Embodiment approach

[0019] figure 1 Shown is the structural diagram of the automobile intelligent headlight system according to the present invention. Including: sensors to measure the longitudinal and lateral acceleration of the car, a central control unit with a built-in mathematical model for corner calculation and a headlight drive control module. The output end of the acceleration sensor is connected with the input end of the central control unit, and the output end of the central control unit is connected with the drive control module.

[0020] Among them, the acceleration sensor is used to measure the acceleration change of the vehicle in the longitudinal direction and the measurement, and the measured acceleration signal is used to calculate the horizontal rotation angle of the headlight. In the central control unit, the control algorithm of the headlight angle imitating the driver's preview behavior is written. The control algorithm combines the current motion state of the car to make...

Abstract

The invention relates to a vehicle head lamp system simulating preview action of a driver, which adopts the technical scheme that longitudinal and lateral acceleration signals of a vehicle are obtained by a sensor; a curve integral algorithm is established by combining the motion feature parameter to predict a future travelling track of the vehicle; the concerned road position of the driver i.e. a region needing lighting is computed to obtain a required rotation angle of a headlamp in horizontal direction; and a drive motor receives turning angle signals and controls the rotation of the head lamp in the horizontal direction. The system can reasonably control the light region of the headlamp, ensures sufficient lighting in the concerned main road region of the driver during night drive, provides sufficient response time for the driver treating emergency situation ahead, and reduces the tensity of the driver, thereby having important significance for safety of night drive.

Description

Technical field: [0001] The invention relates to an automobile intelligent headlight system, in particular to an automobile headlight system which calculates the corresponding horizontal rotation angle of the headlight by estimating the expected position of the vehicle through the current motion state of the automobile, that is, the preview area of ​​the driver. Background technique: [0002] The lighting system of a car plays a vital role in traffic safety. When the car is driving at night, the main irradiation direction of traditional headlights is fixed relative to the car body, and will not change with changes in road or weather conditions. When passing through country roads with many forks, bends, crossroads and other road conditions, the driver cannot detect potential dangers ahead of the road in time, which can easily lead to traffic accidents. In order to improve the safety of driving at night, the automobile headlight system is constantly developing. So far, it ha...
