[0027] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, this embodiment provides a car safety image prompt system based on camera and radar, which includes a vehicle body communication system, a data acquisition module, a communication module, an MCU module, a HUD lighting circuit, a vibration circuit and a voice prompt circuit;

[0029] The data acquisition module is connected to the vehicle body communication system;

[0030] The vehicle body communication system is connected to the MCU module through the communication module;

[0031] The output end of the MCU module is connected to the input end of the HUD lighting circuit, vibration circuit, and voice prompt circuit.

[0032] like Figure 2 As shown, the data acquisition module of this embodiment includes a radar module and a camera module;

[0033] The radar module is connected to the vehicle body communication system. The radar module uses radar equipment with strong penetration and high anti-interference ability. By transmitting and receiving radio waves, it can perceive the distance, speed and other information of obstacles around the vehicle in real time. The radar data is transmitted from the vehicle body communication system to the MCU module through the communication module for processing.

[0034] The camera module is connected to the vehicle body communication system. The camera module uses a high-resolution, high-sensitivity camera to capture real-time images of the front, left rear, right rear, and rear of the vehicle. The image data is transmitted from the vehicle body communication system to the MCU module through the communication module for processing.

[0035] like Figure 3 As shown, the communication module of this embodiment is an SBC module. The SBC module uses an SBC chip U2 of model UJA1169. The vehicle body communication system is connected to the MCU module through the UJA1169 chip U2.

[0036] like Figure 4As shown, the MCU module of this embodiment uses the SYN6658 chip U1, which is connected to the vehicle body communication system via the SBC chip U2. The output of the SYN6658 chip U1 is connected to the input of the HUD lighting circuit, vibration circuit, and voice prompt circuit. The MCU module combines data from the camera module and radar module to extract the target object's position, speed, and direction information.

[0037] This embodiment uses sound, light and vibration to warn the driver of danger. Figure 5 As shown, the voice prompt circuit uses the HFC5212 chip U3. The input end of the HFC5212 chip U3 is connected to the output end of the MCU module, and the output end of the HFC5212 chip U3 is connected to the speaker BL through the transistor Q2. This embodiment uses the voice inside the car to broadcast, for example, there are pedestrians behind the car, there are vehicles behind the side, and accurately broadcast the type of the target object. Figure 6 As shown in the figure, the HUD lighting circuit uses the TPS929120 chip U4, and the input end of the TPS929120 chip U4 is connected to the output end of the MCU module. On the windshield directly in front of the driver, the HUD provides image and text reminders, so the driver does not need to look back and forth at the alarm on the central control screen and can focus on driving. Figure 7 As shown, the vibration circuit includes a transistor Q5, a diode D5, and a motor M. The output of the MCU module is connected to the base of the transistor Q5 via a resistor R1. The collector of the transistor Q5 is connected to the motor M via a resistor R2. The emitter of the transistor Q5 is grounded. The diode D5 is connected in parallel across the motor M. This embodiment uses steering wheel vibration to alert the driver to potential dangers. In case the driver fails to hear the voice prompt or observe the HUD lighting circuit's warning, a more comprehensive driving safety reminder is provided through physical sensation, allowing the driver to receive prompt information in a timely manner and respond quickly.

[0038] like Figure 2 As shown, the camera and radar-based automobile safety image prompting system of this embodiment further includes a power supply module, and the vehicle body power supply system supplies power to the data acquisition module through the power supply module.

[0039] like Figure 2 As shown, the power supply module of this embodiment includes a first power supply circuit and a second power supply circuit;

[0040] The first power supply circuit supplies power to the radar module;

[0041] The second power supply circuit supplies power to the camera module.

[0042] In this embodiment, the first power supply circuit uses the LM63635-Q1 chip, and the second power supply circuit uses the TPS560430YFQDBVRQ1 chip.

[0043] like Figure 2 As shown, the camera and radar-based automobile safety image prompt system of this embodiment also includes an LDO module. The vehicle body power supply system provides a stable DC voltage power supply to the MCU module, communication module, HUD lighting circuit, vibration circuit and voice prompt circuit through the LDO module.

[0044] The working principle of this utility model is as follows:

[0045] The radar module and camera module are used to collect data on obstacles around the vehicle and real-time images of the surrounding areas. The MCU module receives the data collection information through the communication module and controls the HUD lighting circuit, vibration circuit and voice prompt circuit to provide three types of danger prompts: sound, light and vibration.

[0046] It provides drivers with accurate and timely prompt information through vision, hearing and touch, and can perceive the surrounding environment in real time, thereby effectively avoiding potential risks and improving driving safety. At the same time, it also has the advantages of real-time, accuracy, adaptability and standardization, which is conducive to reducing traffic accidents and ensuring driving safety.

[0047] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
