Description

A kind of automobile LED head lamp bend control system

Technical field

The utility model relates to a kind of automobile LED head lamp bend control system.

Background technology

Existing head lamp bend control system; Adopt and gather the steering wheel angle data, utilize the wheelbase of car and the corner of wheel to calculate, it is big to draw head lamp angle of turn error; How providing a kind of angle precision high, energy-conservation head lamp bend control system, is the technical barrier of this area.

Summary of the invention

The technical matters that the utility model will solve provides a kind of when automobile turning, the automobile LED head lamp bend control system of ability automatically regulating upper beam irradiation angle.

In order to solve the problems of the technologies described above; The utility model provides a kind of automobile LED head lamp bend control system, and it comprises: the angular velocity sensor of collection vehicle angle of turn data, the acceleration pick-up of collection vehicle angular movement speed data, calculate ARM main control module, the LED head lamp of the running orbit of 0-2 vehicle after second, the irradiating angle and the corresponding to head lamp control module of said running orbit of the said LED head lamp of control according to said turn inside diameter angle-data and vehicle movement speed data; Said angular velocity sensor links to each other with said ARM main control module with acceleration pick-up, and said ARM main control module links to each other with said head lamp control module.

Said head lamp control module comprises: the driving circuit that links to each other with said ARM main control module, the stepping motor that links to each other with said driving circuit, the turntable that is in transmission connection with this stepping motor; Said LED head lamp is located on this turntable.

For the turning track that calculates vehicle that can be efficient, energy-conservation, said ARM main control module comprises: A/D convertor circuit, input port, ARM process chip, output control mouth, said arm processor chip adopts sc2410 or S3SC2440.

For cost-cutting, said angular velocity sensor is the ENC-03MB of field, village company, and said acceleration pick-up is the MMA7660 of Freescale company.

In order to give the better reaction time of chaufeur, after calculating said data, said ARM main control module draws the running orbit of vehicle after 2 seconds.

The technique scheme of the utility model is compared prior art and had the following advantages: (1) the utility model is according to the turn inside diameter data of said acceleration pick-up and angular velocity sensor collection, and the data of collection accurately and reliably; (2) utilize ARM that said turn inside diameter data are calculated after, can anticipation go out the running orbit of following 2 seconds vehicles, in time adjust the irradiating angle of head lamp, make chaufeur avoid the potential danger on the road; (3) adopt the LED head lamp, on energy-conservation basis, improve irradiation distance.

Description of drawings

For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein

Fig. 1 is the structural diagrams intention of said automobile LED head lamp bend control system;

Fig. 2 is said ARM main control module scheme drawing.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated

Like Fig. 1, a kind of automobile LED head lamp bend control system comprises: angular velocity sensor 1, acceleration pick-up 2, ARM main control module 3, head lamp control module 4, LED head lamp 5; Said angular velocity sensor 1 transfers to said ARM main control module 3 with the turn inside diameter data process that acceleration pick-up 2 collects; Draw the running orbit of 0-2 vehicle after second after 3 pairs of said data of said ARM main control module are calculated, and be consistent through the irradiating angle and the said running orbit of the said LED head lamp 5 of head lamp control module 4 adjustment.

Said head lamp control module 4 comprises: the driving circuit that links to each other with said ARM main control module 3, the stepping motor that links to each other with said driving circuit, the turntable that is in transmission connection with this stepping motor; Said LED head lamp 5 is located on this turntable.

The turn inside diameter angle-data that said angular velocity sensor 1 and acceleration pick-up 2 collect respectively and angular movement speed data calculate the vehicle movement track of 0-2 second of vehicle through said ARM main control module 3 combination Newtonian mechanicss and Triangle Formula principle.

The adusk speed of response of chaufeur is 2 seconds, but in time reacts in order to be suitable in the continuous little turning process of chaufeur head lamp, then need calculate the vehicle movement track that is lower than in 2 seconds.Like Fig. 2, said ARM main control module 3 comprises: A/D convertor circuit, input port, ARM process chip, output control mouth, said arm processor chip adopts sc2410 or S3SC2440.

Said angular velocity sensor 1 is the ENC-03MB of field, village company, and said acceleration pick-up 2 is the MMA7660 of Freescale company.

Stay the enough reaction time to chaufeur, draw the running orbit of vehicle after 2 seconds after 3 pairs of said data of said ARM main control module are calculated.

Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
