摘要： A transmission device is connected to a layer 2 switch through a transmission path at one side, and to a relay transmission path at the other side. The transmission path includes a transmission path of a active system and a transmission path of a stand-by system. When failure occurs in the transmission path of the active system, the transmission device forcibly shuts down the transmission path of the active system upon detection of link down, to stop packet transmission, and causes the layer 2 switch to perform MAC address flush. The transmission device then switches the transmission path of the stand-by system to the active system, and transmits packets through the transmission path that has become the active system as a result of switching. The layer 2 switch performs MAC address learning to set a port, thereby maintaining communication even after occurrence of the failure.

摘要： An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor arranged in the exhaust system of the engine. An ECU determines activation of the air-fuel ratio sensor and carries out feedback control of the air-fuel ratio of a mixture supplied to the engine in response to the output from the air-fuel ratio sensor. An intermediate state of the air-fuel ratio sensor corresponding to a transient state of the air-fuel ratio sensor from an inactive state thereof to an active state thereof is determined. The output from the air-fuel ratio sensor for use in execution of the feedback control is corrected when the air-fuel ratio sensor is in the intermediate state.

摘要： A control apparatus for an internal-combustion engine includes a diagnosis device. The diagnosis device includes a determination section and an exhaust flow rate calculator configured to calculate an exhaust flow rate that reflects a volume flow amount of exhaust gas. A filter is configured to filter a signal representing an air-fuel ratio so that a 0.5th-order frequency component of engine speed is extracted from the signal. An integrator is configured to accumulate a filtered signal for a predetermined period of time to compute an integration value. A corrector is configured to correct the integration value to compute a corrected integration value each time the integration value is computed by the integrator. The determination section is configured to determine that cylinder-to-cylinder air-fuel ratio imbalance occurs in cylinders if the corrected integration value is greater than a predetermined threshold value after the predetermined period of time has elapsed.
