We select parking radar-electromagnetic or ultrasonic?
Having a vehicle, the car owner is trying to protect it from all sorts of damage, break-ins and other unpleasant situations when using it by all known methods. This is especially true when driving in reverse or during parking time, where there is a high probability of collision or collision with objects or other obstacles. One of the most effective means of such protection are parking systems or parking sensors.
The choice of a suitable device is quite complicated, since the driver needs to decide on the type of device to be installed in the car. There are two main types of PDCs-electromagnetic and ultrasonic, and this is how to choose to get effective and long-lasting protection-quite a difficult task. Thus, we consider the main distinctive features and advantages of using each of these types of parking systems.
Features of Ultrasonic Park Assist
This system consists of a unit that processes the signal, which is often combined with an indication system by light and sound, connection wires and a sensor for detecting obstacles. The latter performs the function of generating and capturing ultrasonic waves. In the meantime, ultrasonic waves “act” with the obstacle and are returned in distorted form to the sensor. Thus, the driver can find out the distance to the barrier, after a certain signal processing.
The work of this PDC starts after the transfer of the “reverse gear”. In addition, these systems are presented in this range:
1. Mortise-for their installation you need to drill holes in the back of the body;
2. integrated-they are fastened in the handle or trunk lid, panels, other elements of the rear of the car;
3. lining, they are fixed on the double-sided tape, for their installation is not you need to drill holes or equip additional fasteners.
The number of installed sensors may be different-from 2 to 8 pcs. Traditional models are able to work with sensors that are mounted only in the back of the more expensive-with the front or side elements of the parking system.
Features of electromagnetic parking systems
This parking sensor also consists of a central control unit that processes the signal, it is often integrated with the module, which determines the distance to the obstacle and the sensor of the electromagnetic type, it is made in tape form. It is fixed to the body in any convenient place using a glue base. An obstacle is detected using an electromagnetic field and any item that falls into the area of its operation will be registered and processed in the computing unit and display.
Features and advantages of using ultrasonic parking sensors
Ultrasonic parking systems differ in their relatively low cost and huge assortment of options offered. You can pick up a parking radar with or without a display, in this case you can connect the system to a radio recorder or DVR to display information about the area in the back of the car.
In addition, motorists are encouraged to choose models with different numbers of sensors, and the more their the higher the efficiency and accuracy of the obstacle definition. In addition, there are a number of features that distinguish such parking radars from other types:
- False alarms occur when parking on an uneven surface or dirt road, near snowdrifts or sloping;
- The signal may be incorrect when in contact with fur elements. This can be a dog or a person in a fur coat, and also a rubberized post.
Also, using ultrasonic Parktronics can be traced to the emergence of "dead zones", but they can be eliminated by installing more sensors.
What is the difference between electromagnetic parking systems?
These parking systems have several significant advantages over ultrasound. They are distinguished by greater accuracy in determining the obstacles, despite the distance to it is either 2m or 5cm, and the simplicity in the installation of pactronics is also not necessary to drill the necessary parts of the body. Thus, these parking radars are more popular and in demand.
However, all in these systems have their flaws in the work, they are in the following:
- during operation, interference may occur when parktronic other electromagnetic radiation;
- there is no possibility of lowering or increasing the sensitivity, so the level of false positives is quite high;
- there is no possibility to evaluate the configuration of the obstacle, since the parking radar does not consist of of several elements, but of with one metalized tape.
Given these factors, each of these systems has its own characteristics of work. Therefore, choosing one or another type of system requires a good study of the characteristics and the design in order to choose the best option for use. A huge selection of all sorts of options and various models of well-known manufacturers can be found on our website. On it has a huge amount of parking systems of any type and configuration. On 130.com.ua you can buy parktronics in Kharkov, Odessa, Kiev with delivery in Ukraine.
The importance of using parking systems
Despite the a number of shortcomings of each type of partronik, all the the effectiveness of their work is significant. Especially they are often used by novice drivers who find it difficult to park or successfully drive a certain distance in reverse. Also, these parking systems will be necessary for owners of large cars-jeeps or SUVs, and also minibuses, other large vehicles.
In addition, it is worth considering that the incorrect operation of the parking radar may be related to:
1. sensor contamination;
2. while driving over rough terrain;
3. if there is a lot of noise in the parking lot;
4. during heavy precipitation.
Also, it is sometimes difficult for these systems to determine the presence of a cable or chains, small posts, pits or manholes. Therefore, it is worthwhile to take into account these factors while the operation time of the “reverse gear” transmission or when parking.
Having studied all the nuances of choice and the features of each type of parking systems, it will be much easier for the car owner and it is easier to decide on the choice of the appropriate type of pactronic. In addition, there are now many manufacturers and brands on the market that produce more modern systems every year, featuring much better performance and performance. Therefore, the choice is up to you.
