Abstract
An abnormality testing apparatus that accurately tests an abnormality at an early stage is disclosed. The apparatus includes means for manipulating a variable. The variable manipulating means computes the variable based on the state of the engine and manipulates the computed variable according to the state of the engine. The state includes a state in which the engine is not running. The apparatus performs at least one of the abnormality test and judgment whether a test condition is satisfied according to the variable.
Claims22
An apparatus for testing an abnormality of an engine system, comprising:
- means for manipulating a variable, wherein the variable manipulating means computes a variable that relates to the engine system based on the state of an engine and manipulates the variable in accordance with the state of the engine, and wherein the apparatus performs at least one of the abnormality test and judgment whether a test condition is satisfied according to the variable;
- wherein the variable manipulating means manipulates the variable in the state of the engine, wherein the state is a state in which the engine is not running.
An apparatus for testing an abnormality of an engine system, comprising:
- means for manipulating a variable, wherein the variable manipulating means computes a variable that relates to the engine system based on the state of an engine and manipulates the variable in accordance with the state of the engine, and wherein the apparatus performs at least one of the abnormality test and judgment whether a test condition is satisfied according to the variable;
- wherein, when the engine is started, the variable manipulating means manipulates the variable based on the value of the variable that was manipulated when the engine was stopped immediately before and on historical data that represents the state of the engine, wherein the state is a state in which the engine is not running.
A method for testing an abnormality of an engine system, comprising:
- computing a variable that relates to the engine system based on the state of an engine;
- manipulating the variable in accordance with the state of the engine, wherein the state is a state in which the engine is not running;
- and
- performing at least one of the abnormality test and judgement whether a test condition is satisfied according to the variable.
