1. A method for updating a digital system in a vehicle having an onboard client computer configured to communicate with a remote server, an onboard monitor-control unit operatively connected to the onboard client computer via an onboard communications network, and an electrical energy accumulator device for powering the onboard client computer and the onboard monitor-control unit, the method comprising:
downloading a file from the remote server using the onboard client computer as long as the electrical energy accumulator device is capable of being recharged, the client computer constantly storing a progression point of the download in such a manner as to stop the download when a risk of degradation of communication with the remote server is detected, and resuming the download starting from the progression point that was stored upon detecting a disappearance of the risk of degradation in communication with the remote server;
distributing at least part of the file that was downloaded to the onboard monitor-control unit using the onboard client computer;
installing in the onboard monitor-control unit all or a portion of the at least part of the file that was distributed;
activating the at least part of the file that was installed after stopping the vehicle using the onboard monitor-control unit,
the electrical energy accumulator device not being capable of being recharged constituting a condition for detection of the risk of degradation in communication with the remote server.
