Use cases

The Sonatus suite of products deliver capabilities that accelerate innovation, improve vehicle quality, enhance customer experience and add new sources of revenue. They power use cases spanning vehicle design and engineering, production, after-sales service and value-added vehicle services.

Design and Engineering

Improve range with real-world data

Increase EV range use caseAs software increasingly drives vehicle features, automotive engineers can use real-world data to improve vehicle performance.  

Challenge: Improving EV range 

For example, in order to get more efficient battery usage for better range, engineers currently rely on data from just a few test vehicles to tune motor control ECUs.  

Any calibrations made using this limited data set is often confined to new vehicles, since applying them to post-production vehicles can be inconvenient and expensive. 

An agile and automated cloud-edge solution makes it possible

Using Sonatus Collector and Automator, OEM engineers can gather real-world data to refine motor control ECU parameters for optimized battery range, and apply them directly to in-market vehicles.

  • Collector policy gathers motor performance and battery data
  • Collection is activated under various driving conditions 
  • Analysis identifies vehicle models with sub-optimal battery performance
  • Motor control ECU data map is recalibrated for better performance
  • Automator applies updates to identified models when vehicle is not in use

Offer a driving experience that gets better over time

Sonatus Collector and Sonatus Automator allows OEMs to use real-world driving data to give customers vehicles and driving experiences that continuously improve over time.  

  • Gather and analyze real-world data
  • Apply enhancements at any time in vehicle lifecycle
  • Delight customers with a continuously improving vehicle

End-of-line testing

Line testing panel use caseVehicle functional testing is vital but inefficient

Customers expect their new vehicles to just work and end-of-line tests are crucial to make that happen.  Yet it’s often a laborious and expensive part of the production process to check if the dozens of functions work as designed.  

Challenge: Check if the A/C works as designed on all new vehicles 

Rigorous testing of each vehicle function, like the HVAC system, is typically limited to technicians manually testing it on a small sample of vehicles. That can lead to some vehicles being shipped with defective systems.  

Automate A/C functional tests across thousands of vehicles

Sonatus Automator allows test engineers to automate many of the manual functional tests during end-of-line testing onsite, remotely, or as they sit idle while being readied for shipment. 

  • Engineers use Automator’s console or APIs to design HVAC test routines.
  • Routines automate complex workflows with specific triggers and actions.
  • Triggers encompass numerous vehicle signals, external APIs, or contextual events.
  • Actions include vehicle functions, diagnostics, interactions with external entities, etc.
  • Test routines are deployed remotely to production vehicles, running during idle periods.
  • Tests monitor HVAC functionality, checking if a set temperature is reached in time.
  • Large-scale tests ensure quality control in newly produced vehicles.

Improve quality testing efficiency with Sonatus Automator

This is one of many such tests that Sonatus Automator can automate to greatly reduce the operational overhead of end-of-line functional testing. Its support for a vast array of triggers and actions, automakers can dramatically improve testing efficiency and reduce the overall cost of production.

Deliver new user experience use caseSoftware-defined vehicles promise to deliver personalized driving experiences

Software-defined vehicles are expected to deliver continuously fresh and personalized user experiences. To achieve this, automakers will need software solutions that support rapid and iterative enhancements, even to those already shipped and sold. 

A new “Summer Vent” feature

An automaker wants to add a “Summer Vent” feature that automatically rolls down the windows and turns on the A/C until a comfortable temperature is reached when it’s too hot outside.   

Deliver new features without software development

Using Sonatus Automator, an OEM can simply create a recipe on the web-based UI or through APIs to automate the following Summer Vent feature workflow:

  • Workflow trigger conditions
    • Outside temperature above 90℉ (32℃)
    • Ignition status ON
  • Actions 
    • Roll down all the windows
    • Set A/C to max for 3 minutes
    • Check if cabin is cooled sufficiently
    • Adjust temperature to a comfortable setting
    • Roll up windows 

Make it user personalized 

Optionally, the OEM may choose to let users configure the amount of time to run A/C at max and their preferred temperature through the infotainment system or the companion app. 

The recipe can be deployed to a handful of test vehicles for verification before being rolled out to ones that have been shipped or sold.  The new feature is thus instantly available to all customers.  

Delight users with new and personalized driving experiences

The move towards software-defined vehicles opens up the possibilities to tailor the driving experience to individual users.  Sonatus Automator makes that possibility a reality.  

  • Endless possibilities of new features through automation 
  • Instantly create, test and deploy at any stage of vehicle lifecycle
  • Monitor feature usage to understand user preferences
  • Apply tight controls to feature creation and end user access
  • No new software development or firmware changes needed

Avoid recalls with smart diagnostics

Smart diagnostics use caseTroubleshooting failures on vehicles can be time consuming and costly for OEMs and their customers.  

Situation: Head Unit keeps crashing

For instance, diagnosing random head-unit crashes requires technicians gathering ECU logs in bulk at service centers and transmitting them to the OEM where engineers sift through to find the relevant data. 

This process incurs delays, costs, and customer inconvenience, all exacerbated if the issue is not detected early in post-production and leads to a mass service recall.

Detect and resolve issues early before they escalate

For faster resolution, OEMs can automate a diagnostic routine using Sonatus Automator, Sonatus Collector, ECU Monitoring Agent (ECUMA), and Log Analysis Service (LAS).    

  • ECUMA identifies when CPU usage exceeds a preset limit
  • Detection initiates an Automator workflow
  • LAS is instructed to query DLT logs for relevant data
  • Collector gathers necessary CPU metrics, related vehicle signals and DTCs
  • Bundled data is sent to service engineering and engineers notified
  • A customer support trouble ticket is created

With the precise and correlated data in hand, service engineers have a much faster path to the root cause and resolution.  Detecting issues early in post-production vehicles allows OEMs to fix them while in production or before, avoiding widespread incidents.  

Reduce mass recalls with smart, proactive diagnostics

Early detection and speedy resolution is the key to reducing the likelihood of mass service recalls.  The collection of Sonatus products described here makes it possible for automakers to efficiently assess and resolve vehicle problems before they turn into more costly and inconvenient incidents. 

  • Monitor and detect issues early
  • Automate data collection for troubleshooting
  • Get to resolution faster with precise data 
  • Apply fixes in pre-sales vehicles to avoid potential recalls
