Abstract: A method updates a digital system in a vehicle having an onboard client computer that communicates with a remote server, an onboard monitor-control unit operatively connected to the onboard client computer, and an electrical energy accumulator device for powering the onboard client computer and the onboard monitor-control unit. The method includes 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. Then at least part of the file that was downloaded is distributed to the onboard monitor-control unit using the onboard client computer. Then, all or a portion of the at least part of the file that was distributed is installed in the onboard monitor-control unit. Then the at least part of the file that was installed is activated after stopping the vehicle using the onboard monitor-control unit.

Abstract: A method for modifying software in a motor vehicle includes a step of receiving software data and deployment data and steps of verifying the deployment data. If the verification steps are validated, software is modified in the motor vehicle via the software data.

Abstract: A method for installing a computing component in an electronic device fitted in a vehicle, comprising the steps consisting of: receiving a device packet comprising a manifest including a hash value of the computing component; checking the integrity of the manifest; receiving the computing component; checking the correlation between the hash value of the computing component and the computing component received; installing the computing component only in the case of a positive check of the integrity of the manifest and a positive check of the correlation. An associated electronic device is also described.
