[0014] The vehicle 102 is provided with a storage module 104 , and the storage module 104 is used to locally store initial map data.
[0015] The above-mentioned vehicle may refer to a work vehicle that requires map updating, and may be a vehicle traveling in an area where map data requires frequent updating, such as a truck traveling in an industrial park, a truck trailer traveling in a logistics center, an excavator, a bulldozer, or other vehicles traveling in a construction site. Alternatively, when a storage module on the vehicle for storing map data clears the map data after initialization, or when the vehicle travels to an area where corresponding map data is not stored in the storage module, the vehicle may also be determined to be the above-mentioned vehicle that requires map updating.
[0016] The above-mentioned initial map data may refer to map data obtained by collecting regional parameters of the area where the vehicle is currently located, which can be used to construct a map of the area where the vehicle is currently located, and may include but is not limited to: longitude and latitude, terrain, object equipment, equipment type, size, etc. of different locations in the area where the vehicle is currently located.
[0017] In this embodiment, the map updating system may include at least a vehicle that currently needs to perform a map update, and the vehicle may also be provided with a storage module for storing map data, such as the above-mentioned initial map data.
[0018] The cloud platform 106 is used to generate target map data and a download address of the target map data based on the initial map data, send the target map data to the shared storage module 108 , and send the download address of the target map data to the front-end 110 .
[0019] In this embodiment, a cloud platform that is in communication with the vehicle may also be provided in the map update system. The cloud platform may be used to receive initial map data sent from the vehicle, and process the initial map data to generate target map data to ensure the accuracy of the generated target map data, and at the same time generate a download address corresponding to the target map data so that other devices or users can obtain the target map data according to the download address. In addition, the cloud platform may also send the target map data to the shared storage module for storage, and send the download address of the target map data to the front-end processor.
[0020] The shared storage module 108 is connected to the cloud platform 106 and is used to receive and store target map data.
[0021] In this embodiment, as shown above, a shared storage module connected to the cloud platform may also be provided in the map updating system to receive and store the target map data sent by the cloud platform.
[0022] The front-end processor 110 is in communication with the cloud platform 106 and the vehicle 102 , and is used to transmit the initial map data to the cloud platform 106 , receive the download address, and transmit the download address to the vehicle 102 ;
[0023] In this embodiment, as shown above, a front-end processor that is communicatively connected to the cloud platform and the vehicle can also be set in the map update system. The front-end processor can transmit the initial map data on the vehicle to the cloud platform, and can also receive the download address sent by the cloud platform and transmit the download address to the above-mentioned vehicle.
[0024] The vehicle 102 is connected to the shared storage module 108 in communication, and is used to obtain the target map data from the shared storage module according to the download address, and transmit the target map data to the storage module.
[0025] In this embodiment, the above-mentioned vehicle can also be communicatively connected with the above-mentioned shared storage module. When the vehicle receives the download address transmitted by the front-end machine, it can download the target map data from the above-mentioned shared storage module according to the download address and store the target map data in the storage module on the vehicle.
[0026] In an embodiment of the utility model, a vehicle map update system including a vehicle, a cloud platform, a shared storage module, a cloud platform and a front-end machine is adopted. By utilizing the vehicle itself to collect map data of a specified area, initial map data with higher timeliness is obtained, and there is no need to perform excessive verification on the initial map data, thereby improving the efficiency of generating target map data and the corresponding download address, and storing the target map data in the shared storage module, and the vehicle downloads the corresponding target map data from the shared storage module according to the download address as required, which can reduce the limitation that the vehicle can only passively obtain the target map data, thereby ensuring the real-time performance of the target map data obtained by the vehicle as required, and further solving the technical problem of poor real-time performance of updating the map data on the vehicle in the related technology.
[0027] Furthermore, the vehicle is also equipped with: a map acquisition device for acquiring initial map data of the area where the vehicle is currently located.
[0028] In this embodiment, in order to facilitate the collection of regional parameters of the area where the vehicle is currently located, the above-mentioned map collection device can be configured on the vehicle. When the vehicle travels to an area where the corresponding map data is not stored in the storage module, the map collection device can be used to collect map data for the area where the vehicle is currently located to obtain the above-mentioned initial map data.
[0029] Furthermore, the map collection device includes: a positioning device for determining the current area of the vehicle; and a map collection device for collecting initial map data when the current area is a designated area.
[0030] The designated area may refer to the aforementioned area in which no corresponding map data is stored in the storage module.
[0031] In this embodiment, in order to improve the accuracy of the collected initial map data, the above-mentioned positioning device and map collection device can be configured in the map collection device. The positioning device can be used to determine the current area where the vehicle is located, and the map collection device can be used to collect the initial map data corresponding to the current area where the vehicle is located. The map update system can determine whether the vehicle is currently in a designated area through the above-mentioned positioning device, and when the vehicle is in the designated area, collect the initial map data of the designated area through the above-mentioned map collection device.
[0032] Furthermore, the initial map data includes version information corresponding to the initial map data.
[0033] In this embodiment, considering that the regional parameters of the area will change, the initial map data of the corresponding area will also change. Therefore, in order to avoid using erroneous initial map data to generate target map data of a specified area, corresponding version information can be set in the collected initial map data, such as collection time period, version number, collection vehicle and other information. The map update system can transmit the corresponding initial map data to the cloud platform for processing through the version information.
[0034] Furthermore, the cloud platform includes: a map generation module, which is used to generate target map data when the version information of the initial map data is not the latest version.
[0035] In this embodiment, the cloud platform may include a map generation module. The map update system may match the version information of the received initial map data with the version information of the previously received initial map data in the map generation module. If the matching result shows that the version information of the currently received initial map data is not the latest version, it means that the current map data of the specified area has not been received in the cloud platform. At this time, the cloud platform may generate target map data based on the currently received initial map data through the map generation module; if the matching result shows that the above version information is not the latest version, it means that the current map data of the specified area has been received in the cloud platform. At this time, the cloud platform may obtain target map data matching the initial map data based on the historical record of generating map data.
[0036] Furthermore, the initial map data includes an area identifier of an area where the vehicle is currently located.
[0037] In this embodiment, considering that the regional parameters of different areas are different, the corresponding initial map data collected are also different. Therefore, in order to avoid transmitting erroneous initial map data, when the regional parameters of the specified area are collected and the corresponding initial map data are obtained, the corresponding area identifier can also be set in the collected initial map data.
[0038] Furthermore, the cloud platform includes: a map generation module, which is used to generate target map data of the area corresponding to the area identifier.
[0039] In this embodiment, the map generation module configured in the cloud platform can also generate target map data corresponding to the initial map data according to the area identifier in the initial map data, so as to improve the accuracy when generating the download address and sending the target map data.
[0040] Furthermore, the storage module includes a first storage submodule and a second storage submodule, the first storage submodule is used to store initial map data, and the second storage submodule is used to store target map data.
[0041] In this embodiment, in order to avoid confusion between the collected initial map data and the received target map data, a first storage submodule and a second storage submodule may be configured in a storage module on the vehicle, and the first storage submodule may be used to store the initial map data, and the second storage submodule may be used to store the target map data.
[0042] Furthermore, the first storage submodule is used to automatically delete the initial map data after storing the initial map data for a specified time period.
[0043] In this embodiment, in order to reduce resource consumption, the map updating system may detect the storage duration of the initial map data in the first storage submodule, and automatically delete the initial map data after the storage duration reaches a specified duration.
[0044] Furthermore, the map acquisition device is also used to acquire initial map data when the current scene is a designated scene.
[0045] The above-mentioned specified scenario may refer to a scenario where target map data corresponding to a specified area is currently needed, for example, when a user needs to view a location within a specified area, or the vehicle's current route will pass through a specified area, or the map data of the area through which the vehicle passes needs to be updated frequently.
[0046] In this embodiment, when the scene when the vehicle currently drives into the designated area is the above-mentioned designated scene, the map updating system can use the above-mentioned map collection device to collect the above-mentioned initial map data.
[0047] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
