Sun shield three-dimensional control method considering seat position based on EPS, TBOX and camera

Abstract

The invention discloses a sun shield three-dimensional control method considering a seat position based on EPS, TBOX and a camera. The sun shield three-dimensional control method considering the seatposition based on the EPS, the TBOX and the camera comprises the following specific steps that a fisheye camera is started, sunlight irradiation intensity is judged by detecting brightness of a picture, and an intensity signal is sent to the control unit; the control unit receives the signal and judges whether the sunlight irradiation intensity reaches an opening standard of the sun shield or not;and the signal is output according to a demand. Existing equipment of a vehicle is borrowed, hardware equipment is not additionally arranged, the light intensity, direction and angle of sun irradiation can be accurately judged only through software, the body type of a driver, the position of the seat and the inclination angle of a backrest of the seat are considered, accuracy of obtained controlinformation is high, the sun shield can rotate in a three-dimensional mode, and a good effect on lateral irradiation is achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a three-dimensional control method of a sun visor considering seat positions based on EPS, TBOX and cameras. Background technique [0002] With the advancement of science and technology and the development of society, the number of car ownership continues to increase, and cars have become a common means of transportation for people to travel. Now cars are becoming more and more intelligent and networked. [0003] At present, car sun visors are manually adjusted. Some manufacturers have introduced smart car sun visors, which collect information through light sensors and adjust the sun visors. The more expensive ones are to adjust the transmittance of the LCD screen. The price is high and there are few applications. There are some conceptual LCD screen products in the existing technology, which have not yet been put into use on a large scale. Other motor-controlled automatic su...

Problems solved by technology

[0003] At present, the car sunshade is adjusted manually. Some manufacturers have introduced smart sun visors for cars, which collect information through light sensors and adjust the sun visor. The more expensive ones are to adjust the transmittance of the LCD screen. The price is high and there are few applications.

There are some conceptual LCD screen products in the existing technology, which have not yet been put into use on a large scale. Other motor-controlled automatic sunshade products can only rotate up and down, and additional light sensors need to be installed. The effect on lateral sunlight is poor, and the seat is not considered. Position information, sun exposure from the side and front, and feedback control, the accuracy of controlling the movement of the sun visor is low, and the position of the light sensor is also easily affected, and the maturity is low and the price is high
