摘要： A method and apparatus for monitoring the operability status of nodes of a communication network determines first node status data at a first node by causing it to diagnose its own status and the status of at least one second node, and to send the first node status data to at least one second node. The first node receives second node status data from at least one second node, and determines node status evaluation data at the first node based on the determined first node status data and the received second node status data.

摘要： Mutual node-fault monitoring keeps the values of abnormality counters, which keep track of error occurrences, consistent among all nodes. However, in some cases, the counter values may become inconsistent among the nodes depending on the error situation.In a distributed system having a plurality of nodes connected via a network, each of the plurality of nodes includes: an error monitor unit for monitoring an error in each of the other nodes; a send/receive unit for sending and receiving data for detecting abnormalities in the other nodes, to and from each of the other nodes via the network, thereby exchanging error monitor results; an abnormality determination unit for determining a node abnormality based on the exchanged error monitor results; a counter unit for counting occurrences of the abnormality for the node determined as having the abnormality; and a counter synchronization unit for synchronizing abnormality counter values after exchanging the counter values with each of the other nodes.

摘要： To reduce the man-hour required in tuning control parameters, a vehicular control system of this invention comprises a user parameter input module, an external parameter input module, a plurality of objective functions, a policy setting module, and a policy node. The user parameter input module inputs a user parameter corresponding to an operation of a user. The external parameter input module inputs an external parameter resulting from an outside environment. The objective functions are set for each control characteristic respectively so as to calculate an internal parameter of each control target from the user parameter and the external parameter. The policy setting module sets policies indicating a control index of the user for the objective functions respectively. The policy node weights the objective functions on the basis of the policies, adjusts the internal parameter in accordance with the policy so that the internal parameter is optimized (minimized or maximized) among the objective functions, and issues a command to a control node corresponding to the internal parameter.

摘要： A power supply semiconductor IC includes: an output transistor connected between a voltage-input terminal and a voltage-output terminal; a control circuit that controls the output transistor based on a feedback voltage of an output voltage; a current-limit circuit that limits an output current of the output transistor such that the output current is not equal to or greater than a current limit; a first transistor constituting a current-mirror circuit with the output transistor; a short-circuit-fault detection circuit that detects a short circuit of the voltage-output terminal based on a voltage across a resistor connected in series to the first transistor; and a first output terminal that outputs a detection result of the short-circuit-fault detection circuit. The current limit is within a detection range of the short-circuit-fault detection circuit. The short-circuit-fault detection circuit detects a short circuit of the voltage-output terminal even while the current limit circuit limits the output current.
