1. An apparatus for recognizing a special road condition, applied to a terminal device, and comprising:
at least one processor; and
at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
obtain map data at a current moment, wherein the map data comprises a first road area at the current moment, the special road condition is located in the first road area, the first road area is obtained by a server based on a road condition model and a vehicle parameter within a preset time period before the current moment, and the road condition model represents a correspondence between a feature of the vehicle parameter and the special road condition;
determine, based on a planned route of a vehicle, that a second road area exists in the planned route of the vehicle, wherein the second road area is in the first road area; and
generate a driving instruction based on description information about the special road condition, wherein the driving instruction indicates a driving behavior of the vehicle, wherein the driving behavior indicated by the driving instruction is same as a driving behavior indicated by a feature of a historical vehicle parameter used to obtain a target road condition model, and the target road condition model is a model for determining that the second road area comprises the special road condition.
 
10. An apparatus for recognizing a special road condition, applied to a server, and comprising:
at least one processor; and
at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
obtain a first road area at a current moment based on a road condition model and a vehicle parameter within a preset time period before the current moment, wherein the special road condition is located in the first road area, and the road condition model represents a correspondence between a feature of the vehicle parameter and the special road condition; and
mark the first road area on map data to obtain map data at the current moment, wherein a driving instruction is generated based on description information about the special road condition, wherein a driving behavior indicated by the driving instruction is same as a driving behavior indicated by a feature of a historical vehicle parameter used to obtain a target road condition model, and the target road condition model is a model for determining that a second road area in the first road area comprises the special road condition.
