[0064] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0065] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0066] As described in the related art, the current warning system is mainly for the driver, while the warning for the rear passengers in the car is indeed less. When an emergency occurs, the rear passengers cannot receive the warning information in time and thus cannot take corresponding preventive measures.

[0067] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle warning method, device, storage medium and vehicle based on a starry sky dome. The following first introduces the vehicle warning method based on a starry sky dome provided by the embodiments of the present application.

[0068] The execution subject of the vehicle warning method based on the starry sky top can be a vehicle warning device based on the starry sky top. The vehicle warning device based on the starry sky top can be an electronic device with a processor and memory, such as an on-board electronic device or a non-mobile electronic device. The device can be connected to multiple data acquisition devices on the vehicle respectively. This embodiment of the present application is not specifically limited.

[0069] See also Figure 1 , which shows a flow chart of the implementation of the vehicle warning method based on the starry sky roof provided in an embodiment of the present application, as detailed below:

[0070] Step S110: Obtain the distance information between the vehicle and the target ahead.

[0071] In an embodiment of the present application, the front target can be a dynamic target, such as another vehicle traveling in front of the vehicle; the front target can also be a static target, such as a road sign or sign in front of the vehicle, or a landmark building on the side of the road in front of the vehicle.

[0072] In some implementations, the distance information between the vehicle and the target ahead may be obtained by a radar ranging sensor. For example, the distance between the vehicle and another vehicle traveling ahead may be obtained by a radar ranging sensor disposed directly ahead of the vehicle.

[0073] In some implementations, forward targets can be identified using radar, or by using an image acquisition device to capture images in front of the vehicle and perform image or text recognition to confirm the forward targets. High-precision maps can also be used to obtain information about road signs, signboards, or landmarks in front of the vehicle, and navigation information can be used to directly determine the distance between the vehicle and these forward targets.

[0074] The vehicle may be any fuel vehicle, pure electric vehicle or hybrid vehicle.

[0075] Step S120: Determine whether the distance information meets the preset warning conditions.

[0076] In an embodiment of the present application, it is possible to determine whether the distance between the vehicle and the target ahead meets the preset warning conditions, so that when the distance between the vehicle and the target ahead meets the preset warning conditions, the corresponding warning display of the starry sky top display is controlled.

[0077] In one implementation, the preset warning condition may be the distance between the vehicle and the target ahead.

[0078] In the embodiment of the present application, the distance between the vehicle and the target ahead obtained in step S110 is compared with a preset warning distance to determine whether the distance between the vehicle and the target ahead meets a preset warning condition.

[0079] If the distance between the vehicle and the target ahead is less than a preset distance threshold, i.e., the warning distance, it can be determined that the distance information meets the preset warning conditions.

[0080] In another implementation, the preset warning condition may also be the time it takes for the vehicle to reach the target ahead. Specifically, for a static target, the vehicle's speed information may be obtained, and the time it takes for the vehicle to reach the target ahead may be calculated based on the speed information and the distance between the vehicle and the target ahead. If the time it takes for the vehicle to reach the target ahead is less than a preset time, the distance information is determined to meet the warning condition.

[0081] In some embodiments, when the target ahead is another moving vehicle, calculating the time it takes for the vehicle to reach the target ahead based solely on the current vehicle's speed information may be inaccurate. Therefore, it is necessary to calculate the relative speed between the vehicle and the target ahead in combination with the target ahead's speed information, and then calculate the time it takes for the vehicle to reach the target ahead based on the relative speed and distance. Specifically, when the target ahead is dynamic, the relative speed between the vehicle and the target ahead can be calculated based on the changing distance between the vehicle and the target ahead, as well as the current vehicle's speed information. Furthermore, based on the relative speed and distance between the vehicle and the target ahead, the time it takes for the vehicle to reach the target ahead can be more accurately determined.

[0082] Step S130: If the distance information meets the preset warning condition, the starry sky top is controlled to display the preset warning pattern in a preset manner.

[0083] When the distance information meets the preset warning conditions, the vehicle warning device based on the starry sky roof will control the starry sky roof to display a warning pattern, which can warn the rear passengers in the car.

[0084] In some embodiments, the preset mode can be a flashing mode for early warning. When the distance information meets the preset early warning condition, the starry sky top is controlled to display an early warning pattern in a flashing mode.

[0085] The preset warning pattern can be a red warning signal pattern. The red color is bright and easy to attract the attention of passengers. The pattern can be a variety of patterns, such as a red star pattern, a red heart pattern, etc., and can be set to a variety of patterns, which are not limited here.

[0086] When the distance information meets the preset warning conditions, the starry sky top is controlled to display a red warning signal pattern in a flashing manner.

[0087] In some embodiments, the preset warning conditions can be set as three distance thresholds, namely a first preset distance threshold, a second preset distance threshold, and a third preset distance threshold. Based on the three thresholds, the warning level between the vehicle and the target ahead is determined. The warning level is divided into three warning levels: a first warning level, a second warning level, and a third warning level. The first warning level can be the lowest warning level, and the third warning level can be the highest warning level. Of course, different warning levels and different levels of severity can also be set according to the user's usage scenario.

[0088] Specifically, according to the distance information, the first preset distance threshold, the second preset distance threshold and the third preset distance threshold, wherein the first preset distance threshold is the largest and the third preset distance threshold is the smallest.

[0089] When the distance information is less than the first preset distance and greater than or equal to the second preset distance threshold, the warning level between the vehicle and the target ahead is the first warning level. When the distance information is less than the second preset distance and greater than or equal to the third preset distance threshold, the warning level between the vehicle and the target ahead is the second warning level. When the distance information is less than the third preset distance threshold, the warning level between the vehicle and the target ahead is the third warning level.

[0090] Then, based on the above-mentioned warning levels, the starry sky top is controlled to display the preset warning pattern in the preset area in a preset manner.

[0091] The preset areas can be multiple zones on the starry sky ceiling, such as dividing the starry sky ceiling into three annular zones: an outer annular zone, a middle annular zone, and an inner annular zone. The starry sky ceiling can also be divided into several figure-8 zones, which is not limited here. Based on different warning levels, preset warning patterns can be displayed in different preset areas, allowing rear passengers to more intuitively perceive the warning level and take appropriate measures in a timely manner.

[0092] Specifically, when the warning level is the first warning level, the inner ring area of ​​the starry sky top is controlled to display a red warning signal pattern in a flashing manner. When the warning level is the second warning level, the inner ring area and the middle ring area of ​​the starry sky top are controlled to display a red warning signal pattern in a flashing manner. When the warning level is the third warning level, the outer ring area, the middle ring area, and the inner ring area of ​​the starry sky top are controlled to display a red warning signal pattern in a flashing manner.

[0093] In addition, the flashing frequency and brightness of the warning signal pattern can be adjusted according to different warning levels. For example, the starry sky top can be controlled to display a red warning signal pattern at different flashing frequencies in the corresponding preset area. The flashing frequency is related to the warning level, and gradually becomes faster as the warning level increases. The starry sky top can also be controlled to display a red warning signal pattern at different brightness levels in the corresponding preset area. The brightness is also related to the warning level, and the brightness gradually becomes brighter as the warning level increases.

[0094] The vehicle warning method based on a starry sky roof provided in this application first obtains distance information between the vehicle and the target ahead, then determines whether the distance information meets preset warning conditions. Finally, if the distance information meets the preset warning conditions, the starry sky roof is controlled to display a preset warning pattern in a preset manner. In this way, by promptly controlling the starry sky roof to display a preset warning pattern in a preset manner when the distance information meets the preset warning conditions, rear passengers in the vehicle can be promptly reminded to take appropriate measures to ensure their safety.

[0095] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
