Project Overview

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 2018-11-24

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 2018-11-24

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. 2018-11-24

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. 2018-11-24

Common SW - modularity example ACCP APSS ACCP APSS BASS EVPC PLIN Acceleration pedal SWC Controls Safety Diagnostic DITD Common SW Exactly same software component can be used in different projects! EMS APSS EV Electrical car APSS HCU Plug-in hybrid car APSS Conventional car 2018-11-24

Chinese and T-engineering perspectives

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 2018-11-24

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? 2018-11-24

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?) 2018-11-24

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 2018-11-24

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!! 2018-11-24 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) 2018-11-24
