7.3.1.5. System of automatic alignment of headlightsSystem of automatic alignment of headlights (fig. 7.17)
|
|
Fig. 7.17. System of automatic alignment of headlights: 1 – control unit of automatic alignment (main); 2 – control unit of automatic alignment (additional); 3 – forward sensor of automatic alignment; 4 – back sensor of automatic alignment; 5 – executive mechanism of alignment of a headlight (left); 6 – executive mechanism of alignment of a headlight (right); 7 – ABS/TCS HU/CM or DSC HU/CM
|
Optical axes of headlights automatically are established under certain corners for improvement of visibility and prevention of dazzle of drivers of oncoming vehicles at change of speed or loading of the car.
