US 11,442,721 B2 · Opportunistic software updates during select operational modes

Abstract

Disclosed embodiments relate to opportunistically updating Electronic Control Unit (ECU) software in a vehicle. Operations may include receiving, at a controller in a vehicle, a wireless transmission indicating a need to update software running on at least one ECU in the vehicle; monitoring an operational status of the vehicle to determine whether the vehicle is in a first mode of operation in which an ECU software update is prohibited; delaying the ECU software update when the operational status is prohibited; continuing to monitor the operational status of the vehicle to determine whether the vehicle is in a second mode of operation in which the ECU software update is permitted; and enabling updating of the at least one ECU with the delayed ECU software update when it is determined that the vehicle is in the second mode of operations.

Claims20

Dependent claims

A non-transitory computer-readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for opportunistically updating controller software, the operations comprising:

determining a device is in a first mode of operation at a first time;
accessing a controller software change based on the device being determined to be in the first mode of operation, the controller software change comprising a delta file generated based on comparing two multidimensional grids, each multidimensional grid representing a version of software in multiple dimensions;
and
implementing the controller software change on a controller associated with the device when the device is in the first mode of operation, wherein implementing the controller software change comprises:
storing the delta file adjacent to current software on the controller;
and
linking at least one code segment of the delta file to the current software.
