  4. 4. 3 © 2018 FUJITSU Fujitsu OTA Solution - Introduction  Modern vehicles are =‘computers on wheels’  how to apply software updates easily and virtually?  New features and functions, fault fixes  For automated driving features  For fully autonomous vehicles “over the air” (OTA) update capability 50 million devices, over 10 years experience Security
  5. 5. 4 © 2018 FUJITSU What are the Benefits of OTA?  Updates can be applied at any time, without the need to bring the vehicle in to the garage  Updates to multiple vehicles applied simultaneously  New features and services can be offered and delivered  Easy and effective application of fault, error and fix management  Avoidance of costly recalls  Increase customer service, satisfaction and loyalty  Separate ‘critical component’ connectivity to that used by the car user – clarity of who ‘owns’ the update and where liability sits Car Manufacturer  Ability to authorise updates when convenient  Access to additional services and enhancements post vehicle purchase/lease and as in vehicle innovations are released  No need to schedule visits to the garage to correct faults and apply new software versions  Secure, tamper proof capability – only nominated users can authorise Car User  Capability to develop and submit updates directly  Assurance that updates are compatibility matched by OEM  Security validation and PKI certification ensures updates are not tampered with between supply and fit/application Lead Supplier
  6. 6. 5 © 2018 FUJITSU What are the Components of OTA? Our OTA solution is made up of three main component, connected capabilities: ‘Delta’ Engine Comprising central program generator and ‘in vehicle’ program installer. The Delta engine ensures an accurate picture of the current ‘as is’ component status and the status of the target update, ensuring accuracy of update application to target ECUs. 1 Configuration Manager Packages updates against target vehicles and ECUs, ensuring that update packages are compatible and are applied to the right targets in the right cars. 2 Security Manager A tamper proof and robust capability to ensure that only authorised individuals can approve and action updates, including the car user when they confirm updates can be applied. 3
