  1. EQUIP’AUTO-PARIS 13th-18th October 1999 THE NEW PEUGEOT 607 LAUNCHESPSA ELECTRONIC PLATFORM Patrick HERBAULT - Jean Michel CLIQUE – Jean Marc DHAINAUTFrançois KAAG - Jean Luc LECOCQ - André COUSTRE

  2. ELECTRONIC 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

  3. 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 numberof interconnections • Merging an increasing number of body electronics functions in the ISU • Intensive use of the multiplexing technology

  4. MULTIPLEXING TECHNOLOGIES • Historically different classes of multiplexing have been defined : • class A for low speed, master/slave low cost multiplexing • class B for medium speed multimasters multiplexing • class C for high speed multimasters multiplexing • class D for optical data link

  6. THE MAIN CHARACTERISTICS OF VAN STANDARD ISO PROTOCOL 11519-3  • Multimasters / multislaves architecture • Bitwise arbitration access method • Self clocking for slave peripherals • Fault tolerant bus driver able to cope with open or short circuit on one wire • 28 data bytes (up to 220 possible) protected by a 15 bits CRC • Broadcast or confirmed point to point communication • Deterministic behaviour through : • number of retries under control • control / command mechanism • In Frame Response mechanism

  9. ELECTRIC / ELECTRONIC ARCHITECTURE BASED ON ISU

  10. IMPLEMENTATION OF3 MULTIPLEXED NETWORKS • 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

  11. ELECTRIC / ELECTRONIC ARCHITECTURE BASED ON ISU

  12. 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

  15. THE NEW PEUGEOT 607 will launch the new PSA electronic platform  • Up to 24 electronic equipment's are interconnected through 5 electronic busses : • CAN intersystem network • VAN comfort network • VAN body network 1 dedicated to highly safety critical functions(airbag, headlights switching,…) • VAN body network 2 for the other functions(door control, seat control, fuel additivation requested by particle filter for the multi-valve Hdi diesel engine,…) • an optical data link D2B on optical fibre for large data transfer between the navigation system and the multifunction display

  17. Thanks to multiplexing, the 607 getsbenefit of the following functions :  • Ignition key with multi-function remote control, called "plip” setting automatically seat & mirrors multiple adjustments • Detection of tyre under-inflation • Automatic hazard lights operation on fierce braking • Automatic switching on of the lights according twilight sensor • Display intensity varied to suit the ambient light conditions • Radio, radiophone volume control in line with speed • Parking assistance with special mirror positioning while moving in reverse for a better view of the kerb • Automatic wiper speed control including automatically switching of the sidelights • Engine intelligent service indicator taking into account real use of the vehicle

  29. OSEK / VDX  • The open multisuppliers software architecture of PSA is based on a local Operating System which is a first step to prepare OSEK / VDX implementation • The next steps provided by OSEK / VDX will be : • first a standardised software kernel • second the evolution towards distributed functions

  30. CONCLUSIONS  The PSA electrical/electronic platform based on a set of 20 electronic equipment’s including a biVAN-CAN ISU associated to an open multisuppliers software architecture, - is launched on the new Peugeot 607 - will be deployed on the four PSA platforms
