摘要： An abnormality detection device is mounted on an engine control device that calculates a target load factor by using a target torque, converts the target load factor to a target throttle opening, calculates a target ignition timing by using a target efficiency, and controls an engine based on the target throttle opening and the target ignition timing. In the abnormality detection device, a target efficiency for monitoring is calculated by using the target ignition timing, a target torque for monitoring is calculated by using the target efficiency for monitoring and the target load factor, a torque deviation between the target torque for monitoring and the target torque is calculated, and the presence or absence of an abnormality is detected by using the torque deviation.

摘要： A controller for an engine controls a throttle opening degree. The controller includes a target opening degree calculating section that selects either a primary request value for a throttle opening degree that corresponds to a torque request or a secondary request value that corresponds to another request and that calculates a target throttle opening degree from the selected one of the first and secondary request values. If the primary request value has been selected, an abnormality occurrence determining section determines whether or not an abnormality has occurred, in accordance with a magnitude of a deviation of the primary request value from the target throttle opening degree. If the secondary request value has been selected, the abnormality occurrence determining section determines whether or not an abnormality has occurred, in accordance with whether or not the target throttle opening degree is greater than or equal to a predetermined upper limit value.
