Abstract: Disclosed are a display apparatus and a split-screen playback method. The method includes: upon receiving media data pushed from the terminal device, detecting a type of a current signal source of the display apparatus; in response to the type of the current signal source being included in a source list, starting a split-screen playback mode in the display apparatus, generating a first window and a second window, presenting the first window and the second window, on a display, and displaying video data from the current signal source in the first window and displaying the media data from the terminal device in the second window; in response to the type of the current signal source being not included in the source list, not generating the first window and the second window, and presenting the video data from the current signal source in a full-screen mode on the display.

Abstract: A method and system for adjusting height and damping force, the method comprising: between a first connection part (110) and a second connection part (120), arranging a pneumatic valve (130), an air spring (140), an adjustable damper (150) and a damping force adjustment device (160) used for adjusting the damping force of an adjustable damper (150), the positions of the pneumatic valve (130), the air spring (140), the adjustable damper (150) and the damping force adjustment device (160) being adaptive and the pneumatic valve (130) being connected to the damping force adjustment device (160) and the air spring (140), respectively; the pneumatic valve (130) collects at least one movement variable of the first connection part (110) relative to the second connection part (120); meanwhile, the pneumatic valve (130), according to the collected movement variable and/or the change in the movement variable, controlling the air spring (140) to inflate or deflate so as to implement height adjustment; and/or carrying out

Abstract: Upon initiating an automated parking space search and/or an at least partly automated parking process, an ego vehicle automatically provides information on at least its current position, initiation of the automated parking space search and/or a parking process, including a parking safety zone that it requires for parking, to other road users in the surroundings of the ego vehicle.
