Abstract

A method, system and medium for assisted driving of a vehicle are disclosed. The method comprises predicting a target intersection based on map information, a positioning location of the vehicle, and a motion status of the vehicle, where the target intersection is an intersection that the vehicle is to first pass in the future; determining a distance between the vehicle and the target intersection based on the map information and the positioning location of the vehicle; collect a turn light status of the vehicle; and when the distance between the vehicle and the target intersection is less than a first threshold, generating prompt information based on the turn light status of the vehicle and a first turning rule of a first lane in which the vehicle is located at the target intersection, where the prompt information prompts that the turn light status does not conform to the first turning rule.

First claim

What is claimed is:

1. A apparatus for assisted driving of a vehicle, comprising:
at least one processor; and
at least one memory storing program instructions and coupled to the at least one processor, wherein the program instructions, when executed by the at least one processor, cause the apparatus to:
predict a target intersection based on map information, a positioning location of the vehicle, and a motion status of the vehicle, wherein the target intersection is an intersection that the vehicle is to first pass in the future;
determine a distance between the vehicle and the target intersection based on the map information and the positioning location of the vehicle; and
generate prompt information based on a turn light status of the vehicle and a first turning rule of a first lane in which the vehicle is located at the target intersection, when the distance between the vehicle and the target intersection is less than a first threshold, wherein the prompt information prompts that the turn light status does not conform to the first turning rule.

2. The apparatus according to claim 1 , wherein when the distance between the vehicle and the target intersection is less than the first threshold and greater than a second threshold, the prompt information prompts the vehicle to change from the first lane to a second lane, wherein the turn light status meets a second turning rule of the second lane at the target intersection, and wherein the second threshold is less than the first threshold.

3. The apparatus according to claim 2 , wherein
when the distance between the vehicle and the target intersection is less than the second threshold, the prompt information prompts that the vehicle passes the target intersection from the first lane based on the first turning rule, wherein the second threshold is less than the first threshold.

4. The apparatus according to claim 3 , wherein the first threshold is related to at least one of a solid line length of the first lane, a running speed of the vehicle, or a traffic congestion degree near the positioning location of the vehicle.

5. The apparatus according to claim 4 , wherein the second threshold is related to at least one of the solid line length of the first lane, the running speed of the vehicle, or the traffic congestion degree near the positioning location of the vehicle.

6. The apparatus according to claim 1 , wherein the program instructions further cause the apparatus to:
report first information to a server recording the first lane at the target intersection as a turning violation-prone lane.

7. The apparatus according to claim 6 , wherein the first information comprises at least one of a first identifier of the vehicle or first identity information of a current driver of the vehicle.

8. The apparatus according to claim 1 , wherein the program instructions further cause the apparatus to:
store first information recording the first lane at the target intersection as a turning violation-prone lane.

9. The apparatus according to claim 8 , wherein the first information comprises at least one of a first identifier of the vehicle or first identity information of a current driver of the vehicle.

10. The apparatus according to claim 1 , wherein the map information is from a map, which further comprises first information, wherein the first information records at least one lane of at least one target intersection as a turning violation-prone lane.

11. The apparatus according to claim 10 , wherein the first information is information customized for one user, or information common to a plurality of users.

12. The apparatus according to claim 11 , wherein the first information comprises an identifier of the one user or identifiers of the plurality of users, and the identifier of the one user or the identifiers of the plurality of users comprise at least one of an identifier of a vehicle or identity information of a driver of the vehicle.

13. A apparatus for assisted driving of a vehicle, comprising:
at least one processor; and
at least one memory, wherein the at least one memory stores program instructions and coupled to the at least one processor, wherein the program instructions, when executed by the at least one processor, cause apparatus to:
determine, based on a driving path planning result, that a vehicle is to pass a target intersection in a first direction;
determine, based on a map, a first lane in which the vehicle passes the target intersection in the first direction, wherein the map records at least one lane of at least one target intersection as a turning violation-prone lane, and the first lane is one of at least one turning violation-prone lane recorded in first information on the map; and
generate reminder information, wherein the reminder information reminds a driver that the first lane in which the vehicle is to pass in the future based on a planned driving route is a turning violation-prone lane.

14. The apparatus according to claim 13 , wherein the first information further comprises identity information of a historical user that has a turning violation risk when the vehicle passes the target intersection from the first lane, and the identity information of the historical user comprises at least one of an identifier of the vehicle or identity information of the driver of the vehicle;
wherein the program instructions further cause the apparatus to:
obtain identity information of a current user, wherein the identity information of the current user comprises at least one of the identifier of the vehicle or identity information of a current driver of the vehicle; and
generate the reminder information based on a result of consistency comparison between the identity information of the current user and the identity information of the historical user.

15. A method of assisted driving of a vehicle, comprising:
predicting a target intersection based on map information, a positioning location of the vehicle, and a motion status of the vehicle, wherein the target intersection is an intersection that the vehicle is to first pass in the future;
determining a distance between the vehicle and the target intersection based on the map information and the positioning location of the vehicle; and
generating prompt information based on a turn light status of the vehicle and a first turning rule of a first lane in which the vehicle is located at the target intersection, when the distance between the vehicle and the target intersection is less than a first threshold, wherein the prompt information prompts that the turn light status does not conform to the first turning rule.

16. The apparatus according to claim 15 , wherein when the distance between the vehicle and the target intersection is less than the first threshold and greater than a second threshold, the prompt information prompts the vehicle to change from the first lane to a second lane, wherein the turn light status meets a second turning rule of the second lane at the target intersection, and wherein the second threshold is less than the first threshold.

17. The method according to claim 16 , wherein
when the distance between the vehicle and the target intersection is less than the second threshold, the prompt information prompts that the vehicle passes the target intersection from the first lane based on the first turning rule, wherein the second threshold is less than the first threshold.

18. The method according to claim 16 , wherein the first threshold is related to at least one of a solid line length of the first lane, a running speed of the veh
