We continue with the Technical Pills dedicated to 'Lane Keeping Systems', talking about the Lane Departure Warning System fitted on the Hyundai [...]

Hyundai's LDWS system, active at speeds above the 60 km/hIt consists of a front camera/control unit positioned behind the rear-view mirror, and the dedicated activation button, located on the button panel to the left of the steering wheel.

Below is the diagram showing the system's interconnections and operating logic.

• LDWS control unit with camera: The control unit and camera are integrated into a single unit; the camera provides lane detection, while the control unit calculates the lane using the signals provided by the camera.
• LDWS on/off switch: The activation switch can be operated by the driver and also allows the last operating state to be memorised each time the engine is started.
• Instrument panel module: used for indications of operation, warnings and faults of the LDWS.
• EMS and ESP: sends information to the LDWS camera module for effective system control, e.g. engine status, wheel speed, etc.
• BCM: sends the turn signal from the multi-function switch (MFS) to the LDWS camera module. In the event of an active turn signal, the camera considers the lane change to be a voluntary change by the driver and therefore provides no warning.

LDWS control unit replacement

We would like to remind you that in the event of camera/control unit replacement, calibration is required by means of appropriate signage.

Lane-keeping control unit diagnosis

Below are screenshots of the functions that can be managed with Magneti Marelli diagnostic equipment.

Until next time...
