Virtual sensors for health and usage monitoring

Forecast component wear and tear to optimize maintenance

Are you looking for true predictive maintenance – way beyond On-Board Diagnostics (OBD)?

If you are working for a vehicle manufacturer, detailed vehicle health and usage monitoring (HUM) help to enable personalized maintenance plans and to minimize warranty costs. Virtual Sensors for health and usage monitoring enable:

  • End-of-life prediction for accurate and personalized predictive maintenance for your customers
  • Early anomaly detection to mitigate risks in the field
  • Data-driven car health certificate to increase vehicle residual value
  • Realistic usage profile statistics for usage-driven component design to reduce weight, environmental impact and product costs

If you are a fleet manager or fleet service provider, vehicle health monitoring is the foundation of predictive maintenance, as a milestone on the path to operational excellence in fleet business:

  • It reduces maintenance costs, workshop throughput time and CAPEX for spare parts
  • Usage monitoring allows educating drivers, to maintain vehicles in good condition for as long as possible
  • Early warning about weak signals of failure helps to avoid breakdowns during operation
  • Anomaly detection increases driver safety

COMPREDICT provides AI-based Virtual Sensors for health and usage monitoring of :

  • Passenger car
  • Light-commercial vehicle
  • Truck
  • Bus
  • Agricultural vehicle
  • Heavy industry vehicle
  • Two-wheeler

Our Virtual Sensors only use standardly available signals and data of vehicles to compute detailed information on vehicle usage and condition for a wide spectrum of components like tires, brakes or batteries.

Detect anomalies and forecast component wear and tear to optimize maintenance and reduce warranty costs

How do Virtual Sensors for Health and Usage Monitoring work?

The deeper you dig into vehicle data, the more actionable insights you find.

COMPREDICT’s Virtual Sensors portfolio for health and usage monitoring includes:

  • Vehicle mass
  • Tire tread depth
  • Brake pad and disc thickness
  • 12/24V battery condition
  • Independent assessment of high voltage (HV) battery state-of-health (SOH)
  • Early detection of high voltage battery anomalies stemming from raw materials, cell manufacturing or assembly
  • Tailored insights into fatigue, damage and durability of mechanical and mechatronic components like chassis, suspension, tie rod, drive shaft or transmission

In addition to current status information, forecasts allow looking into the future. For every given vehicle, they indicate the most likely future wear and end-of-life.

In case of a sudden change in how a specific vehicle is used, e.g., harsh driving style, our Virtual Sensors quickly reflect the likelihood of accelerated wear or fatigue caused by the more demanding usage.

A Virtual Sensor can mirror any targeted physical quantity or information if proper and conclusive input and reference data are available for Virtual Sensor calibration.

Our Virtual Sensors use standard available vehicle signals, e.g., CAN bus signals, like engine speed, engine torque, wheel speeds, steering angle, etc.

Benefits for vehicle manufacturers:

  • Enabler for personalized predictive maintenance for increased customer retention
  • Key indicators to manage warranty costs
  • Ground truth for car health certificate
  • Realistic, representative usage profiles that keep you up to date with changing customer behaviour
  • Reliable, detailed field data that enable usage-driven component specifications, resulting in lower product costs, reduced CO2 impact and optimized durability

Benefits for fleet managers:

  • Enabler of true predictive maintenance
  • Reduction of error-prone, time-consuming manual maintenance checks
  • Easier workshop operations and reduction of throughput time
  • CAPEX optimization on spares stock
  • Reduction of unplanned downtime with early detection of failures

Deployment:

  • Cloud-to-cloud integration (OEM infrastructure or fleet solution)
  • Embedded in vehicles on your existing electronics (ECU or telematics hardware)
  • Fast deployment via the data insights platform BlackBerry IVY

How precise are our Virtual Sensors for Health and Usage Monitoring?

The granularity and precision of the Virtual Sensors we deliver rank from a basic traffic light status (green/orange/red) to very accurate wear indicators (sub-mm in the case of tire wear). It depends primarily on the quality of your input data and on the reliability of the reference values used for calibration. We are happy to support you here.

The quickest way to estimate realistic output quality for your use case, is to provide us with a set of sample data.
