Abstract: A wireless charging device is disclosed, which includes: a charging pad and a first controller. The charging pad includes a plurality of charging units, the plurality of charging units include a first charging unit and a second charging unit. When a first electromagnetic coupling strength between the first charging unit and the to-be-charged device is greater than or equal to a first threshold, the first controller is configured to control the first charging unit to separately charge the to-be-charged device. When both the second electromagnetic coupling strength between the second charging unit and the to-be-charged device and the first electromagnetic coupling strength are less than a first threshold, and are greater than or equal to a second threshold, the first controller is configured to control the first charging unit and the second charging unit to jointly charge the target to-be-charged device.

Abstract: A map updating method and apparatus (800), and a device (900) are disclosed, which can be used in automated driving (Automated driving), intelligent driving (Intelligent Driving), and other fields. The map updating method includes: when an abnormal scenario occurs, obtaining various types of sensing data of the abnormal scenario, calculating a minimum safety boundary based on the sensing data of the abnormal scenario; and updating a map based on the minimum safety boundary obtained through calculation. According to the map updating method, a map updating program can be triggered when the abnormal scenario occurs, without the need to wait for a collection vehicle/crowd-sourcing vehicle. This improves real-time performance of map refreshing, and ensures safety of an automated driving environment.
