In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all should belong to the scope of the application's protection.
Embodiment mono-:
The application discloses a kind of lights of vehicle control system, be provided with the pitch regulation axle (not shown) of the pitching irradiating angle for regulating head lamp on the head lamp of vehicle, the structural representation that Fig. 1 is the disclosed lights of vehicle pitching of the embodiment of the present application irradiating angle control system.
As shown in Figure 1, in figure, 10 is head lamp, and this system comprises: body inclination angle detecting unit 11, pitching irradiating angle calculating unit 12, pitching motor actuator 13 and pitch regulation motor 14.
Body inclination angle detecting unit 11 is for detection of the body inclination angle.
In the embodiment of the present application, the distance by detecting vehicle body front distance ground and body tail are realized the detection to the body inclination angle apart from the distance on ground.When body forward structure equals body tail apart from the height on ground apart from the height on ground, take the now plane at vehicle body place is reference plane, and when the height of body forward structure during higher than the height of body tail, the angle of inclination of setting vehicle body on the occasion of, when the height of body forward structure, during lower than the height of body tail, setting the body inclination angle is negative value.
When the road surface situation comparatively complicated (such as: hollow appears in upward slope, descending or road surface), vehicle load changes or during the situation such as vehicle generation acceleration-deceleration, generally all can cause body inclination, and then make the body inclination angle occur changing.
For example: the flex point when vehicle from straight road traveling to ramp, the summit in ramp or while travelling the ramp changed to some extent in the gradient, corresponding variation can occur along with the variation on road surface the body inclination angle; When handling goods or passenger getting on/off, also can change due to the load of vehicle each several part and cause the body inclination angle to change; In addition, when the situation of vehicle generation acceleration or deceleration, also can cause that the vehicle body luffing angle changes.
Pitching irradiating angle calculating unit 12, for detecting the pitching irradiating angle of the body inclination angle calculation head lamp obtained according to body inclination angle detecting unit 11.
When changing, the body inclination angle can affect the radiation situation of head lamp 10, in order to eliminate this bad impact, will calculate according to the body inclination angle pitching irradiating angle of head lamp 10, and body inclination angle and pitching irradiating angle are one to one.When the body inclination angle be on the occasion of the time, head lamp 10 should be regulated downwards, now the pitching irradiating angle is negative value; In like manner, when the body inclination angle is negative value, the pitching irradiating angle be on the occasion of.The absolute value of body inclination angle is larger, and the absolute value of pitching irradiating angle is larger.The pitching irradiating angle can be directly proportional to the body inclination angle, or regulates the pitching irradiating angle according to the body inclination angle with other curve modes.
