US Patent 9841970 Vehicle control update methods and systems

A vehicle can include methods and systems to update controls in vehicle modules. The systems and methods can include receiving a control update for a receiving vehicle module to be stored at a first memory location, installing the received controls at the first memory location, running the module using controls at a second memory location, checking the controls at the first memory location, if checking is valid, operating the vehicle module using the controls at the first memory location in place of the controls at the second memory location. The vehicle module can operate the controls at the first memory location without waiting to restart the vehicle or can delay use of the controls until a later event, e.g., restart or download to other vehicle modules on which the current module may depend.
