Description

Mobile vehicle assistance system and vehicle electronic rearview mirror

This creation is related to the mobile vehicle assist system; in particular, it refers to a display system that can show changes in color and transparency.

With the high-frequency commercial activities and the rapid expansion of transportation and logistics, people are becoming more dependent on mobile vehicles such as automobiles and motorcycles. At the same time, drivers are paying more and more attention to the protection of their lives and property while driving. In addition to the performance of the mobile vehicle and the comfort of the ride, consideration will also be given to whether the mobile vehicle to be purchased provides sufficient safety protection or auxiliary devices. In this trend, in order to increase the safety of vehicles, car manufacturers or vehicle equipment design manufacturers have developed various driving safety protection devices or auxiliary devices, such as rear-view mirrors, driving recorders, and objects that can instantly display driving dead-end areas. Surrounding images or global positioning systems that record driving paths at any time.

In addition, with the popularization of digital cameras in daily life and the rapid development of computer vision in recent years, it has been applied to driver assistance systems. It is hoped that the incidence of traffic accidents will be reduced by the application of artificial intelligence.

Taking traditional rear-view mirrors as an example, when changing lanes or turning, drivers mostly use it to observe and determine the presence of objects outside the car. However, most rear-view mirrors have limitations and deficiencies in the use of certain driving situations. For example, when driving at night, in a dark environment, the eyes of the driver are like the shutter of a camera, and the pupils are open to provide optical signals with more optic nerves. In this state, the driver's eyes will have an extremely sensitive response to sudden bright light. Generally, the car's front lights reflected from passing cars or subsequent cars will cause the driver to experience dizziness, which will cause the driver's visual ability to decrease rapidly in an instant, thus increasing the driver's obstacles to the front. Becomes visible when the response time.

With this, when an applied voltage or current is applied (enabling), the optical properties of the electro-optic dielectric layer in the visible light wavelength range (such as light transmittance, reflectance, or absorbance) can produce stable reversible changes, thereby Can show changes in color and transparency.

When the external light intensity is too strong and affects the driver's eye sight, the light beam reaches the electro-optical dielectric layer of the electronic rear-view mirror of the vehicle, and the external light will be absorbed by the electro-optic dielectric layer to become matte, so that the electronic rear-view mirror of the vehicle is switched to antiglare mode.

FIG. 3B is a second optical embodiment in order from left to right. Spherical aberration, astigmatism, and optical distortion curves of the optical imaging system 20 of FIG. As can be seen from FIG. 3A, the optical imaging system 20 includes the first lens 210, the second lens 220, the third lens 230, the aperture 200, the fourth lens 240, the fifth lens 250, and the sixth lens in this order from the object side to the image side. 260 and a seventh lens 270, an infrared filter 280, an imaging surface 290, and an image sensing element 292.

The first lens 210 has a negative refractive power and is made of glass. Its object side surface 212 is convex, its image side 214 is concave, and both are spherical.

The second lens 220 has a negative refractive power and is made of glass. Its object side surface 222 is a concave surface, and its image side surface 224 is a convex surface, and they are all spherical surfaces.

The third lens 230 has a positive refractive power and is made of glass. The object side surface 232 is a convex surface, and the image side surface 234 is a convex surface, and they are all spherical surfaces.

The fourth lens 240 has a positive refractive power and is made of glass. The object side surface 242 is a convex surface, and the image side surface 244 is a convex surface, and they are all spherical surfaces.

The fifth lens 250 has a positive refractive power and is made of glass. The object side surface 252 is a convex surface, and the image side surface 254 is a convex surface, and they are all aspheric surfaces.

The sixth lens 260 has a negative refractive power and is made of glass. The object side surface 262 is a concave surface, and the image side surface 264 is a concave surface. Accordingly, the angle of incidence of each field of view on the sixth lens 260 can be effectively adjusted to improve aberrations.

The seventh lens 270 has a negative refractive power and is made of glass. Its object side surface 272 is convex and its image side 274 is convex. Thereby, it is advantageous to shorten the back focal length to maintain miniaturization. In addition, it can effectively suppress the incident angle of the off-axis field of view, and further correct the aberration of the off-axis field of view.

The infrared filter 280 is made of glass and is disposed between the seventh lens 270 and the imaging surface 290 without affecting the focal length of the optical imaging system 20.
