Title: Software Considerations for Automotive Pervasive Systems


1
Software Considerations for Automotive Pervasive
Systems
  • Software Engineering Challenges for Ubiquitous
    Computing, Lancaster, UK.
  • Ross Shannon
  • Dr. Aaron Quigley
  • Prof. Paddy Nixon
  • UCD Dublin, Ireland.

2
Automotive Software
  • Modern cars contain hundreds of microcontrollers
  • multimedia systems
  • navigation
  • communication
  • safety

3
In-car networking
  • complex sensor networks
  • communicate through a Controller Area Network
    (CAN)
  • AUTOSAR project for inter-car communication

4
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

5
Example
  • GPS module
  • should be unobtrusively integrated
  • make use of existing systems within the car
  • display console for mapping
  • driver feedback

6
Feature Discoverability
  • Opportunity for Service-Oriented Architecture
    (SOA)
  • services offer different Quality of Service
    parameters but may require use of same
    sensors/actuators/displays

7
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

8
Summary
  • system stability is critical
  • component view of systems
  • discoverability
  • adaptation
  • prioritisation of signals
