Parking assistance is a safety auxiliary device for parking or reversing. Currently, the mainstream parking assistance system is composed of the reversing camera and the on-board display. When backing up, the display in front of the car can display the real-time video of the rear reversing camera, so as to make the backing up safer.
The secondary is composed of ultrasonic sensor (commonly known as probe), controller and display (or buzzer) and other parts.
The most common parking assistance system is the reverse parking system. Sonar sensors are also used to help the driver “see” things that are not visible in the rearview mirror, or to alert the driver to objects behind him.
When the gear bar is put into reverse gear, the reverse radar will start to work automatically. When the probe detects the rear object, the buzzer will issue a warning. When the vehicle continues to reverse, the frequency of the alarm sound will gradually accelerate and finally become a long sound.
The system can synthesize the parking route predicted by wheel Angle cutting on the real-time image captured by the rear camera of the car body.
In addition to the image, the driver can also be instructed by sound to deal with various situations in longitudinal and lateral parking.
However, the system has no auxiliary functions such as steering, acceleration and braking operations, so the driver must perform these operations himself.
