Abstract
Description
Technical Field
[0001] This invention relates to the automotive field, and more specifically, to a reversing image self-recovery system and method. Background Technology
[0002] With the widespread adoption of intelligent connected vehicles, reversing camera systems have become an essential feature for drivers. Reversing camera assistance systems capture video footage using a camera installed at the rear of the vehicle and display the scene behind the vehicle. When the driver reverses, the system automatically triggers, providing the driver with an image of the rear of the vehicle. This is a frequently used assistance system.
[0003] However, existing reversing camera systems often experience display failures due to non-persistent faults such as electromagnetic compatibility interference, system mismatch, and software errors. If these failures cannot be quickly resolved, they can severely impact the user experience. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a reversing image self-recovery system and method, which solves the technical defects in existing technologies where the reversing image continuously fails due to non-persistent failure of the reversing image system's software and hardware, thereby improving the user experience and reducing after-sales service costs.
[0005] To achieve the above-mentioned technical effects, the present invention adopts the following technical solution:

[0009] The signal transmitting module is used to transmit the reverse gear signal;
[0010] The control module controls the camera module according to a preset strategy to achieve self-recovery of the reversing image;
[0011] The preset strategy is to record the number of times the reversing image is reset through the control module. When an abnormality is detected in the video signal, the control module resets the detection decoding module and the camera module according to the number of resets.
[0012] Preferably, in the preset strategy, the control module records the number of times the reversing image is reset within a preset time range. When an abnormality is detected in the video signal, the control module resets the detection decoding module and the camera module according to the number of resets.
[0013] Preferably, in the preset strategy, when the control module determines whether to reset the detection decoding module or the camera module based on the number of resets, it first determines whether the decoding chip is abnormal. If it is abnormal, the detection decoding module is reset; if it is not abnormal, the camera module is reset.
[0014] Preferably, the control module supplies power to the camera module, and the control module resets the camera module by disconnecting the power supply.
[0015] Preferably, the preset strategy is to analyze the duration of the abnormality through the control module, and the control module resets the detection decoding module and the camera module according to the number of resets and the duration of the abnormality.
[0016] According to another aspect of the present invention, a method for self-recovery of reversing images is provided, characterized by comprising the following steps:
[0017] The power module supplies power to the control module, and the camera module, which includes a camera, captures external video information.
[0018] The reverse gear signal is transmitted using the signal transmitting module.
[0019] The control module controls the camera module according to a preset strategy to achieve self-recovery of the reversing image;
[0020] The preset strategy is to record the number of times the reversing image is reset through the control module. When an abnormality is detected in the video signal, the control module resets the detection decoding module and the camera module according to the number of resets.
[0021] Preferably, in the preset strategy, the control module records the number of times the reversing image is reset within a preset time range. When an abnormality is detected in the video signal, the control module resets the detection decoding module and the camera module according to the number of resets.
[0022] Preferably, in the preset strategy, when the control module determines whether to reset the detection decoding module and the camera module based on the number of resets, it first determines whether the decoding chip is abnormal. If it is abnormal, the detection decoding module is reset; if it is not abnormal, the camera module is reset.
[0023] Preferably, the camera module is powered by the control module, and the camera module is reset by disconnecting the power supply.
[0024] Preferably, the preset strategy is to analyze the duration of the abnormality through the control module, and the control module resets the detection decoding module and the camera module according to the number of resets and the duration of the abnormality.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] This invention introduces the number of resets as a factor in judging video signal anomalies, thereby determining whether to reset the camera module and the detection decoding module. This can effectively avoid the problem of continuous image failure caused by non-continuous failure of the reversing camera system's hardware and software, and greatly improve the user experience.

[0043] Example 1
[0044] The technical solutions of the present invention will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and are not to be construed as limiting the technical solutions of the present invention.
[0045] Reversing camera system hardware failures caused by non-persistent faults such as electromagnetic compatibility interference, system mismatch, and software bugs can lead to prolonged image display failures due to the inability to quickly reset, giving customers the impression that the reversing camera is malfunctioning. The system provided in this embodiment can quickly restore the reversing camera system from persistent failures caused by non-persistent hardware and software failures through inter-module integration.
[0046] The reversing image self-recovery system provided in this embodiment, such as Figure 1 As shown, it includes a controller module 1, a vehicle power module 2, a reversing camera module 3, and a reverse gear signal transmission module 4.
[0047] The controller module 1 includes a control chip 11, a display 12, a power module 13, a video signal detection module 14, and a video decoding module 15. The power module 13 supplies power to the reversing camera module 3. The vehicle power module 2 supplies power to the controller module 1; its specific structure is not limited and can be a battery, generator, or other power output device. The reversing camera module 3 collects video information about the vehicle's surroundings. The reverse gear signal transmission module 4 inputs the received reverse gear signal to this system.
[0048] The arrangement and connection method of each module in the system provided in this embodiment are as follows: Figure 1 As shown in the diagram, the controller module 1 is connected to the vehicle power module 2, the reversing camera module 3, and the reverse gear signal transmission module 4. Within the controller module 1, the control chip 11 controls the display 12, the power module 13, and the video decoding module 15. The vehicle power module 2 supplies power to the controller module 1, which in turn supplies power to the reversing camera module 3 via a preset control strategy. When powered on, the reversing camera module 3 collects surrounding video information and transmits the collected video signal to the controller module 1 via a video line. Upon receiving the video signal, the controller module 1 decodes it using the video decoding module 15. After decoding, the information is divided into two transmission paths: one path is input to the video signal detection module 14 for video signal detection, and the detection result is sent to the control chip 11; the other path is input to the display 12 for display. The reverse gear signal transmission module 4 sends the reverse gear signal to the controller module 1. After processing by the controller module 1, the display 12 shows the reversing image.
[0049] Specifically, the preset control strategy of the controller module is described. Controller module 1 receives the reverse gear signal from reverse gear signal sending module 4, controls display 12 to display the reversing image, and uses video signal detection module 14 to detect whether the video signal is abnormal. If abnormal, it sends the abnormal status to control chip 11. If control chip 11 detects an abnormal status signal lasting more than 2 seconds and detects that the cumulative number of reset mechanism activations within 5 minutes is less than 2, it activates the reset mechanism and starts counting. This detection of the reset count is used to avoid repeated resets due to continuous hardware failure. Furthermore, if control chip 11 detects an abnormality in the decoding chip, it resets the video decoding module 15; otherwise, it resets the power supply to the reversing camera module 3. In this system, the reversing camera module 3 is powered by control module 1. By controlling (resetting) the camera power supply, control module 1 can solve the problem of continuous reversing image failure caused by non-persistent hardware and software problems.
[0050] Example 2
[0051] The technical solutions of the present invention will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and are not to be construed as limiting the technical solutions of the present invention.
[0052] like Figure 2 As shown, this embodiment provides a method for self-recovery of reversing images, which specifically includes the following steps:
[0053] Step 1: The reverse gear signal sending module 4 sends a reverse gear signal to the controller module 1, and the control chip 11 controls the display 12 to display the reversing image based on the reverse gear signal.
[0054] Step 2: The video signal detection module 14 detects whether the video signal is abnormal. If it is abnormal, it sends the abnormal status to the control chip 11.
[0055] Step 3: If the control chip 11 detects an abnormal state signal lasting for more than 2 seconds and detects that the cumulative number of reset mechanism activations within 5 minutes is less than 2, it activates the reset mechanism and starts counting. This detection of the reset count is used to avoid the problem of repeated resets due to continuous hardware failure.
[0056] Step four: Control chip 11 checks whether the decoding chip is abnormal. If so, proceed to step five; otherwise, proceed to step six.
[0057] Step 5: Reset the video decoding module 15.
[0058] Step 6: Reset the power supply to the reversing camera module 3.
[0059] Step 7, Reset complete.
[0060] The specific embodiments of the present invention have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention.
