Abstract
Receiving a map update indication message from a map server; sending a first map update query request message to an OTA upgrade master node apparatus in a vehicle based on the map update indication message; receiving a first map update query feedback message that is fed back by the OTA upgrade master node apparatus based on the first map update query request message; sending a map data download start message to the map server in response to the first map update query feedback message; receiving map update data sent by the map server; and updating a map in the vehicle based on the map update data.
Claims11
A map update apparatus in a vehicle comprising:
- at least one processor and at least one memory, wherein the at least one memory is to store program instructions, and the at least one processor is coupled to the at least one memory to execute the instructions, which thereby causes the at least one processor to:
- receive a map update indication message from a map server, wherein the map update indication message indicates a map update task;
- send a first map update query request message to an over the air (OTA) upgrade master node apparatus in the vehicle based on the map update indication message, wherein the first map update query request message comprises related information of the map update task;
- receive a first map update query feedback message that is fed back by the OTA upgrade master node apparatus based on the first map update query request message, wherein the first map update query feedback message comprises at least one of status information or map update permission information of the vehicle;
- send a map data download start message to the map server, wherein the map data download start message is used to trigger the map server to send map update data to the map update apparatus;
- receive the map update data sent by the map server;
- and
- update a map in the vehicle based on the map update data.

A map update apparatus in a vehicle comprising:
- at least one processor and at least one memory, wherein the at least one memory stores program instructions, and the at least one processor is coupled to the at least one memory to execute the instructions, which thereby causes the at least one processor to:
- receive a map update notification message from an OTA upgrade master node apparatus in the vehicle;
- download map update data from a map server based on the map update notification message;
- send a map data download complete message to the OTA upgrade master node apparatus, wherein the map data download complete message indicates that the map update apparatus has completed downloading of the map update data;
- receive a map data update start message from the OTA upgrade master node apparatus;
- and
- update a map in the vehicle by using the downloaded map update data, in response to the map data update start message.
