[0020] The following, with reference to the accompanying drawings, further illustrates the specific implementation methods of the present invention through the description of the embodiments, with the aim of helping those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution of the present invention and to facilitate its implementation. It should be noted that the terms "first" and "second" in this application are only used to facilitate the description of the technical solution to distinguish different components and are not intended to limit this application. To make the technical solution of the present invention more clear, the present invention is explained through the following embodiments.
[0021] An integrated driving recorder system, such as Figure 1 As shown, the system includes a body controller, a panoramic controller (AVM controller), a surround-view camera, and a display device. The panoramic controller is connected to the body controller, the surround-view camera, and the display device respectively; the body controller is also connected to the display device via a CAN bus, supporting the body controller to control the display device.
[0022] In order to realize the function of driving record, this embodiment configures a panoramic controller, such as Figure 2As shown, the device includes a decoder, an encoder, a MCU, a CPU, a CAN transceiver module, a power supply module, and a storage module, and has the advantages of small size and high integration.
[0023] Specifically, the power supply module of the embodiment is connected with the vehicle body controller, the MCU, the decoder, and the CPU, and is also connected with the surround-view camera. The vehicle body controller is configured to provide a working voltage BAT for the panoramic controller. The BAT voltage is distributed and processed by the power supply module and is used to supply power to the MCU, the decoder, and the CPU. Specifically, the power supply module includes a first DCDC converter, a second DCDC converter, a low dropout regulator (LDO), and a first power supply chip (PMIC). The BAT voltage of the vehicle body controller is used to supply power to the surround-view camera (CAM POWER) through the LDO. The BAT voltage of the vehicle body controller is also used to supply power to the second DCDC converter, the MCU, and the first power supply chip after being stepped down to 5V by the first DCDC converter. The second DCDC converter further steps down the output voltage 5V of the first DCDC converter to 3.3V and 1.2V and outputs the voltage to the decoder. The first power supply chip processes the output voltage 5V of the first DCDC converter to obtain a plurality of output voltages (including 1.1V, 1.5V, 1.8V, 3.0V, 3.3V, 1.2V, etc.) and distributes the voltages to the pins of the CPU.
[0024] The MCU of the embodiment is connected with the vehicle body controller through the CAN transceiver module. The vehicle body controller can send vehicle information such as a steering light switch information, a gear information, a vehicle speed information, and an ignition signal (IGN) to the MCU through the CAN transceiver module. The vehicle body controller of the embodiment also includes a panoramic start switch (AVM) which is connected with the panoramic controller and is configured to enable the panoramic controller to start the driving record function. Correspondingly, the panoramic start switch is also sent to the MCU through the CAN transceiver module. After receiving and recognizing the information, the MCU can send the information to the CPU for processing through the UART bus protocol, so as to record and display the information. Meanwhile, if the panoramic controller also reserves an LED lamp for state display, the MCU also supports sending a PWM signal to control the LED lamp.
[0025] The CPU of the embodiment is connected with the MCU, the decoder, the encoder and the storage module respectively; the decoder is connected with the surround view camera; and the encoder is connected with the display device. After receiving the information of the MCU, the CPU uploads the AHD image (analog high-definition image) of the surround view camera when identifying that the driving record function is turned on, decodes the AHD image by the decoder and then uploads the AHD image to the CPU. The CPU is responsible for processing the image, such as distortion correction, bird's-eye view transformation and panoramic splicing. Meanwhile, the CPU parses the whole vehicle information to be displayed from the information uploaded by the MCU. The processed image and the parsed whole vehicle information are output to the display device for display by the encoder. The processed image and the parsed whole vehicle information can be saved in the storage module, and the storage module can be set to cyclic recording, and the recording time is determined by the size of the storage unit, which can be set and expanded by the customer.
[0026] The storage module of the embodiment includes an EMMC (an embedded storage device, used for long-term storage of the operating system and application data of the CPU), a DDR3 (synchronous dynamic random access memory, used for temporary data storage and access for CPU operation), and an SDcard (a removable storage device, responsible for storing the processed image and the parsed whole vehicle information of the CPU in the embodiment). The EMMC, the DDR3 and the SDcard are connected with the CPU respectively.
[0027] Further, the surround view camera used in the embodiment includes a lens (LENS), an image sensor (SENSOR), an image processor (ISP), a memory (FLASH), a video amplifier (VIDEO AMP) and a second power chip (PMIC), as shown in the accompanying drawings. Figure 3
[0028] Specifically, the second power chip is connected with the panoramic controller, the image sensor and the image processor respectively, and is used for distributing the voltage provided by the panoramic controller to the image sensor and the image processor after processing. In the embodiment, the second power chip directly outputs 8V output by the panoramic controller to the image processor, and also provides 3.3V, 1.8V and 1.2V obtained by step-down of the 8V voltage to each pin of the image sensor.
[0029] The image processor is connected to the image sensor, memory, and video amplifier, respectively; the video amplifier is connected to the panoramic controller. In this embodiment, the lens is used to generate an optical image and project it onto the photosensitive surface of the image sensor. The image sensor converts the optical signal into an electrical signal, which is then converted into a digital signal through A / D conversion. The digital signal is sent to the image processor for processing such as gamma correction, automatic white balance, automatic gain, and automatic exposure, and then outputs an analog high-definition video signal in AHD format. The signal is then amplified by the video amplifier and output to the panoramic controller for recording and display.
[0030] To achieve comprehensive vehicle monitoring, the system in this embodiment uses four surround-view cameras, positioned at the front, rear, left, and right of the vehicle. To further enhance image clarity, the surround-view cameras in this embodiment utilize fisheye cameras with a resolution of 1280×960 pixels, a dynamic range of 120dB, a horizontal field of view of 195°, and a frame rate of 25 FPS.
[0031] In this embodiment, the vehicle body controller, surround-view camera, and display device can all be built-in components of the vehicle. However, in existing vehicles, they are not used for driving recorders. However, this application implements the driving recorder function through a corresponding panoramic controller. Unlike existing driving recorders, this application does not require the installation of additional cameras or other equipment. Instead, it only requires a small, highly integrated panoramic controller, which is easy to install and reduces costs. At the same time, the design of this application is not limited to driving recorders and can also be applied to other fields such as autonomous driving navigation, thereby achieving the purpose of reducing costs and simplifying the installation process.
[0032] At the same time, the present application also proposes a vehicle, which is equipped with the above-mentioned integrated driving recorder system.
[0033] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
