Abstract: In a deterioration diagnosis device, a calculation unit estimates a performance of an apparatus during actual operation under a same environmental condition as an environmental condition at a testing time based on operation data including a performance value obtained by measuring a performance of an apparatus during the actual operation, and one or more condition value indicating an environmental condition during the actual operation. The calculation unit calculates a correction factor being a ratio between the performance value obtained by estimation, and a performance value obtained by testing a performance of the apparatus before deterioration. The diagnosis unit compares a performance value obtained by testing a performance of the apparatus after deterioration with a product of a performance value included in new operation data and the correction factor so as perform a deterioration diagnosis of the apparatus.

Abstract: 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.

Abstract: 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.

Abstract: 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.
