Safe driving and parking with Cadenza! February 19th, 2010

I’d like to tell you about some “pals” of Cadenza that make driving easier. The Cadenza features numerous new technologies, especially those that have to do with electronics. Technologies previously seen only in the movies are becoming reality thanks to automotive electronics. And this is probably just the beginning. In fact, the number of semiconductors in a vehicle is projected to more than double in 20-30 years’ time. Cadenza boasts many of the latest electronic technologies. Allow me to introduce two systems in Cadenza that make driving/parking fun and easy.
Lane Departure Warning System (LDWS)
First, let me ask you a question. Unfortunately, I can’t offer any prizes for giving the correct answer, but I will give you the designation of “Kia aficionado.” Shall we begin?
Q) Does Kia’s new car Cadenza have “eyes” that recognize car lanes?
The answer is yes. You might wonder if a vehicle can really have eyes that recognize car lanes. However, that is possible with Cadenza. It is equipped with a system that sets off a warning when the vehicle deviates from a lane backed by a camera that recognizes lanes in front of the car.
The warning is not triggered every time the driver changes lanes. It is activated only when the driver makes a lane change without switching on the turn signal.
The system is called the Lane Departure Warning System (LDWS). With LDWS, a camera captures images in front while the car is in motion. Car lanes are identified by analyzing the captured images. If the driver veers off from a lane without activating the turn signal, a warning light and sound are triggered to alert the driver.
If the lane on the left is marked with a yellow line, LDWS will recognize it as a center lane and two warnings sounds will go off per second to inform the driver of the risk. A serious accident could result if a car crosses over into the opposite lane, which is why we developed a system that can tell when a car slips over into the wrong side of the road.
For lanes marked by white lines, an alarm will ring once per second if the vehicle continues to step on the lane marker or deviates from its current lane. A warning will also appear on the cluster. These mechanisms prevent drivers from dozing off, a main reason for veering off a lane.
To activate the system, turn on the ignition using the push button start function and press the LDWS button on the steering wheel. Then, the LDWS image will appear on the cluster. Once the vehicle starts to move and the driving speed exceeds 60Km/hr, the LDWS will recognize and analyze car lanes to help the driver avoid risky situations.
Parking Assistance System (PAS)
I mentioned earlier that Cadenza has eyes that can look ahead. Another feature of Cadenza is the Parking Assistance System (PAS) which serves as eyes that can look at the front and back of the vehicle.
PAS uses ultrasonic sensors to detect obstacles in front and behind the vehicle. There are three different warning sounds depending on the distance to the obstacle.
If the obstacle is 1.2m away, the alarm will sound at 3.4 second intervals. The interval will shorten to 1.7 seconds when the distance is 80cm. If the obstacle is just 40cm away, the driver will hear a long warning sound.
Along with the sound alarm, the driver will see a warning light in the form of graphics appear on the cluster monitor. To provide accurate warnings to the driver, the Cadenza is equipped with a total of six sensors, two in the front and four in the rear. You can look forward to easier and more convenient parking with Cadenza.
