[0035] The invention provides an automobile, including a system and method for visually reminding the automobile to drive safely.
[0036] The following is a detailed description of a system and method for visually reminding safe driving of an automobile according to the present invention.
[0037] The present invention provides a system for visually reminding safe driving of an automobile, comprising a vehicle distance detection module 1, a control module 2, a user input module 3 and an external display screen 4, wherein the vehicle distance detection module 1 uses a millimeter wave radar to detect the distance between the automobile and the following vehicle, and transmits the collected vehicle distance information to the control module 2. The millimeter wave radar in the present invention has a long detection distance, which meets the requirement that the automobile detects the position of the following vehicle to determine the vehicle distance.
[0038] The control module 2 uses a body domain controller to receive the vehicle distance information collected by the vehicle distance detection module 1, calculate the safe distance of the rear vehicle and decide whether to issue a prompt. Specifically, the control module 2 calculates the relative speed of the rear vehicle relative to the car according to the change in the vehicle distance, and then adds it to the speed of the car itself to obtain the speed of the rear vehicle. After obtaining the speed of the rear vehicle, the safe distance between the cars is obtained according to the relevant fixed distance, and the safe distance and the real-time vehicle distance are compared. When the real-time vehicle distance is less than the safe distance, the control module 2 sends a text message to the external display screen 4 to prompt the rear vehicle. The body domain controller in the embodiment of the present invention is a body domain controller (BDCU) of Jingwei Hengrun.
[0039] The user input module 3 uses a central control screen and a microphone, the central control screen is used to transmit the text information input by the user to the control module 2, and the microphone is used to transmit the voice information input by the user to the control module 2. The central control screen and the microphone in the present invention meet the requirements of the user to input information. When it is inconvenient for the user to input information, the user can input information through the microphone, which prevents the user from being distracted and affecting driving, thereby improving the safety of automobile driving.
[0040] The peripheral display screen 4 adopts an LED display screen, which is used to display the voice information input by the control module 2 to prompt the following vehicle.
[0041] The output end of the millimeter-wave radar is connected to the input end of the body domain controller, the output end of the central control screen and the output end of the microphone are respectively connected to the input end of the body domain controller, and the output end of the body domain controller is connected to the input end of the LED display screen.
[0042] A method for visually reminding safe driving of an automobile according to the present invention is as follows:
[0043] The vehicle distance detection module 1 detects the vehicle distance between the vehicle and the following vehicle in real time, and transmits the vehicle distance information to the control module 2.
[0044] The control module 2 calculates the speed of the rear vehicle in real time according to the change of the distance between the vehicles. Specifically, the control module 2 calculates the relative speed between the rear vehicle and the car according to the change of the distance between the vehicles. When the distance between the vehicles decreases, the control module 2 adds the relative speed to the speed of the car to obtain the speed of the rear vehicle; when the distance between the vehicles increases, the control module 2 subtracts the relative speed from the speed of the car to obtain the speed of the rear vehicle. The safe distance between the car and the rear vehicle is determined according to the speed of the rear vehicle. In an embodiment of the present invention, when the speed of the rear vehicle is above 100km / h, the safe distance is above 100 meters. When the speed of the rear vehicle is between 60km / h and 100km / h, the safe distance is 80 meters. When the speed of the rear vehicle is between 40km / h and 60km / h, the safe distance is 50 meters. When the speed of the rear vehicle is between 20km / h and 40km / h, the safe distance is 30 meters. When the speed is below 20km / h, the safe distance is 10 meters. After determining the speed of the rear vehicle, the control module 2 compares the real-time vehicle distance with the safe vehicle distance. When the distance between the vehicle and the rear vehicle is less than the safe vehicle distance, the control module 2 outputs text information to the external display screen 4. Specifically, the control module 2 outputs the text message "Please slow down" to the external display screen 4 to prompt the rear vehicle. The present invention protects the personal safety of the user by detecting the distance between the vehicle and the rear vehicle and prompting the rear vehicle when the distance is less than the safe vehicle distance.
[0045] In the present invention, when the rear vehicle turns on the high beam and affects the driving of the car, the user can input the text message of "please turn off the high beam" to the control module 2 through the central control screen, and the control module 2 displays the text message of "please turn off the high beam" on the external display screen 4. It should be noted that the input of information through the central control screen is generally completed by the co-driver. When the user is driving alone, the user inputs the voice message of "please turn off the high beam" to the control module 2 through the microphone, and the control module 2 converts the voice message into a text message and displays the text message of "please turn off the high beam" on the external display screen 4. When an emergency occurs in front, the user can input information in the above manner to prompt the rear vehicle. The text prompt function in the present invention can be applied to different scenarios, meeting the needs of users to convey information to the rear vehicle under different conditions.
[0046] The present invention reduces the probability of rear-end collision of automobiles and protects the personal safety of users.
[0047] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
