A few days ago, during the automatic parking process, the front of the passenger car and the pillar of the parking lot were scratched, but the system did not find any abnormality, and finally the vehicle was automatically parked in the parking space when the front bumper was hit.In response, Zhiji Auto’s official social media posted that after the accident, it has negotiated a solution with the user and sincerely apologized to the user. It will optimize the ability of automatic parking to cope with vulnerable scenarios and push the landing through OTA upgrades. Wang Kang, the head of the smart driving team, said that it will bear the maintenance cost of this customer at its own expense.

　　Regarding the cause of the accident, the official preliminary technical analysis is as follows: In this accident scenario, the thin pillar is an "I" shaped metal structure, and the size is too small; resulting in insufficient position accuracy of obstacles constructed by on-board ultrasonic radars, cameras and other sensing sensors, resulting in scratches between the vehicle and the metal thin pillar. For similar weak scenarios of automatic parking, Zhiji has collected a large number of thin pillar scene data for model training, and synchronously and quickly iterated the fusion sensing algorithm with more stable performance. Through the latest simulation evaluation, the detection ability and detection position accuracy of metal thin pillars in similar scenarios have been greatly improved; after further optimization and verification, it will be upgraded and pushed through OTA.
