Fraud and anomaly detection in your vehicle fleet

A vehicle with no activity for 60 days, general maintenance invoiced twice in 90 days, a contractual mileage exceeded: Dadycar's business rules spot them before the accounts close.

What anomaly detection changes

  • 19 anomaly types in three families: data integrity, potential fraud, contractual compliance.
  • Three priority levels (high, medium, low), with a handling deadline and a notification channel.
  • With no device: the rules apply to the management data already held in Dadycar.

What escapes a manual check

  • A duplicated servicing expense disappears into the month's pile of supplier invoices.
  • A vehicle that no longer runs keeps costing lease, insurance and fuel card.
  • A contractual mileage overrun is discovered at return, together with the lessor's penalty.

What you get with Dadycar

The Anomalies module is a business rules engine applied to fleet data: vehicles, contracts, expenses, servicing, fuel cards, odometer readings. It is separate from the telematics alerts coming from sensors.

Potential fraud

Expenses repeated over a short period, such as general maintenance recorded twice in 90 days, or activity inconsistent with the vehicle's data.

Data integrity

A vehicle with no activity at all for 60 days, an inconsistent odometer reading, an incomplete record: wrong data is flagged before it distorts the reports.

Contractual compliance

Contractual mileage exceeded or about to be, according to the mileage terms, contract deadline approaching, gap between usage and contract.

Priority and deadline

Each anomaly type has a high, medium or low level; each instance has a handling deadline and a status.

Notification to the right channel

The notification channel is set per anomaly type; the owner receives what concerns them, the dashboard shows the rest.

Instances tracked

Every trigger creates an instance attached to the vehicle, with its history, to document internal control and exchanges with suppliers.

How it works

  1. 1Feed Dadycar with your management data. Vehicles, contracts, expenses, fuel cards and odometer readings: the rules apply to what is already entered or imported.
  2. 2Choose which anomaly types to switch on. Priority, deadline and notification channel for each type.
  3. 3Handle the instances. The dashboard shows open, overdue and resolved anomalies; sensor signals stay in the telematics alerts.

Who it is for

  • Finance and management control: duplicated expenses and dormant vehicles spotted before the accounts close (see the role page).
  • Fleet managers: contractual mileage monitored with no spreadsheet (see the role page).
  • Transport and logistics: fuel cards and servicing checked across fleets of several hundred vehicles (see the industry page).

Your first anomalies, visible during the trial

Import your fleet and your expenses: the standard rules run on your data and show you what the spreadsheet was missing.

Your questions before getting started

  • “Do I need a device?” No. Anomalies relate to management data; telematics enriches some rules with real mileage.
  • “An anomaly is not proof of fraud.” Correct: the module flags a situation to check, with its priority; the decision stays with the manager.
  • “How long does it take to start?” The anomaly types are predefined; they run as soon as the matching data is in Dadycar.

Frequently asked questions

What is an anomaly in fleet management?

It is a situation detected by a rule applied to the fleet's management data that departs from what is expected: a vehicle with no activity, a duplicated expense, a contractual mileage exceeded, an incomplete record. It differs from a telematics alert, which comes from a vehicle sensor.

How do you detect fuel card fraud in a fleet?

By cross-checking card data (issuer, limit, invoices) with the vehicle and its usage: expenses repeated over a short period, activity inconsistent with odometer readings, an inactive vehicle still consuming. Dadycar files these situations under “potential fraud”, with a priority and a deadline.

What is the difference between an anomaly and a telematics alert?

A telematics alert comes from a vehicle signal (engine warning light, tyre pressure, impact) and requires a device or a connected vehicle. An anomaly comes from a business rule on management data and works with no hardware. Dadycar handles them in two separate modules.

What is contractual compliance for a leased vehicle?

It is compliance with the terms of the lease: contractual mileage, duration, mileage terms (the expected mileage progression), condition at return. Dadycar compares actual mileage with the contract, flags the overrun or its approach, and tracks the deadline.

How are anomalies prioritised and notified?

Each anomaly type has a priority level (high, medium, low) and a notification channel. Each instance carries a handling deadline and a status; the dashboard shows open, overdue and resolved anomalies.
