The problem this solves

Fleet maintenance sits between two bad options. Fixed-interval servicing replaces parts that had plenty of life left and misses the ones that failed early, because a schedule written for an average vehicle fits very few actual vehicles. Running to failure is cheaper on paper until the first roadside incident, which brings recovery, a driver stranded, a load that did not arrive and a workshop slot taken at short notice.

Most modern commercial vehicles emit enough data to do better. Fault codes, exhaust and coolant temperatures, battery voltage behaviour, brake wear, fuel consumption drift, and the duty cycle the vehicle actually experiences rather than the one the schedule assumed. A tipper on short urban runs ages nothing like a tractor unit on motorway line-haul, and the maintenance interval rarely reflects it.

Where this goes wrong is in overselling. Some components fail with observable degradation over weeks — batteries, brake pads, injectors, turbochargers — and those are genuinely predictable. Others fail abruptly with little warning in the telematics data, and a model asserting a 30-day horizon on those is producing noise. A useful product is explicit about which components it covers and which it does not.

Where the data comes from

Vehicle telematicsCAN bus and telematics streams from your own units or your telematics provider — the primary signal and the main integration work
Fault code historyDiagnostic trouble codes with timestamps, which become useful when paired with what the workshop subsequently did
Workshop and repair recordsCompleted jobs, parts replaced and failure descriptions — the labels, and usually the messiest data in the project
Vehicle specification dataMake, model, drivetrain and fitted components, so a model is not trained across incomparable vehicles
Manufacturer service schedulesPublished intervals as a baseline the predictions adjust rather than replace
Operational recordsRoutes, loads and gradients, which define the duty cycle the vehicle actually experiences
On data licensing. Being allowed to read a dataset does not automatically mean you may redistribute it, resell it through an API, or train a model on it. Before any build starts we check the licence, terms and derived-data rules of every source, and we design around the ones that do not permit your intended use. Where a commercial licence is required, that cost is identified during discovery rather than discovered later.

The intelligence layer

The difference between a demo and a service is mostly in this section. These are the parts that keep the answer trustworthy once real traffic is hitting it.

  • Component-level models rather than one vehicle health score, because a battery and a brake pad share no degradation physics
  • Explicit coverage boundaries: components without a usable degradation signal are reported as not modelled instead of given a fabricated risk
  • Duty cycle classification from telematics, used to adjust intervals — the same odometer reading means different wear on urban stop-start than on line-haul
  • Remaining useful life as a distribution, with the lower quantile being the number a planner actually schedules against
  • Fault code interpretation grounded in your fleet's own historical outcomes rather than the generic code description
  • Survival models with censoring handled properly, since most components in the training data have not yet failed
  • Workshop scheduling as a constrained grouping problem: batching work on a vehicle, respecting availability and bay capacity
  • Continuous recalibration against reported outcomes, with per-component accuracy published and components dropped when they do not validate

What it changes for the business

Planned instead of roadside

Work moves into booked workshop slots, which costs a fraction of a recovery and a missed load.

Intervals that fit the vehicle

Duty-cycle-adjusted servicing stops replacing good parts on easy-duty vehicles and catches hard-duty ones earlier.

Grouped workshop visits

Batching predicted work into one visit reduces total downtime more than any single prediction does.

Honest coverage

Naming the components that are not predictable keeps trust in the ones that are.

How we would build it

about 20 weeks
1

Discovery and feasibility

Weeks 1–3

This one depends heavily on data access, so we start by proving the sources exist, can be licensed for your use, and actually carry the signal the model needs. If they do not, you find out here.

2

Architecture and baseline model

Weeks 4–6

A written architecture and a baseline model measured against a holdout period, so you know what accuracy you are buying before the full build starts.

3

Production build

Weeks 7–16

Data pipelines, model training and serving, historical archive, validation harness, API, security, monitoring and documentation.

4

Validation and integration

Weeks 17–20

Backtesting against held-out history, accuracy reporting your team can audit, integration support and an agreed retraining cadence.

Commercial models

There is no fixed price list, because the cost is driven by data complexity, integration count, model requirements, request volume and the support level you need. Scope is agreed in writing before development starts.

Fixed-scope prototype

A defined slice of the service, built and priced as one piece of work. The usual first step when the business case needs proving internally.

Fixed-price build

An agreed scope against a written architecture, delivered for an agreed price. Best when the requirements are already clear.

Build then retainer

We build the service, then operate and improve it under a monthly agreement covering monitoring, updates and model maintenance.

White-label product

The service runs under your brand, your domain and your pricing, with MLPivot invisible to your customers.

Questions buyers ask

Which components can you actually predict?

Those with an observable degradation signal in the available data: starter batteries, brake wear, EGR and aftertreatment issues, some injector and turbo conditions, tyre wear where sensors exist. Clutches, gearbox internals and many abrupt mechanical failures are not reliably predictable from telematics, and the API reports them as not modelled. A product that returns a risk figure for every component is giving you noise with a decimal point.

How much history do you need?

At least a year of telematics paired with workshop records, and enough failure events per component to learn from — in practice a few dozen. A fleet of thirty vehicles will not have that for most components, and the sensible approach there is pooling across similar fleets if the data is available, or starting with the components where the signal is strong enough to work on physics rather than history.

Our workshop records are a mess. Is that fatal?

It is the usual situation and it is the main cost in the project. Free-text job descriptions, inconsistent part naming and repairs recorded days after the fact all have to be reconciled before anything can be trained. We scope that work explicitly in discovery rather than discovering it in week six, and sometimes the honest finding is that the labels will not support a model for a particular component.

Will it reduce our maintenance spend?

It should shift spend rather than only reduce it — fewer roadside incidents and fewer premature replacements, but also some components replaced that a fixed schedule would have run longer. The clearer saving is in downtime and recovery, which is usually the larger number. We would measure it against your own historical baseline rather than quote a figure.

Does this replace statutory inspections?

No. Legally mandated inspections and maintenance remain exactly as they are, and the predictions sit alongside them. Nothing in the API should be read as permission to extend a regulated interval.
