11. Project Overview

12. PHEV project Production capabillity without SOP
Hybrid control and DCT control
EV drive, hybrid mode and normal car
Full AUTOSAR 3.1 SW plattform on target
Functional safety according to ISO26262
6 months from start of development to runnable DFM PHEV S30 car with rapid Pro system, another 6 month on target HW
PHEV car in Shanghai motor Show April 2013

13. ISG project Development of Hybrid control system
Full car integration, test and calibration
Full Test & simmulation MIL and HIL running
Full production verification.
Full AUTOSAR SW plattform on target
Safety according to ISO26262
Sw model test simulation environment running
Automated
Hardware In the Loop
test environment running

14. Common SW – puzzle for the future
Modular control strategy architecture
Based on physical models
Maximizes re-usability
Minimize testing and fault tracing
Enables fast to market project
ISG and PHEV project has shown the benefits of common SW
Possible to use software components independently due to Autosar design
Functional safety designed according to ISO26262
World class leading design for modular SW components to be puzzled together in a project.

15. Common SW - functional view
The design is made acording to a physical flow. That flow has been choped up into small pieces that can be allocated seperatly to form a flexibel and modular system that can be adapted into many different types of controls systems.

17. Chinese and T-engineering perspectives

18. The Prius Was Released 1997 Full hybrid 2 Electric Motors eCVT
30kW NiMH Battery
Very Low Cd
Electric AC
1.8L ICE
A few limitations
More or less this is the same vehicle even today

19. Summary of Todays Hybrids
High cost (Prius SEK)
High complexity
Depends highly on incentives
Sold with wrong motivation?
Reduced number of service facilities
Environmental friendly?

20. New Energy Vehicles for “Zhang San” China Market
15.5 million passenger cars sold 2012
The Chinese middle class is growing quickly
First car buyer – little reference
Huge emission problems already today
Purchasing a vehicle > SEK is out of scope. (Is this different from Europe or rest of the world?)

21. 东风风神 - Dongfeng Fengshen S30
Sold in China SEK USD EUR Citroen C4 SEK USD EUR

22. Hybrid System Content Combustion engine – Increased
Chevrolet, Toyota, Ford
Combustion engine – Increased
cost due to low fuel consumption
and emission demands
Automatic gearbox needed
High Voltage Battery
Electric Motor(s)
Power Inverter(s)
High Voltage Cables/Connectors
Auxiliaries
Extra HW = Extra COST!!
El. AC, Heaters, vacuum pumps etc.

23. Development of New Energy Vehicles for “Zhang San”
Challenge
Low complexity
Fewer components
Lowered requirements
Low cost
But Software is for free (At some point)
