Automatic parking refers to the capability of a vehicle to park itself without manual control, making it a boon for drivers. Despite this convenient technology, why are people not very willing to use it? The specific reasons are as follows:
Accuracy of Parking Spot Recognition:
Although automatic parking can free up the driver's hands, it has a significant flaw – the accuracy of recognizing parking spots. It primarily relies on multiple radar sensors to judge the distance from obstacles. If obstacles are suspended in mid-air or have a low height, the radar sensors may not detect them, leading to potential friction or collisions.
Speed Control Accuracy:
The accuracy of speed control in automatic parking is also lacking. Even if the radar sensors accurately detect obstacles and react in advance as contact becomes imminent, the inability to precisely control vehicle speed in real situations may result in inertia-induced collisions with obstacles.
Activation Complexity:
Activating automatic parking can be cumbersome. The vehicle needs to be in Drive (D) mode, and the driver has to simultaneously control the vehicle while watching the central display screen to assist in recognizing parking spaces for the system to work.
Differences Between APA and AVP Automatic Parking:
Level of Intelligence:
APA (Automated Parking Assist) is a first-generation automatic parking technology that requires driver assistance inside the vehicle to complete the parking process. In contrast, AVP (Automated Valet Parking) is a fourth-generation automatic parking technology that enables remote operation by the driver from within 500 meters outside the vehicle. AVP can autonomously search for parking spaces, park, and, when needed, exit the parking space and drive to a location specified by the owner.
Autonomous Driving Level:
APA is classified as a level 2 autonomous driving system, while AVP is a level 4 autonomous driving system.
Sensor Layout:
Compared to APA, AVP automatic parking is equipped with four fisheye cameras, providing a 360° panoramic view. Additionally, AVP can use onboard Bluetooth for control.
