What does 5dm mean?
1 Answers
It refers to the 5dm parking assist system. The parking assist system detects parking spaces, maps out parking areas, and dynamically plans parking paths in real-time through cameras, ultrasonic sensors, and infrared sensors installed on the vehicle body, guiding the car or directly controlling the steering wheel to maneuver into the parking spot. Relevant details are as follows: 1. Introduction to reverse radar: The reverse radar is a safety assist device for parking or reversing a car. It informs the driver about surrounding obstacles through sounds or more intuitive displays, eliminating the hassle of checking around when parking, reversing, or starting the vehicle. It also helps the driver overcome blind spots and unclear vision, enhancing driving safety. 2. How the PDC system works: Typically, radar detectors are installed on the rear or both front and rear bumpers to detect obstacles around the vehicle, helping the driver see obstacles in front or behind, or the distance from other cars when parking. Besides facilitating parking, this device also protects the car body from scratches. PDC uses ultrasonic sensors to detect the distance to the nearest obstacle and emits an alarm sound to warn the driver. The alarm sound control usually has two stages: when the vehicle reaches a certain initial detection distance, the alarm starts with a high-frequency beep, and when the vehicle moves closer to a certain distance, the alarm changes to a continuous beep to alert the driver.
