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






Development of Hybrid control system
Sw model test simulation
environment running
Full car integration, test and calibration

Common SW – puzzle for the future
World class leading
design for modular
SW components to
be puzzled together
in a project.






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
2015-07-17

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.

Summary of Todays Hybrids





High cost (Prius 300 000 SEK)
High complexity
Depends highly on incentives
Sold with wrong motivation?
Reduced number of service facilities
Environmental friendly?

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 >150 000 SEK is out of scope. (Is this
different from Europe or rest of the world?)

东风风神 - Dongfeng Fengshen S30
Sold in China
SEK 63 000
USD 9 100
EUR 7 000
Citroen C4
SEK 120 000
USD 17 450
EUR 13 400

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.
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)
