Enable new measurement capabilities for series and development vehicles at low costs
The next phase of automotive evolution is the Software-Defined Vehicle (SDV), receiving new capabilities from Virtual Sensors:
The Software-Defined Vehicle offers:
- Continuous improvement and enhancement with new functionalities
- Updates Over-the-air (OTA)
- New Functionality without adding any new hardware
The critical raw material for such evolutive software product features is available from in-vehicle data.
With COMPREDICT’s Virtual Sensors, you can extract hidden information from existing vehicle data.
Enable additional measurement capabilities for all kinds of vehicles
How does an additional measurement by a Virtual Sensor work?
A Virtual Sensor can mirror any targeted physical quantity or information if conclusive input data and reference data are available for calibration. Our Virtual Sensors enable use cases like:
- Wheel forces and torques
- Tire and brake wear
- Vehicle mass
- Suspension displacement
- Steering forces
- And many more
Our Virtual Sensors only use vehicle signals as inputs which are standardly available in any series-production vehicles, like engine speed and torque, wheel speeds, steering angle, etc.
We generate Virtual Sensor through the following steps:
- Data selection by our vehicle experts or through automated Virtual Sensor calibration pipelines
- Data clean-up and preparation for Virtual Sensor calibration
- Actual Virtual Sensor calibration to match the target values given by reference data
- Calibration validation on a separate set of validation data
- Deployment in a cloud architecture or embedded in vehicles
The reference data can be derived from lab tests or vehicle test campaigns with real hardware sensor data, like a wheel force transducer, or manual measurements, like brake pad thickness.

Virtual Sensors deployment
- For cloud implementation, we work with major cloud providers like AWS and Azure.
- At the edge, Virtual Sensors can be deployed on electronics hardware like an electronic control unit (ECU) directly in the vehicle
- Edge deployment is significantly accelerated and facilitated by BlackBerry IVY as a middleware layer, as it reduces the complexity of embedded software development and configuration management
Your benefits of using Virtual Sensors
- New measurement capabilities with existing hardware configuration
- Lower total costs of ownership (TCO) compared to adding hardware sensors into each vehicle
- Enabler for new digital services in series-production vehicles
- Shorter R&D lead times, through extended test campaigns at larger scale by turning series-production vehicles into R&D vehicles
