Provided is a computer system which, by transmitting software to a terminal for updating a control system of the terminal, enables the terminal to properly function based on the software. A computer system configured so as to be able to remotely update software of a terminal, wherein a processor generates an update file for updating the software of the terminal and stores the generated update file in a memory, identifies a specific terminal to which the update file should be transmitted, reads the update file from the memory and transmits the update file from a transmission module to the specific terminal, receives operational information of the update file from the specific terminal via a reception module, and determines whether it is necessary to distribute the update file to a terminal other than the specific terminal based on the operational information.

Computer system, method of updating software with computer system, and program therefor

Software is prevented from being distributed due to a human-caused error. A software distribution system includes a software distribution server that uses a campaign to manage an update of a function for an in-vehicle device of a vehicle and remotely distributes software based on the campaign, a terminal that executes input and output, and a software update device that is attached to the vehicle and configured to download the distributed software and install the software in the in-vehicle device. In the software distribution system, when the creation of the campaign is requested, statistical information of updated amounts of the software updated based on the most recent multiple campaigns in the target in-vehicle device for the requested campaign is compared with an updated amount of the software updated based on the requested campaign. When a predetermined requirement is satisfied, the requested campaign is not created and a predetermined alert is notified.

Software distribution system, software distribution server, and software distribution method

Control for the flexible distribution of update software is realized. An in-vehicle software distribution systemis configured comprising an in-vehicle software distribution server (telematics center) which manages updates to an identical function by means of a campaign for an in-vehicle system (an engine ECU, for example) of a plurality of vehiclesand distributes software of the campaign remotely to target vehicles, a terminal, and a software update apparatuswhich is mounted in each of the plurality of vehicles. Furthermore, in the telematics center, a campaign management unitcategorizes the campaign target vehicles into groups based on a predetermined criterion and creates a plurality of sub-campaigns which are subordinate to the campaign for each of the categorized groups, and a software distribution unit (an update software distribution unit) distributes software remotely to the target vehicles for each of the sub-campaigns.

In-vehicle software distribution system, in-vehicle software distribution server, and in-vehicle software distribution method

A telematics center includes an update software distribution unit that distributes update software for updating software of an ECU to a software updating device. The software updating device includes a storage device that stores update software distributed from the telematics center and stores update information regarding influence on the operation of a vehicle in a case where the updating of the software of the ECU is not successful and an ECU software updating unit that updates the software of the ECU by using the update software stored in the storage device, and controls the operation of the ECU software updating unit on the basis of the update information stored in the storage device.

Software update system and server

Provided is a computer system capable of managing the performance of processing upon transmitting software to terminals. The present invention is a computer system comprising a plurality of modules which sequentially execute processing up to transmitting the software to the terminal, a controller which collects an operation log of each of the plurality of modules, and a memory which stores the operation logs collected by the controller, wherein the controller generates an operating performance of a prescribed module among the plurality of modules based on the operation logs stored in the memory.

Computer system, method of managing transmission of software with computer system, program therefor, and recording medium

A driving characteristics diagnosis device, includes: an information acquisition unit that acquires information relating to the operational state of a vehicle; a dangerous driving detection processing unit that detects dangerous driving by a user of the vehicle on the basis of information acquired by the information acquisition unit; a cause estimation processing unit that estimates a cause of the dangerous driving; a driving characteristics diagnosis processing unit that performs diagnosis of driving characteristics for the user on the basis of a result of detection of the dangerous driving by the dangerous driving detection processing unit and the cause of the dangerous driving estimated by the cause estimation processing unit; and a diagnosis result output unit that outputs the result of the diagnosis of driving characteristics diagnosed by the driving characteristics diagnosis processing unit.

Driving characteristics diagnosis device, driving characteristics diagnosis system, driving characteristics diagnosis method, information output device, and information output method

A driving diagnosis method and driving diagnosis apparatus enable drivers to recognize where their own driving diagnosis result is located in the driving behavior distribution of a safe driver group and the driving behavior distribution of a dangerous driver group. The degree of a driver's dangerous driving behavior is set as a horizontal axis, the number of drivers according to the dangerous driving behavior degree is set as a vertical axis, and screen information including distributions of a safe driver group and a dangerous driver group as determined by using travel history information about the drivers stored in a storage unit, and a diagnosis result of the dangerous driving behavior of a diagnosis target driver is generated and output.

Driving diagnosis method and driving diagnosis apparatus

A method of diagnosing operating characteristics of a vehicle by a server device includes: obtaining operating characteristics information relative to the operating characteristics of the vehicle; and diagnosing the operating characteristics of the vehicle based upon feature information relative to a feature of a driver of the vehicle registered in advance in the server device and the operating characteristics information obtained from the vehicle.

Method of diagnosing operating characteristics

Provided is a communication system capable of enhancing convenience for remotely operating a movable-body-mounted apparatus mountable in a movable body such as a vehicle. For example, a communication system includes a movable-body-mounted apparatus including: a movable body information storage part which stores movable body information including a received signal quality of a radio wave used for communication to/from a center server and information on a vehicle; a separation determination part which determines whether or not a user who moves along with the vehicle is separated from the vehicle; and a movable body information notification part which notifies the user of the movable body information stored in the movable body information storage part when the separation determination part determines that the user is separated from the vehicle.

Communication system, movable-body-mounted apparatus, terminal device, and center server

A navigation system for an electric vehicle includes a telematics center, a display terminal, and a charging station. In response to a request from the display terminal, the telematics center sends a route search result, which is created based on information on an electric vehicle and the charging station and which includes base point information whose remaining battery capacity is to be confirmed, to the display terminal. The display terminal displays route guidance information, the current position, and a result of comparison between the current remaining battery capacity and the base point information to the user who is driving the electric vehicle.
