7. The method according to claim 6 , wherein the method further comprises:
in response to determining that a height of a current vehicle is less than the height threshold of the road, outputting first prompt information, wherein the first prompt information is used to indicate the current vehicle to drive normally; or
in response to determining that the height of the current vehicle is greater than the height threshold of the road, outputting second prompt information, wherein the second prompt information is used to indicate the current vehicle to stop driving.
8. An apparatus, comprising:
one or more processors, and one or more memories including computer-executable instructions that, when executed by the one or more processors, cause the apparatus to perform operations comprising:
determining a target object on a road; and

12. The apparatus according to claim 11 , wherein the operations further comprise:
determining the total width of the lanes as the total width of the road if the first positional relationship indicates that the support parts of the target object are disposed at positions of the lane lines on the two edge sides; or
determining the total width of the road based on the total width of the lanes and widths between the support parts of the target object and the lane lines on the two edge sides if the first positional relationship indicates that the support parts of the target object are disposed at positions outside the lane lines on the two edge sides.
13. The apparatus according to claim 12 , wherein the total width of the road is a sum of the total width of the lanes and the widths between the support parts of the target object and the lane lines on the two edge sides.
14. A non-transitory computer readable medium storing one or more programming instructions executable by one or more processors to cause the one or more processors to perform operations comprising:
determining a target object on a road; and
determining a height threshold of the road based on the target object, wherein the height threshold is used to indicate a maximum allowed height of the road, and wherein determining the height threshold of the road based on the target object comprises:
determining a total width of the road based on the target object and a total width of lanes of the road, wherein the total width of lanes is determined based on a quantity of the lanes and a width of each lane; and
determining the height threshold of the road based on the total width of the road and a spatial parameter, wherein the spatial parameter indicates a width-to-height ratio of road space.
15. The non-transitory computer readable medium according to claim 14 , wherein the target object comprises at least one of a height restriction barrier, an underbridge, a tunnel entrance, or a parking barrier.
