Abstract
The invention relates to a car lamp adjusting device, in particular to a motor vehicle lamp following adjusting device and an adjusting method. The motor vehicle lamp following adjusting device comprises a laser generator, a photoelectric receiver, a signal processor and an executing mechanism, wherein the laser generator is arranged on a motor vehicle and is used for emitting a laser signal; the photoelectric receiver is used for receiving the laser signal reflected by a pavement and transmitting a real-time signal to the signal processor; the signal processor analyzes and processes the received real-time signal and transmits a control signal to the executing mechanism; and the executing mechanism is used for receiving the control signal sent by the signal processor and adjusting a pitching angle of a car lamp. The motor vehicle lamp following adjusting device disclosed by the invention has the advantages that the pitching angle of the car lamp can be adjusted based on the road condition in the driving direction when a motor vehicle runs while the car lamp is required for illumination, so that the disadvantageous effects on the motor vehicle due to poor road condition can be avoided; and the effect on lighting of the pavement can be improved.
Description
Technical field
The present invention relates to a kind of car light setting device, relate in particular to a kind of Vehicular lamp servo-actuated setting device and method of adjustment.
Background technology
According to disclosed technology, illumination now is according to the sensor measurement automotive pitch angle on the car with the servo-actuated setting device of car light, all is to be object of reference with the horizontal surface.But automobile is to go on the road surface, and the road surface might not be parallel with horizontal surface.Therefore as long as put down on the road surface, no matter with horizontal surface much inclination angles are arranged, sensor records much pitch angle values in other words, and light all needn't be adjusted, and promptly to adjust angle be not single valued relation for the angle value that records of sensor and light.
In addition, what sensor was surveyed is ground-surface fluctuating under the wheel, is the road surface at least ten meters in car the place ahead and light need throw light on and the people hopes to observe, and both obviously are differentiated, this under some road conditions, the follow-up illumination effect very severe that will become.Car light can not in time in time be adjusted according to the fluctuating of road conditions.
Summary of the invention
In order to solve the problems of the technologies described above the present invention a kind of car light servo-actuated setting device and method of adjustment are provided, purpose is in time to adjust according to the car road conditions contrasts bright lamp that goes.
For reaching above-mentioned purpose car light servo-actuated of the present invention setting device, be made up of following structure: laser generator is located on the self-propelled vehicle and sends laser signal; Photelectric receiver receives the laser signal through road reflection, and live signal is delivered to signal processor; Signal processor carries out analyzing and processing to the live signal that receives, and transmits control signal to actuating unit; Actuating unit receives the control signal that signal processor sends, and the luffing angle of car light is adjusted.
The photosensitive surface of photelectric receiver has the unit of an independent output, and actuating unit is a mechanical drive.
Laser generator and photelectric receiver are respectively two, and a laser generator and a photelectric receiver are one group, have two groups, and two groups of diverse locations at self-propelled vehicle carry out work simultaneously.
Laser generator the place ahead is provided with cylindrical mirror, and the place ahead of photelectric receiver is provided with object lens.The unit that the photosensitive surface of photelectric receiver is independently exported by multichannel is formed.
The method of adjustment of car light servo-actuated setting device; Laser generator sends laser; Photelectric receiver receives the signal after the reflection of road surface, and signal is delivered to signal processor, and signal processor compares live signal and setting value; Transmit control signal according to result relatively to actuating unit, actuating unit is adjusted the pitch angle of car light according to the control signal that transmits.
When live signal was range signal, when the distance that records in real time during greater than setting value, car light was adjusted downwards; When the distance that records in real time equaled greater than setting value, car light was not adjusted; When the distance that records in real time less than greater than setting value the time, car light adjusts upward.
When live signal is the light intensity weak signal
,When the light intensity weak signal that records in real time during greater than setting value, car light adjusts upward; When the light intensity weak signal that records in real time equaled setting value, car light was not adjusted; When the light intensity weak signal that records in real time during less than setting value, car light is adjusted downwards.
Advantageous effect of the present invention: need self-propelled vehicle that car light throws light under steam, can adjust the pitch angle of car light, avoided because the bad harmful effect that self-propelled vehicle is produced of road conditions according to the road conditions of working direction.Improve the illuminating effect of road pavement.
