Abstract: A data processing device has a communicator that receives, from a data overwriter, first device-specific information that identifies one of the plural same-ID data processing devices as a data overwrite object device having data to be overwritten by the data overwriter. Then, a device-specific information generator in the data processing device generates second device-specific information that is used to determine whether a subject data processing device is the data overwrite object device. Then, a specifier in the subject data processing device specifies that (i) the subject data processing device is the data overwrite object device or (ii) one of other plural same-ID data processing devices other than the subject data processing device is the data overwrite object device, based on a matching between (a) the first device-specific information received from the data overwriter, and (b) the second device-specific information generated by the device-specific information generator.

Abstract: A control device for a vehicle includes: a plurality of controllers, each of which executes a plurality of energy saving control modes for restricting reduction of driving energy of the vehicle; a selector for displaying the plurality of energy saving control modes at the same time and for prompting an user of the vehicle to select execution or rejection of one of the plurality of energy saving control modes; and a central control device for controlling one of the plurality of controllers to execute a corresponding energy saving control mode, of which the execution is selected by the user, so that a maximum cruising range of the vehicle is expanded without providing a feeling of discomfort.
