Investigate incidents

Understand what really happened

Stratio continuously records deep vehicle signals, sensor data, and component behaviour, giving engineering teams the evidence they need to investigate incidents, understand failures, support warranty claims, and answer questions about the vehicle long after they happen.

Vehicle incidents are difficult to reconstruct

A collision or unexpected failure can raise questions long after it happens.
The vehicle evidence needed to answer them is rarely available.
Teams are left piecing together incomplete records and notes.

Missing evidence makes incidents harder to investigate, failures harder to explain and warranty claims harder to prove.

Record the vehicle, not the event.

Stratio continuously records vehicle condition, sensor data, and deep CAN signals throughout the life of the bus. When questions arise later, engineering teams can go back through the vehicle’s history to understand exactly what happened before, during, and after the event.

Every journey becomes part of the
vehicle’s history

Stratio continuously records vehicle behaviour, so teams can review how a vehicle performed over time.

For every vehicle, teams can investigate:
Speed and location
Deep CAN signals and sensor behaviour
Battery and component health
Vehicle condition around an incident

This gives the workshop evidence that the repair held, or an earlier warning that the issue remains.

Answer questions with evidence, not assumption

Investigate incidents with complete vehicle history
Understand vehicle behaviour before and during an event
Support warranty and supplier discussions with evidence
Analyze battery degradation across the fleet
Give engineering, operations, insurers and authorities the same evidence

Six battery packs: evidence before the warranty window closed.

At one operating entity, Stratio identified six high-voltage battery packs degrading against the fleet baseline while they were still under warranty.

The same reliability record that detects the issue also gives warranty, engineering, and operations teams the evidence trail they need after the fact.

We adopted Stratio in 2020 to test whether failure prediction was real. The results speak for themselves: cost per km decreased, time between failures went up, and what began as a pilot in the Prague region is now a standard we keep expanding.

Stratio’s technology is enabling us to operate more efficiently, both in the workshop and in day-to-day operations by preventing bus failures and scheduling preventive maintenance at exactly the right time. This helps reduce costs while increasing vehicle availability. All of this translates into higher service quality, minimizing route disruptions and providing a safer and more comfortable driving experience.

// Frequently asked questions

Have any questions? We’ll get back to you in 24 hours.

What kinds of questions can Stratio help answer?

Stratio helps teams understand what happened before, during, and after an event. That includes collisions, unexpected failures, battery degradation, warranty claims, recurring faults, and operational incidents where understanding the vehicle’s behaviour is critical.

What vehicle data does Stratio record?

Stratio continuously records deep CAN signals, sensor data, battery behaviour, component performance, fault activity, operating conditions, and other vehicle telemetry. This creates a detailed vehicle history that engineering teams can review whenever questions arise.

Does Stratio determine the cause of an incident?

Stratio provides the vehicle evidence. Engineering teams, operators, manufacturers, insurers, or public transport authorities use that evidence to investigate what happened and make informed decisions.

Can Stratio support warranty and battery investigations?

Yes. By continuously recording battery performance and vehicle behaviour over time, Stratio helps teams identify long-term degradation, compare vehicles across the fleet, and provide evidence when warranty claims arise.

Can the same vehicle history be used by different teams?

Yes. Engineering, maintenance, operations, insurers, manufacturers, and public transport authorities can all work from the same vehicle history, reducing the need to reconstruct events from multiple disconnected sources.
