- A Global Standard

Magneti Marelli System and Application development with AUTOSAR

Torino, December 11th , 2008

.:. Introduction, automotive market scenario

The main drivers of today’s automotive applications are the reductions of ECU systems

cost as well as the development of new innovative functions such as: highly perceived vehicle performances, active vehicle safety, new emission laws (EU6) and CO2

reduction.

AUTOSAR Partnership is expected to play a major role by bringing OEMs, System

Integrators and Suppliers in order to reuse standardized Basic Sw solution, using Electronic Platforms “as commodity” and focalizing the interest on the development of

innovative and competitive functions.


� Scalability to different vehicle and platform variants.

� Implementation and standardization of basic system functions as an OEM and supplier wide “Standard Core” solution.

� Transferability of functions throughout network.

� Integration of functional modules from multiple suppliers.

� Maintainability throughout the whole “Product Life Cycle“.

� Increased use of “Commercial off the shelf hardware“.

� Software updates and upgrades over vehicle lifetime.

Reminder - Goals of AUTOSAR Partnership


.:. MM – XXXX----PROPROPROPRO AUTOSAR PROJECT: MM BL INVOLVED


• Answer to Customers request providing MM Electronic platforms with AUTOSAR Open SW Architecture offering the capability to integrate CUSTOMER BRAND Distinctive SW IP’s

• Provide to the Customers together with components and subsystem also the related SW control IP's

• Develop PILOT ECU Applications/Products for the MM BL involved

• Share the development of common SW modules and increase the reusability of “State of the Art” SW solutions among MM BL

• Share the SW development approach, know how and tool chain among MM BL

• Act as a “MM Virtual Factory” of Innovative SW Functions pluggable on Vehicles

using the AUTOSAR Technology.

.:. MM XXXX----PROPROPROPRO main Target


New emerging roles: Function Supplier, Function Integrator

SW IP’s sharing:

“The same control IP's (developed by OEM’s or Tier-1) could be shared between different Tier-1 with strongly reducing of design time, validation time, and application time”

• Play the new roles requested by the emerging AUTOSAR business model:

• Function Integrator: provide electronic platform with integrated customer brand distinctive SW IP’s following the required development process

• Function Supplier: Provide Control/SW IP’s distinctive of MM brand pluggable in AUTOSAR SW Architecture

.:. Electronic vs Sw development. A interesting point of view…

• AUTOSAR consortium has defined a new and profitable technology to support and manage the development of Sw ECUs.

• The clear separation between the life cycles of Sw IP’s interface and Sw IP’s behaviour facilitate reuse of Sw IP’s across different platforms

• AUTOSAR RTE does permit to realize the Sw integration phase on a interactive and testable CAE Sw environment

•... In analogy to what happened in the electronic world several years ago, some “equivalence”appear clearly evident:

• Chip Die vs SW-C-body

• Chip package vs SW-C interface

• Electronic architecture development using CAE tools vs integration of Sw application using authoring tool and RTE generation”

.:. MM Powertrain First Open Platform Vehicle (1)

• MM X-PRO AUTOSAR activities has been conducted on a demo vehicle based on new Fiat Group EU5 gasoline engine platform: “MultiAir©”.

• The MultiAir© system is an innovative Valve control mechatronic equipment able to modify stroke by stroke the admission valve phasing and opening time.

• SOP planned for 2Q 2009

Application Complexity:• Software components: around 200

• Data elements: 2650

• Data accesses: around 5000

• Calibration label: around 6000

• SW Tasks: 16

• Runnables: 624

Main System Functions:

• Variable Time and Phase Valve Control

• Emission law EU5

• Drive By Wire

• Enhanced Torque Management

• Uego lambda Sensor

• EOBD

• Digital Knocking recognition

Core: MPC 55xx family

Chipset MM proprietary


• Full EMS Euro5 Gasoline Multair Application imported on dSpace System Desk (v. 1.1).

• AUTOSAR R. 2.1- ICC1 compliant SW Architecture

• Representation of each Sw modules in term of AUTOSAR SW-C, with its

runnables, provided ports and required ports.

• Full non regression and comparative test

completed on HIL simulator using car data test drive profiles

• On vehicle driving validation @ different

environment condition, on going



• Completed the migration phase to AUTOSAR RTE, SW-components

interfaces and their integration are fully managed under SW engineering CAE

environment (SystemDesk) strongly enforcing the industrial approach to SW

development (SW quality, SW integration and consistency verification,

reducing time to market)

• A more efficient data exchange and integration between different tools has to

be realized by tools vendor


• Full SW-C Integration description, and RTE generation, compiled on target (MPC 55xx Family) @ 120Mhz:

• Delta Memory Consumption: Around 26KB of flash (~3%) and 3.8KB (~10%) of RAM (compiler Diab. 5.5.1)

• Delta CPU Consumption: First draft result of + 6-8% of CPU load @ 6000 Rpm
