7.3.1.5. System of automatic alignment of headlights

System 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.

Fig. 7.18. The scheme of work of system of automatic alignment of headlights at change of loading of the car: 1 – zeroing; 2 – increase in loading; 3 – control unit of automatic alignment (main); 4 – control unit of automatic alignment (additional); 5 – forward sensor of automatic alignment; 6 – back sensor of automatic alignment; 7 – executive mechanism of alignment of a headlight (left); 8 – executive mechanism of alignment of a headlight (right); 9 – ABS/TCS HU/CM or DSC HU/CM; 10 – a difference between two signals of tension; 11 – spatial position of the car; 12 – size of adjustment of an optical axis; 13 – optical axis; 14 – reference mark; 15 – highly; 16 – low


Fig. 7.19. The scheme of work of system of automatic alignment of headlights at the movement of the car: 1 – zeroing; 2 – acceleration; 3 – delay; 4 – control unit of automatic alignment (main); 5 – control unit of automatic alignment (additional); 6 – forward sensor of automatic alignment; 7 – back sensor of automatic alignment; 8 – executive mechanism of alignment of a headlight (left); 9 – executive mechanism of alignment of a headlight (right); 10 – ABS/TCS HU/CM or DSC HU/CM; 11 – a difference between two signals of tension; 12 – spatial position of the car; 13 – calculation of an angle of acceleration; 14 – change of speed of the car; 15 – size of adjustment of an optical axis; 16 – optical axis; 17 – reference mark; 18 – highly; 19 – low; 20 – car speed; 21 – time
