Patent number: 9279744Abstract: Any one of ECUs that are operating detects a present power supply voltage repeatedly. When the voltage detected at the present time is changed from the voltage detected at the previous time, a difference is calculated as a variation value and the repeatedly calculated variation values are integrated to provide a voltage variation integrated value. When the variation of the power supply voltage of an ECU becomes great relatively due to a loose connection in a power supply line, the calculated voltage variation integrated value becomes greater than those of the other ECUs. In addition, when a defect arises in a common power supply source, the voltage variation integrated value increases in all the ECUs. Therefore, each integrated value of the variation values of the power supply voltage in each of the ECUs enables an anomaly diagnosis of an occurrence point of the defect.Type: GrantFiled: April 7, 2014Date of Patent: March 8, 2016Assignee: DENSO CORPORATIONInventor: Motohiro Yasue

Patent number: 9159178Abstract: An in-vehicle control system includes an in-vehicle control apparatus and a different in-vehicle apparatus communicably connected with each other. The different in-vehicle apparatus outputs detection data including a vehicle signal, result information indicating a diagnostic result of a self-diagnostic process, and time information indicating elapsed time measured from an appearance of an abnormal symptom in the vehicle signal. The in-vehicle control apparatus stores at least the vehicle signal as preliminary analysis data in a first storage in time series, and reads out, from the first storage, one preliminary analysis data upon a confirmation of an abnormality detection data including the result information indicating abnormality occurrence. The readout data is stored prior to a confirmation time of the abnormality detection data by the measured elapsed time. Then, the in-vehicle control apparatus stores the readout data in a second storage as an analysis data.Type: GrantFiled: May 14, 2014Date of Patent: October 13, 2015Assignee: DENSO CORPORATIONInventor: Motohiro Yasue

Patent number: 8346406Abstract: A first microcomputer in an ECU outputs a CID of the ECU in response to a request from a scan tool when the ECU has multiple microcomputers implemented therein. Each of the multiple microcomputers has an additive value stored therein for counting an update of the software. The additive values from the multiple microcomputers are added as a sum total of the ECU that is further added to a CID base value. The sum total of the ECU added to the CID base value is then output as the CID of the ECU from the first microcomputer to the scan tool. Therefore, information stored in the first microcomputer is not necessarily changed for outputting an updated CID (e.g., software product number information) from the ECU.Type: GrantFiled: April 25, 2012Date of Patent: January 1, 2013Assignee: Denso CorporationInventors: Mikio Teramura, Kokichi Shimizu, Motohiro Yasue

Patent number: 8280579Abstract: A vehicular memory management apparatus includes in an SRAM a mirror area for mirroring information from a PDTC storage area and an update information storage area for storing update information of the SRAM. When a fault is detected, a DTC is stored in both of the mirror area and a DTC storage area for maintaining consistency between the contents of the two areas, and the update information is updated. After confirming the consistency based on the update information, the information in the mirror area is copied to the PDTC storage area. Further, the information in the PDTC storage area is copied to the mirror area upon determining that the information in the mirror area is deleted based on the update information.Type: GrantFiled: September 10, 2008Date of Patent: October 2, 2012Assignee: Denso CorporationInventors: Motohiro Yasue, Takeshi Suganuma

Patent number: 8095263Abstract: When an electronic control unit receives a rewriting request of vehicle identification information, the electronic control unit writes state information indicating a rewriting state in a memory and rewrites the vehicle identification information into new vehicle identification information. The electronic control unit sends an erasing order to a peripheral electronic unit for erasing failure information stored in the peripheral electronic unit and determines whether the peripheral electronic control unit sends an erasing completion signal indicating that the erasing of the failure information is completed. The electronic control unit erases the state information indicating the rewriting state when the rewriting of the vehicle identification information is completed and the peripheral electronic control unit sends the erasing completion signal.Type: GrantFiled: April 6, 2009Date of Patent: January 10, 2012Assignee: Denso CorporationInventors: Motohiro Yasue, Kokichi Shimizu, Kazunori Okada
