What are the benefits of GPS/IMU data in CAN diagnostics?

Integrating GPS and IMU data with CAN diagnostics delivers numerous practical advantages that significantly enhance vehicle testing and analysis capabilities. The primary benefit is the ability to contextualise vehicle data with precise location information, creating a spatial dimension to diagnostics that reveals patterns and correlations otherwise invisible.

Route mapping becomes extraordinarily powerful when combined with CAN data, allowing engineers to identify how specific road conditions, gradients, or environments affect vehicle systems. For instance, fuel consumption patterns can be mapped to terrain features, or emissions behaviour can be correlated with urban versus highway driving segments.

Acceleration testing gains precision through GPS/IMU integration, enabling exact measurement of performance metrics like 0-60 mph times with synchronised engine, transmission, and traction control data. This reveals how vehicle systems interact during dynamic manoeuvres, highlighting opportunities for optimisation.

Vibration analysis benefits substantially from IMU data, particularly when investigating ride comfort, suspension performance, or noise issues. By correlating IMU-detected vibrations with CAN signals from relevant systems, engineers can pinpoint the root causes of unwanted vibrations or acoustic phenomena.

Perhaps most valuable is the ability to correlate vehicle systems performance with specific driving scenarios. For example, battery management system behaviour in electric vehicles can be analysed across various driving conditions, revealing how terrain, driving style, and climate impact efficiency and range.
