    摘要: The in-vehicle control system in which a plurality of ECUs for controlling in-vehicle devices are connected to be able to communicate with each other is provided with an information set setting unit for setting an information set by combining information targeting different ECUs from among the original information relating to control functions of sound ECUs, an information collecting unit for collecting present information corresponding to the original information from each of the ECUs targeted by the information set, and an abnormality detection unit for detecting any one of the ECUs targeted to be abnormal when a degree of coincidence between correct answer information calculated by an evaluation function f with the information set as an argument and an evaluation value calculated by the evaluation function with the present information corresponding to the information set as an argument is lower than a criterion.

    摘要: A first processing environment includes: a control processing unit configured to execute control processing on a control subject; a first storage area for storing data for controlling the control subject; and a verification determination unit. A second processing environment includes: a second storage area for storing an expected value; a verification value generation unit; and a verification execution unit. The verification value generation unit generates the verification value before the control processing is stopped. The verification execution unit executes comparison processing of comparing the expected value and the verification value before the control processing is activated. When the comparison result indicates a verification success, the verification determination unit executes determination processing of determining that the control processing is to be activated, and executes determination processing of determining that activation of the control processing is to be stopped when the comparison result indicates a verification failure.

    摘要: An intrusion detection system comprises: a monitor listing for setting a rule(s) on which determination is performed whether communications data is normal or abnormal in every one of respective states; an intrusion detection unit for acquiring communications data flowing through a communications line(s), and for performing, by comparing the communications data with the monitor listing, determination on the presence or absence of abnormality in the communications data; a state management unit for acquiring a state of a host motor vehicle and/or that of a control device, and for changing over the monitor listing for use in the intrusion detection unit; and a processing time management unit for giving rise to increasing a processing time(s) of the intrusion detection unit in accordance with processing content of the intrusion detection unit.

    摘要: In a test device, a communication unit sequentially receives messages partially including a test target signal of a plurality of bits transmitted from an ECU. A judgment unit checks the value of the test target signal included in a message received by the communication unit in a first duration against a first expected value, checks the value of the test target signal included in a message received by the communication unit in a second duration different from the first duration against a second expected value acquired by inverting each bit of the first expected value, and judges a test on the ECU as pass or fail based on both of the check results.

    摘要: Provided is an inspection system capable of inspecting whether or not a control device mounted to a vehicle normally operates also during usage. An inspection information generation unit of a server generates security inspection information for use in inspection of a function of an ECU on the basis of ECU design information and security information, and the security inspection information is transmitted to an ECU_GW. In the ECU_GW having received the security inspection information, an ECU_GW control unit performs a conversion process, and transmits information obtained by the conversion process to an ECU_A and an ECU_B. When receiving the information, each of the ECU_A and the ECU_B determines, with use of a determination reference held in advance, whether the received information is normal or abnormal.

    摘要: An in-vehicle use control system includes: a state management part which acquires the information on an operational state of the system; a memory storage part which memorizes the information on the operational state of the system, which is acquired by the state management part; a control part which has a plurality of control functions; a list management part which holds lists in which the correspondence relation between the control function of the control part and the normal operating state of the control function is defined; and a monitoring part which chooses the list held in the list management part, based on the operational state which is memorized in the memory storage part, compares the normal operating state of a control function which is defined in the list, and an execution state of the control part, and monitors whether the operation of the control function is normal or not.

    摘要: A first control device includes a data processing controller that generates and transfers information indicating a current operating condition of the first control device and information indicating a current operating condition of a vehicle, and transfers a most recent version of a security program, to which the program is to be updated, to a second control device, while the second control device, having received the most recent version of the security program from the first control device, specifies the current operating condition of the vehicle on the basis of the information obtained from the first control device, and when the specified current operating condition matches a vehicle operating condition in which processing for updating the program to the most recent version of the security program is possible, executes processing for updating the program to the most recent version of the security program.

    摘要: Before a communication control device ECU falls into a sleep state or a power-off state, a substitution request is transmitted to an ECU, among substitute candidate devices ECU to ECU, that is determined by a substitute transmission acceptability determining unit as being capable of taking over the communication control device. A substitution-capable processing load quantity, a substitution-capable process importance level, or a failure determination result of each of the ECUs is used as determination criteria when the substitute transmission acceptability determining unit of the ECU determines a substitute device, and the determination is carried out in an order that takes into consideration the process importance level of each of the ECUs during travelling or at a standstill, to prevent failures in a network or abnormal behaviors of a vehicle.
