Description

Method, computer-readable medium, system, and vehicle for transferring vehicle data between a vehicle and a server external to the vehicle Technical Field The present invention relates to a method for transmitting vehicle data between a vehicle and a server external to the vehicle. The invention also relates to a computer readable medium for transferring vehicle data between a vehicle and a server external to the vehicle, a system for transferring vehicle data between a vehicle and a server external to the vehicle, and a vehicle comprising a system for transferring vehicle data between a vehicle and a server external to the vehicle. Background It is known that a vehicle can transmit status information to a server external to the vehicle in the event of an event in the vehicle. Disclosure of Invention The object of the invention is therefore to effectively improve the transmission of vehicle data between a vehicle and a server external to the vehicle. In particular, the present invention aims to effectively improve the continuous transfer of vehicle data between a vehicle and a server external to the vehicle. This object is solved by the features of the independent claims. Advantageous embodiments and developments of the invention result from the dependent claims. According to a first aspect, the invention features a method for transmitting vehicle data between a vehicle and a server external to the vehicle. The method may be a computer implemented method and/or a controller implemented method. The vehicle data may include one or more vehicle data attributes. The vehicle may be a motor vehicle. The server external to the vehicle may be a server of the cloud computing system, in particular a virtual or physical server. The method includes receiving, by a synchronization component of a server external to the vehicle, a subscription message for reading a vehicle data attribute. The method further includes transmitting a subscribe message for reading the vehicle data attribute from a synchronization component of a server external to the vehicle to the synchronization component of the vehicle, and evaluating, by the synchronization component of the vehicle, the reading of the vehicle data attribute of the subscribe message if the first subscribe parameter is applied. If the reading of the vehicle data attribute of the subscribe message has been successfully evaluated by the synchronizing component in relation to the first subscribe parameter, the method comprises transmitting, by the synchronizing component of the vehicle, the subscribe message for reading the vehicle data attribute to a vehicle data attribute memory of the vehicle, receiving, by the synchronizing component of the vehicle, a subscribe state of the vehicle data attribute memory in response to the transmitted subscribe message for reading the vehicle data attribute, transmitting the received subscribe state from the synchronizing component of the vehicle to a synchronizing component of a server external to the vehicle, receiving, by the synchronizing component of the vehicle, a vehicle data attribute value of the vehicle data attribute memory in response to the transmitted subscribe message for reading the vehicle data attribute, and transmitting, by the synchronizing component of the vehicle, the received vehicle data attribute value to the synchronizing component of the server external to the vehicle. Advantageously, the method may effectively provide vehicle data to a server external to the vehicle. The vehicle transmits only vehicle data for which a subscription message for reading the vehicle data attribute value has been received to a server outside the vehicle. Vehicle data, in particular vehicle data attribute values of the vehicle data attributes, are transmitted only if the vehicle data attribute values in the vehicle change. It is thereby effectively prevented that already transmitted vehicle data, in particular already transmitted vehicle data attribute values of the vehicle data attributes, are not retransmitted from the vehicle to a server external to the vehicle. Furthermore, the method may transmit the vehicle data to a server outside the vehicle, as long as a subscription exists for reading the vehicle data attribute value. The vehicle data properties can thereby be synchronized between the vehicle and a server external to the vehicle. Thus, the current value of the subscribed vehicle data attribute is available on a server external to the vehicle. It is therefore unnecessary to manually and/or individually query the vehicle data attribute values of the individual vehicles by means of a server external to the vehicle. Vehicle data of subscribed vehicle data attributes of a single vehicle and/or a group of multiple vehicles may thus be provided more quickly to applications, such as vehicle apps and/or services, through servers external to the vehicle. According to one advantageous embodiment, the reception of the subscription messag
