(Very brief) History of

NESEM 2013 Conference

automotive electronics

5

Challenge for the 2010’s • Functions-oriented design

• Architecture’s DNA • Market acceptance

NESEM 2013 Conference

6

Challenge for the 2010’s: «

Functions First »

• User/Buyer • Functions define the vehicle (not the hardware/software) • Cars have to provide « value-added » functions

• Car Maker • New functions introductions/evolutions are (too) slow • Car functions are expensive to validate

NESEM 2013 Conference

7

Challenge for the 2010’s: «

EE Architecture’s DNA »

• Power management of all actuators & loads • « Fully » connected • Full functional & evolutive platforms

NESEM 2013 Conference

8

Challenge for the 2010’s: «

Market acceptance »

• Predictible and safe behaviour • Fast to market • Cost effective

NESEM 2013 Conference

9

Pertaining issues • System architecture – System management (hierarchical) – Communication protocols • Unpredictable timing, too many redundant exchanges, asynchronous data exchanges

• Physical architecture – Disseminated sensors, cascade treatment – Actuators command and control, health monitoring – Complex harnesses NESEM 2013 Conference

Parallel and distributed processing Sophisticated synchronous algorithms Data acquisition (i.e. Sensorless) and exchange 13

Energy distribution & Control • Distributed Energy Switching Functions: – The Energy Manager (MC) monitors the health of the system – Intelligent power drivers in each node (IC) – MC and ICs, together, compose the Energy Management System
