Parking radar, also known as front parking radar, front radar, or front obstacle detection radar, is used to detect the distance of obstacles in front of the car during parking or slow-speed driving (less than 15 km/h). It provides information about the distance, orientation, and area of obstacles and issues timely warnings, making it convenient for drivers during parking, slow-speed driving, or following other vehicles in traffic congestion, as well as helping to reduce or eliminate collisions and scrapes caused by poor visibility when moving forward. The following are the functions of parking radar: 1. Usually, radar detectors are installed on the rear bumper or both front and rear bumpers to detect obstacles in front of or behind the vehicle, helping the driver to "see" these obstacles or the distance to other vehicles when parking. Besides facilitating parking, this device can also protect the car body from scratches. 2. It uses ultrasonic sensors to detect the distance to the nearest obstacle and emits an alarm sound to warn the driver. The alarm sound control is typically divided into 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. 3. The advantage of PDC (Parking Distance Control) is that the driver can obtain information about obstacles or the distance to other vehicles through auditory signals. The PDC system primarily assists with parking, so its function will be disabled when the vehicle reaches or exceeds a certain speed.
