[0002] In order to facilitate off-road vehicles' outdoor travel, many off-road vehicles use a compass on the instrument screen or central control entertainment screen to display the vehicle's current direction of travel, providing effective direction information for the owner's outdoor travel.

[0003] At present, when the compass points, it usually determines the current compass direction based on the current collected vehicle azimuth angle and the angle interval corresponding to each preset direction. However, in actual driving, when the azimuth angle fluctuates within the critical value of any angle interval, the compass will jump back and forth between the two directions, so that the compass will appear to shake on the display screen. Summary of the invention

[0004] The embodiments of the present application provide a compass display method, device, vehicle and storage medium, which can solve the problem that when the azimuth angle fluctuates between two angle ranges, the compass will frequently switch between two directions, resulting in a poor user experience.

[0008] Get the target orientation angle of the vehicle at the current moment;

[0009] If the target azimuth angle is within the target angle range, the compass direction display is maintained.

[0011] A first determination module, used to determine a first direction pointed by the compass at a previous moment;

[0012] A second determination module, configured to determine a target angle interval corresponding to the first direction according to a preset anti-shake angle and a first preset angle interval corresponding to the first direction; the target angle interval includes the first preset angle interval;

[0018] In a sixth aspect, an embodiment of the present application provides a vehicle, comprising a compass and a compass display device, wherein the compass display device is used to display the direction of the compass when executing the method of the first aspect above.

[0019] Compared with the prior art, the embodiment of the present application has the following beneficial effects: after determining the first direction pointed by the compass at the last moment, a target angle interval larger than the first preset angle interval and including the first preset angle interval is re-determined according to the preset anti-shake angle and the first preset angle interval corresponding to the first direction. Afterwards, when it is determined that the target azimuth angle of the vehicle at the current moment is in the target angle interval, the direction of the compass is maintained.

Avoid the target azimuth angle at the critical value of the first preset angle, when it changes in a range lower than the anti-shake angle, and the direction of the compass also keeps shaking. Moreover, when it changes in a range lower than the anti-shake angle, even when the target azimuth angle exceeds the first preset angle interval, but does not exceed the target angle interval, it can be considered that the actual forward direction of the vehicle at the current moment does not deviate significantly from the direction of the compass. Furthermore, while ensuring that the direction of the compass is consistent with the forward direction of the vehicle, the compass is prevented from shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0027] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0028] In order to facilitate off-road vehicles' outdoor travel, many off-road vehicles use a compass on the instrument screen or central control entertainment screen to display the vehicle's current direction of travel, providing effective direction information for the owner's outdoor travel.

[0029] Exemplarily, in the instrument screen or the central control entertainment screen, the display method of the compass is usually: according to the number of directions that can be displayed on the interface, different direction areas are divided. At present, the commonly used display method usually divides eight direction areas. Specifically, there are eight directions: north, northeast, east, southeast, south, southwest, west, and northwest. Among them, the angle interval corresponding to each direction can be: north: [0, 22] and [338, 360]; northeast: [23, 67]; east: [68, 112]; southeast: [113, 157]; south: [158, 202]; southwest: [203, 247]; west: [248, 292]; northwest: [293, 337].

[0030] For details, please refer to Figure 1 , Figure 1 Schematic diagram of an application scenario of a compass in a compass display method provided in an embodiment of the present application. Figure 1 As shown, when the acquired azimuth angle is 0°, the compass points to the north direction and displays the current azimuth angle at the same time, for example, 0°, north, so that the owner can more intuitively determine the driving direction of the vehicle.

[0031] However, in actual driving, in order to maintain the pointing accuracy of the compass, the prior art will cause the compass to jump back and forth between two directions when the azimuth angle fluctuates within a critical value of any angle range, so that the compass will appear to be jittery on the screen. At this time, this situation may affect the vision of the driver, and further affect the driver's driving and user experience.

[0032] Based on this, when the azimuth angle fluctuates within a critical value of any angle interval, in order to prevent the compass from shaking, an embodiment of the present application provides a compass display method, which can be applied to a compass display device, for example, a vehicle controller.

[0033] See also Figure 2 , Figure 2 A flow chart of a vehicle control method according to an embodiment of the present application is shown, and the method comprises the following steps:

[0034] S201, determining a first direction pointed by the compass at the last moment.

[0035] In one embodiment, the compass usually obtains the vehicle's azimuth data in real time, for example, the azimuth angle corresponding to the driving direction. Therefore, it can be considered that at the last moment, the compass display device has obtained the first direction pointed by the compass according to the driving control method in the embodiment of the present application. Based on this, the compass display device can directly determine the first direction.

[0036] S202: Determine a target angle interval corresponding to the first direction according to a preset anti-shake angle and a first preset angle interval corresponding to the first direction; the target angle interval includes the first preset angle interval.

[0037] In one embodiment, the preset angle interval can be set according to actual conditions. For example, when the compass can point to eight direction areas, the preset angle interval corresponding to each direction can be as shown above. When the compass only needs to point to four direction areas, the preset angle interval corresponding to each direction can be reset, and there is no limitation on this.

[0038] The first preset angle interval is an angle interval corresponding to the first direction. Exemplarily, when the first direction is north, the corresponding first preset angle interval may be [0, 22] and [338, 360].

[0039] In one embodiment, the anti-shake angle may be pre-set according to actual conditions, and may be used to fine-tune the first preset angle interval to obtain a target angle interval corresponding to the first direction. Exemplarily, the anti-shake angle may be 2.5°.

[0040] It should be noted that when the target angle interval is obtained, the target angle interval should include the original first preset angle interval.

[0041] In a specific embodiment, the compass display device may first determine the first angle maximum value and the first angle minimum value in the first preset angle interval, and then generate a target angle interval according to the anti-shake angle, the first angle maximum value and the first angle minimum value.

[0042] For example, the compass display device may determine the sum of the first angle maximum value and the anti-shake angle as the second angle maximum value, and the difference between the first angle minimum value and the anti-shake angle as the second angle minimum value. Finally, the target angle interval is generated according to the second angle maximum value and the second angle minimum value.

[0043] At this time, the range of the generated target angle interval is not only larger than the range of the original first preset angle interval, but also includes the original first preset angle interval. Exemplarily, when the first preset angle interval is [α, β] and the anti-shake angle is μ, the corresponding target angle interval will be [α-μ, β+μ].

[0044] It should be noted that when generating the target angle interval, the original maximum value of the first preset angle interval needs to be increased and the original minimum value of the interval needs to be decreased, rather than just increasing the original maximum value of the interval or decreasing the original minimum value of the interval.

[0045] It should be added that the method of obtaining the target angle range based on the above-mentioned second angle maximum value and second angle minimum value is only an example. In other embodiments, the vehicle can also determine the target angle range based on other examples.

[0046] Exemplarily, when it is determined that the number of times the compass repeatedly points to any two preset directions within a preset time period reaches a preset number, the compass display device can obtain the first azimuth angle corresponding to each time the compass points to the first preset direction, and the second azimuth angle corresponding to each time the compass points to the second preset direction. Then, the maximum first azimuth angle is determined from the multiple first azimuth angles, and the maximum second azimuth angle is determined from the multiple second azimuth angles. Then, the absolute value of the difference between the maximum second azimuth angle and the maximum first azimuth angle is determined as the anti-shake angle.

[0047] It should be noted that when determining the anti-shake angle through the above example, the compass display device needs to pre-determine whether the compass repeatedly points to any two preset directions within a preset time period and reaches a preset number of times, that is, the compass appears to be animated and shaken on the display screen.

[0048] S203: Obtain the target azimuth angle of the vehicle at the current moment.

[0049] In one embodiment, the target azimuth angle is an angle obtained by collecting the azimuth data of the vehicle at the current moment. The compass display device may obtain the first azimuth angle of the vehicle collected by the compass at the current moment as the target azimuth angle. Alternatively, the second azimuth angle of the vehicle collected by the preset map navigation module at the current moment may be obtained as the target azimuth angle, which is not limited thereto.

[0050] It should be understood that the compass has the function of collecting azimuth data (first azimuth angle), so the compass display device can directly obtain the target azimuth angle. Similarly, a virtual compass is usually provided in the map navigation module to indicate the azimuth angle. For example, a virtual compass is usually displayed in the upper left corner of the Amap module, and the direction of the virtual compass is usually the direction of the vehicle. During the driving of the vehicle, the virtual compass usually rotates with the direction of the vehicle, which is not described in detail.

[0051] In a specific embodiment, in order to accurately obtain the target azimuth angle, the compass display device can determine the target azimuth angle based on the first azimuth angle and the second azimuth angle at the same time. Exemplarily, the compass display device can determine the weighted sum of the first azimuth angle and the second azimuth angle as the target azimuth angle. The sum of the weight of the first azimuth angle and the weight of the second azimuth angle is 1, and the weight corresponding to the first azimuth angle and the weight corresponding to the second azimuth angle can be set according to actual conditions, and there is no limitation on this.

[0052] S204: If the target azimuth angle is within the target angle range, maintain the compass direction display.

[0053] In one embodiment, when the target azimuth angle is within the target angle range, the compass display device can still maintain the display of the compass direction, that is, still display the direction of the compass on the instrument screen or the central control entertainment screen as the first direction, thereby avoiding the compass from shaking.

[0054] In this embodiment, after determining the first direction pointed by the compass at the last moment, a target angle interval that is larger than the first preset angle interval and includes the first preset angle interval is re-determined according to the preset anti-shake angle and the first preset angle interval corresponding to the first direction. Afterwards, when it is determined that the target azimuth angle of the vehicle at the current moment is in the target angle interval, the compass direction display is maintained. Based on this, the above method can be used to maintain the compass direction when the target azimuth angle at the current moment is not in the original first preset angle interval, but in the target angle interval determined according to the anti-shake angle. Avoid the target azimuth angle at the critical value of the first preset angle, when it changes in a range lower than the anti-shake angle, and the compass direction also keeps shaking. Moreover, when it changes in a range lower than the anti-shake angle, even if the target azimuth angle exceeds the first preset angle interval, but does not exceed the target angle interval, it can be considered that the actual forward direction of the vehicle at the current moment does not deviate significantly from the direction of the compass. Furthermore, while ensuring that the direction of the compass is consistent with the forward direction of the vehicle, the compass is prevented from shaking.

[0055] In another embodiment, when the target azimuth angle at the current moment is not within the target angle range, the compass display device needs to determine the second direction corresponding to the target azimuth angle based on the association between the preset direction and the preset angle range, and then control the compass to point to the second direction.

[0056] It is understandable that when the target azimuth angle is not within the target angle interval, it can be considered that the target azimuth angle has obviously deviated from the first direction. Therefore, in order to accurately represent the driving direction of the vehicle, the compass display device needs to re-determine the second direction based on the preset angle interval originally corresponding to each preset direction.

[0057] In one embodiment, the association relationship between the preset directions and the preset angle intervals may be the respective preset directions and corresponding angle intervals described in the above examples.

[0058] In another embodiment, the compass display method may be directly executed on the compass display device to prevent the compass from shaking in advance; or the compass display method may be executed after determining that the compass is shaking, without limitation.

[0059] Exemplarily, if it is determined based on the association between the preset directions and the preset angle interval that the compass repeatedly points to any two preset directions a preset number of times within a preset time period, the step of determining the first direction that the compass pointed to at the last moment is executed.

[0060] It is understandable that before the compass display method is executed, if it is determined that the compass repeatedly points to any two preset directions for a preset number of times within a preset time period, it indicates that the compass is shaking. Therefore, in order to avoid compass shaking, the compass display device can execute the above steps S101-S104; otherwise, the vehicle can still determine the direction of the compass based on the association between the preset direction and the preset angle interval.

[0061] The preset time period and the preset number of times can be set according to actual conditions and are not limited thereto. When jitter occurs, the compass usually points to two adjacent directions for multiple times in a row. That is, the two preset directions are usually two adjacent directions.
