Tool Reviews

Parking a car is one of the most difficult tasks for a driver. Parktronics help both beginners and more experienced car owners cope with this operation.

Device and principle of operation

The design of the parttronic consists of an electronic unit, sensors and a warning or image mechanism. The device consists of several sensors built into the bumper of the car.

The action of the product is based on ultrasonic or radio waves. Sonars measure the distance to surrounding objects using a signal, reflect off obstacles and transmit information to the parking sensors.

The distance is calculated based on the time it takes the pulse to travel its path and the speed of sound.

There is a limitation in distance measurement. The target is determined from 25 to 180 cm. The bumper sensor is activated simultaneously with the reverse, and the front sensor is triggered when the gas pedal is pressed.

Purpose and functions

Purpose:

• The device helps to park the car by detecting an obstacle from different sides.
• Makes driving through narrow spaces safe.

Functions:

• Digital indicator. An alert about the distance to the object is shown on the display.
• Voice notification. This option extends the signaling characteristics. Some models report data at some intervals, while others indicate the side of the sensors.
• Memory features of automotive elements. The program takes into account external elements on the bumper: spare wheel, towbar, grille and others.

• Video output to the camera. A special connector connects the parking sensors to the rear view camera. This guarantees constant monitoring of what is happening: the camera shows what is covered by the rear-view mirrors. Some products include a monitor.

How to choose a parktronic

Important parameters:

Scan area

Each parking sensors model scans a certain area of ​​the surrounding space.

• Back view. Parktronic scans the area behind the car. This option is inherent in all models, and for some it is the only overview.
• In the front and in the back. This coverage guarantees maximum protection when performing maneuvers. Although you can see well from the front, sometimes there are low obstacles that remain out of sight. Actual function for high cars.

Installation method

• Wired. Component parts (sensors, control unit, display unit) are connected by wires. The design is cheaper, but difficult to install, since wires from the rear sensors to the screen are passed through the interior.
• Wireless. Signals are transmitted by radio band. The user installs the main unit in the trunk, and there is no need to pull wires to the display.
• Mirror overlay. Models are installed in place of the rear mirrors with an additional block or directly on a stationary mirror. It is convenient that the place of installation is determined in advance.

Data output method

• Sound. As you approach the object, the signals become more frequent, and in case of danger they become a continuous squeak. Such models are the cheapest, but the accuracy of the information does not guarantee full parking, it is more of a safety option.

More often, an external monitor is connected to such models.

• Led bulbs. Indication occurs using a set of LEDs, which are displayed on the screen in the form of dots or rectangular blocks. As an obstacle approaches, their number increases.
• Display. The image is displayed on the screen: in large print or a graphic picture; video from a camera installed behind the car.

Secondary options:

• Volume control. The sound is adjusted at the discretion of the user, so as not to miss the notification due to noise, or, conversely, not to create it.
• Rear View Camera. If the package includes a camera that is compatible with the device, then the installation of equipment is easier for the user.
• Number of sensors. As a rule, two devices are equipped in front, the review is often not difficult. Some models are equipped with 4 sensors. From 2 to 8 sensors are mounted behind.
• Measurement accuracy. The parameter refers to the distance measurement error. With an indicator of 5 cm, the distance, for example, is from 20 to 25 cm. All models are characterized by an error, but the smaller the value, the more accurate the readings.

• Operation threshold. Standard products respond to objects from 1.5 to 2.5 meters. This is quite enough for safe parking. The minimum threshold is from 10 to 30 cm.
• Video output to external devices. A GPS or car TV is connected through a special connector. The screen displays information on a larger scale than in the built-in indicator.

The best parking sensors are characterized by the following elements:

• The signal range starts from 2 meters. If an object is approaching, the device will notify you.
• performance.
• The installation location on the rear mechanism mirror is considered more practical for drivers.
• The self-diagnosis option automatically checks the working condition of the sensors, and in the event of a breakdown, it will notify the user.
• High resistance to environmental conditions. Functioning at the same level in rain or snow, dust, fog.
• Ready kit for installation. The product set includes sensors, wires or other necessary items.

• A rear view camera will help in parking large cars, but there is a caveat: if it gets dirty, the device will not be useful.
• The disadvantage, which is typical for all parking sensors, is a kind of limited visibility. Large objects fall into the attention of the device. But if a metal pin protrudes from the ground, the device will not catch such an obstacle.
