Detailed description of the invention
As it is shown in figure 1, be the system architecture diagram of a kind of car bulb intelligence control system of the present invention. In figure, including one-chip computer module; Its structural feature is: described one-chip computer module input connects light intensity sensor and acceleration transducer; Described single-chip microcomputer outfan connects car light automatic opening/closing module, distance-light auto-changing module, front vehicle distance light cut out reminding module, turns to safety instruction module, car light late release module.
The design of car bulb intelligence control system of the present invention with China's road traffic laws and regulations for foundation, by facilitate driver drive for the purpose of carry out. Native system has manually and automatically two kinds of mode of operations: when (1) selects manual work pattern, the control mode of light Push And Release keeps consistent with current control mode, but when light is in opening, each sensor is started working, and performs remote/low beam light switching, the prompting of front vehicle far-reaching headlamp turn-off, turns to or change lane safety prompting function; (2) when selecting automatic working method, system have light automatically turn on time-delay closing function, there is far and near light automatically change function, turn to safety prompting function, front vehicle to close the function such as high beam prompting; Also there is good Function Extension ability simultaneously, hardware has on the basis of abundant sensor, software can realize more rich function.
