A kind of bend head light that throws light on automatically
The utility model relates to automobile front.
Automobile lighting system provides illumination for it when vehicle '; Guarantee the safety traffic of vehicle; Be the vitals of car load, along with the continuous innovation of automotive technology, people are also increasingly high to the requirement of Vehicular illumination system; When satisfying safety lighting, requirements such as energy-conserving and environment-protective, intelligence, hommization have been proposed also.
Present automotive headlamp Lighting System can only illuminate the road surface in vehicle dead ahead at Ackermann steer angle, when Vehicular turn; It turns to a side to have lighting blind zone; The driver does not have at night under the situation of street lighting, can't see the condition of road surface of turning side clearly, makes troubles and danger to driving.
The utility model content
The utility model technical matters to be solved is to be implemented in Ackermann steer angle, need just can not turn to the automobile front of side illumination according to the action of bearing circle or pole changer automatically.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of bend head light that throws light on automatically, comprise the head light housing, and be arranged at steering indicating light and lighting headlight in the housing; Described hull outside position is provided with the bend auxiliary lighting lamp; Also be provided with independently handling maneuver sensor, ECU unit and driver element in the described housing, described handling maneuver sensor is connected with the ECU unit, and the ECU unit is connected with the bend auxiliary lighting lamp through driver element.
Described bend auxiliary lighting lamp is provided with three, and its light angle is towards car load side the place ahead.
Described three bend auxiliary lighting lamp light angles are 30 degree, 60 degree and 90 degree with the car load axis angle respectively.
Described handling maneuver sensor adopts the EWTS82 of Panasonic gyro angular velocity sensor.
The advantage of the utility model is to turn to floor light can cover the covering of the fan about turning side 120 degree, guarantees that navigating mate can be known to see condition of road surface clearly, guarantees traffic safety; Each headlight of this auxiliary lighting system is unit independently simultaneously; Do not get in touch with Full Vehicle System, single lamp self-organizing system works alone, and when old vehicle replacing has this function head light, need not reequip and rewiring; Change the i.e. usefulness of lamp, be convenient to promote.
Description of drawings
Face the content of every width of cloth accompanying drawing expression in the utility model specification sheets and the mark among the figure down and make brief description:
Fig. 1 is the bend head light structural representation that throws light on automatically;
Mark among the above-mentioned figure is: 1, housing; 2, lighting headlight; 3, steering indicating light; 4, bend auxiliary lighting lamp
The specific embodiment
Can know referring to Fig. 1; Be provided with lighting headlight 2, steering indicating light 3 and bend auxiliary lighting lamp 4 in the automobile front housing 1; The outside that bend auxiliary lighting lamp 4 is arranged at head light promptly after head light is installed on the car load bend assist illuminator 4 be positioned at car load side the place ahead, be convenient to the illumination of Ackermann steer angle offside the place ahead, bend auxiliary lighting lamp 4 is provided with three and endways arrangement usually; Its light angle is towards car load side the place ahead; Three bend auxiliary lighting lamp 4 light angles are 30 degree, 60 degree and 90 degree with the car load axis angle respectively, and bend auxiliary lighting lamp 4 illumination overlay areas can reach the covering of the fan about 120 ° like this, and guaranteeing does not have the illumination blind area night when driving is turned.Bend auxiliary lighting lamp 4 light sources are not limit, and can be bulb, LED or the indirect light that uses optical material.
Every left and right head light of automobile is provided with independently bend auxiliary lighting lamp 4 control system; This system is made up of handling maneuver sensor, ECU unit and driver element; Each bend auxiliary lighting lamp 4 control system is worked alone, left and right two lamp compartments, and the bearing circle of system and vehicle body is not got in touch; Also do not get in touch with the turn signal swich of car, every head light works alone to accomplish and turns to floor light automatically.Wherein the handling maneuver sensor can adopt the EWTS82 of Panasonic gyro angular velocity sensor; During centnifugal force that the handling maneuver sensor produces during to vehicle movement; Acquired signal is transferred to the ECU unit; Its signal of ECU element analysis; Left side headlight analysis obtains that vehicle begins to turn left or right headlight analysis when obtaining vehicle and beginning to turn right, and ECU sends the unit intensity command and lights through the bend auxiliary lighting lamp 4 of drive unit drives turn side, control system SELF CL bend auxiliary lighting lamp 4 again after vehicle is accomplished handling maneuver.
Control system is specific as follows for the control method of bend auxiliary lighting lamp 4: the ECU unit confirms that at first system self is left lamp or right lamp; Judge according to the signal of handling maneuver sensor whether the Vehicular turn action is consistent with system self; A left side its bend auxiliary lighting lamp 4 of big lamp control system driving is lighted during left-hand rotation; Right big lamp control system drives its bend auxiliary lighting lamp 4 and lights during right-hand rotation, only lights the bend auxiliary lighting lamp 4 of turn side during turning, when angle of turn hour; Light the bend auxiliary lighting lamp 4 that becomes 30 ° of angles with the axletree line, illuminate the side curve ahead; When angle of turn increases, light 2 LEDs of 30 ° and 60 ° positions; When angle of turn continues to increase, light whole 3 LEDs of 30 °, 60 ° and 90 ° positions, obtain maximum and illuminate angle and brightness.The ECU unit starts internal delay time control when lighting bend auxiliary lighting lamp 4, thereby when keeping that action is discontinuous in the turn inside diameter process, the continuing of LED lighted, and time-delay control is until the turn inside diameter release.Under the control of ECU LED light and when extinguishing brightness be gradual change, with guarantee chaufeur night eyes to the applicability of light.
