COMPUTER IMPLEMENTED METHOD FOR PROVIDING A VEHICLE SERVICE AND TRIGGERING A PROCESS TO PAY FOR THE VEHICLE SERVICE, SOFTWARE PROGRAM, AND SYSTEM

The invention relates to a computer implemented method for providing a vehicle service and triggering a process to pay for the vehicle service. The method comprises the steps: establishing (S10) a data connection (10) between a service point unit (3) for providing the vehicle service and an electronic control unit (2) of a vehicle (1), and gathering initial vehicle service data at a start of a provision of the vehicle service in the electronic control unit (2), wherein the initial vehicle service data comprise a timestamp of establishing the data connection (10), identification data (11a) of the vehicle (1), and at the time of the timestamp at least one value (11b) of a state of the vehicle (1) indicating a quantity which is to be altered by the provision of the vehicle service; storing (S20) the initial vehicle service data and final vehicle service data gathered in the electronic control unit (2), which are updated initial vehicle service data at an end of the completion of the provision of the vehicle service, consecutively or along with each other on a blockchain network (5) configured to be resistant to modification of data, and storing (S24) on the blockchain network (5) service provider service data of the completed vehicle service gathered in a service provider communication unit (4), which is connected to the service point unit (3); checking (S25) on the blockchain network (5) the validity of the provision of the vehicle service by comparing at least a first numerical value (20b; 20d) of the initial and final vehicle service data of a predetermined unit with at least a second numerical value (24b) of the provider service data of the completed vehicle service of the predetermined unit, such that the validity is positive, when the first (20b; 20d) and second (24a; 24b) numerical values and/or a third numerical value, which results from the comparison based on an arithmetical operation using the first (20b; 20d) and second (24a; 24b) numerical values, are/is within a predetermined range of numerical values or below/above a predetermined threshold value, and; when the validity is positive, triggering (S26) on the blockchain network (5) the process to pay for the vehicle service. Other aspects of the invention are a software program realizing the method and a system for checking the validity of the provision of the vehicle service and triggering the process to pay for the vehicle service.
