Modern drivers have an excellent opportunity.use various electronic assistants that make driving easier. To park the car safely for themselves and others, there are parktronics. Installing such a device is a simple process, and with the help of detailed instructions, everyone can do it in the garage with their own hands.
Operating principle
Works parking assistance system on the baseprinciple of ultrasonic wave and echolocation effect. The sound wave, which is radiated and received by special sensors installed in front and behind the car, is analyzed by the control unit of the device.
По тому, сколько времени потребовалось волне, to reflect from an obstacle, the distance from it to the car is calculated. The zone in which the device can operate as efficiently as possible depends on the manufacturer and the technical characteristics of one or another PDC. For most devices on the market today, this zone ranges from 0.2 m to 2 meters.
Design
The system is a set of sensors.control unit device to display information about the distance to the obstacle. The systems also have a sound signal. Some models include a rearview camera and other useful options.
Главным в конструкции парктроника является блок management. It is he who analyzes all the information contained in it and then generates electronic impulses for supplying visual and sound signals. Their intensity will grow as the car approaches another car or an obstacle on the way. Depending on the model, information may be fed to the LED panel or LCD display.
Ультрасовременные модели оснащены проекционной system, thanks to which all the information is conveniently projected on the windshield. The sound alert is in most cases a pleasant female voice.
Types of devices
The installation scheme of parking sensors depends on the type of sensors. At the moment there are several types of these elements:
- acoustic;
- electromagnetic.
Each of them has its own characteristics.
Acoustic parking sensors
Эти системы являются самыми популярными на рынке.There are lots of devices that use ultrasound for work. They may differ from each other in the number of sensors, the method of presenting information, the presence of additional options.
The best option is four sensors forFront-mounted, as well as two for installation on the rear bumper. In order to eliminate such an effect as “dead zones”, it is recommended that the sensors be installed over the entire surface of the bumpers when installing a PDC of this type. The distance between the elements should be 40-50 centimeters.
The more sensors included, the more accurateoperates parking sensors. However, this type of system is characterized by large errors in the process. A common disadvantage of the group of these devices is that they are not able to detect obstacles that are not above the level of the road. Parktronic can give false signals on the slopes, as their surface falls within the range of its sensors.
Electromagnetic devices
This type of car parking system is nothas separate sensors. A special tape is used here as sensors. It is necessary to fix the inside of the bumper. This mounting technology is much simpler, since there is no need to drill holes for installing sensors.
As for the principle of operation of these systems,they work as follows. An electromagnetic field is created around the car's bumper. Any items that fall into it, change its characteristics. At the slightest change in parameters such as field density, intensity or zone of induction, the control unit immediately sends a signal to warn the driver.
Так как в данных решениях работают принципы magnetism, such tape Parktronic more accurate. They are able to track those objects and obstacles in the way that ultrasonic counterparts cannot cope with. But often due to bad weather conditions or external interference, the efficiency of the electromagnetic field decreases.
Self-installing
Installing a full-time parking sensor is not a task that is worth going to the service station. With minimal effort, everything can be done independently. Let's look at how to do it.
In most cases, as a parkingRadar acquired traditional devices based on acoustic sensors. The entire installation process is reduced to the fact that it is necessary to drill holes in the bumper, then install the sensors, and then paint the bumper in its factory color. There should be no problems with drilling, although the process can take a long time. Complete with sensors and parking sensors, there is a special cutter.
It is important to carry out the markings correctly so that during operation they do not receive signals from the sky or from the road surface. Included is a manual, but it is not adapted for different cars.
Markup
For standard parking radar from China (andIt is this kind of car electronics that is bought most often. The height of the capture zone varies from 48 to 54 centimeters. At critical distances (up to 30 cm), this height is 44 centimeters, and at large distances - 51. This zone is a cone: its top is on the sensor, and the sides extend from the car. Based on this data, it is necessary to calculate where the sensors should be installed.
For the device to work properly, for startersIt is necessary to measure the length of the bumper. First, consider the installation of rear parking sensors. The length of the bumper should be divided by 8 - this distance is measured from the left and right edges of the element. Then you need to calculate the location of two more sensors, for this the length of the bumper is divided by 4. The result is the distance that you need to retreat from the extreme sensors to the center of the bumper on both sides. This will be the installation point of the rear parking sensors.
Height from ground level is from 50 to70 centimeters depending on the type of car. This is the most optimal figure. Places under the sensors can be marked with a pencil or marker. There are usually two holes in the front. They are calculated similarly.
How to drill holes?
There are no special problems.Holes must be made at low speed and low feed. If this advice is not followed, there is a risk that the bumper material will melt and as a result uneven holes will result.
При установке парктроника своими руками многие will be used for drilling holes cutter or drill that comes in the kit. But there is an important point. The drill or cutter has a diameter equal to the diameter of the sensor. But when installing, squeeze the silicone clips can be a daunting task. Therefore, in the place where they are inserted, the hole expands literally by 0.5 millimeter.
Wiring
Шнуры собирают в один жгут для компактности.Then it is necessary to intercept the ties. Sometimes there is a box in the kit - you need to place the cable there. Next, the wires gently pull on the body under the decorative trim. To secure them, apply the screed.
The control unit is mounted in the front area.car dashboard. It is easily glued to velcro. They are on both sides, even on low-cost models. Then mount the display unit and warning system. It is better for this to apply the manufacturer's instructions. The audio signal is placed closer to the driver. Displays are mounted in the area of the speedometer or near the left rack.
Connection
You can connect the system to the rear lights - theywill run in pairs. Connectors must be connected carefully. Very comfortable when installing sensors PDC use special connectors, rivets. They make contact by poking the cable.
“Kia” and parking sensors
On various models of this manufacturer isthere is no useful device among the standard equipment. Therefore, the installation of PDC on the "Kia" - is the ability to save the taillights and front optics.
For installation, you need a screwdriver, screwdrivers,insulating tape, soldering iron, strips. First of all mark the place of installation. To do this, stick a strip of masking tape over the slice on the rear bumper and mark the points where the sensors will be installed. You can use the instructions that comes with the specific model of the device.
Further, using a screwdriver and a complete cuttermake holes. Work should be very careful not to damage the bumper. Installation of front parking sensors is carried out according to the same algorithm.
Next, remove all the plastic trunk.It simply stretches up and out. As a result, a hole will appear through which you need to stretch the wires of the sensors, collecting them previously in a bundle. When this is done, the plug is returned to the place.
Then install the display device.It can be hung under the roof or mounted on the dashboard. Wires are laid through the ceiling and brought to glass. To remove the trim on the side posts, you need to dismantle the door seal and pull the upper edge towards the center. Next you just need to pry the retainer.
Then dismantle the left side of the trunk.Install the control unit and connect all the elements. Power is better to apply through the cable, which runs in the upper part of the trunk and goes to the roof on the left side. We need a white and orange wire - this is a “plus”, black - “minus”. All connections are carefully insulated.
Installation is complete, it remains only to assemble the interior, after which you can check the operation of the device.
“Ford”
Unlike Kia cars, installationParktronic on the “Ford” is simplified by the fact that there are factory holes. They are made on the lining of the rear bumper to accommodate the sonar. But despite this, the holes are very rarely used. This can be easily explained: the pad comes from the factory unpainted, which means that the sensors will stand out greatly. Factory openings are above the level recommended by manufacturers of PDCs.
They are provided for the installation of regular Parktronic, available, however, only in expensive models. And if there are none, then the installation is carried out according to standard technology, but without markup.
“Reno”
Installation is carried out according to the instructions.From the opening of the room, the first sensor must be set at a distance of 3 centimeters, and the second - at 37. Here the main accuracy. From the edge of the machine for different models, it is recommended to retreat 20-30 centimeters. Next, drill holes in the bumper and remove the rear lamp. The sensors in the holes set according to the letters: R - right, L - left. Then all the wires are collected, tied into a bundle and pushed under the bumper amplifier. With the help of wire harness pushed further between the bumper and the lantern.
As for the connection, then to the green wireconnect the positive contact on the control unit, and the negative - to the mass. It remains only to stretch the wires through the cabin, and then proceed in the same way as described above. As you can see, the installation of parking sensors on the "Renault" - this is a simple process that everyone can handle.
