Abstract: A power distribution box (PDB) includes relays to connect a vehicle battery to corresponding electronic control units (ECUs) of a vehicle. A processor is programmed to instruct the PDB via a control interface to cause one of the relays to power a target ECU, send a sleep command over a vehicle bus to cause powered ECUs other than the target ECU to sleep, and install a software update to the target ECU.

Abstract: A system includes a first storage, a second storage, and a vehicle electronic control unit (ECU). The ECU is programmed to download a software update received from a server to the first storage, at keyoff, attempt a reboot of the ECU before vehicle shutdown, and confirm the first storage as being active for booting instead of the second storage, responsive to the vehicle ECU successfully booting to the first storage.

Abstract: A system includes a processor controlling a vehicle module (VM) in communication with a telematics control unit (TCU) over a bus. In this embodiment, the processor is configured to receive an authentication request, including a counter value, from the TCU. The processor is also configured to respond to the authentication request based on comparison of the counter value to a stored counter value stored by the VM. The processor is further configured to receive a command corresponding to the authentication request and including the counter value, responsive to the approved authentication request and process the command based on comparison of the counter value to the stored counter value.

Abstract: Systems, devices, and methods are disclosed for determining whether to provide an over-the-air (OTA) update to a vehicle. An example method includes determining an update characteristic of a pending software update for a vehicle. The method also includes determining a vehicle battery state of charge (SOC) threshold based on the update characteristic. The method further includes modifying the threshold based on a location of the vehicle. The method still further includes determining a SOC of a battery of the vehicle. And the method yet further includes responsively providing the pending software update to the vehicle based on the SOC and the threshold.

Abstract: A vehicle includes a controller and a processor. The processor is programmed to prompt the user with a selection to install a software update to the controller responsive to a user preference value, computed from user selections whether or not to install software updates associated with contextual information that matches a software update to be installed, exceeding a threshold defined by a priority of the software update, and update the user preference value per the selection.

Abstract: A vehicle includes an engine and at least one controller. The at least one controller periodically determines an estimated current to be demanded by vehicle electrical loads during an auto stop of the engine, compares the estimated current with a threshold current, and inhibits an auto stop of the engine if the estimated current is greater than the threshold current for a predetermined period of time.

Abstract: A system includes a processor configured to query one or more vehicle electronic control unit (ECU) modules to determine current software versions installed on the ECU modules, responsive to a multi-cycle update process resuming. The processor is also configured to pause the update process, responsive to the query identifying a change in at least one software version to a different version from when the update process first began. The processor is additionally configured to report the change to a remote source.

Abstract: A vehicle may include: at least one power source; a plurality of wheels; a motor configured to drive at least one of the plurality of wheels with energy stored in the power source; and at least one processor configured to: break a received route into a plurality of segments; and calculate a route energy consumption rate correction factor (RECF) of a current segment as a function of the following received values: a RECF of a previous segment, an observed energy consumption rate, and an estimated energy consumption rate.
