Modular autonomous compliance steering device and steering method for automobile headlamp

Abstract

The invention discloses a modular autonomous compliance steering device and a steering method for an automobile headlamp. The device comprises a rotary bracket, a lens assembly and a driving platform, wherein the lens assembly is rotationally arranged on the rotary bracket; and the driving platform is arranged on the rotary bracket and can drive the lens assembly to rotate on the rotary bracket. The method comprises the following steps: (1), a gyroscope and an acceleration sensor send sensed information to a microprocessor; (2), the microprocessor receives the sensed information sent by the gyroscope and the acceleration sensor respectively, calculates out a signal of an angle that the lens assembly is required to be rotated, converts the signal of the angle that the lens assembly is required to be rotated to a control signal and sends the control signal to a stepping motor driver; and (3), the stepping motor driver controls a stepping motor to work according to the control signal sent by the microprocessor. The device is simple in structure, adopts an integrated structure wholly, and very convenient to mount, so that the improvement difficulty and improvement cost of the headlamp are greatly reduced.

Description

technical field [0001] The invention relates to a follow-up steering device for automobile headlights, in particular to a modular autonomous headlight follow-up steering device and a steering method. Background technique [0002] High-intensity discharge vehicle headlights (Xenon lamps) are increasingly becoming the technology of choice for vehicle manufacturers worldwide. Vehicles with "follow-up steering technology" (AFS technology) of headlights can adjust the angle of horizontal projection of headlights according to changes in vehicle steering. Such beams can provide the best and safest road lighting ahead, significantly Improves road visibility for drivers when cornering. [0003] Typical "follow-up steering technology" includes: the vehicle's data network provides real-time sensor data about steering angle and wheel speed. Based on this information, the headlight system can adapt the distribution of light to the steering angle of the vehicle for oncoming traffic Onco...

AI Technical Summary

Problems solved by technology

At present, some high-configuration vehicles have been equipped with a headlight follow-up steering system, but this follow-up steering system is composed of multiple individual components, and these components are installed on various parts of the car, such as in Install sensors and related wiring harnesses on the chassis, and install controllers and other components on the car's central control. The above-mentioned components cannot be installed in one piece, which is very inconvenient and expensive to install.
