Video camera or photographic head carry out recording to environment inside car in real time and obtain.
Such as, central processing unit periodically obtains, by vehicle bus, the illumination that optical sensor gathers in car
Intensity.Then, central processing unit by acquired intensity of illumination is compared with preset Intensity threshold,
Determine whether that triggering atmosphere lamp controls event according to comparative result.That is, in described intensity of illumination less than preset
During Intensity threshold, atmosphere lamp in central processing unit controls event to be triggered, with determine be currently needed for opening a certain
The atmosphere lamp in region.
Step 120, judge whether the driver actions corresponding to described area-of-interest meets preset rules,
Determine whether that opening and closing corresponds to the atmosphere lamp of described area-of-interest.

Value, and, the frequency of the same area-of-interest of driver's face orientation is less than setpoint frequency threshold value, and,
The continuous non-time of staying of the same area-of-interest of driver's face orientation exceedes setting time threshold.
When the driver actions corresponding to described area-of-interest meets and presets the first rule, determine described sense
Interest region is driver's region-of-interest, is driven by atmosphere lamp in vehicle bus or car and controls corresponding to driving
The atmosphere lamp of member's region-of-interest is opened.
When the driver actions corresponding to described area-of-interest meets and presets Second Rule, determine described sense
Interest region is not driver's region-of-interest, is driven by atmosphere lamp in vehicle bus or car and controls corresponding to non-
The atmosphere lamp of driver's region-of-interest is closed.Wherein, driven by atmosphere lamp in vehicle bus or car
Dynamic control is closed including corresponding to the atmosphere lamp of non-driver region-of-interest: central processing unit detects
The on off state of the atmosphere lamp of non-driver region-of-interest determined by corresponding to.If opening, then in
Central processor issues the out code atmosphere lamp to non-driver region-of-interest by vehicle bus.Set being separated by
After fixing time, the on off state of the atmosphere lamp of this non-driver region-of-interest inquired about by central processing unit, to guarantee
The atmosphere lamp in this region has been switched off, and updates the atmosphere lamp mark of central processing unit.If the atmosphere lamp in this region
For closed mode, central processing unit inquiry atmosphere lamp mark.When atmosphere lamp is designated unlatching, update central authorities
The atmosphere lamp mark of processor.When atmosphere lamp is designated closedown, terminates atmosphere lamp and control event.
The technical scheme of the present embodiment, is determined by the face orientation position of driver, according to described face court
To the area-of-interest determining driver；The fullest according to the driver actions corresponding to described area-of-interest
Foot preset rules, determines the switch of atmosphere lamp corresponding to described area-of-interest.The technical side of the present embodiment
Case solves driver and takes the very inconvenient problem of operation of article during nighttime driving, it is achieved according to
The face orientation position of driver determines that the atmosphere lamp opening which position is to provide illumination, it is simple to driver looks for
To article to be taken, reach operation more intelligent, convenient, and do not disperse the driving demand power of driver
Effect.
