For those who missed it the previous time....here is the second part on lane keeping systems.

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...
