Vehicle posture transformation detecting device and adaptive vehicle lamp steering system

Abstract

The invention discloses a vehicle posture transformation detecting device. The vehicle posture transformation detecting device comprises a rotating mechanism and a sensor, wherein the rotating mechanism is arranged on a swing arm of a vehicle and moves relative to the swing arm of the vehicle; the sensor is connected with the rotating mechanism, detects the movement track of the rotating mechanism and comprises a rotating shaft, a conductive contact piece, a circuit board and a shell; the conductive contact piece is fixedly arranged at one end of the rotating shaft; a contact of the conductive contact piece is in contact with the circuit board; and the rotating shaft penetrates in the shell, rotates relative to the shell and drives the conductive contact piece to move peripherally along the circuit board. By the rotating mechanism which is arranged on the swing arm of the vehicle and moves relative to the swing arm of the vehicle, the movement track of the swing arm of the vehicle is transmitted, the movement track of the rotating mechanism is detected through the sensor which is connected with the rotating mechanism, so that the movement track of the vehicle is detected simply, quickly and accurately, and posture transformation of the vehicle is implemented. The invention also discloses an adaptive vehicle lamp steering system.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle body attitude transformation detection device and an adaptive vehicle light steering system. Background technique [0002] With the continuous development of automotive electronics technology, safe driving and intelligent driving have put forward higher and higher requirements for the design of automotive electronics and automotive structures. [0003] For example, the current adaptive front-lighting system (AFS: Adaptive Front-lighting system) can timely adjust the rotation direction and pitch angle of the lights, and adjust the irradiation direction of the lights to the driver's desired visual range in time, so that The driver's visual range is improved, and the driving safety is improved, so it has been valued by major automobile manufacturers. In order to adjust the rotation direction and pitch angle of the headlights, it is first necessary to detect the attitu...

Problems solved by technology

The existing method has high requirements on the magnetization intensity of the magnet. At the same time, because the magnet is more sensitive to temperature, when the car is working in a high-temperature or low-temperature environment, the collected body attitude signals often have deviations and large errors.
