1 Answers
The methods to determine the 30cm distance between the car body and the corner of the garage are: 1. Judge the distance based on the rearview mirror; 2. Use the wheel position to estimate the distance; 3. Determine the distance using the parking sensors. The methods to judge the distance are: 1. When the car image occupies the entire rearview mirror, the distance is 3m; 2. When the car image occupies two-thirds of the rearview mirror, the distance is 5m; 3. When the car image occupies half of the rearview mirror, the distance is 9m; 4. When the car image occupies one-third of the rearview mirror, the distance is 12m. The method to determine the distance using parking sensors is: Judge the distance by the sound of the parking sensors. The parking sensors emit a beeping sound at a certain frequency, and the frequency increases as the obstacle gets closer. When the beeping sound becomes faster and is accompanied by a continuous tone, it indicates that the vehicle is getting closer to the obstacle.
