The Fuel Desk Agent is an AI system that recommends the lowest-cost fuel stops for your trucks based on real-time fuel prices, truck location, and route efficiency. It works in the background to find savings opportunities on every load.

How it works

When a driver picks up a new load, the Fuel Desk Agent analyzes:

• Current fuel level - from your telematics system
• Route waypoints - where the truck is going
• Nearby fuel stations - using HERE Maps
• Contracted fuel prices - updated daily from your fuel network
• Truck efficiency - historical MPG data to predict range

The agent calculates a fuel score for each station, weighing price against detour distance. Stations close to the route and cheaper rank highest.

Score calculation

Scoring depends on fuel level.

High fuel (70% or more)

• Less urgency, wider search
• Score = price * (0.75 + 0.25 * detour_penalty)

Medium fuel (between 20% and 70%)

• Balanced approach
• Same formula as High

Low fuel (less than 20%)

• Act fast, prefer distance
• Score = 0.85 * distance + 0.15 * price

The detour penalty is calculated as min(miles_off_route / 3.0, 1.0), capped at 3 miles perpendicular to route.

Lower scores are better. The agent recommends the station(s) with the lowest score.

Driver notifications

Recommendations arrive as messages through your integration channel (Telegram is an example). They include:

• Station name and brand
• Distance from truck and from route
• Current fuel price and your contracted rate
• Estimated savings for a full tank
• Arrival time window at the stop

The driver can accept, defer, or ignore the recommendation. Deferred recommendations resurface as fuel level drops.

What happens if a driver misses a stop

If a recommendation is ignored and fuel drops below the next 200 miles (or to 15% tank), the agent flags it as a missed stop and logs the savings that were left on the table. This helps identify driver patterns and coach on fuel discipline.

Customization

Contact your Drafft admin to adjust:

• Allowed fuel networks - whitelist branded stations (Pilot, Love's, Circle K, etc.)
• Emergency threshold - tank % that triggers an urgent "fuel now" message
• Corridor width - how far off-route counts as acceptable (default: 3 miles)

Integration channels

Fuel Desk recommendations are sent via your configured integration. Telegram is one example; others may be available depending on your Drafft plan.
