What Are the Types of Reversing Assistance Systems?

[GarrettAnn]

Reversing assistance systems can be categorized into four types based on the sensors used: infrared, ultrasonic, electromagnetic induction, and a combination of ultrasonic and machine vision. Below is a detailed introduction to reversing assistance systems: 1. Infrared: This type of reversing assistance system, which emerged in the 1980s, operates on the principle of infrared transmission and reception. Its biggest drawback is that infrared is prone to interference and is less responsive to dark, rough-surfaced objects. 2. Electromagnetic Induction: This system is based on the principle of electromagnetic induction. Its detection stability and sensitivity are significantly improved compared to infrared systems, but it can only detect obstacles dynamically. 3. Ultrasonic and Machine Vision Combination: The latest reversing assistance systems use ultrasonic and machine vision as detection methods, enabling fully intelligent parking. 4. Ultrasonic: Ultrasonic reversing assistance systems are technologically mature, offering better stability, sensitivity, and cost-effectiveness compared to previous systems. In the 1990s, reversing assistance systems finally achieved a technological breakthrough by adopting ultrasonic waves as the detection medium.
