  1. Advanced Powertrain ForumManagement Briefing SeminarsAug. 2, 2011 Doug Patton, Senior Vice President, Engineering DivisionDENSO International America

  2. Intro Anticipating Customer’s Needs • Key Points • About DENSO • How do we get to 50+ mpg • Beyond Powertrain • Long-term: Electrification • Mid-term: Start/stop • Short-term: GDI • Conclusion

  3. About DENSO

  4. Beyond Powertrain • Have to Look at Entire Vehicle • Aerodynamics • Mass

  5. Beyond Powertrain • Alternative Fuels • Diesel • Ethanol • Hydrogen • Bio-fuels

  6. ● Climate Control Products Automatic air conditioner, car heater, rear cooling unit, compressor, sensors, etc. ● Powertrain Related Products Engine management system, electronically-controlled diesel system, starter, alternator, radiator, etc. ● Body Electronics Products Instrument cluster, windshield wiper remote keyless entry system, IC flasher, horn, etc. Beyond Powertrain Overall Systems Approach ● Driving Control andSafety Cruise control system, airbag sensing system,vehicle stability control, antilock braking system, traction control system,etc.

  7. Beyond Powertrain • How do all the pieces fit together? • Collaboration is key • Technology tradeoffs • Weighing cost-benefits • Best systems

  8. Long-term Powertrain Advancements • How do we achieve more than 50 mpg? • Electrification • Plug-in hybrids • Extended range vehicles • Advanced hybrids • Battery electric vehicles

  9. Long-term: Electrification How Will We Get There? • Components • Cost-value • Integration

  10. Long-term: Electrification DENSO’s EV/HEV System Components Energy Power SupplySystem Accelerator pos. sensor Cooling fan B-ISG Signal Bat.

  11. Long-term: Electrification • Cost-value • Goal to reduce size and cost by 40 – 60 percent using our experience in thermal management, power electronic design and manufacturing. • Complex Component Integration • Marry or bundle technologies into a • single package or box.

  12. Mid-term: Start/Stop Technology • 35.5+ MPG 2016 and Beyond • Start/Stop Technology • Technical capability • Market acceptance

  13. ISG ECU AE starter Crank Angle sensor Alternator Electric LoadAudio etc. AT A/C ECU Vacuum Sensor 6.5% Charging Control in Sensor ＰｂBattery 4% 5.5% Charging Control 3% Engine stops when vehicle stops Mid-term Start/Stop Technology • System 1: • Advanced Engagement (AE) Starter • Not “change of mind” capable as engine needs to be at zero rpm before restart • 3% to 5% fuel savings • Existing proven technology • Simple integration MT Charging Control

  14. 7.5% 5% 6.5% Charging Control Engine stops while Deceleration Mid-term: Start/Stop Technology • System 2: • “Change of mind” capable • Restart engine before zero rpm • Permanently Engaged (PE) and Tandem Solenoid (TS) starters • Integration • Increase fuel savings potential to more than 4% ECU PE or Tandem Starter ＥＰＳ Crank Angle Sensor (Both direction) Electric A/T Pump LIN Alternator Electric LoadAudio etc. Brake System A/C ECU DDC Vacuum Sensor Charging Control in Sensor ＰｂBattery Electric W/P Cold Storage

  15. 10.5% Charging Control 7.5% Mid-term: Start/Stop Technology • System 3: • Electrical system tailored to repeated on/off cycling of start/stop systems • Overall fuel savings potential increases to more than 7% ECU PE or Tandem Starter ＥＰＳ Crank Angle Sensor (Both direction) Electric A/T Pump LIN Alternator Electric LoadAudio etc. Brake System A/C ECU Vacuum Sensor Charging Control in Sensor Electric W/P Cold Storage Power source ＰｂBattery

  16. Market Acceptance: Start/Stop Technology • Market Acceptance • Driving environment: Rural vs. City Driving • Fuel economy: Real world vs. Sticker

  17. Market Acceptance: Start/Stop Technology • Market Perception • Physical • Restart time • Occupant Comfort • Noise, vibration, harshness (NVH) • Emotional • Green • Financial

  18. Short-term: Fuel Efficiency • Gasoline Direct Injection • High-pressure fuel pump • High-pressure fuel injectors • Advanced combustion • Other Improvements: • Down-sizing • Turbo-charging • Intercooler

  19. LEVIII LEVII NMOG + NOx (g/mile) Short-term: Emissions EmissionsRequirements Year

  20. Conclusion Overall Strategy to Meet Future Requirements • Have to look at multiple solutions – under the hood and beyond the powertrain • Integration of technology • Maximize system efficiency - Cost • Quality • Manufacturing • Affordable and Appealing • Vehicles
