automotive software
Automotive Software
  • Modern cars contain hundreds of microcontrollers
    • multimedia systems
    • navigation
    • communication
    • safety

Ross Shannon: Software Considerations for Automotive Pervasive Systems

in car networking
In-car networking
  • complex sensor networks
  • communicate through a Controller Area Network (CAN)
  • AUTOSAR project for inter-car communication

Ross Shannon: Software Considerations for Automotive Pervasive Systems

componentisation
Componentisation
  • different car models will have distinct capabilities
  • modules can be replaced or upgraded
    • may add new capabilities to the system
    • software system must adapt to changes
    • opportunity for autonomics
  • software project lines

Ross Shannon: Software Considerations for Automotive Pervasive Systems

example
Example
  • GPS module
    • should be unobtrusively integrated
    • make use of existing systems within the car
      • display console for mapping
      • driver feedback

Ross Shannon: Software Considerations for Automotive Pervasive Systems

feature discoverability
Feature Discoverability
  • Opportunity for Service-Oriented Architecture (SOA)
    • services offer different Quality of Service parameters but may require use of same sensors/actuators/displays

Ross Shannon: Software Considerations for Automotive Pervasive Systems

prioritisation of inputs
Prioritisation of inputs
  • driver vs. automatic inputs
    • all inputs are filtered by the software system
    • which are more reliable?
    • software system may be taking more factors into account
    • particularly relevant as a safety concern

Ross Shannon: Software Considerations for Automotive Pervasive Systems

summary
Summary
  • system stability is critical
  • component view of systems
    • discoverability
    • adaptation
  • prioritisation of signals
