What Does a Car's Automatic Following System Mainly Rely On?
2 Answers
The automatic following system of a car mainly relies on automatic tracking hardware and software used for data collection. Below is an introduction to active trackers and passive trackers: Active Trackers and Passive Trackers: Active trackers and passive trackers collect data in the same way and are equally accurate. The main difference between these two types of trackers lies in time. Active trackers are also known as "real-time" trackers because they send data via satellite or cellular networks, instantly indicating the vehicle's location. A computer screen can display the vehicle's movement in real-time. Passive Trackers Are More Affordable: However, they have limited data storage capacity, but they are smaller and easier to hide. Passive trackers store information on the device rather than sending data to a remote location. This type of tracker must be removed from the vehicle and connected to a computer to view the stored information.
I often go on long-distance road trips and find the automatic following system incredibly convenient. It mainly relies on the cameras and radar installed on the car to monitor the vehicle ahead, detecting distance and speed changes in real-time. Then, this data is transmitted to the car's computer processor, where software algorithms quickly calculate and automatically control the throttle and brakes to maintain a safe following distance. I love using this feature on the highway—it allows me to relax and not constantly press the accelerator or brakes, saving a lot of energy. Some systems even integrate GPS maps to predict curves, improving control accuracy. However, I’d like to remind everyone not to rely on it too much. Its performance may decrease in rainy weather or poor visibility, so I recommend regularly checking the cleanliness of the sensors to ensure the system works properly.
