Embodiment 1

[0039] see figure 1 , the present invention provides an anti-glare intelligent tracking protection device based on a dimming film and a steering gear. Sufficient driving vision, while avoiding strong light to the driver. Wherein, the anti-glare intelligent tracking protection device includes a light environment perception module, a signal feedback module, a signal deviation comparison module, a position adjustment module, a light transmittance adjustment module and a control module (core control unit), and may also include a power amplification module. All the modules mentioned above can be installed in the car system. In fact, they can form the anti-glare system of the car together with the light barrier. Of course, these modules can also be used as an independent system.

[0040] There is at least one light environment perception module, that is, at least one module is arranged in the middle of the car light shield, and is used to detect the light intensity at the front sid...

Embodiment 2

[0053] The present invention provides an anti-glare intelligent tracking protection device based on a dimming film and a steering gear. The device is provided with two modes on the basis of Embodiment 1, and these two modes are applied in daytime and night respectively. When the mode is selected, it can be selected manually by the driver or determined by the definition of the clock. In this embodiment, the anti-glare intelligent tracking protection device is in the mode-1 state within a preset time period-. The preset time period can be selected artificially, for example, 6:00-18:00 is selected as daytime, that is, mode 1 is used during this time period, of course, the preset time period can also be directly preset into the device . The anti-glare intelligent tracking protection device is in the mode 2 state within a preset time period 2. The same is true for the second preset time period, which can be selected as 18:00-24:00 of the current day and 0:00-6:00 of the next day,...

Embodiment 3

[0061] This embodiment provides an anti-glare intelligent tracking protection device based on a light-adjustable film and a steering gear. On the basis of Embodiment 1 or Embodiment 2, an opening and closing key module is added to the device. Wherein, the opening and closing key module can be set as a button, which is arranged in the cab of the car, and is used for the driver to open or close the light shield. Of course, in some embodiments, the on / off key module can also be set with different modes of keys (such as the off / on button), press the off / on button to enter the standby mode, press the off / on button again, and the device Not working, it can be used as a conventional light barrier to meet the needs of different drivers. At the same time, the city mode button is set, there will be interference from street lights in the city, press the city mode, change the threshold, and reasonably perform anti-glare .

Abstract

The invention discloses an anti-strong light intelligent tracking protection device and a method thereof based on a dimming film and a steering gear. The device includes a light environment perception module, a signal feedback module, a signal deviation comparison module, a position adjustment module, a light transmittance adjustment module and a control module. The light environment perception module is used to detect the light intensity at the front side of the light baffle to generate a central light intensity signal. The signal feedback module is used to detect the light intensity of the left front and the right front of the light baffle, so as to generate a left light intensity signal and a right light intensity signal correspondingly. The signal deviation comparison module is used to perform differential proportional calculation on the left light intensity signal, the right light intensity signal and the middle light intensity signal respectively. The position adjustment module is used to drive the light baffle to move to adjust the position of the light baffle. The light transmittance adjustment module is used for adjusting the light transmittance of the light baffle. The present invention can also realize the intelligent adjustment of the light-shielding plate while achieving the purpose of anti-glare, and reduces the driving risk caused by the distracted adjustment of the light-shielding plate by the driver.

Description

technical field [0001] The present invention relates to an anti-glare intelligent tracking protection device in the technical field of automobile light blocking, in particular to an anti-glare intelligent tracking protection device based on a dimming film and a steering gear, and also relates to the device's anti-glare intelligent tracking protection device based on a dimming film and a rudder The machine's anti-glare intelligent tracking protection method. Background technique [0002] The existing polymer dispersed liquid crystal dimming film (PDLC) in the market can prevent glare by changing the light transmittance of the front windshield, but its dimming method is single, and can only realize two states of transparent and opaque (fogging). The degree of intelligence is low and the light transmittance cannot be adjusted continuously and gradually. At present, most cars use light barriers to prevent glare. After the light barriers are unfolded, they can basically block th...
