The Parking radar today is mandatory in an optional provision of the car. They still compete with rear view camera, but for most drivers, the choice is clear – in favor of the PDC. Such systems not only help new drivers to become familiar with the nuances of driving in cramped conditions, but also save time for experienced car owners who need to quickly and safely Park. How useful will the decision on the choice of the system depends on its configuration. Perhaps the most important component of such a radar is a Parking sensor, which directly captures data about the vehicle's position relative to third-party sites. Therefore, his choice determines the efficiency of the system as a whole.

Sensor Parktronic system

The work of the PDC of the modern type is based on the principle of ultrasonic radiation, the characteristics of which determine the levels of the critical approach of the car to other vehicles, poles, the curbs, trees, etc. the Sensor in this system acts as a generator of ultrasonic waves by receiving and reflecting the pulse. Processed at the Central controller signal allows to estimate distance to nearby objects. Generally, the Parking sensor system covers a limited area, so in the singular it almost no use. The minimum set implies the existence of 2 sensors and allow maximum configuration and installation of 8 radiators on one side. The quality of the system affects not only the number of detectors and method for their communication with other system components.

Parking sensors

Parking sensors

The Main difference between the Parking sensor is the type of installation. In families large manufacturers meet the mortise and overhead models. Device mortise type, mounted in a niche in the bumper, requiring the implementation of mechanical operations with metal. To secure the manufacturers offer installation and additional accessories. For example, a Parking sensor ParkMaster modification FJ provides complete rubber damper and improved waterproofing. For models of surface-mounted type, they are attached by a special adhesive. The advantages of this installation method include elimination of need cutting of the bumper.

Different sensors and by way of signal transmission. There are wired and wireless models. The device, which are associated with the Central complex by means of transactions that are stable in the work, but the installation is not without the laying of cables. Wireless Parking sensor for obvious reasons easier to install, but many owners of these models note the influence of third-party interference on the signal transmission quality.

Sensor Characteristics

One of the key performance characteristics of the sensor is range. It determines the distance at which, in principle, be possible to commit the course. Devices with low sensitivity, have an area coverage of about 30-40 cm Premium version for this indicator can reach 120-150 cm, But this does not mean that models with a large work area more profitable. They are more suitable for heavy vehicles, and standard cars is quite suitable detector with a radius of 50 cm. Such modifications allow for less false signals and not so demanding on the power supply. However, the combined installation scheme, in which the rear Parking sensors have an increased range of coverage, and front – the same 30 see Another important characteristic is the diameter of the housing. The sensor is a very compact device, but the parameters of its design can affect future way of installation. The standard model on average have an installation with a diameter of about 16-18 mm.

How to choose the right Parking sensor?

Typically, the sensors are included in ready-made kits with a Parking radar. But at desire it is possible to include sensors from other manufacturers. For this it is necessary to assess the compatibility with the control set of characteristics of the reception signal. Next, determine the configuration parameters of the specific model – the size of the detector, shape and the presence of protective shells. It is desirable that the device had a coating that protects against dirt, moisture and mechanical shock. You should also calculate the possibility of combining with a video camera. In particular, the rear Parking sensors can go into a single installation platform matrix, which will send the video signal to the monitor in the cabin. This possibility should be envisaged at the stage of purchase. Don't ignore the aesthetic nuance. To the sensor housing is not allocated on the General background automotive exterior, it is necessary to determine in advance and with colors. In the standard version of manufacturers offer devices of silver and black colors, but there are other shades – including customized.

The Optimal number of sensors

The more you touch, the more coverage of the “blind” areas, and therefore the lower the risk of collision. On the other hand, 6-8 emitters increase the sensitivity of the system, and with it the likelihood of false signals. Therefore, the choice it is important to strike a balance dictated by the needs of the driver. Minimal kit with 2 sensors will provide for the easy movement close to the neighboring bumpers and curbs. The optimal equipment, which comes with Parking radar – 4 sensor on the rear side with 2 front sensors. In this case it will be safe to parallel Parking.

Manufacturers

The Segment is quite intense as it involves almost all firms producing electronics for cars. Leaders are companies BlackView, ParkCity and SHO-ME. It is possible to allocate Parking sensor ParkMaster, which even in budget designs has a wide coverage and reliable protection from interference. The cost of production of these brands varies from 700 to 1500 rubles on average.

Conclusion

Parking sensor system

The Success of Parking radar sensors due to the fact that the market is almost non-existent alternative solutions with the degree of efficiency. However, in the complex Parking assist there is competition between different components. To replace a Parking sensor can be an electromagnetic tape. This slip on metallic basis, which the glue from the inside of the bumper. This solution is advantageous in that it eliminates the physical mounting operation when installed and minimizes the “blind” areas in the process of operation. In turn, ultrasonic sensors win due to more precise fixation of the object in the control field.
