THE JAM HANDELER
2

• In the modern urban world, most people spend
  hours commuting in heavy traffic.
• Time and mental energy are wasted on commuting,
  what can we do?
• The JAM HANDELER offers a solution to at least
  one side of the problem. By taking some of the
  car handling effort of the drivers, it allow them
  to relax and arrive at their destination calmer
  and less exhausted.

System Description

• The system includes 3 main parts
• The distance measuring unitmeasures distances
  to obstacles in front of the vehicle.
• The computation unit based on the measurements
  and other parameters, computes the appropriate
  response (accelerate, brake etc.).

System Description 2

• 3.The control unitcontrol the breaks, gear and
  engine. Performing the computation units
  decision.

Example Scenario

• Our driver is driving the highway on his (or her)
  way to work. As the traffic gets thick and the
  speeds go down, the system light starts blinking
  green.
• The driver pushes a button on the dash-board and
  the system takes over, the green light turns
  steady green.
• The driver let go of the pedals, but keep
  steering the vehicle.

6
Example Scenario 2

• The driver decides to switch lanes. He touches
  the pedals, overriding the system, accelerates,
  switch lanes and then takes his foot of the
  accelerator. The system takes over again.
• The traffic thins out, and as speeds go up, the
  system tells the driver to take back the control
  by an audible announcement and a blinking red
  light on the dash board.

Quality Factors

• No avoidable accidents!
• Smooth ride, at least as smooth as with an
  average human driver.

8
Technology

• Measuring unit there are two basic
  technologies radio wave based and laser based.
  Laser technology is a bit more accurate, and
  would cost 200, but not as robust. The radio
  wave technology has the advantage that some cars
  will already include it as part of their adaptive
  cruise control in the near future, and then the
  cost is 0.

9
Technology 2

• Computation unitvery low computation power
  needed. Cost estimated as lt20.
• Control unitmost modern vehicles have
  electronic engine management and electronically
  controlled braking systems, so the control unit
  will be mainly wiring the system to the engine
  and brakes.
