Claim Text:
1. A system for detecting a driving state of a vehicle, comprising: a driver monitoring unit to be disposed in the vehicle, and operable to obtain real-time image frames corresponding to a driver of the vehicle; a vehicle monitoring unit operable to continuously obtain operation information of the vehicle and to provide at least one vehicle danger parameter; and a control unit coupled to said driver monitoring unit and said vehicle monitoring unit, and having a driver recognition condition, a driver danger condition, and a vehicle danger condition built therein, said control unit being operable to determine if the real-time image frames conform with the driver recognition condition and including a notification module; wherein, said control unit is operable to determine if the real-time image frames conform with the driver recognition condition based on a facial feature of the driver in the real-time image frames obtained by said driver monitoring unit, the facial feature including a facial outline, and relative positions among eyes, a nose, and a mouth; wherein said control unit is further operable to determine if the real-time image frames conform with the driver danger condition when said control unit determines that the real-time image frames conform with the driver recognition condition, said notification module being operable to provide a first notification signal when said control unit determines that the real-time image frames conform with the driver danger condition; wherein said control unit is further operable to switch from said driver monitoring unit to said vehicle monitoring unit to determine if the vehicle danger parameter provided by said vehicle monitoring unit conforms with the vehicle danger condition when said control unit determines that the real-time image frames do not conform with the driver recognition condition, receiving data from said notification module being further operable to provide a second notification signal when said control unit determines that the vehicle danger parameter provided by said vehicle monitoring unit conforms with the vehicle danger condition; wherein said control unit determines that the real-time image frames do not conform with the driver recognition condition when the real-time image frames are distorted due to one of insufficient light and nighttime driving.
