What Is Sensor Fusion

Sensor fusion is the method LETSTOP uses to combine multiple sensor types into one reliable picture of your drive. No single sensor is perfect on its own, but together they create a stronger signal that improves detection accuracy.

The Three Layers of Sensor Data

LETSTOP analyzes three main categories of signals to understand your movement.

When fused together, these signals tell a consistent story about what is happening.

Why GPS Alone Is Not Enough

GPS can show general movement, but it has limitations, especially in tunnels, parking garages, or areas with poor signal.

Motion sensors fill these gaps by showing that the vehicle is still moving even when GPS is uncertain.

How Motion Sensors Improve Accuracy

Accelerometer and gyroscope data provide rapid updates that help detect the beginning and end of a trip with better precision.

This makes trip detection more reliable across different situations.

Fusing Sensors for Better Trip Recognition

The app combines sensor data to create confidence scores. When GPS and motion both suggest movement, the system becomes highly confident you are driving. When they conflict, AI models help interpret the situation.

Reducing False Motion Detections

Sensor fusion helps LETSTOP avoid misclassifying non driving movement such as being on a bus, train, or bike.

By recognizing these unique signatures, the system maintains accurate trip detection.

A Stronger System Over Time

As more anonymized trips are analyzed, the fusion models grow better at recognizing edge cases. This means improved precision for all users without collecting any sensitive information.
