Product name one

  • FRONT PARKING SENSOR, also known as front parking radar, front radar or front radar, is used to detect the distance of obstacles in front of the car when driving in a car or slow (less than 15 km / h), providing obstacle distance, bearing, Area and other information, and timely alarm, to provide convenience for drivers to park, slow-travel or congested with cars, parallel lines, etc., and help them reduce or eliminate collisions and scraping accidents caused by poor line of sight during advancement.
  • 产品详情

The performance of the front parking radar mainly includes the detection range, accuracy, display stability, etc., especially the farthest detection distance, which must be far enough.

D.1 Detection range

Most products range from 35cm to 120cm, and good products can reach 35cm to 260cm. A wide range of front parking radar can detect the target as early as possible, so that the driver can predict in advance and prevent it as early as possible; and excessive pursuit of the minimum detection distance is meaningless, because the inertia factor during braking must be fully considered in actual use.

For the car front bumper shape is more complicated, the installation of 4 sensors can not cover the entire detection area, the blind area is too large, should consider the choice of the front 6 parking radar.

D.2 Accuracy

Mainly look at two aspects.

First, look at the resolution of the display, the general product is 10 cm, and the good product can reach 1 cm, without the distance display, only the buzzer products can only know the obstacle area according to the alarm sound rhythm;

The second is to look at the detection error, that is, the error between the display distance and the actual distance. The PVC tube with a diameter of 10 cm can be used to measure the sensor at a distance of about 100 cm. The detection error of a good product should be less than 2cm.

D3. Display stability

It refers to the distance between the obstacles when the obstacle surface is not good or during the driving process, and the obstacles can be stably displayed when the obstacles are detected. For the external disturbance sources such as car horns, brakes, high-speed sound noise, etc. during driving, See if it can be effectively suppressed, the display does not appear to be chaotic.
