What does front parking radar mean?

[LaJuliette]

Front parking radar is used to detect obstacles in front of and behind the car when parking or driving at low speeds. It provides information such as the distance, direction, and area of obstacles, and gives timely warnings. This assists drivers in parking, driving slowly, following cars in traffic congestion, or changing lanes, helping to reduce or eliminate collisions and scrapes caused by poor visibility when moving forward. The front parking radar operates on the principle of ultrasonic distance measurement. The controller directs the sensors to emit ultrasonic signals, which produce echo signals upon encountering obstacles. After receiving the echo signals, the sensors transmit them to the controller's CPU for calculation, processing, and judgment.
