Method and apparatus for vehicle software update installation

A computer-implemented method comprising:

• detecting software ready to be loaded onto a vehicle and existing in memory of the vehicle;
• responsive to a key-off of the vehicle and the detecting, suspending vehicle start up during software update;
• deleting from internal memory an existing software version for which a new software version update exists in external memory in response to the vehicle key-off event and during a key-off state prior to a next key-on event;
• during the key-off state, loading the new software version into the internal memory from the external memory;
• following completion of the deleting and the loading, removing the suspension of vehicle start up;
• and
• responsive to a failure in the loading, deleting the new software version from the internal memory and reloading the existing software version from the external memory.

A non-transitory computer-readable storage medium, storing instructions which, when executed, cause a vehicle processor to perform a method comprising:

• suspending vehicle start-up responsive to a key-off state following detection of a new software version in vehicle memory;
• deleting an existing software version from internal memory in response to the vehicle key-off event and during a key-off state prior to a next key-on event, during the suspension;
• loading the new software version into the internal memory from the external memory during the suspension;
• and
• responsive to a failure in the loading, deleting the new software version from the internal memory and reloading the existing software version from a location where the existing software version exists in the external memory;
• and
• terminating the suspension of vehicle start-up responsive to completion of the reloading.
