20090066494 | FAILURE INFORMATION DETECTION DEVICE, FAILURE INFORMATION DETECTION SYSTEM, SERVER, AND FAILURE INFORMATION DETECTION METHOD - A failure information detection device that detects abnormality of a vehicle-mounted device that is mounted in a vehicle has: an attachment detection portion that detects whether a first component part has been attached to the vehicle; an abnormality detection portion that detects abnormality of a second component part that is disposed on the first component part; and an abnormality information discernment portion that discerns that abnormality information regarding the abnormality is not based on a failure of the vehicle-mounted device if the attachment detection portion detects that the first component part has not been attached to the vehicle. | 03-12-2009 |
20090216399 | VEHICLE DIAGNOSING APPARATUS, VEHICLE DIAGNOSING SYSTEM, AND DIAGNOSING METHOD - A vehicle diagnosing apparatus, a vehicle diagnosing system, and a diagnosing method enable the determination of completion of a repair or part replacement on a vehicle while adapting to changes in environment and overcoming temporal or spatial restrictions. The vehicle diagnosing apparatus reads diagnostic information from an on-board diagnosing unit on the vehicle that detects an abnormality in an on-board device. A result of a maintenance work performed on the on-board device is finalized by a maintenance result finalizing unit. A determination unit determines the appropriateness of the finalized maintenance work result with reference to determination information stored in a database that is continuously updated. The result of the determination is indicated by a notifying unit. Analogy is used to obtain the diagnostic information when the on-board device requires a long time or a certain condition to provide accurate diagnostic information. | 08-27-2009 |
20090292417 | VEHICLE FAILURE ANALYSIS SYSTEM, VEHICLE FAILURE ANALYSIS APPARATUS, AND VEHICLE FAILURE ANALYSIS METHOD - A vehicle failure analysis system for a vehicle equipped with a plurality of control systems, each of which includes one or more components, includes: a faulty system identification unit that identifies a faulty control system from among the plurality of control systems; and a faulty component identification unit that identifies a faulty component from among the one or more components which are constituents of the identified control system. | 11-26-2009 |
20100057292 | ABNORMALITY ANALYSIS SYSTEM FOR VEHICLE AND ABNORMALITY ANALYSIS METHOD FOR VEHICLE - When an abnormality of a vehicle is detected based on a vehicle state value that indicates the vehicle state, an abnormality analysis system for the vehicle estimates a cause of the abnormality. The abnormality analysis system includes: a factor identifying information extraction unit that extracts factor identifying information which is used to identify a factor of the abnormality based on the vehicle state value; a database that contains data groups which correspond to respective categories of the factor identifying information and which store causes of abnormalities and vehicle state values at the time of occurrence of the abnormalities; and an abnormality cause estimation unit that executes a process for estimating the cause of the abnormality of the vehicle with the use of the data group that corresponds to the category of the factor identifying information extracted by the factor identifying information extraction unit. | 03-04-2010 |
20100250061 | VEHICLE CONTROL DEVICE - A vehicle control device includes a control unit controlling an in-vehicle device and a status information acquisition unit acquiring status information of a vehicle and output the acquired status information to the control unit. In the vehicle control device, the control unit specifies a failure-cause-verification information to be used for verifying a cause of a failure from among the status information acquired by the status information acquisition unit, the failure-cause-verification information being specified by using a timing when a predetermined fail-safe control is started as a reference, the timing being determined based on the status information acquired by the status information acquisition unit, and the control unit stores the specified failure-cause-verification information in a predetermined storage medium. | 09-30-2010 |
20100268415 | VEHICLE INFORMATION STORAGE APPARATUS - A vehicle information storage apparatus capable of storing necessary information dataset helpful for diagnosis. The vehicle information storage apparatus includes a status information acquiring unit acquiring a dataset of status information items of a vehicle; and a controlling unit determining a time point when the malfunction started based on the dataset of status information items acquired by the status information acquiring unit, and further determines the malfunction-cause-investigation information data to be used for investigating the cause of the malfunction from among the dataset of status information items acquired by the status information acquiring unit based on the specified time point when the malfunction started, and stores the determined malfunction-cause-investigation information data in a prescribed storage medium. | 10-21-2010 |
20110221613 | ABNORMALITY DETECTION APPARATUS - An abnormality detection apparatus has: an abnormality detection portion that detects at least one of an abnormality of a vehicle and an abnormality of an in-vehicle device based on an output of the in-vehicle device that indicates a state of a vehicle; an environmental drive condition information obtaining portion that obtains information regarding an environmental drive condition that affects the output of the in-vehicle device; and an abnormality detection criteria changing portion that changes an abnormality detection criteria used by the abnormality detecting portion based on the environmental drive condition information obtained by the environmental drive condition information obtaining portion. | 09-15-2011 |
20120113773 | INFORMATION RECORDING DEVICE - A CAN driver receives vehicle information sent onto CAN. A diagnosis information acquiring module monitors whether an operation of a diagnosis record ECU itself is normal or not and thus generates diagnosis information. A timestamp information generating module generates timestamp information A per sec and generates timestamp information B in which a time difference from the generation timing of the timestamp information A is expressed on the unit of 1/100 sec. A diagnosis record module, each time the timestamp information generating module generates the timestamp information A, transfers a first type record containing the timestamp information A and the diagnosis information generated at this point of time to a memory manager, and transfers a second type record containing the vehicle information and the timestamp information B generated at this point of time to the memory manager. | 05-10-2012 |
20120299556 | DETERIORATION DEGREE DETERMINING APPARATUS - A deterioration degree determining apparatus determines a deterioration degree of a battery of a vehicle. The device includes an electric component activating part activating a non-driving series electric component of the vehicle by using electric power of the battery to determine the deterioration degree of the battery, a charge degree obtaining part which obtains a charge degree of the battery during a time period in which a charge state of the battery is increased to a designated degree by charging the battery after the battery is discharged for a designated period of time by causing the electric component activating part to activate the non-driving series electric component, the battery being charged by electric power generated by an electric generator of the vehicle; and a deterioration degree determining part determining the deterioration degree of the battery based on the charge degree obtained by the charge degree obtaining part. | 11-29-2012 |
