What does the button with a P and three slashes in a car represent?

A button with a P and three slashes in a car represents the parking sensor. The parking sensor can also be called "reverse anti-collision radar" or "parking assist device." The parking sensor is a safety driving assistance device designed to help drivers understand the surrounding obstacles during parking, reversing, or starting. During use, it alerts the driver through sound or other means. Therefore, during parking or reversing, you may hear warning sounds, which indicate that the parking sensor has detected an obstacle. However, some cars have a P with two slashes instead of three, which is also the button for the parking sensor. Additionally, some cars do not have an automatic parking function, so the specific functions of the buttons on different car models can only be known through actual operation by the driver. The parking sensor consists of ultrasonic sensors (commonly known as probes), a controller, and a display (or buzzer). It informs the driver about surrounding obstacles through sound or more intuitive displays, eliminating the hassle of checking front, back, left, and right during parking, reversing, or starting the vehicle. It also helps the driver overcome blind spots and unclear vision, improving driving safety.
I've driven several cars with this button—the one marked 'P' with three small lines next to it. It's actually the electronic parking brake switch, super practical with one-touch operation. After parking steadily, just press it to lock the car in place—no worries about rolling downhill. Press it again before driving to release, effortless and much lighter than old-fashioned handbrake levers. It saves space and keeps things tidy. I often use it when parking on mountain roads—feels super reliable, and the dashboard light confirms activation. Just never press it randomly while driving, as it could lock the wheels and cause danger. Once you get used to it, I think all modern cars should have it as standard—convenient and safe.
I noticed this button with a P and a slash symbol on my car. After researching, I learned it's part of the Electronic Parking Brake (EPB) system. Instead of using a manual lever, it controls the brakes through electrical signals. The advantages include high integration and automatic release when paired with automatic transmissions. For example, it releases when shifting to D gear after starting, preventing forgotten brake release and vehicle rollaway. I think it's a clever design that reduces mechanical failure risks, though electronic component failures could mean more complicated repairs, so regular maintenance checks are important. Overall, it enhances driving convenience and vehicle intelligence.
