parking sensor (PDC, Parking Distance Control) full name “reversing anti radar”, also known as “parking assist apparatus”, is a safety car when parking assistance device or reverse, by the ultrasonic sensor (commonly known as probe), and a display controller (or buzzer) and other components. The situation in reverse, helping drivers “see” the invisible things rearview mirror, or to sound more intuitive display to inform the driver of obstacles around, lifting the driver parking, reversing around, visit and start the vehicle distress caused, and to help the driver to remove dead and blurred vision sight defects and improve driving safety. Reversing radar blind spots there are some, including obstacle too low (below the center of the probe 10 ~ 15cm below the obstacle), too small an obstacle (e.g. isolated pile, oblique cable) well Goukan.

2. Reversing radar works Introduction
works
PDC system is usually in the rear bumper or front and rear bumpers of the car set up radar detectors , a time to detect obstacles in front and rear, helps the driver “see” around the side of the obstacle, or its distance from the car park, in addition to this device more convenient parking outside the body can be protected from scratching.
PDC is based on ultrasonic sensors to detect the distance from the car nearest obstacle, and issued a siren to warn the driver. The control siren sound is usually divided into two stages, when the distance of the vehicle reaches a certain distance from the start of detection, siren sound startIn a high-frequency siren beeps when reaching a closer distance, the siren changed to continuous sirens, to inform the driver. PDC advantage is that the driver can obtain information about the auditory obstacle, or distance that the vehicle glass. PDC system is mainly to assist parking, so when it reaches or exceeds a certain speed the system will be turned off. .
3 optional reversing radar Notes
1 quality: as a reversing radar automotive supplies, the most important is to see whether its quality longer perfect, better quality products and services offered, promised repair period.
2 functions: the function to distinguish, can be divided into LCK reversing radar distance display, voice prompt alarm, position indication, voice prompts, automatic detection probe, a fully functional radar reversing should have these Features.
3 Performance: The performance mainly from the detection range, accuracy, stability, and display the captured target speed research. The detection range of at least 0.4 meters to 1.5 meters between; accuracy mainly depends on two aspects, first look at the display resolution, typically 10 cm, 1 cm to achieve good, followed by detection errors see, i.e., the distance between the display and the actual distance error detection errors good product less than 3 cm; refers to show stability under a bad surface reflected by an obstacle, the ability to capture and display a stable distance between obstacles; capture reflects reversing radar target speed moving objects capture capability. Reversing radar performance requirements are: measured accurately measured steady, rapid capture a wide range and speed.
4 outerWorkmanship concept: as decorative pieces inside and outside the car, the car needs and the overall structure, color coordination.
4. Rear radar Details
1 after reversing radar automotive parking assistance device or the safety during reversing, by the ultrasonic sensor (commonly known as probe), and a display controller (or buzzer) and other components. Or can be displayed in a more intuitive voice informed of the situation of obstacles around the driver, the driver lifted parking, all around to visit the distress caused when reversing and start the vehicle, and helps the driver to remove dead and blurred vision of defects and improve driving safety.
2. Rear radar probe mounted in the rear bumper, the probe radiation at an angle of approximately 45 degrees, up and down search targets. The greatest advantage is to be able to explore those obstacles below the bumper and the driver is difficult to see from the rear window, and the police, such as flower beds, children playing after squatting on the car and so on.
3. When the reverse gear shift lever engaged, reversing radar automatically start working when the probe detects objects behind the alert buzzer, when the vehicle continues to reverse, the frequency of an alarm sound will gradually accelerate and finally becomes a sounding tone.
