Body management presentation

  1. 1. Body Management Systems Presentation 14/11/08
  2. 2. Introduction <ul><li>Basic Knowledge </li></ul><ul><li>New/Changing Technology </li></ul><ul><li>Diagnostic Equipment </li></ul>
  3. 3. Topics Covered <ul><li>ABS- Anti-lock Braking System </li></ul><ul><li>TCS- Traction Control System </li></ul><ul><li>ESP- Electronic Stability Program </li></ul><ul><li>DCS- Descent Control System </li></ul>
  4. 4. Anti-lock Braking System <ul><li>Better Braking in all Conditions </li></ul><ul><li>Prevents Wheel Lock-up </li></ul><ul><li>All Road Surfaces </li></ul><ul><li>Maintains Vehicle Steer ability </li></ul><ul><li>Steer Around Hazards </li></ul>
  5. 5. How Does it Work? <ul><li>EBCM - Electronic Braking Control Module </li></ul><ul><li>Constantly Monitor the Following Input Signals </li></ul>
  6. 6. Input Signals <ul><li>Wheel Speed Sensors </li></ul><ul><li>Yaw Rate Sensor </li></ul><ul><li>Steering Angle Sensor </li></ul><ul><li>Stop Lamp Switch </li></ul><ul><li>Ignition On Input </li></ul><ul><li>Battery Voltage </li></ul><ul><li>Serial Data Communication (can-bus) </li></ul>
  7. 7. Based on these Input Signals the EBCM sends out Output Signals <ul><li>Instrument Cluster </li></ul><ul><li>Hydraulic Modulator Solenoid Valves </li></ul><ul><li>Hydraulic Modulator Pump Motor </li></ul><ul><li>Serial Data Communication </li></ul>
  8. 8. Result <ul><li>To Electronically create </li></ul><ul><li>On/Off or Hold Position of each Individual Wheel </li></ul><ul><li>When Required TO </li></ul><ul><li>PREVENT WHEEL LOCK-UP </li></ul>
  9. 9. Result <ul><li>Effective Braking System for Emergency Situations </li></ul><ul><li>WHAT A BREAKTHROUGH!!! </li></ul><ul><li>Standard Equipment- Most Makes </li></ul>
  10. 10. Traction Control <ul><li>Maintains Driver Steer ability </li></ul><ul><li>Assist/Maintain Driver Control </li></ul><ul><li>Prevents Loss of Traction </li></ul>
  11. 11. What Does it do? <ul><li>Utilizes the Active Braking Controls ABS </li></ul><ul><li>Engine Torque Reduction of the ECM </li></ul><ul><li>Prevent Wheel Spin During Acceleration </li></ul>
  12. 12. Traction Control On <ul><li>When Traction Control is Activated </li></ul><ul><li>Drive Wheel Slip is Noted </li></ul><ul><li>Whilst the Brakes are not Applied </li></ul><ul><li>the EBCM will Enter </li></ul><ul><li>TRACTION CONTROL MODE </li></ul>
  13. 13. Traction Control Mode <ul><li>EBCM Communicates with the ECM </li></ul><ul><li>Instantly Stop Vehicle Wheel Spin </li></ul>
  14. 14. How Does it Work? <ul><li>Electronically Closing Off Throttle – ECM </li></ul><ul><li>Electronically Cutting Off Engine Cylinders - ECM </li></ul><ul><li>Electronically Applying the Brake to the Spinning Wheel - EBCM </li></ul>
  15. 15. Result <ul><li>Total Driver Control </li></ul><ul><li>Standard Equipment – Most Makes </li></ul>
  16. 16. Electronic Stability Program <ul><li>Provides Optimum Vehicle Stability </li></ul><ul><li>Provides Optimum Vehicle Steering Control </li></ul><ul><li>Mainly High Speed Cornering </li></ul><ul><li>Slippery Road Surfaces </li></ul>
  17. 17. What Does it do? <ul><li>Measures Steering Wheel Angle </li></ul><ul><li>Measures Vehicle Yaw </li></ul><ul><li>Combines both ABS & Traction Control Sensors </li></ul><ul><li>Compares Sensors with Driver Input </li></ul>
  18. 18. How Does it Work? <ul><li>Reduces Engine Power- ECM </li></ul><ul><li>Applies Brakes to one, two or three Wheels </li></ul><ul><li>Momentarily- EBCM </li></ul>
  19. 19. Result <ul><li>Maintain Directional Stability </li></ul><ul><li>Prevent Under steer </li></ul><ul><li>Prevent Over steer </li></ul><ul><li>Prevent Wheel Slippage </li></ul><ul><li>All Whilst Cornering </li></ul><ul><li>NEW TECHNOLOGY - Avoid Crashes </li></ul>
  20. 20. CONFUSED??????
  21. 21. Under Steer <ul><li>Vehicle doesn’t want </li></ul><ul><li>to Turn Corner </li></ul><ul><li>Front slides out </li></ul><ul><li>Applies Brakes to one or both inside Wheels </li></ul><ul><li>Reduces throttle if required </li></ul>
  22. 22. Over Steer <ul><li>Vehicle wants to keep cornering </li></ul><ul><li>Rear slides out </li></ul><ul><li>Applies brakes to one or both outer Wheels </li></ul><ul><li>Reduces throttle if required </li></ul>
  23. 23. Information <ul><li>ESP- Electronic Stability Program </li></ul><ul><li>Mercedes, Audi, VW, Holden, Saab </li></ul><ul><li>Pegeuot, Kia, Lamborghini, Ferrari </li></ul><ul><li>Hyundai, Citron </li></ul><ul><li>DSC- Dynamic Stability Control </li></ul><ul><li>BMW, Jaguar, Ford, Mazda, Volvo </li></ul>
  24. 24. Information <ul><li>VSC- Vehicle Stability Control </li></ul><ul><li>Toyota, Lexus, Subaru, Honda, Nissan, </li></ul><ul><li>Alfa Romeo </li></ul><ul><li>PSM- Porsche Stability Control </li></ul><ul><li>Porsche </li></ul>
  25. 25. Descent Control System <ul><li>Mainly Off Road Vehicles </li></ul><ul><li>Used on Steep Downhill Slopes </li></ul><ul><li>Maintains Speed & Control </li></ul><ul><li>No Accelerator or Brake Required </li></ul>
  26. 26. What Does it do? <ul><li>Allows Driver to Drive Down a Steep Descent </li></ul><ul><li>Comfort </li></ul><ul><li>No Acceleration or Braking </li></ul>
  27. 27. How Does it Work? <ul><li>EBCM Has Total Control Over the Speed of the Vehicle </li></ul><ul><li>Constantly Activating Each Individual Wheel On/Off </li></ul><ul><li>Maintain Steady Downhill Speed </li></ul><ul><li>Normally 5km/hr </li></ul>
  28. 28. Result <ul><li>Total Driver Control </li></ul><ul><li>Total Driver & Passenger Comfort </li></ul><ul><li>Total Safety & Confidence </li></ul><ul><li>NEW TECHNOLOGY </li></ul>
  29. 29. Diagnostic Equipment <ul><li>Multimeter </li></ul><ul><li>Scan Tool </li></ul><ul><li>Any body for some Prac? </li></ul>
  30. 30. Summary <ul><li>Basic Understanding </li></ul><ul><li>Diagnostic Equipment </li></ul><ul><li>On Board Data </li></ul><ul><li>Fast & Changing Technology </li></ul><ul><li>Changes 30 years </li></ul><ul><li>Excited for the next 30!!! </li></ul><ul><li>Thank you </li></ul>
