Method of controlling occupation of a space for a vehicle, the method comprising the steps of: - a) executing an application on a portable device of a driver of the vehicle, said portable device being provided with a localization system for identifying the location of the portable device, and said application being connected to a data management platform for receiving information regarding location and state of spaces set by the data management platform, the state being free or occupied; - b) connecting the application to the vehicle by means of a WPAN (wireless personal area network) data transmission protocol implemented both on a device which is permanently on-board the vehicle and on the portable device, wherein the location of the vehicle is provided by the application to the data management platform as the location identified by the localization system; - c) identifying, by means of said application connected to said data management platform, a space at the free state at a location in the proximity of the location of the vehicle; - d) transmitting a request of reservation of said space at free state from the application to the data management platform, - d') confirming the reservation from the data management platform to the application; - e) setting the occupied state of the space in the data management platform and - f) starting calculation of the amount of time for which the space is occupied in the data management platform; - g) reaching the space with the vehicle and physically occupying it; - h) continuing to calculate the occupation time of the space, if the connection of the application to the vehicle via the WPAN data transmission protocol is interrupted or - i) interrupting the calculation of the occupation time of the space, if the connection of the application to the vehicle via the WPAN data transmission protocol is active and the location of the portable device is at a distance greater than a predetermined distance from the space, wherein the data management platform set the state of the space at free if calculation is interrupted, wherein said step of calculating the occupation time of the space is started before the space is reached and after confirmation of the reservation, when the vehicle is in a position at a distance less than the predetermined distance from the space. - a) executing an application on a portable device of a driver of the vehicle, said portable device being provided with a localization system for identifying the location of the portable device, and said application being connected to a data management platform for receiving information regarding location and state of spaces set by the data management platform, the state being free or occupied; - b) connecting the application to the vehicle by means of a WPAN (wireless personal area network) data transmission protocol implemented both on a device which is permanently on-board the vehicle and on the portable device, wherein the location of the vehicle is provided by the application to the data management platform as the location identified by the localization system; - c) identifying, by means of said application connected to said data management platform, a space at the free state at a location in the proximity of the location of the vehicle; - d) transmitting a request of reservation of said space at free state from the application to the data management platform, - d') confirming the reservation from the data management platform to the application; - e) setting the occupied state of the space in the data management platform and - f) starting calculation of the amount of time for which the space is occupied in the data management platform; - g) reaching the space with the vehicle and physically occupying it; - h) continuing to calculate the occupation time of the space, if the connection of the application to the vehicle via the WPAN data transmission protocol is interrupted or - i) interrupting the calculation of the occupation time of the space, if the connection of the application to the vehicle via the WPAN data transmission protocol is active and the location of the portable device is at a distance greater than a predetermined distance from the space, wherein the data management platform set the state of the space at free if calculation is interrupted, wherein said step of calculating the occupation time of the space is started before the space is reached and after confirmation of the reservation, when the vehicle is in a position at a distance less than the predetermined distance from the space.
