Abstract: The present invention discloses a vehicle running-data recording device capable of recording moving tracks and environmental audio/video data, wherein a primary processor processes the received vehicle operational-activity signals and audio/video signals to obtain images with the acquired data embedded thereon in the form of numbers, texts, symbols, or diagrams. In cooperation with a global positioning system, the present invention can plot a moving-track diagram. The primary processor records the vehicle running status and then converts it into files and stores it in a memory. When the user plays the files afterward, he can obtain audio, video, operational-activity, and running-status information simultaneously. The connected external computer can use softwares to plot a time-coordinate vehicle running-information diagram and a space-coordinate moving-track diagram.
