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.

Intrusion detection system

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.

Inspection system

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.

Control device and control method

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.

Program update control system and program update control method

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.
