Software Considerations for Automotive Pervasive
Systems

• Software Engineering Challenges for Ubiquitous
  Computing, Lancaster, UK.

• 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
