A control unit is for controlling a wireless communication device usable in a mobile body. The wireless communication device is configured to use first line and second line which are different for a connection to a wireless network, and to transmit and receive data to and from the wireless network via wireless communication. The wireless communication device includes: a data communication processor for performing data communication, which is transmission of data on the first line; and a communication controller for performing communication control for sharing a communication status indicating a progress of data transmission between a transmission source and a transmission destination.

A data collection system includes: an alternativity determination unit determining whether or not data has alternativity, allowing replacement of the data with alternative data when a data necessity inquiry transmitted from an in-vehicle terminal is received by a center-side reception unit; and a center-side transmission unit (i) transmitting a discard notice back to the in-vehicle terminal that has transmitted the data necessity inquiry, and letting the in-vehicle terminal to discard the data based on a determination by the alternativity determination unit that the data has alternativity, and (ii) transmitting a keeping notice back to the in-vehicle terminal that has transmitted the data necessity inquiry, and letting the in-vehicle terminal to keep the data based on a determination by the alternativity determination unit that the data has no alternativity.

Data collection system, collection center and data collection method

An in-vehicle terminal includes: a communication unit; a necessity determination unit; a basic life determination unit that determines a life of data; a life correction unit that corrects the basic life determined by the basic life determination unit according to factors presumed to affect data fluctuations/data change; and a transmission determination unit that determines a transmission order of the data by the data transmission unit based on (i) the transmission necessity of the data determined by the necessity determination unit and (ii) a post-correction life corrected by the life correction unit, in a manner that (a) data having the higher transmission necessity and/or the shorter post-correction life has an earlier transmission order while (b) data having the lower transmission necessity and/or the longer post-correction life has a later transmission order.

In-vehicle terminal, data collection system, and data transmission system

A communication device controls a first communication flow performed by a first terminal and a second communication flow performed by a second terminal. Both of the first communication flow and the second communication flow pass through a sharing section, and the second communication flow has a higher priority than a priority of the first communication flow. The communication device acquires a communication delay in the sharing section; acquires a rated delay of the second communication flow, the rated delay is a communication delay allowed to the second communication flow; and limits input of data from the first communication flow and the second communication flow to the sharing section based on a comparison result between the communication delay of the sharing section and the rated delay.

Communication device and communication method

A driving diagnosis information providing apparatus for a vehicle is disclosed. The driving diagnosis information providing apparatus acquires vehicle information indicative of a vehicle state, and makes a diagnosis of a driving state of the vehicle based on the vehicle information. The driving diagnosis information providing apparatus acquires, as useful information, one of announce information and helpful information. The announce information includes information to be reported to a driver of the vehicle. The helpful information includes information helpful for driving. The driving diagnosis information providing apparatus notifies the driver of diagnosis information indicative of a result of the diagnosis, and notifies the useful information in place of the diagnosis information under a predetermined condition.

Driving diagnosis information providing apparatus and system

An advice provision apparatus calculates the driving condition of the vehicle for every predetermined travel section, for the purpose of comparison with the driving condition in the previous travel section. The driving condition of the current section is evaluated in a relative manner based on the comparison of at least two travel sections, even when the absolute assessment of the driving condition is difficult. Thus, the advice provision apparatus can accurately and precisely diagnose the driving condition of the driver.

Apparatus and method for advice provision and driving condition diagnosis

A driving advice provision apparatus generates an advice, based on diagnosis performed on multiple diagnosis items regarding the driving condition of the vehicle and based on the diagnosis results from those diagnosis items, and provides the generated advice to the driver. The multiple diagnosis items are classified into different categories according to the diagnosis methods. For the diagnosis items suitable to the comparative evaluation rather than the quantitative evaluation, a diagnosis result A for the previous evaluation section is compared with a diagnosis result B for the current evaluation section for yielding a comparative evaluation and for advice generation, thereby enabling an effective advice generation and provision in terms of diagnosis item category.
