Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Referring to fig. 1 and fig. 2, a driving prompting method according to an embodiment of the present invention is applied to a vehicle 10, and the driving prompting method includes:

01: acquiring a distance D formed between a plurality of obstacles 20 on a passing route;

02: and determining prompt information according to the distance D for prompting.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to FIG. 3, the vehicle 10 includes a memory 11 and a processor 12. The memory 11 stores therein a computer-executable program. The processor 12 is configured to: acquiring a distance D formed between a plurality of obstacles 20 on a passing route; and determining prompt information according to the distance D for prompting.

In the driving prompting method and the vehicle 10, the distance D between the obstacles 20 is determined, and the distance degree between the obstacles 20 is prompted to the driver, so that the driver can easily judge whether the width of the road ahead allows the vehicle to pass, an experienced driving mode is avoided, and the passing efficiency is improved.

Specifically, in fig. 2, the obstacle 20 is another vehicle. The number of obstacles 20 is two, and the two obstacles 20 are spaced apart from each other by a distance D and are close to the passing route of the vehicle 10, so that the obstacles 20 may block the vehicle 10 from traveling along the passing route. When the vehicle 10 runs, the distance D formed by the interval between the two obstacles 20 can be acquired, and the corresponding prompt information is determined according to the size of the distance D, so as to give a prompt information to the driver for prompting. The driver, upon confirming the prompting message, may then determine whether the separation D between the two obstacles 20 is sufficient to allow the vehicle 10 to pass through the space between the two obstacles 20.

Regarding the passing route, please refer to fig. 2, the passing route may be determined for the vehicle 10 according to the road information of the current road segment. The road surface information may include traffic lines of the road surface, traffic signs around the road section. The road information may be acquired by a vision sensor, a depth-of-field radar, or the like, or may be determined by navigation by a navigation system.

Regarding the distance D, please refer to fig. 2, in the case of determining the passing route, it is able to detect whether there is an obstacle 20 along the road surface where the passing route is located, and when it is detected that there is an obstacle 20 on the road surface, determine the corresponding distance D according to the interval between the obstacles 20.

With respect to obtaining the distance D, in some embodiments, the vehicle 10 may include a depth radar that may obtain road surface information along the transit route, and through analysis of the road surface information, it may be determined whether the obstacle 20 is present on the road surface along the transit route, and the distribution of the obstacle 20 on the road surface may be determined. According to the distribution of the obstacles 20 on the road surface, the size of the interval between the obstacles 20 can be determined, the interval D formed by the interval is obtained, whether the vehicle 10 is suitable for passing through the interval between the obstacles 20 is judged, and prompt information is generated according to the judgment result to prompt a driver.

In addition, in a scene where the number of the obstacles 20 is one, it can be understood that the passing route mostly corresponds to the extending direction of the current road section, and since both sides of the current road section have edges, the maximum width of the current road section is formed, in some embodiments, when other objects (such as pedestrians, other vehicles, roadblocks, etc.) are blocked on the road surface of the current road section, the distance D may be obtained by combining the other objects and the edges of both sides of the current road section, the size of the distance D formed between the other objects and the edges of both sides of the current road section is determined, and the driver is prompted according to the determined prompt information, whether the distance between the other objects and the edges of both sides of the current road section is suitable for the vehicle 10 to continue to pass. The edges of the two sides of the current road section can be acquired through a vision sensor, a depth-of-field radar and the like, and can also be determined through navigation of a navigation system.

In a scenario where the number of the obstacles 20 is two or more, the corresponding distances D may be acquired for the intervals between two of the obstacles 20, respectively, so that the acquired distances D are plural in number. In this case, one of the plurality of distances D may be used as the distance D for determining the prompt information, and one of the distances D may be the smallest one of the plurality of distances D. When the distance D is determined to be insufficient for the vehicle 10 to pass, it can be determined that the obstacle 20 on the passing route has caused a blockage to the vehicle 10, and the vehicle 10 cannot continue to travel along the passing route. In the above situation, in one embodiment, a prompt message may be sent to the driver to inform the driver that the road ahead is not available, so that the driver does not continue to move forward due to a wrong judgment, and potential safety hazards such as collision are avoided.

Referring to fig. 4, the hint information includes first light bar information 131 and second light bar information 132. The first light stripe information 131 corresponds to the vehicle 10, and the second light stripe information 132 corresponds to the plurality of obstacles 20.

Referring to fig. 2 and 5, in some embodiments, step 02 (determining a prompt message for prompting according to the distance D) includes:

021: displaying the first light bar information 131 at a first length corresponding to a transit width W of the vehicle 10 along the transit route;

022: the second light bar information 132 is displayed with a second length, the second length corresponds to the distance D, and the display length direction of the first light bar information 131 and the display length direction of the second light bar information 132 are substantially the same.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: displaying the first light bar information 131 at a first length corresponding to a transit width W of the vehicle 10 along the transit route; the second light bar information 132 is displayed with a second length, the second length corresponds to the distance D, and the display length direction of the first light bar information 131 and the display length direction of the second light bar information 132 are substantially the same.

In this way, the magnitude relationship between the pitch D and the passage width W can be intuitively demonstrated.

Specifically, in fig. 4, the vehicle 10 may include a light emitting device 13. The light emitting device 13 is arranged in a long shape, and can emit light in a display length direction formed by the long structure and display information of light bars.

In one embodiment, the vehicle 10 may display the first light bar information 131 through the light emitting device 13, and a length of the first light bar information 131 in a display length direction of the light emitting device 13 is a first length. When the distance D formed by the obstacle 20 is acquired, the vehicle 10 displays the second light bar information 132 by the light-emitting device 13, and the length of the second light bar information 132 in the display length direction of the light-emitting device 13 is the second length.

On the basis of the above, the first length corresponds to the passing width W of the vehicle 10 along the passing route, and the second length corresponds to the distance D, and the driver can determine the size relationship between the passing width W and the distance D according to the length relationship between the first light bar information 131 and the second light bar information 132 displayed by the light-emitting device 13, so as to determine whether the vehicle 10 can pass through the distance D. Moreover, the first light bar information 131 and the second light bar information 132 are both displayed along the display length direction of the light emitting device 13, so that the display length direction of the first light bar information 131 and the display length direction of the second light bar information 132 are substantially the same, facilitating the driver to easily compare the length relationship between the first length and the second length.

In fig. 4, the light emitting device 13 is provided at the front end of the cab in the vehicle 10, so that the driver can easily observe the information on the light bar emitted from the light emitting device 13 when recognizing the road condition ahead of the vehicle 10, and can easily confirm the presentation information.

In some embodiments, step 022 (displaying the second light bar information 132 at the second length) comprises:

the second light bar information 132 is displayed at least partially overlaid on the first light bar information 131.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: the second light bar information 132 is displayed at least partially overlaid on the first light bar information 131.

Thus, the visual effect of comparing the first length with the second length is improved.

Specifically, in fig. 2 and 4, when the distance D is acquired, the light-emitting device 13 may determine the second length of the second light bar information 132 after displaying the first light bar information 131 with the first length, and overlay-display the second light bar information 132 on the first light bar information 131 along the display length direction on the light-emitting device 13, so that the driver does not need to observe the first light bar information 131 and the second light bar information 132 as a whole and then compare them, but may observe that the second light bar information 132 is overlayed with the upper first light bar information 131 and then confirm the lengths of the remaining displayed first light bar information 131. It is understood that if the distance D is smaller than the passing width W, the remaining display length of the first light bar information 131 is larger, which means that the distance D is narrower and the vehicle 10 cannot pass through; if the distance D is larger than the passing width W, the remaining display length of the first light bar information 131 is smaller so as to be completely covered by the second light bar information 132, which indicates that the distance D is wider to allow the vehicle 10 to pass through.

Referring to fig. 2 and 4, in some embodiments, the first length is a predetermined length, and a ratio between the first length and the second length is equal to a ratio between the traffic width W and the distance D. In fig. 4, the light emitting devices 13 are arranged in a layout extending from the driver's seat to the passenger's seat, and when the light emitting devices 13 display the first light bar information 131, the light emitting devices 13 all display the first light bar information 131, and when the light emitting devices 13 display the second light bar information 132, the light emitting devices 13 display the second light bar information 132 according to the actual length of the pitch D. Since the passing width W of the vehicle 10 often corresponds to the width of the vehicle body of the vehicle 10, the first light bar information 131 is displayed in a preset length, so that the driver does not need to confirm the display length of the first light bar information 131, and relative to the size of the distance D which is easy to change, the driver can remember the width of the vehicle body of the vehicle 10 more easily, observe the proportion of the second length relative to the first length more intuitively, and do not need to visually confirm the size of the interval between the obstacles 20.

Referring to fig. 4, the first light bar information 131 and the second light bar information 132 are respectively displayed in different colors.

As such, the first and second

light bar information

131, 132 may be conveniently identified. In one embodiment, the first light bar information 131 is displayed in red and the second light bar information 132 is displayed in purple.

Referring to fig. 6, the prompt message includes first image information 141 and second image information 146, the first image information 141 corresponds to the vehicle 10, and the second image information 146 corresponds to the plurality of obstacles 20.

Referring to fig. 2 and 7, in some embodiments, step 02 (determining a prompt message for prompting according to the distance D) includes:

024: displaying first image information 141, wherein the first image information 141 comprises predicted traffic information 142, and the predicted traffic information 142 is used for displaying a predicted area 143 where the vehicle 10 runs along a traffic route;

026: the second image information 146 is displayed, and the second image information 146 corresponds to the display distance D.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: displaying first image information 141, wherein the first image information 141 comprises predicted traffic information 142, and the predicted traffic information 142 is used for displaying a predicted area 143 where the vehicle 10 runs along a traffic route; the second image information 146 is displayed, and the second image information 146 corresponds to the display distance D.

Specifically, in fig. 6, the vehicle 10 may include a display device 14, and the display device 14 may display image information. The display device 14 displays the first image information 141, so that the driver can determine the estimated area 143 by aiming at the display device 14 positioned below the front window, and the track of the expected passing of the vehicle 10 is conveniently judged. When the vehicle 10 encounters the obstacle 20, the display device 14 may further display the second image information 146, and the driver may determine the relationship between the passing width W and the distance D based on the first image information 141 and the second image information 146 simultaneously displayed on the display device 14, and may intuitively determine whether the vehicle 10 can pass through the distance D.

In fig. 6, the display device 14 is disposed below the front window so that the driver can easily observe the image information emitted from the display device 14 when recognizing the road condition ahead of the vehicle 10, thereby easily confirming the presentation information. In the case where the traffic width W of the vehicle 10 is greater than the formed distance D, a "cautious traffic" field and corresponding warning icon may also be displayed by the display device 14.

In addition, in fig. 6, the first image information 141 may further include vehicle position information 145, and the vehicle position information 145 may display the position of the front of the vehicle 10, so that the intuitive effect of the relative position between the vehicle 10 and the distance D may be improved.

Referring to fig. 6 and 8, in some embodiments, step 024 (displaying the first image information 141) includes:

025: displaying the estimated width line 144, wherein the length of the estimated width line 144 corresponds to the passing width W of the vehicle 10 along the passing route;

step 026 (displaying second image information 146), comprising:

027: the second image information 146 is displayed along the estimated width line 144 in an overlaid manner, and the display length of the second image information 146 corresponds to the distance D.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: the second image information 146 is displayed along the estimated width line 144 in an overlaid manner, and the display length of the second image information 146 corresponds to the distance D.

Therefore, the visual effect of identifying the image information can be improved.

Specifically, in fig. 6, the driver can determine the area to be swept by the vehicle 10 while passing along the passing route by confirming the estimated area 143. The length of the estimated width line 144 corresponds to the passing width W of the vehicle 10, and the position where the vehicle head can reach when the vehicle 10 passes through the estimated area 143 can be determined according to the position of the estimated width line 144. In the case where the pitch D is acquired, the second image information 146 is displayed overlaid on the estimated width line 144, so that the position of the pitch D corresponding to the estimated region 143 can be determined.

On the basis, the estimated length of the width line 144 corresponds to the passing width W of the vehicle 10, and the display length of the second image information 146 corresponds to the length of the distance D, so that the driver can judge the length relationship between the passing width W and the distance D according to the estimated length relationship between the width line 144 and the second image information 146, and further can judge whether the vehicle 10 can pass through the interval corresponding to the distance D when the vehicle 10 continues to run along the passing route, thereby achieving an intuitive effect.

Referring to fig. 6, the second image information 146 includes a plurality of obstacle position information 147 and a plurality of distance information 148, where the number of the obstacle position information 147 is plural.

Referring to fig. 9, in some embodiments, step 027 (displaying second image information 146 overlaid along estimated width line 144) includes:

028: displaying a plurality of obstacle position information 147 along the estimated width line 144, wherein each obstacle position information 147 corresponds to the position of one obstacle 20 relative to the vehicle 10 on the passing route;

029: the distance information 148 is displayed along the estimated width line 144, two corresponding obstacle position information 147 is displayed at two ends of the distance information 148 along the length direction of the second image information 146, and the distance information 148 corresponds to the distance D between the two obstacles 20.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: displaying a plurality of obstacle position information 147 along the estimated width line 144, wherein each obstacle position information 147 corresponds to the position of one obstacle 20 relative to the vehicle 10 on the passing route; the distance information 148 is displayed along the estimated width line 144, two corresponding obstacle position information 147 is displayed at two ends of the distance information 148 along the length direction of the second image information 146, and the distance information 148 corresponds to the distance D between the two obstacles 20.

In this manner, the driver may be facilitated to judge the traffic strategy of the vehicle 10.

Specifically, the plurality of obstacle position information 147 corresponds to the plurality of obstacles 20 one-to-one, and the obstacle position information 147 may indicate the position of the corresponding obstacle 20 relative to the vehicle 10 along the transit route. In the figure, the number of the obstacles 20 is two, wherein one obstacle 20 is located on the left side with respect to the vehicle 10 and the other obstacle 20 is located on the right side with respect to the vehicle 10, so that the interval between the two obstacles 20 forms the distance D.

When the second image information 146 is displayed on the display device 14, the obstacle position information 147 and the distance information 148 are correspondingly displayed. The number of the obstacle position information 147 is two, one obstacle position information 147 corresponds to the left obstacle 20, the other obstacle position information 147 corresponds to the right obstacle 20, and the distance information 148 extends from the position of one obstacle position information 147 to the position of the other obstacle position information 147, so that the distance information 148 correspondingly represents the distance D between the two obstacles 20.

On the basis, since the estimated area 143 is formed by extending along the passing route, the obstacle position information 147 and the distance information 148 are displayed on the estimated width line 144 in a covering manner, so that the driver can conveniently determine the position of the obstacle 20 relative to the vehicle 10 and the distance D between the obstacles 20, and can judge whether the distance between the obstacles 20 can pass the vehicle 10, when the vehicle 10 can pass, the driving direction of the vehicle 10 can be adjusted according to the position of the obstacle position information 147 and the distance information 148 on the estimated width line 144, and the situation that the vehicle 10 easily collides with the obstacle 20 when the distance D is small is avoided.

In addition, when the distance D is greater than the passing width W, the obstacle position information 147 is displayed on the extension of the estimated width line 144, so that the driver determines that the distance D between the obstacles 20 is available for the vehicle 10 to pass.

In some embodiments, the estimated traffic information 142, the spacing information 148, and the obstacle location information 147 are each displayed in a different color.

Therefore, different information can be conveniently identified. In one embodiment, the display color of the estimated traffic information 142 is orange, the display color of the obstacle position information 147 is purple, and the display color of the distance information 148 is green.

In some embodiments, the reminder information includes a voice announcement information. It can be understood that the prompt is provided for the driver in the form of voice broadcast, so that the driver can more easily pay attention to observing the change of the surrounding environment, and the driver can deal with the emergency situation.

Referring to fig. 9, in some embodiments, step 02 (determining a prompt message for prompting according to the distance D) includes:

031: determining distance condition information according to the distance D and the passing width W of the vehicle 10 along the passing route;

033: determining passing judgment information according to the distance condition information;

036: and generating voice information according to the distance condition information and the traffic judgment information so as to perform voice broadcasting on the voice information.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: determining distance condition information according to the distance D and the passing width W of the vehicle 10 along the passing route; determining passing judgment information according to the distance condition information; and generating voice information according to the distance condition information and the traffic judgment information so as to perform voice broadcasting on the voice information.

In this way, it is convenient for the driver to determine whether the vehicle 10 can pass through the interval corresponding to the distance D by voice.

Specifically, in some embodiments, in the case that the distance D is obtained, the distance D and the passing width W may be compared, and distance condition information is obtained according to a comparison result, so that the distance condition information may be used to represent a size relationship between the distance D and the passing width W. In the case of determining the distance condition information, the corresponding passage judgment information may be determined according to the size relationship between the distance D and the passage width W, and the voice information may be generated according to the distance condition information and the passage judgment information, and the driver may determine the size relationship between the distance D and the passage width W and whether the vehicle 10 can pass or not after hearing the voice information.

In some embodiments, referring to fig. 2 and 10, step 031 (determining the distance condition information according to the distance D and the traffic width W of the vehicle 10 along the traffic route) includes:

032: determining whether the difference between the distance D and the passing width W is less than or equal to a preset width distance;

step 033 (determining traffic judgment information according to the distance status information), includes:

034: determining that the vehicle 10 cannot pass through in the case where the difference between the distance D and the passing width W is less than or equal to the preset width distance;

035: in the case where the difference between the distance D and the passing width W is larger than the preset width distance, it is determined that the vehicle 10 can pass.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: determining whether the difference between the distance D and the passing width W is less than or equal to a preset width distance; determining that the vehicle 10 cannot pass through in the case where the difference between the distance D and the passing width W is less than or equal to the preset width distance; in the case where the difference between the distance D and the passing width W is larger than the preset width distance, it is determined that the vehicle 10 can pass.

Specifically, referring to fig. 2, in some embodiments, the corresponding different distance status information is determined by determining whether the difference between the distance D and the passing width W is less than or equal to the preset width distance. Wherein, the distance status information may include: the difference between the distance D and the passing width W is smaller than the preset width distance, the difference between the distance D and the passing width W is equal to the preset width distance, and the difference between the distance D and the passing width W is larger than the preset width distance. Under the condition that the difference between the distance D and the passing width W is smaller than or equal to the preset width distance, the situation that the interval corresponding to the distance D does not meet the passing condition of the vehicle 10 can be known, and therefore the situation that the vehicle 10 cannot pass is determined; in the case where it is determined that the difference between the distance D and the passing width W is greater than the preset width distance, it is possible to know that the interval corresponding to the distance D meets the condition for the vehicle 10 to pass through, and thus it is determined that the vehicle 10 can pass through. The preset distance D may be calibrated through actual testing.

On the basis, in one embodiment, the passing width W of the vehicle 10 is 2.5 meters, the size of the distance D is 2 meters, the preset width distance is 0.2 meters, the distance condition information indicates that the difference value between the distance D and the passing width W is smaller than the preset width distance, and the passing judgment information indicates that the vehicle 10 cannot pass, so that a voice segment of the 'too narrow distance' is generated according to the distance condition information, a voice segment of the 'vehicle 10 cannot pass' is generated according to the passing judgment information, and the voice information of the 'too narrow distance, the vehicle 10 cannot pass' can be obtained according to the generated voice segment, and the voice information is sent to the driver. In another embodiment, the passing width W of the vehicle 10 is 2.5 meters, the distance D is 3 meters, the preset width distance is 0.2 meters, the distance condition information indicates that the difference between the distance D and the passing width W is greater than the preset width distance, and the passing judgment information indicates that the vehicle 10 can pass, so that the voice segment of "wider distance" is generated according to the distance condition information and the voice segment of "the vehicle 10 can pass" is generated according to the passing judgment information, and the voice information of "wider distance and the vehicle 10 can pass" can be obtained according to the generated voice segment, and the voice information is sent to the driver.

In some embodiments, the hint information may include the first numerical information and the second numerical information. The first numerical information corresponds to the size of the passing width W of the vehicle 10 along the passing route, and the second numerical information corresponds to the size of the distance D.

Specifically, referring to fig. 6, after determining the prompt information according to the distance D to prompt, the vehicle 10 may display the first numerical information and the second numerical information, and the driver may determine the relationship between the size of the passing width W and the size of the distance D according to the displayed first numerical information and the displayed second numerical information, so as to determine whether the distance between the obstacles 20 corresponding to the distance D can be passed by the vehicle 10. In this manner, the magnitude relationship between the pitch D and the passage width W can be directly demonstrated.

In addition, in some embodiments, the first numerical information and the second numerical information may be prompted by voice, so that the driver may know the magnitude relationship between the distance D and the traffic width W without visual observation, and the driver may be prevented from observing the change of the surrounding environment more easily.

That is, referring to fig. 3, for the vehicle 10 according to the embodiment of the present invention, the processor 12 may be configured to display the first numerical information and the second numerical information, or may be configured to perform voice prompt on the first numerical information and the second numerical information.

In addition, in other embodiments, after determining the distance D formed between the obstacles 20 and the passing width W of the vehicle 10, the vehicle 10 may maintain the distance between the vehicle 10 and each obstacle 20 while the vehicle 10 travels along the passing route according to the position of the obstacle 20 relative to the vehicle 10 until the vehicle 10 passes through the interval between the obstacles 20, so that the vehicle 10 may automatically avoid the obstacles 20 while performing the automatic driving function.

Referring to fig. 11, in some embodiments, the pitches include a lateral pitch Dh and an actual pitch Da. The lateral distance Dh corresponds to the interval at which the plurality of obstacles 20 are formed in the direction perpendicular to the passing route, and the actual distance Da corresponds to the minimum interval between the plurality of obstacles 20. The prompt message comprises a first prompt message and a second prompt message. The first cue information corresponds to the lateral distance Dh and the second cue information corresponds to the actual distance Da.

Specifically, in fig. 11, after the passing route of the vehicle 10 is determined, the respective distances from the two obstacles 20 to the passing route may be determined, and the distance formed by the two obstacles 20 in the direction perpendicular to the passing route, that is, the lateral distance Dh may be determined according to the sum of the respective distances from the two obstacles 20 to the passing route, and the actual distance Da is the minimum distance formed by the direct interval between the two obstacles 20. In some embodiments, the lateral spacing Dh and the actual spacing Da may be determined by depth radar.

Referring to fig. 12, step 02 (determining a prompt message for prompting according to the distance) includes:

041: prompting first prompt information and second prompt information under the condition that the transverse distance Dh is smaller than the preset width and the actual distance Da is larger than the preset width;

042: and prompting the first prompt message or the second prompt message under the conditions that the transverse distance Dh and the actual distance Da are both larger than the preset width and the difference value between the transverse distance Dh and the actual distance Da is smaller than the preset difference value.

The travel presentation method according to the embodiment of the present invention can be realized by the vehicle 10 according to the embodiment of the present invention. Specifically, referring to fig. 3, the processor 12 is configured to: prompting first prompt information and second prompt information under the condition that the transverse distance Dh is smaller than the preset width and the actual distance Da is larger than the preset width; and prompting the first prompt message or the second prompt message under the conditions that the transverse distance Dh and the actual distance Da are both larger than the preset width and the difference value between the transverse distance Dh and the actual distance Da is smaller than the preset difference value.

Therefore, the passing efficiency of the self vehicle can be improved.

Specifically, in fig. 11, when the lateral distance Dh is smaller than the preset width and the actual distance Da is larger than the preset width, it may be determined that the vehicle 10 cannot continue the interval corresponding to the lateral distance Dh along the passing route, and the interval corresponding to the actual distance Da between the two obstacles 20 is likely to allow the vehicle 10 to pass, so as to prompt the driver with first prompt information corresponding to the lateral distance Dh and second prompt information corresponding to the actual distance Da, so that the driver can determine that the vehicle cannot currently travel along the passing route according to the first prompt information, and determine that the vehicle 10 can still pass through the space between the two obstacles 20 according to the second prompt information, so that the driver can turn according to the actual scene to adjust the traveling direction of the vehicle 10 until determining the angle at which the vehicle 10 can be driven, without waiting for the two obstacles 20 to be moved apart, the vehicle 10 is driven again to continue the passage. The predetermined width may be the passing width W of the vehicle 10, or may be another value greater than the passing width W.

When the transverse distance Dh and the actual distance Da are both larger than the preset width, and the difference between the transverse distance Dh and the actual distance Da is smaller than the preset difference, it can be determined that the difference between the transverse distance Dh and the actual distance Da is smaller, and the space formed between the two obstacles 20 is larger, so that the vehicle 10 can be allowed to pass, and thus one of the first prompt message and the second prompt message is prompted to the driver, the driver can determine the actual passing route according to the obtained prompt message, and the problem that the interference is easily caused due to excessive prompt messages is reduced.

By determining the transverse distance and the actual distance, it is possible to remotely determine whether the distance between the two obstacles 20 is accessible without acquiring a prompt by using a radar or other means after the vehicle 10 approaches, and thus, the method is applicable to a vehicle without an Advanced Driving Assistance System (ADAS) function, and is advantageous for reducing the cost.

In another embodiment, when the indication information is displayed in the form of light information, the first indication information and the second indication information may be displayed in different colors, so that the lateral distance and the actual distance may be visualized, and the driver may distinguish the lateral distance Dh and the actual distance Da by color.
