the part every product already does well.
Where the reader ends and the software begins
A card reader and a download utility produce a file. Digital tachograph software analyses it. They are often sold together and are separable, which matters when a bureau reads your cards or when the download is remote: the file has to land somewhere that can hold it, and the office should know which product owns which half.
When tachograph analysis services are the better buy
A bureau suits an operator with no office time and few enough drivers that a monthly report is enough. It stops suiting one that wants to see a finding the week it happened, or that is preparing for a public inquiry and needs the evidence in its own hands. Both are legitimate; the mistake is paying for both and using neither properly.
Questions people ask about tachograph analysis software
What does tachograph analysis software do?
Reads a card or vehicle unit file, splits and totals the driver's activity, compares it with the limits the operation works to, and lists the infringements. What happens to those findings afterwards is what separates products.
Is analysis software the same as a downloader?
No. The downloader produces the file, the analysis reads it. They are often bundled and are separable, particularly where downloads are remote.
Do we need it if a bureau analyses our cards?
Not necessarily. The question is whether you need the record in your own hands and sooner than a monthly report, which is usually what changes when an operator's licence is under scrutiny.
What does Tachovo do here?
It keeps the record: the download and its date, the analysed driving against the limits you set, and the infringement raised, sent and signed. The free drivers' hours check on this site does the forward-looking half.
