Description
- 1 ADAPTIVE FRONTLIGHTING SYSTEM FOR MOTOR VEHICLES
TECHNICAL FIELD
5 The present invention relates to an adaptive frontlighting system for motor vehicles, which uses light units of the reflector or projector type, where is solved the composition of the said light units in order to reach optimal and adaptive/variable light distribution of the road surface and 10 its adjacent areas.
At the present time motor vehicles are equipped with symmetrical headlamps, which have the same light sources and basically the same light beams. The headlamps can have a 15 one-chamber light unit that is equipped with two filament bulb or high intensity discharge bulb that is used for two basic functions of the headlamp, for passing and driving beam. The other kind of headlamp is system that consists of two chambers, where each chamber is used for one basic 20 lighting function only. These chambers can be equipped with halogen light sources or can be equipped with discharge bulbs. BACKGROUND ART
The optimization of output illumination flux is solved on a frontlighting system for motor vehicles which consists on both vehicle sides of a scattering light unit and a main light unit.
The advantage of the system is optimization of output light due to homogeneous lateral beam distribution to the side of
- 2 the road surface and its surrounding area.
Main light units are of the bifunctional type that allows their using for passing and driving beam function.
Main light units allow a horizontal movement of lighting beams in angle range +/- amax according to swivel of steering wheel, speed of vehicle and the other sensors and devices dynamically analyzing the road curvature. Main light units 10 are used for optimal illumination of the road in front of the driver. For maximal curvature Rmax of the road in front of the vehicle there is achieved maximal turning movement of lighting beams from main light units in angle range amax, and for minimal curvature kmin in front of the vehicle the 15 movement angle of lighting beams is continuously or discretely decreasing to minimum amin in relation.
a = a (road) 20 where: a (road) - is angle of turning movement of lighting beams from main light units depending on the road shape in front of the driver.
Scattering light units allow a horizontal movement of 25 lighting beams in angle range gmax according to swivel of steering wheel, speed of vehicle and the other sensors and devices analyzing the speed of vehicle and dynamical course of the road curvature. Scattering light units are used for optimal illumination of the areas adjacent to the road. For 30 minimal vehicle speed vmin the maximal turning movement of lighting beams from scattering light units in angle gmax is achieved, and for maximal vehicle speed vmax the turning
- 3 movement angle gmin of lighting beams is continuously or discretely decreasing to minimum.
Simultaneously, the turning movement of lighting beams from 5 scattering light units is proportional to the turning movement of main light units in relation: = (speed) + k* a (road) 10 where: - is total angle of turning movement of lighting beams from scattering light units, (speed) is angle of turning movement of lighting beams from scattering light units depending only on speed of vehicle, a (road) - is angle of turning movement of lighting beams from main light units depending on the road shape in front of driver, 20 k - is a constant determining ratio of turning component from main light unit to total angle of turning movement of lighting beams from scattering light units.
At the same time the vertical adjustment of all or only some 25 of the lighting units is allowed. Dynamical change of vertical inclination of the lighting beams can improve the illumination of the road close in front of the vehicle for minimal vehicle speed vmin, when the inclination angle ymax of lighting beams is maximal, or can improve the distance of 30 visibility/illumination of the road for maximal vehicle speed vmax, when the inclination angle ymin of lighting beams is mlnlmal.
- 4 Main light units are situated closer to the vehicle symmetry axis LVA in opposite with scattering light units or vice versa. Main light units and scattering light units employ halogen light sources or discharge bulbs.

15 DETAILED DESCRIPTION OF THE INVENTION
Optimization of output light beam is solved on an adaptive frontlighting system for motor vehicles according to the present invention shown in Fig. 1, which consists of 20 scattering light units 1, 4 and main light units 2, 3 on both sides of a vehicle. Light units 1, 2, 3, 4 are approximately in the same distance from the longitudinal vehicle symmetry plane LVSP.
25 For the passing beam function are used the scattering light units 1, 4 and the main light units 2, 3 on both sides of the vehicle. Main light units 2, 3 are able to create two lighting functions, passing and driving beam, by a bifunctional mechanism. The bifunctional mechanism uses the 30 shield or light source movement in order to change the lighting function. Simultaneously the horizontal movement of lighting beams from main light units 2, 3 by angle is
- 6 allowed in dependence on the steering wheel rotation, speed of the vehicle and the other devices identifying the curvature of the road in front of the vehicle.
5 For maximal road curvature Rmax in front of the vehicle the maximal movement of lighting beams from main light units 2, 3 in angle omax is achieved, and for minimal road curvature Rmin in front of vehicle the movement angle amin of the main light beams is continuously or discretely decreasing to 10 minimum in the relation a = a (road) where (road) is the movement angle of light beams from main 15 light units 2, 3 in dependence on road shape in front of the driver. Horizontal turning movement of lighting beams is possible also with scattering light units 1, 4 in range of angle gmax 20 in dependence on the speed of the vehicle, steering wheel rotation, and the other sensors and devices describing speed of the vehicle and dynamic course of the curvature of the road. Scattering light units 1, 4 are used for optimal illumination of adjacent parts of the road. For minimal 25 vehicle speed vmin the maximal turning movement of lighting beams from scattering light units in angle gmax is achieved, and for maximal vehicle speed vmax the movement angle fmin of lighting beams is continuously or discretely decreasing to minimum. Simultaneously, the turning movement of lighting beams from scattering light units 1, 4 is proportional to the turning
- 7 movement of main light units 2, 3 in relation: = (speed) + k* a (road) 5 where: - is the total angle of turning movement of lighting beams from scattering light units 1, 4 (speed) - is the angle of turning movement of lighting beams from scattering light units 1, 4 depending only on 10 speed of vehicle, a (road) - is the angle of turning movement of lighting beams from main light units 2, 3 depending on the road shape in front of driver, k - is a constant determining ratio of turning component from main light unit 2, 3 to total angle of turning movement of lighting beam from scattering light units 1, 4.
20 Referring to Fig. 2, a range of horizontal movements of lighting beams from light units 1, 2 is shown, and referring to Fig. 3 the horizontal turning movement of lighting beam from scattering light unit 1 by angle for a straight road in front of the vehicle and for constant speed of vehicle v = 25 const is shown.
In Fig. 4 and Fig. 5 are shown dynamic changes of rotated lighting beams from scattering light units by angle +/-k x a, and lighting beam from main light units by angle a in the 30 left and right curves.
In Fig. 6 and Fig. 7 are shown dynamic changes of rotated
- 8 lighting beam from scattering light unit by angle gmax, and lighting beam from main light unit by angle omax in the left and right curves.
5 Each of the light units 1, 2, 3, 4, or possibly only some of them, allow dynamic change of vertical inclination of lighting beams in angle range y in dependence on speed of vehicle v.
10 For minimal speed of the vehicle, for example in a town, it is possible to use vertical inclination of lighting beams from light units 1, 2, 3, 4 by angle ymax in order to increase illumination of the road in the proximity of the vehicle. On the contrary, for maximal speed of vehicle, for 15 example on highway, it is possible by means of vertical inclination of lighting beams from light units 1, 2, 3, 4 by angle ymin to increase illumination of the road far in front of the vehicle.
20 For driving beam function the main light units 2, 3 are used.
Scattering light units 1, 4 with their low beam pattern may be used as a contributor to the main light units 2, 3 which generate the true driving beam. Horizontal movement of lighting beams takes place only at main light units 2, 3.
25 Lighting beams from scattering light units 1, 4 are adjusted in the angle fmin.
Main light units 2, 3 are situated closer to the longitudinal vehicle axis LVA and scattering light units 1, 4 are further 30 from the longitudinal vehicle axis LVA or vice versa.
In case of failure the system vertically aims the light unit
9 - where the failure was diagnosed. If the failure is diagnosed on an actuator which is used for vertical/horizontal movement the system turns off the light source which could have an impact on parasitic on-coming drivers glaring.
