VIRTUAL SENSORS FOR ADDITIONAL MEASUREMENT CAPABILITIES

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:

  1. Data selection by our vehicle experts or through automated Virtual Sensor calibration pipelines
  2. Data clean-up and preparation for Virtual Sensor calibration
  3. Actual Virtual Sensor calibration to match the target values given by reference data
  4. Calibration validation on a separate set of validation data
  5. 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.

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 Virtual Sensors for additional measurement capabilities

  • 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

To guarantee the quality of our Virtual Sensor results, we collaborate with a leading reinsurance company, MunichRE.
