Map Level Indication Method, Map Level Obtaining Method, and Related Product
A map level indication method, a map level obtaining method, and a related product include that a server determines, based on a control parameter corresponding to a target vehicle, a first map level corresponding to the target vehicle; and the server sends a first message to a target in-vehicle system of the target vehicle, where the first message indicates the first map level.
1 . A map level indication method implemented by a server, wherein the map level indication method comprises:
determining, based on a control parameter corresponding to a target vehicle, a first map level corresponding to the target vehicle; and
sending, to a target in-vehicle system of the target vehicle, a first message indicating the first map level.
2 . The map level indication method of claim 1 , further comprising determining, based on a preset mapping relationship, the first map level, wherein the preset mapping relationship comprises a correspondence between the first map level and the control parameter.
3 . The map level indication method of claim 1 , wherein the control parameter comprises one or more of a vehicle speed range, a vehicle acceleration range, a vehicle deceleration range, a vehicle autonomous driving level, or a category of a geographical environment in which the target vehicle is located.
4 . The map level indication method of claim 1 , wherein before determining the first map level, the map level indication method further comprises obtaining, based on a traveling status of the target vehicle, the control parameter.
5 . The map level indication method of claim 1 , wherein before determining the first map level, the map level indication method further comprises:
receiving a first traveling status of the target vehicle from a roadside unit (RSU) or a second traveling status of the target vehicle from the target in-vehicle system; and
obtaining, based on the first traveling status or the second traveling status, the control parameter.
6 . The map level indication method of claim 5 , further comprising:
receiving a third traveling status of a first vehicle from at least one first in-vehicle system other than the target in-vehicle system; and
further obtaining, based on the third traveling status, the control parameter.
7 . The map level indication method of claim 1 , wherein the first message instructs the target in-vehicle system to perform a control operation corresponding to the first map level, and wherein the control operation comprises:
using map data at a map precision level corresponding to the first map level; or
controlling traveling of the target vehicle based on a mapping relationship between the first map level and a traveling parameter, wherein the traveling parameter comprises one or more of a vehicle speed range, a vehicle acceleration range, a vehicle deceleration range, a vehicle autonomous driving level, or a vehicle hardware configuration level.
8 . The map level indication method of claim 7 , further comprising providing, to the target in-vehicle system, the map data.
9 . The map level indication method of claim 1 , wherein before determining the first map level, the map level indication method further comprises receiving, from the target in-vehicle system, a request message requesting the server to indicate a map level.
10 . A map level indication apparatus comprising:
a memory configured to store instructions; and
a processor coupled to the memory, wherein when executed by the processor, the instructions cause the map level indication apparatus to:
determine, based on a control parameter corresponding to a target vehicle, a first map level corresponding to the target vehicle; and
send, to a target in-vehicle system of the target vehicle, a first message indicating the first map level.
11 . The map level indication apparatus of claim 10 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to further determine, based on a preset mapping relationship, the first map level, and wherein the preset mapping relationship comprises a correspondence between the first map level and the control parameter.
12 . The map level indication apparatus of claim 10 , wherein the control parameter comprises one or more of a vehicle speed range, a vehicle acceleration range, a vehicle deceleration range, a vehicle autonomous driving level, or a category of a geographical environment in which the target vehicle is located.
13 . The map level indication apparatus of claim 10 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to obtain, based on a traveling status of the target vehicle, the control parameter.
14 . The map level indication apparatus of claim 10 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to:
receive, a first traveling status of the target vehicle from a roadside unit (RSU) or a second traveling status of the target vehicle from the target in-vehicle system; and
obtain, based on the first traveling status or the second traveling status, the control parameter.
15 . The map level indication apparatus of claim 14 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to:
receive, a third traveling status of a first vehicle from at least one first in-vehicle system other than the target in-vehicle system; and
further obtain, based on the third traveling status, the control parameter.
16 . The map level indication apparatus of claim 10 , wherein the first message instructs the target in-vehicle system to perform a control operation corresponding to the first map level, wherein the control operation comprises:
using map data at a map precision level corresponding to the first map level; or
controlling traveling of the target vehicle based on a mapping relationship between the first map level and a traveling parameter, wherein the traveling parameter comprises one or more of a vehicle speed range, a vehicle acceleration range, a vehicle deceleration range, a vehicle autonomous driving level, or a vehicle hardware configuration level.
17 . The map level indication apparatus of claim 16 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to provide the map data to the target in-vehicle system.
18 . The map level indication apparatus of claim 10 , wherein when executed by the processor, the instructions further cause the map level indication apparatus to receive, from the target in-vehicle system, a request message requesting the map level indication apparatus to indicate a map level.
19 . A map level obtaining apparatus comprising:
a memory configured to store instructions; and
a processor coupled to the memory, wherein when executed by the processor, the instructions cause the map level obtaining apparatus to:
receive, from a server, a first message indicating a first map level, wherein the first map level is based on a control parameter corresponding to a target vehicle to which the map level obtaining apparatus belongs; and
perform a control operation corresponding to the first map level.
20 . The map level obtaining apparatus of claim 19 , wherein when executed by the processor, the instructions further cause the map level obtaining apparatus to:
