Publication number: 20200151972Abstract: An in-vehicle authentication system has a vehicle communication apparatus (100) that is provided in a vehicle equipped with a plurality of ECUs and that communicates with each ECU of the plurality of ECUs. An authentication part (101) performs configuration authentication for authenticating validity of a configuration for each ECU, and registers an ECU that has failed the configuration authentication in an authentication error list. A determination part (102) determines an in-vehicle function that is realizable in the vehicle based on the authentication error list and a function correlation table which indicates correlation between an in-vehicle function realized in the vehicle and an ECU used to realize the in-vehicle function. A display part (107) displays the in-vehicle function determined to be realizable in the vehicle by the determination part (102) on a display (805).Type: ApplicationFiled: May 9, 2017Publication date: May 14, 2020Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Junko NAKAJIMA, Hirohito NISHIYAMA, Ryo MURAMATSU, Yuya TAKATSUKA

Patent number: 10007570Abstract: In an in-vehicle network system (100), a parent control unit (10) and a child control unit (20) constitute a control unit. In the in-vehicle network system (100), a monitoring unit (70) acquires communication data being communicated between the parent control unit (10) and the child control unit (20) and flowing in an in-vehicle network (30) which connects the parent control unit (10) and the child control unit (20) to each other. The monitoring unit (70) diagnoses an abnormality in the parent control unit (10) based on the communication data acquired by the monitoring unit (70) and diagnostic data stored by a memory unit.Type: GrantFiled: December 4, 2013Date of Patent: June 26, 2018Assignee: Mitsubishi Electric CorporationInventors: Yuta Wada, Yuichi Tokunaga, Hirohito Nishiyama, Masuo Ito, Tatsunori Tsujimura, Shigekazu Okamura, Daisuke Tanimoto, Makoto Itoi

Patent number: 9925935Abstract: An increase in the number of signal lines of a control apparatus for controlling devices of an automobile can be prevented and safety of the automobile can be secured. An in-vehicle communication system includes an input DHM that obtains device data from an input device, a BCM that generates control data for controlling an output device based on a value of the device data, and an output DHM that controls the output device according to the control data. The input DHM is composed of duplexed input control blocks, duplexed input shared memories, and an input NW control block. The BCM is composed of a BCM_NW control block, duplexed BCM shared memories for different intended uses, and duplexed arithmetic blocks. The output DHM is composed of an output NW control block, duplexed output shared memories, duplexed output control blocks, and a matching circuit.Type: GrantFiled: August 24, 2012Date of Patent: March 27, 2018Assignee: Mitsubishi Electric CorporationInventors: Hirohito Nishiyama, Masuo Ito, Keisuke Morita, Yuichi Tokunaga, Daisuke Tanimoto, Shigekazu Okamura, Hiroyuki Tsuji, Mitsuhiro Mimura

Patent number: 9787493Abstract: Control information from a plurality of applications 1000 is written into a shared memory 101 as needed. A communication part 105 transmits the control information written in the shared memory 101 to a DHM 200 in each transmission cycle which is constant. In a management table, a plurality of allowable delay times is defined, the allowable delay time being a delay time allowable at an urgent transmission of the control information. A transmission timing notification part 106 divides a transmission cycle into time slots each of which is equal to or shorter than the shortest allowable delay time defined in the management table. The communication part 105 transmits the control information in the shared memory 101 to the DHM 200 before arrival of the transmission cycle, in a unit of time slot.Type: GrantFiled: March 1, 2013Date of Patent: October 10, 2017Assignee: Mitsubishi Electric CorporationInventors: Hirohito Nishiyama, Tatsunori Tsujimura, Shuichiro Senda, Masuo Ito, Makoto Isoda, Shigekazu Okamura, Daisuke Tanimoto

Patent number: 9325629Abstract: When a fixed-cycle transmission timing arrives, a fixed-period communication processing section transmits data in a shared memory to a BCM. An event table storage section stores an event table that indicates a condition of data to be transmitted by an event communication processing section and a permitted delay time, which is the period of time permitted starting from when the data satisfying the condition is extracted, until the data is transmitted. An event detecting section extracts the data in the shared memory satisfying the condition indicated by the event table. The event communication processing section transmits to the BCM the data extracted by the event detecting section, before the arrival of the transmission timing of the fixed-period communication processing section, and by the timing at which the permitted delay time elapses from the time of the data extraction by the event detecting section.Type: GrantFiled: April 20, 2012Date of Patent: April 26, 2016Assignee: Mitsubishi Electric CorporationInventor: Hirohito Nishiyama

Publication number: 20150355917Abstract: A communication unit receives from a BCM output data which is data to I/O devices from the BCM. A shared memory stores the output data received by the communication unit. An anomaly detection communication processing unit and the communication unit generate a communication frame for anomaly detection to request sending the output data held in the BCM. The communication unit sends the communication frame for the anomaly detection to the BCM, and receives the output data held in the BCM from the BCM as a response to the communication frame for the anomaly detection. The anomaly detection checking unit compares the output data received from the BCM with the output data stored in the shared memory.Type: ApplicationFiled: March 1, 2013Publication date: December 10, 2015Applicant: Mitsubishi Electric CorporationInventors: Tatsunori TSUJIMURA, Toshio KOGA, Masashi NOJIMA, Makoto ITOI, Daisuke TANIMOTO, Hirohito NISHIYAMA, Makoto ISODA, Masuo ITO
