Method for coordinating road users via a server device, and server device and a control circuit for carrying out the method

A server device, comprising:

• a processor configured to coordinate action instructions for executing actions, to motor vehicles and/or user devices in roles of a plurality of road users, the processor configured to by,
• repeatedly create, based on environment data from a plurality of data sources, including from the plurality of road users, corresponding to respective real environments, a digital central model that is a virtual representation of the respective real environments,
• calculate, based on the digital central model, instruction data respectively for action instructions for coordinated road users, from among the plurality of road users, such that
• an action instruction, from among the action instructions, defines an action, from among the actions, to be executed by a respective coordinated road user, from among the coordinated road users, in a real environment of the respective coordinated road user, from among the respective real environments, and
• the digital central model virtually describes a plurality of traffic objects, a traffic object, from among the plurality of traffic objects, assigned to an object category, from a plurality of object categories, and at least one stipulation, from among a plurality of stipulations, stipulated for the object category;
• transmit the action instructions to the coordinated road users;
• repeatedly provide the coordinated road users with the digital central model such that the coordinated road users generate and transmit to the server device, respective delta data of the coordinated road users based on a comparison of the digital central model with the respective real environments of the coordinated road users, the respective delta data describing a difference between the respective real environments of the coordinated road users and the digital central model;
• receive from the coordinated road users, the respective delta data;
• update the digital central model on basis of the respective delta data of the coordinated road users and using the digital central model updated to check whether the instruction data for at least one coordinated road user, from among the coordinated road users, is to be corrected in accordance with a correction criterion based on at least one stipulation stipulated for the object category, from among a plurality of stipulations including,
• a change frequency specifying a maximum rate at which the respective delta data of the coordinated road users is generated for the traffic object of the object category, and
• a priority stipulating an order with regard to determining the respective delta data of the coordinated road users, based on available computation time;
• and
• when the instruction data to be corrected is identified according to the correction criterion,
• update the instruction data by adapting the action instruction to the digital central model updated, and
• transmit, to the at least one coordinated road user, the instruction data of the action instruction updated for the at least one coordinated road user.

A control circuit for motor vehicles and/or user devices in roles of a plurality of road users, the control circuit configured for a road user, from among the plurality of road users, to,

• receive model data of a digital central model of an environment of the road user from a server device,
• the server device including a processor configured to coordinate action instructions for executing actions, to the plurality of road users, the processor configured to,

• calculate, based on the digital central model, instruction data respectively for action instructions for coordinated road users, from among the plurality of road users, such that
• an action instruction, from among the action instructions, defines an action, from among the actions, to be executed by a respective coordinated road user, from among the coordinated road users, in a real environment of the respective coordinated road user, from among the respective real environments, and
• the digital central model virtually describes a plurality of traffic objects, a traffic object, from among the plurality of traffic objects, assigned to an object category, from a plurality of object categories, and at least one stipulation, from among a plurality of stipulations, stipulated for the object category;
• transmit the action instruction to the road user as a coordinated road user among the coordinated road user;
• repeatedly provide the coordinated road users with the digital central model such that the coordinated road users generate and transmit to the server device, respective delta data of the coordinated road users based on a comparison of the digital central model with the respective real environments of the coordinated road users, the respective delta data describing a difference between the respective real environments of the coordinated road users and the digital central model;
• receive from the coordinated road users, the respective delta data;
• update the digital central model on basis of the respective delta data of the coordinated road users and using the digital central model updated to check whether the instruction data for at least one coordinated road user, from among the coordinated road users, is to be corrected in accordance with a correction criterion based on at least one stipulation stipulated for the object category, from among a plurality of stipulations including,
• a change frequency specifying a maximum rate at which the respective delta data of the coordinated road users is generated for the traffic object of the object category, and
• a priority stipulating an order with regard to determining the respective delta data of the coordinated road users, based on available computation time;
• and
• when the instruction data to be corrected is identified according to the correction criterion,
• updating the instruction data by adapting the action instruction to the digital central model updated, and
• transmitting, to the at least one coordinated road user, the updated instruction data of the action instruction updated for the at least one coordinated road user;
• perform, based on the digital central model provided from the server device, the comparison to determine the delta data of the road user describing a difference between the real environment of the road user and the digital central model provided from the server device;
