A car body attitude change detection device and an adaptive car light steering system

Abstract

The invention discloses a vehicle body attitude change detection device, comprising: a rotating mechanism installed on a vehicle body swing arm and moving relative to the vehicle body swing arm; a sensor connected with the rotating mechanism and detecting the movement track of the rotating mechanism ; Wherein, the sensor includes: a rotating shaft, a conductive contact piece, a circuit board and a housing; the conductive contact piece is fixedly installed at one end of the rotating shaft; the contact of the conductive contact piece is in contact with the circuit board; the rotating shaft passes through the housing, and is relatively Rotating, the rotating shaft drives the conductive contact piece to make a circular motion along the circuit board. By being installed on the swing arm of the car body, the movement track of the swing arm of the car body can be transmitted relative to the rotating mechanism of the swing arm of the car body, and at the same time, the movement track of the turning mechanism is detected by the sensor connected with the turning mechanism, so that it is simple, fast and accurate The trajectory of the car body is detected, and the attitude transformation of the car body is obtained. The invention also discloses an adaptive vehicle light 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.
