Description

Automobile rearview mirror with adjustable reverse trajectory line

Technical field

The utility model relates to a reversing rear view device, and more particularly to an automobile rearview mirror with an adjustable reverse trajectory line. Background technique

At present, the reverse trajectory line on the rear view mirror display can be displayed, mainly in the following four types:

1. Real-time integrated dynamic reversing trajectory

This reversing trajectory uses a high-speed CPU to perform DSP calculations to form a reversing trajectory screen with a left reverse trajectory and a right reverse trajectory. The CPU receives the rotation information of the steering wheel of the car, and the output swings as the steering wheel rotates. The dynamic reversing trajectory screen, this dynamic reversing trajectory screen is displayed on the reversing display, superimposed with the image of the reversing camera to give the real reversing information behind the owner's car. This is a perfect solution, but the cost is too high and the circuit is complicated. At the same time, because the steering wheel rotation information transmission mode of different models is different, it is more suitable for the batch installation of a vehicle model for a vehicle. Individual manufacturers have implanted this solution into the steering wheel communication protocol of many models. As a result, the circuit is more complicated and costly, resulting in high price and difficult to meet the market's economical requirements. This circuit can be used in the reversing camera to load the reverse trajectory in the camera. It can also be a function box connected in series between the reversing camera and the reversing display. In this box, the loading of the reversing trajectory is realized. Or it can be in the reversing display to realize the loading of the reverse trajectory.

2, the left and right integration can be arbitrarily adjusted static reversing trajectory This reversing trajectory does not change with the steering wheel of the car. The part of the reversing trajectory is composed of a high-cost CPU and a DSP, and outputs a reversing trajectory image in which a left reverse trajectory and a right reverse trajectory are integrated. This circuit can be used in the reversing camera to load the reverse trajectory in the camera. It can also be a function box connected in series between the reversing camera and the reversing display. In this box, the loading of the reversing trajectory is realized. Or it can be in the reversing display to realize the loading of the reverse trajectory. This kind of scheme has high cost, complicated circuit and high failure rate, which is difficult to meet the market's economical requirements.

3, left and right integration non-real static reverse trajectory line

This reversing trajectory is superimposed on the reversing display system, and some are superimposed on the reversing camera system. In short, it is a reverse trajectory that cannot be adjusted. This reversing trajectory is completely the manufacturer's guess of the car's reverse trajectory position, one-time production is completed, the customer can not make any adjustments. The possibility of the reverse trajectory displayed on the screen and the true overlap of the reverse trajectory is very small. That is to say, the information of the reverse trajectory obtained by the driver is an unreal reverse trajectory line, which is likely to cause a driver's misjudgment and cause a car accident.

4. The real static reversing trajectory of the left and right integration limited range adjustment

According to the scheme described in the above 3, during production, the real reversing trajectory of various models is preset to the product, and the different reversing trajectory line numbers are adjusted by the remote controller or buttons to realize various reversing trajectories in the reversing Switch on the screen. This kind of scheme, because the number of trajectory lines that can be stored is limited, it can only adapt to a limited number of models, and if the customer replaces the reversing camera or the installation position, several reversing trajectories have been built, all of which cannot meet the new one. Actual reversing trajectory. This solution, the upper and lower left and right adjustment of the whole left and right integrated reversing trajectory can also be realized by remote control or button, as close as possible to the real reversing trajectory; however, There is still a difference with the actual trajectory line, because the number of reversing trajectory images of the left and right integration is limited, while the left and reverse reversing lines, the shape and position of the two reversing trajectories are changing, both of which are The result of combining the changing reversing trajectories is infinite. Therefore, this solution cannot provide customers with a real, adjustable, static reversing trajectory.

In the first and second schemes described above, in the system FLASH memory, there is no fixed static reverse trajectory picture, and the displayed reverse trajectory is displayed according to the result of the CPU operation, that is, the final reverse trajectory is the CPU. The embodiment of the result of the operation. This method can achieve any adjustment of the reverse trajectory, but the cost is high, the system is complicated, and it is difficult to be accepted by the public. The third and fourth schemes are pre-stored in the FLASH memory of the system, in the form of static pictures, into the picture of the reverse trajectory, by capturing the picture of the reverse track, and superimposing on the reverse video to realize the function of the reverse track display. . This method is relatively low in cost, but the third scheme gives the driver an unreal reverse trajectory, which is easy to cause accidents and disputes. The fourth scheme can only meet the customer's true adjustment in a certain range. The demand for static reversing trajectory can't really satisfy a product. By adjusting the trajectory, it can meet the requirements of all models. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a rearview mirror with an adjustable reverse trajectory line that is low in cost, simple in operation, stable and reliable.

In the FLASH memory, each of the various types is stored in the form of a static picture. The angle of the left reversing trajectory static picture and the right reversing trajectory static picture, first adjust the static picture of the reversing trajectory on one side of the left and right, so that it is displayed on the reversing display, replace the different pictures, find the angle of the reverse trajectory with the reality Almost parallel a static picture of the reversing trajectory, then adjust its position up and down, left and right, let it follow the realistic reversing trajectory The lines overlap, so that the reverse trajectory on one side is adjusted, and the other side is adjusted, and finally the left and right are combined and displayed on the screen to realize a real display of the reverse trajectory. The utility model adopts the method of picking up static pictures of different reversing trajectory lines, and realizes the dynamic adjustment of the angle rotation of the reverse trajectory; by using the methods of respectively adjusting the left and right reversing trajectory lines, two sets of limited static picture pictures are realized. , combined with a lot of display effects of the reverse track. The left and right reversing lines and the right reversing line can be moved up and down, respectively, to solve the trouble caused by the asymmetry of the left and right reversing trajectories in many cases; the utility model innovatively superimposes two transparent pictures, and adjusts the trajectory lines Divided into the left half adjustment, the right half adjustment, the left half, the right half has a variety of trajectory lines, while the left and right sides can be adjusted up and down and left and right, solving the traditional reverse trajectory adjustment method cost is too high, can not realistically simulate reversing The problem of the trajectory line, and the cost of the patent solution is low, the system is stable and reliable, and the operation is simple.
