ELECTRONIC PLATFORMELECTRONIC PLATFORM

PSA vehicle development is now based on four vehicle platforms :

PF1 platform 1 for small vehicles

PF2 platform 2 for medium sized vehicles

PF3 platform 3 for upper class vehicles

Co-operation platform for vehicle in collaboration with other car manufacturers

The benefits of platform strategy are well known and are reinforced concerning electronics

The ultimate objective is to reach a single electronic platform

THE TARGETED ELECTRICAL/ELECTRONIC ARCHITECTURE

THE TARGETED ELECTRICAL/ELECTRONIC ARCHITECTURE

It is based on : An Intelligent Switching Unit ,so called ISU

A simultaneous optimisation of electrical architecture & electronic architecture.

That has been obtained by : Optimised partitioning of harnesses minimising number

of interconnections

Merging an increasing number of body electronics functions in the ISU

Intensive use of the multiplexing technology

1 CAN intersystem network short messages oriented at high speed for mechanical and engine functions multimasters network speed = 250 kbits/s message length allows 8 data bytes maximum (mathematical limitation)

1 VAN comfort network long message oriented at medium speed for display, dashboard, radio, climate, navigation functions ... multimasters network speed = 125 kbits/s message length allows 28 data bytes maximum (possible extension to 220 bytes)

fully matching with display equipment’s requirements.

1 VAN body network safety and/or cost effective oriented for airbags, front lights, doors, window lift, seats ... master/slaves network less sophisticated but safer typical speed 62.5 kbits /s which can be tuned for each slave node message length = 28 data bytes max. easy to add new nodes and sub-networks

In addition the diagnosis on the VAN nodes is transmitted on the VAN bus according to ISO 9141 procedures (compatible with the 28 data bytes length) to the ISU used as a gateway to transmit the DIAG on VAN to a 9141 connection

ISU SOFTWARE ARCHITECTURE ISU SOFTWARE ARCHITECTURE

Another cost optimisation consists of incorporating in the ISU an increasing number of body electronics functions

To manage the merging of different body electronics functions we had to manage also the merging of competence's of the different body electronics suppliers

In order to succeed this merging, the hardware and the software development of the ISU have been separated

The separation of the hardware and software development is very usual in the computer science field, but had never been practised by PSA previously
