IEEE Intelligent Vehicle Symposiumand Demonstration 2002

•20-21 June 2002, Versailles, France

•Demo track : 2 lanes highway with lane markings, 3400m long , curves of 30 to 80 m radii

12

• 120km/h on the straight road

• 50km/h on the curved road

• Over 100 people took a test ride.

IEEE Intelligent Vehicle Symposium 2002 Automatic Driving Demo

The film begins with a stopped empty car on the side of the road. A man driven similar car overtakes it. The empty car follows the man driven car and seems to be dragged by it. The potential applications of that technology are stop and go platooning.

A driverless car overtakes a parked car and locates with its ultra sound sensors a free parking place. The onboard computer elaborates the manoeuvre and automatically parks the car.

ROAD MAP TO AUTOMATIC DRIVING

STEP 1: Longitudinal control with variable speed set point

delivered by GPS&GIS (VSC :Variable Speed Control )

STEP 2: Lateral control (ALK :Automatic Lane keeping)

Longitudinal and maneuvers assumed by the driver.

STEP 3: Fusion of STEP1 and STEP2 with automatic lateral and

longitudinal control. The human driver assumes only supervision since we are on a free lane.

23

STEP 4: A second vehicle is added and ACC :Adaptative Cruise Control at high speed is implemented. The driver is in

charge of supervision and overtaking maneuvers.

STEP 5:Identical to STEP 4 but at low speed which necessitates the stop and go implementation (Stop and Go). The driver is still in charge of supervision and overtaking maneuvers.

STEP 6: Identical to STEP 5 but the robot is in charge of

overtaking maneuver of the slowest vehicle. The driver is only in charge of supervision.

At step 7 we have reached the level of automatic driving on highway but not yet in urban

environment.

Question Will we have driverless vehicles

one the roads one day ?

Yes We can !

Road analysis: detection of lanes, horizontal continuous or discontinuous lines and localization of the car on its lane. The film shows the robustness of the algorithm related to illumination and forks on the highway.
