Abstract: An electronic control device that executes arithmetic processing for controlling an operation of a vehicle includes: a determination unit that is connected to one or a plurality of electronic devices that recognize an external environment on the basis of information of a sensor provided in the vehicle and determines an operation of the vehicle on the basis of external recognition information transmitted from the electronic devices; and a functional boundary change determination unit that determines changes in functions of the electronic control device and the electronic devices if it is determined that a processing load of the electronic control device is high.

Abstract: Provided is a resolution control device that suppresses a processing load of output data by dynamically controlling a resolution at time of processing the output data of an external-environment sensor based on a traveling status. The resolution control device processes output data of an external-environment sensor that recognizes a surrounding environment of a vehicle and outputs the processed output data to an automatic driving device. The resolution control device includes a traveling status determination unit that determines a traveling status of the vehicle, and a control unit that extracts an attention region of the output data based on the traveling status, reduces a resolution of a region other than the attention region, and then outputs the region to the automatic driving device.

Abstract: The present invention provides a software management device capable of converting a term used in a model and an abstraction level thereof. A software management device 1 includes: an input unit 2 that inputs a target model; a storage unit 3 that hierarchically stores functions and/or names constituting the model; and an in-model name replacement unit 6 that selects a corresponding function and/or name from the storage unit 3 according to the input model input from the input unit 2, and replaces a function and/or a name in the input model with the selected function and/or name.
