    摘要： A control system configured to control an internal combustion engine includes a crankshaft and an engine speed sensor. The crankshaft is rotated in response to combusting a mixture of air and fuel delivered to at least one cylinder included in the internal combustion engine. The engine output speed sensor is configured to output an engine output speed signal indicating a rotational speed of the crankshaft. An engine control module controls an amount of air and fuel delivered to the at least one cylinder and estimates a torque output based on the amount of air and fuel. A torque compensation module is configured to determine at least one weak cylinder based on the engine output speed signal. The torque compensation module is further configured to determine a torque compensation value that adjusts the estimated torque output based on the weak cylinder.

    摘要： In order to solve a problem that in an internal combustion engine in which abnormal combustion (knocking or an accidental fire) of an engine is detected from an ion signal, the setting of an abnormal combustion determination threshold value under a transient condition in which an engine operating state abruptly changes is difficult to thereby cause erroneous determination, the present invention is an engine control device provided with an ion signal detection means for detecting ions generated during combustion, and provided with an abnormal combustion determination means for determining knocking or an accidental tire according to an ion signal detected by the detection means, the engine control device being characterized by being provided with an in-cylinder temperature estimation means for estimating the in-cylinder temperature in a normal combustion cycle under a current operating condition of the engine, and by setting the knocking determination threshold value or accidental fire determination threshold value of the ion signal on the basis of the estimated in-cylinder temperature information. Consequently, it becomes possible to accurately detect abnormal combustion even under a transient operating condition.

    摘要： Computer-implemented techniques include determining, at a controller of a vehicle, a wheel speed for each of two front wheels of the vehicle and two rear wheels of the vehicle. The techniques include calculating, at the controller, a difference between (i) an average of the wheel speeds for the two front wheels of the vehicle and (ii) an average of the wheel speeds for the two rear wheels of the vehicle to obtain an error. The techniques include setting, at the controller, a rough road detection bit when the error is greater than or equal to a threshold indicative of an error corresponding to rough road. The techniques include monitoring, at the controller, the rough road detection bit for a period to obtain a hysteresis band. The techniques also include determining, at the controller, whether the vehicle is traveling on rough road based on the hysteresis band.

    摘要： Provided is a control apparatus for an internal combustion engine, which can favorably suppress an occurrence of abnormal combustion regardless of its operational conditions. An occurrence probability of abnormal combustion of the internal combustion engine (10) is obtained on the basis of a fuel dilution index. An expected value I of the number of occurrences of abnormal combustion per a predetermined time period is calculated on the basis of the occurrence probability of abnormal combustion. The upper limit value of a torque generated by the internal combustion engine (10) is limited low so that the expected value I does not exceed a predetermined tolerable value.

    摘要： The present invention provides a control apparatus used in an internal combustion engine that can switchably use a compressed natural gas and gasoline. The control apparatus carries out a miss fire check on the internal combustion engine over two or more combustion cycles, and, based on the results of the check, detects failures. The control apparatus prohibits switching of fuels (S23, S24, S28) basically during the miss fire check. If the value of a miss fire counter is not increasing, the control apparatus predicts that a negative check result will not be obtained (S26), and lifts the prohibition on switching of fuels (S29).
