Lane Departure Warning System Introduction

The system automatically triggers when the driver unconsciously deviates from the original lane.

The LDWS system works as follows: When the vehicle crosses the road sign (indicated by the white lane) without turning the turn indicator light, the infrared sensor behind the front bumper can detect this action and trigger the ECU to pass the driver's seat according to the direction of the deviation lane. The left or right side of the chair vibrates to alert the driver. This will allow the driver to take immediate action and return to the original driveway.

The system is activated by a button on the center console and remains activated after the engine is turned off.

In order to detect unintentional lane departures, the LDWS system has six infrared sensors behind the front bumper, three on each side. Each sensor is equipped with an infrared light emitting diode and a light detection slot. The system detects lane departures by detecting the infrared beam of the LED and the change after reflection on the road surface.

The sensor detects white lines and temporary pavement markings in yellow, red and blue used in some European countries. The system identifies lines (continuous or discontinuous) as well as other road markings such as direction markers.
