[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] To reduce the impact of blind spots on drivers, engineers have designed blind spot monitoring systems, which are usually installed near the A-pillar or door handles in the cockpit. They use radar or cameras to detect the vehicle's surroundings and display environmental information around the vehicle on a screen in the cockpit. However, traditional blind spot monitoring systems have a small visual area, and the driver's judgment range is still limited, making it impossible to observe the vehicle environment well and avoid risks.

[0029] According to an embodiment of the present invention, a method embodiment of a vehicle warning is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] In order to solve the problem that the driver cannot avoid danger in time due to blind spots, a vehicle warning system can be configured on the vehicle. The embodiment of the present invention provides a vehicle warning method. Figure 1 is a flow chart of a vehicle warning method according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0031] Step S102 : Acquire driving information and environmental information of the vehicle, wherein the environmental information is used to represent object information of original objects detected around the vehicle.

[0032] Since the A-pillar creates a blind spot for the driver when starting or turning, in order to accurately determine whether a vehicle warning is needed and avoid the impact of the A-pillar blind spot, the vehicle driving information in the above steps can be information related to vehicle starting and turning. For example, it can include but is not limited to: vehicle speed and steering wheel offset angle. The equipment for obtaining vehicle information includes but is not limited to electromagnetic or Hall-type vehicle speed sensors, steering wheel angle sensors and other sensor devices. The original objects in the above steps can be pedestrians, vehicles, obstacles, etc. around the vehicle that may affect vehicle starting and turning, but are not limited to these. The object information can be the relative position of the original object and the vehicle, the direction and speed of the original object, etc. The equipment for obtaining environmental information includes but is not limited to detection equipment such as cameras and radars.

[0033] In an optional embodiment, the controller MCU of the early warning system can collect information sensed by the sensor device in real time to obtain vehicle information. At the same time, it can receive the detection signal output by the detection device and process the detection signal, for example, performing image recognition on the image taken by the camera and identifying the radar signal collected by the radar, thereby obtaining object information of the original objects around the vehicle.

[0034] Step S104: determining a warning result of the vehicle based on the driving information and the environmental information, wherein the warning result is used to indicate whether to issue a warning to the vehicle.

[0035] Since the vehicle's A-pillar blind spot restricts the driver's starting and turning, the warning system can combine the vehicle's current driving information and environmental information to determine whether the vehicle is starting or turning, and whether there are other pedestrians, vehicles, and other original objects near the vehicle that affect the vehicle's driving safety, and then determine whether a warning is needed. When the vehicle driving information indicates that the vehicle is starting or turning, or the environmental information indicates that there are original objects around the vehicle that affect the vehicle's driving safety, it can be determined that a warning is needed to ensure the safety of the driver and pedestrians in the blind spot.

[0036] Step S106 , in response to the warning result being a warning for the vehicle, controlling the display screen to display a warning image, wherein the warning image is collected by a target device installed on the outer side of the A-pillar of the vehicle.

[0037] The display screens in the above steps can include foldable and non-foldable screens. The foldable screen can be mounted on the inside of the vehicle's A-pillar and can consist of two 8-inch flexible displays hinged together. An H-shaped full-bridge motor can be constructed using MOS transistors to control the forward and reverse rotation of the motor, thereby controlling the hinge's opening and closing, hovering angle, and other aspects. The non-foldable screen can be a 5-inch display, serving as a secondary screen. The target device can be a device capable of capturing real-time images, including but not limited to a camera, mounted on the outside of the vehicle's A-pillar. The warning image can be an image of the vehicle's surroundings captured by the camera.

[0038] In an optional embodiment, after the target device acquires the warning image, the warning system displays the image result on a display screen in real time and feeds it back to the driver, so that the driver can judge whether there is any abnormality in the surrounding environment based on the warning image and respond accordingly.

[0039] By detecting the vehicle's driving status and the vehicle's surrounding environment, it is determined whether a warning is needed. If a warning is needed, the warning image is reflected in real time on the screen in the vehicle's cockpit, helping to expand the driver's visual area, thereby achieving the technical effect of visualizing the car's A-pillar blind spot, and thus solving the technical problem that the driver cannot avoid danger in time due to the large blind spot in the vehicle's cockpit.

[0040] Optionally, in one embodiment of the present invention, the aforementioned step S104, based on driving information and environmental information, determines the warning result of the vehicle, including: based on the driving information, determining whether the vehicle is in a warning state, wherein the warning state is used to characterize that the vehicle speed is less than a preset speed, or the vehicle changes lanes; based on the environmental information, determining whether there is a target object in the original object, wherein the target object is used to characterize an object close to the vehicle; in response to the vehicle being in a warning state, or the target object being in the original object, determining that the warning result is to warn the vehicle; in response to the vehicle not being in a warning state, and the target object not being in the original object, determining that the warning result is not to warn the vehicle.

[0041] Figure 2 This is a flow chart of a method for determining a vehicle warning result according to an embodiment of the present invention. The specific steps of determining the vehicle warning result are as follows:

[0042] Step S202: Determine whether the vehicle is in a warning state based on the driving information.

[0043] The above-mentioned warning state refers to a situation where the driver needs to pay attention to the safety of the vehicle and personnel. Generally speaking, due to the obstruction of the driver's line of sight by the A-pillar, the driver cannot observe the environmental conditions in front of the left side of the vehicle very well. When the vehicle is just started or the vehicle is turning, it is easy to cause a traffic accident, such as hitting a pedestrian or an obstacle. Therefore, from a safety perspective, this application proposes to monitor the two situations where traffic accidents are prone to occur, namely, when the vehicle is just started and when the vehicle is turning, to determine whether a vehicle warning is needed.

[0044] In an optional embodiment, the vehicle's current speed can be used to determine whether the vehicle has just started. Engineers can preset a first speed threshold, such as 5 km / h. If the speed sensor detects that the vehicle's current speed is less than 5 km / h, it means that the vehicle has just started, and the warning system determines that the vehicle is in a warning state. Otherwise, it means that the vehicle is traveling normally, and the warning system determines that the vehicle is not in a warning state. In addition, the vehicle's current steering wheel offset angle can be used to determine whether the vehicle is turning or changing lanes. Engineers can preset a steering wheel offset angle threshold, such as 5°. If the steering wheel angle sensor detects that the steering wheel offset angle is greater than 5°, it means that the vehicle is turning or changing lanes, and the warning system determines that the vehicle is in a warning state. Otherwise, it means that the vehicle is traveling normally, and the warning system determines that the vehicle is not in a warning state.

[0045] Step S204: determining whether a target object exists in the original object based on the environment information.

[0046] The above-mentioned target object refers to an object close to the vehicle, such as a pedestrian, vehicle, obstacle, etc. After the original object is obtained in the aforementioned step S102, image recognition of the original object can be performed, or radar detection can be used to determine whether there is an object approaching the vehicle. The radar is installed near the camera. For specific methods, please refer to the relevant image recognition and radar detection literature.

[0047] Step S206 , in response to the vehicle being in a warning state, or the target object existing in the original object, determining that the warning result is to issue a warning to the vehicle.

[0048] If the vehicle is currently in a warning state, or if it determines based on environmental information that an object is approaching the vehicle, the entire warning system will issue an alarm. Simultaneously, the warning system will display real-time images of the vehicle's surroundings, acquired through monitoring and detection equipment such as cameras and radar, on the in-cabin display screen to alert the driver to take immediate action. Warning methods may include, but are not limited to, a buzzer sounding at a certain frequency, a flashing signal on the display screen, such as a warning tone when the vehicle starts, a clicking sound when turning, or a signal light displayed on the display screen.

[0049] Optionally, in this embodiment, engineers can also preset a target object distance threshold. When the system determines that a target object is approaching the vehicle, it can use radar to detect whether the distance between the target object and the vehicle is less than the target object distance threshold. If the distance is less than the threshold, an early warning is issued. If the distance is not less than the threshold, no early warning is issued, thereby increasing the maneuverability of the vehicle while ensuring the safety of the vehicle and the target object.

[0050] Optionally, in this embodiment, engineers can also set that the closer the distance between the target object and the vehicle, the higher the frequency of the buzzer, and the faster the frequency of the flashing signal on the display, to remind the user to avoid danger in time.

[0051] Corresponding to the above step S1046, the method further includes: in response to the vehicle not being in the warning state and the target object not existing in the original object, determining that the warning result is not to issue a warning to the vehicle.

[0052] If the vehicle is not currently in a warning state, that is, when the vehicle is driving normally and not turning or changing lanes, and detection equipment such as cameras or radars do not detect a target object approaching the vehicle, the entire warning system determines not to issue a warning.

[0053] Optionally, if the engineer presets a target object distance threshold, when the vehicle is not currently in a warning state and there is a target object approaching the vehicle, but the distance between the target object and the vehicle is not less than the object distance threshold, the entire warning system will not issue a warning.

[0054] Through the above method, the vehicle's driving information and environmental information are combined to determine whether the vehicle needs to enter the warning state. After entering the warning state, the warning system issues an alarm to remind the driver to pay attention to avoid danger in time. While ensuring the safety of vehicles and pedestrians, it can improve the warning system's ability to adapt to diverse environments and increase the vehicle's maneuverability.

[0055] In order to more clearly show the structure of the early warning system, such as Figure 3 As shown, Figure 3 2 is a schematic structural diagram of an early warning system according to an embodiment of the present invention.

[0056] Figure 3 The first part is the environmental information acquisition part, which is composed of a camera and a warning radar, and is used to obtain the warning image of the vehicle's A-pillar blind spot; the second part is the warning result determination part, which is controlled by a domain controller. The controller is used to determine the warning status and make a warning response based on the warning status; the third part is the warning response part, including a buzzer and a display. As shown in the third part, the display consists of two parts, one is a larger foldable display, which is controlled by a motor and a hinge, and the other is a smaller non-folding display, which is used as a sub-screen of the foldable display.

[0057] Optionally, in one embodiment of the present invention, the warning system can also adaptively select a display screen to display environmental information around the vehicle, as shown in the aforementioned step S106, the display screen includes: a folding screen and a non-folding screen, and the folding screen is installed on the inside of the A-pillar of the vehicle, wherein controlling the display screen to display the warning image includes: determining the target display screen based on driving information; controlling the target display screen to display the warning image.

[0058] Specifically, when the warning system determines that the vehicle is not currently in a warning state, in order to avoid the large-area vehicle environment information image affecting the driver, the system opens the non-folding screen and displays the image captured by the camera on the display screen; when the warning system determines that the vehicle is currently in a warning state, in order to enable the driver to clearly understand the image of the A-pillar blind spot, the system unfolds the display screen, displays the image captured by the camera on the display screen, and reminds the driver to pay attention.

[0059] like Figure 3 As shown, the aforementioned display screens include two types: foldable and non-foldable. Foldable screens are generally larger than non-foldable screens. Considering the driver's visual experience and comfort, two 8-inch flexible displays are usually selected to form a foldable screen, and a 5-inch standard display is used as the non-foldable screen. Under normal circumstances, the displays are kept closed. The displays can be used simultaneously, or one can be selected based on vehicle information. Specifically, determining the target display screen based on driving information includes: determining the target display screen as a foldable screen in response to the vehicle speed being less than or equal to a preset speed; and determining the target display screen as a foldable screen in response to the vehicle speed being greater than a preset speed.

[0060] For example, engineers can preset a second speed threshold, taking 40km / h as an example. When the vehicle speed is less than 40km / h, a larger folding screen is selected to display the vehicle environment information image, so that the driver can clearly observe the A-pillar blind spot information and respond to emergencies in time; when the vehicle speed is not less than 40km / h, a smaller non-folding screen is selected to display the vehicle environment information image, so as to avoid affecting the driver's perspective when the vehicle is driving at high speed, and further avoid traffic accidents caused by distraction due to display screen images.

[0061] Since the material of the folding screen is generally flexible, when the target display screen is a folding screen, controlling the target display screen to display a warning image includes: controlling the folding screen to unfold through a motor; decoding the warning image to obtain a decoded image; and controlling the unfolded folding screen to display the decoded image.

[0062] like Figure 3As shown, the controller controls the forward and reverse rotation of the motor by building an H-type full-bridge through the MOS tube, thereby controlling the opening and closing of the hinge, and then controlling the opening and closing of the folding screen. When the vehicle is in the warning state and the speed is less than the speed threshold of 40km / h, the controller sends a command to the motor, the motor rotates forward, controls the hinge to open, and then opens the folding screen, decodes and displays the warning image captured by the camera and other monitoring equipment, and the non-folding screen remains closed; when the vehicle is in the warning state and the speed is not less than the speed threshold of 40km / h, if the folding screen is currently open, the controller sends a command to the motor, the motor rotates, controls the hinge to close, and then closes the folding screen, and opens the non-folding screen at the same time, and decodes and displays the warning image captured by the camera and other monitoring equipment.

[0063] By setting up two display screens, the driver can effectively obtain vehicle environment information in different states. When the vehicle speed is slow, a larger folding screen is selected to ensure that the driver can clearly obtain environmental information; when the vehicle speed is fast, a smaller non-folding screen is selected to ensure that the driver is not affected by the large screen, thereby ensuring the driver's safety. When the larger folding screen is not in use, the folding screen will be closed to reduce the impact on the driver while saving space in the car.
