Introduction
• According to the Kyoto Protocol, the environment related automotive regulations have strengthened.g g
• The portion of renewable energy among total energyThe portion of renewable energy among total energy will be 1%(currently, about 0.4%) on 2020 year.
• The necessity of energy-saving technology is growing y gy g gy g gstronger before developing alternative energy.
• Several leading auto-makers have studied idle-stop control device which stops engine while idling in traffic.

What is an Idle Stop Vehicle?T t f l ti d• To prevent unnecessary fuel consumption and exhaust emissions, the Idle Stop vehicle’s engine is turned off when there is no need for propulsion or airturned off when there is no need for propulsion or air conditioning.
• Conditions for Engine StopConditions for Engine Stop– Vehicle speed is less than 4km/h & the brake pedal is
pressed– Engine speed is less than 1000 rpm
• Conditions for Engine RestartA i l t d ith th l t h di d– A gear is selected with the clutch disengaged
– The brake pedal is release or the accelerator pedal is depressed with the transmission neural position

Why do we need VLC for the Idle Stop?
• To prove the effectiveness in drive, VLC is i drequired.
– More than 5% gas mileage and CO2 reduction– Release the driver’s load to fix his/her eyes on the
traffic light• For greater economy between the light and
vehicles– To send the red light interval to vehicles stopped
for the light

– Can avoid additional traffic installation

Service Scenario
• While a driver is waiting at the red light,the VIS system gets
Red Interval 50 sec.Saving Gas 15cc & CO2 14g
y gthe red interval fromthe Traffic Lightthe Traffic Lightin order to decidethe engine stop.

What is the strengths of the VIS?
• Can predict the Idling interval with accuracy- To solve the
unnecessary engine stop andengine stop and start
N d t dditi l• Need not additional equipments
