  3. daimler MISSION STATEMENT REQUIREMENTS CURRENT SYSTEM FINAL DESIGN COMPONENTS EVALUATION QUESTIONS MISSION STATEMENT Design a testing arm and active system that will simulate a vehicle for testing the collision mitigation system provided on freightliner trucks. Must meet or exceed Daimler’s list of performance requirements.

  4. daimler MISSION STATEMENT REQUIREMENTS CURRENT SYSTEM FINAL DESIGN COMPONENTS EVALUATION QUESTIONS • Must withstand a 80,000 lb truck impact • Impact speeds up to 20 MPH • Active system to minimize impact • Must be resettable • Protrude less than 12inches off of truck bed in transit • Detectable by the truck sensor • Aesthetically pleasing

  5. daimler • CURRENT SYSTEM: • Very heavy & sags • Not robust • Fails after repeated testing • Not appealing MISSION STATEMENT REQUIREMENTS CURRENT SYSTEM FINAL DESIGN COMPONENTS EVALUATION QUESTIONS
