Parking sensor. The parking sensor, also known as the "reverse parking radar" or "parking assist system," primarily consists of ultrasonic sensors, a controller, and a display. Relevant details are as follows: 1. Ultrasonic sensors: Their main function is to emit and receive ultrasonic signals, which are then transmitted to the main unit and displayed on the screen. 2. Controller: It processes the signals to calculate the distance and direction between the vehicle and obstacles. 3. Display or buzzer: When the sensors detect that the car is at a hazardous distance from an obstacle, the system alerts the driver through the display and buzzer.

That symbol represents Audi's Park Assist parking aid system. I remember when I first drove an Audi and saw it, I thought it was some mysterious button. Actually, it's designed to automatically operate the steering wheel during parking, helping you easily park into a space. After pressing it, the car uses sensors to scan the surrounding space size, then automatically steers - you just need to control the speed with the brake. As a driver who frequently takes long trips, I find this feature extremely practical, especially in crowded mall parking lots where it eliminates the hassle of manual reversing. It also helps prevent scraping against other cars, boosting driving confidence. Modern automotive technology advances so quickly that even parking can be handled intelligently. Audi's design is quite user-friendly, benefiting both novice and experienced drivers alike.

This thing represents Audi's automatic parking assist feature. When you're driving, press that P with a triangle button, and the system will activate: it uses onboard radar or cameras to detect nearby parking space dimensions, then calculates the trajectory for automatic steering. You just need to monitor the accelerator and brake pedals. I've studied these systems - they combine sensor technology with driving assistance, aiming to simplify the parking process. No manual steering wheel turning is required during parking, making the procedure more efficient and safer. Tech enthusiasts will definitely appreciate this innovation as it reduces collision risks caused by human error. In the future, such features will become increasingly common as standard equipment. Audi is truly at the forefront of intelligent technology.

As a safety-conscious person, I always feel reassured when I see the P with a triangle symbol on an Audi. It signifies the Park Assist function, which is incredibly helpful during parking. The system monitors surrounding obstacles and automatically controls the steering wheel movements to avoid hitting walls or scraping other vehicles. This feature is especially beneficial for novice drivers, as it significantly reduces the likelihood of accidents. You simply need to press a button to activate it, and the gear shifting operations are mostly automatic, allowing you to focus on the road conditions. I frequently use this feature when driving my Audi in the city to ensure smooth parking. This function is an extension of the vehicle's safety system and deserves to be promoted across all car models.
