The number of cars every year only grows. It’s leads to a reduction in available parking spaces, where vehicles are forced to stand tightly together. However, the ability to properly and accurately park, without hitting the nearest car at the same time, is a delicate matter, which can be handled only by very experienced drivers with many years of driving experience. To make it easier helps a special radar system, called parking assistant.
Parktronic is a special device with several radars, which is fixed on the car. It is able to calculate the distance between the vehicle and other objects. The full name of parktronics is the parking radar or parctronic system. When the device detects an unacceptable distance, it’s signaled o the driver with sound. So each car owner can react in time to the situation and make a correction of the position of the vehicle at the parking place.
Parking radar has a complex design. The main part, which coordinates its work, is the control unit. Other important elements of the system are radars, which are responsible for analyzing the position of the vehicle.
Despite the fact that the name “radar” is firmly entrenched in relation to parktronics, in fact, it isn’t s
correct. After all, these details use sound, not radio waves, and therefore should be called sonar.
In addition, the common name of this device is a parking radar, and not a parking sensor. But in Russia, the second option was fixed, since the most popular manufacturer of this electronics in the country was the company “Parktronic”, which produces similar devices for the German automotive concern Mercedes Benz. For parking radar of other brands of cars, various other names can be used.
Today there are several types of parking radar, among which:
The choice of parktronics does not depend on the brand of the car, but only on the personal preferences and financial capabilities of the vehicle’s owner.
History of origin and date of first parktronics introduction.
At a time when electronic devices to facilitate parking were not yet invented, there were already their similarities. The most effective and relevant were mechanical sensors, the so-called carbillaries. These devices were made of a thin wire or spring. They were very much like the rigid whiskers of animals to establish contact with other objects – vibrissae. The carbillers were mounted on the lower part of the vehicle. At an unsafe distance, metal “whiskers” began to scratch the curb or asphalt, while producing sounds and thus warning drivers.
Also with the help of carbilleroff it was possible to determine the dimensions of the vehicle. To do this, they were installed not on the lower part of the body of the car, but on the side corners from the front.
First time electric parktronic was developed in 1978. Its principle of operation consisted in the use of ultrasonic waves with a vibration frequency of about 40 kHz. The sensors released ultrasound, which was reflected by objects nearby. The main unit of the device analyzed how fast the ultrasound flew, and determined the distance to the object.
Few years later, in 1992, the German car manufacturer Audi released and patented its own development – electromagnetic parktronic. Such a parking radar reacts to fluctuations in the values of the electromagnetic coupling.
At the moment both ultrasonic and electromagnetic parking radar is widely used by car owners around the world.
In order to understand how it works and how to use the parking sensors, you need to understand its device.
The device of a parking radar includes:
The parking radar operates according to the following principle:
To prevent the driver from the obstacle, both sound and light can be used.
Parktronic is quite simple and convenient device, which has practically no disadvantages. Parking radar will be useful for both experienced drivers and beginners.
The following advantages of parking sensors can be distinguished:
However, there are several significant disadvantages of parking radars. The first is the probability that the device will not react to an obstacle. Usually this situation happens with such objects as:
Another significant drawback is the probability that the parking radar will produce a false signal, which not only irritates, but also distracts the driver. It can happen for a number of reasons:
Also It should be borne in mind that parking radar can not detect obstacles and objects that are “under the wheels” of the car. So, they do not notice holes in the asphalt, garbage on the road and other.
Despite some shortcomings parktronic is one of the most reliable devices for parking.
Parktronic is not an obligatory part of the car. However, most modern models from the leading manufacturers are still equipped with parktronics immediately at the factory.
More often parktronics are acquired by beginner drivers. It will help to overcome the fear of parking and driving in general. Also parking radar installs and drivers who can not “feel” the dimensions of their vehicle. Often parking sensors are equipped with cars with an elongated body, as well as all kinds of SUVs, minivans, pick-up trucks.
