  • Potential Collision Technologies:
    • Reduce the likelihood of being in a situation in which a collision may occur
  • Imminent Collision Technologies:
    • Prevent or mitigate an imminent collision
Potential Collision Technologies
Back SMYC Forward
  • Adaptive Lighting:
    • Automatically switches between low and high beams when a vehicle isn't or is approaching
  • Adaptive Cruise Control:
    • Automatically adjusts your vehicle's speed to so that it maintains a pre-set distance (e.g., based on the driver's rule of thumb) from the vehicle in front of it
Sensors for Potential Collision Technologies
Back SMYC Forward
  • Adaptive Lighting:
    • A front-mounted digital camera with image analysis to detect oncoming vehicles (e.g., oncoming headlights)
  • Adaptive Cruise Control:
    • Sonar or radar pointed to the front of the vehicle
Imminent Collision Technologies
Back SMYC Forward
  • Forward Collision Warning:
    • Warns the driver if they are too close to the vehicle in front
  • Automatic Emergency Braking:
    • Dynamic Brake Support - Supplements the driver's braking if it is deemed to be insufficient
    • Crash Imminent Braking - Attempts to brake the vehicle when the driver does not take any action
Components of Imminent Collision Technologies
Back SMYC Forward
  • Sensor:
    • Sonar or radar pointed to the front measuring both range and speed
    • Speedometer
    • Brake sensor
  • Information Provision:
    • Visual (e.g., a light on the dashboard)
    • Auditory (e.g., a warning beep)
    • Haptic (e.g., vibration of the steering wheel)
  • Control:
    • Braking
