US patent 8423235, titled "Video recording device for vehicle and driving information providing method thereof," was granted to MtekVision Co Ltd.

Here is a summary of the patent:

• Title: Video recording device for vehicle and driving information providing method thereof
• Assignee: MtekVision Co Ltd
• Inventor: Kam-Youn LEE
• Filing Date: 2010-09-13
• Issue Date: 2013-04-16
• Abstract: The patent describes a vehicle video recording device and a method for providing driving information. The device comprises a sensing unit (with a positioning unit, inertia sensor, and/or environment sensor), a vehicle information collecting unit (collecting data from vehicle sensors or a self-diagnosis device), and a driving information generating unit. This unit generates driving information based on the sensed and vehicle information, distinguishing between vehicle use and non-use. This allows for continuous management of vehicle driving time or accident possibility, potentially offering advantages or disadvantages to the driver.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Vehicle Video Recording Device): This claim describes a vehicle video recording device designed to record outside video. It includes:

  • A sensing unit that provides "sensed information." This unit can contain a GPS for position, an inertia sensor for movement, and/or an environment sensor.
  • A vehicle information collecting unit that gathers "vehicle information" from the car's own sensors or a self-diagnosis system (like an OBD device).
  • A driving information generating unit that creates "driving information" based on the sensed and/or vehicle information. Critically, it generates different sets of driving information depending on whether the vehicle is in use or not.
    • When the vehicle is in use, the first set of driving information includes things like the driving date, distance traveled, speed, turn signal activation, seat belt use, acceleration pedal input, brake signal, remaining fuel, and fuel consumed.
    • When the vehicle is not in use, the second set of driving information includes at least the traveling distance and GPS coordinates.

• Independent Claim 9 (Driving Information Generating Method): This claim outlines a method performed by a vehicle video recording device to generate driving information. The method involves:

  • Acquiring vehicle information and sensed information using vehicle sensors or a self-diagnosis device.
  • Generating driving information based on this acquired information, differentiating between vehicle use and non-use.
    • When the vehicle is in use, the first set of driving information includes details such as driving date, traveling distance, speed, turn signal, seat belt usage, acceleration pedal, brake signal, residual fuel, and ejected fuel.
    • When the vehicle is not in use, the second set of driving information includes at least the traveling distance and GPS positional coordinates.
