Sentinel

In a mine, at a well site, inside a plant — the speed limit is not a suggestion. And every single day, somebody goes past it.

The gap telematics leaves

Signs stop no one and training fades. Telematics, which is what covers that gap today, reports it after the fact: the speeding report lands on Monday and the incident happened on Thursday. That is a record, not a control — it describes an operation that already happened instead of changing it.

Sentinel acts earlier. Rather than counting the violation, it makes it impossible.

Between the pedal and the ECU

Sentinel installs between the accelerator pedal and the ECU of the vehicle. It replaces nothing and removes nothing: the pedal signal passes through the module, which reinterprets it before the engine controller ever sees it.

The driver floors it just the same. The truck delivers all its power up to that zone’s limit and no further: the curve without Sentinel overshoots the limit, and Sentinel’s climbs just as hard and flattens right on it.

Geofences per zone

The geofence is drawn from the control room, and each zone gets a limit of its own — the haul ramp, the manoeuvring yard, the plant entrance. Sentinel enforces it on its own, across the whole fleet and without touching the vehicle, so compliance stops depending on a driver remembering the number. Every operation, with a map of its own.

The emergency override

And in a real emergency? A limit that cannot be lifted stops being a safety measure at the exact moment speed is what safety calls for.

So the cab carries a covered button. The cover lifts, the button is pressed, and the limit releases instantly — temporary, or until further notice.

And the control room knows the moment it happens: the alert arrives live, with the unit, the zone and the time. The override is not a back door, it is a logged action.

Also for passenger fleets

The same module goes into city buses, where the argument is the passenger and the fuel bill: a progressive pull-away with no jolts, and 20 km/h geofences over school zones.
