Problems solved by technology

[0014] Existing car headlights generally cannot adjust the irradiation direction adaptively. If the vehicle makes a sharp turn at night, since the headlights are always irradiating towards the front of the vehicle, it is easy to cause blind spots in the driver's vision and cause traffic accidents.

Abstract

The invention discloses a Hall-sensing-based adjusting method of an automobile headlamp adjusting system. The automobile headlamp adjusting system comprises a headlamp body, a step motor, a first Hallsensor, a second Hall sensor, a light intensity sensor and a control module; the step motor is used for adjusting horizontal irradiating angle of the headlamp body; the first Hall sensor and the second Hall sensor are arranged on left and right front wheels of an automobile respectively. During operation, the control module controls on or off of the headlamp body according to sensing data of thelight intensity sensor, calculates a horizontal defection angle of the headlamp body according to sensing data of the first and second Hall sensors upon turn-on of the headlamp body and then controlsthe step motor to adjust the horizontal irradiating angle of the headlamp body. The Hall-sensing-based adjusting method of the automobile headlamp adjusting system has the advantages that the design is simple, the method is convenient to use, the irradiating direction of the headlamp is automatically adjusted when an automobile makes turning, visual blind area is eliminated for a driver, and safety is improved.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an adjustment method of an automobile headlight adjustment system based on Hall induction. Background technique [0002] The Hall sensor is a magnetic field sensor made according to the Hall effect. Hall effect is a kind of magnetoelectric effect. This phenomenon was discovered by Hall (A.H.Hall, 1855-1938) in 1879 when he was studying the conductive mechanism of metals. Later, it was found that semiconductors and conductive fluids also have this effect, and the Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing, etc. aspect. The Hall effect is a basic method for studying the properties of semiconductor materials. The Hall coefficient measured by the Hall effect experiment can determine important parameters such as ...
