Based on the first operation, the first electronic device adjusts the first signal line to be a signal line for the first electronic device to send data to the second electronic device, adjusts the second signal line to be a signal line for the first electronic device to receive data sent by the second electronic device, and adjusts an output voltage of the first electronic device to switch the first electronic device to a power supply device.

Abstract: After a charger establishes a connection to an electronic device according to a first charging protocol, a charging circuit of the electronic device receives, in a first time period under the first charging protocol, a first power signal output by the charger, where the first power signal has a first electrical parameter; and receives, in a second time period under the first charging protocol, a second power signal output by the charger, where the second power signal has a second electrical parameter. The second electrical parameter is greater than the first electrical parameter, and the second time period is after the first time period and is adjacent to the first time period. Therefore, in a current or voltage rise phase, a current or voltage rise speed can be increased, thereby increasing the charging speed.

Abstract: An external parameter calibration method for an image acquisition apparatus is disclosed. The method includes acquiring images from images acquired by the image acquisition apparatus. The images contain reference objects acquired by the image acquisition apparatus during the driving of the vehicle. The reference objects in the images are divided into a number of sections along a road direction in which the vehicle is located, and reference objects in each of the sections are fitted into straight lines. Pitch angles and yaw angles of the image acquisition apparatus are determined based on vanishing points of a straight line in each of the sections. The sequences of the determined pitch and yaw angles are filtered. Straight portions in the road from the filtered sequences of pitch and yaw angles are obtained. Data of the pitch angles and yaw angles corresponding to the straight portions are stored to a data stack.
