摘要： PROBLEM TO BE SOLVED: To provide an anomaly determination device for accurately determining the occurrence of an abnormalities in a rotation sensor.
SOLUTION: A rotation sensor includes a main sensor and a sub-sensor wherein conditions are established that an output signal of the main sensor changes, in a state where an output signal of the sub-sensor is a high signal, each time a crankshaft rotates by a prescribed angle. When these conditions are established, in a state where there are no pulse signals being output from the rotation sensor, a pulse signal is output (at time t51 and t55) whose output width is a prescribed period TS, when the output signal of the main sensor falls, while a pulse signal is being output (time t52) whose output width is a prescribed period TL, that is longer than the prescribed period TS. Time intervals (T0, T1, and T2) between output start times of the respective pulse signals are calculated, while the rotation sensor is determined as being abnormal, when the difference between two consecutively calculated time intervals is larger than a determination value.

Under a condition that a trip counter value Kn is less than a predetermined counter value Kp (YES in a step S430), the automatic stop processing is determined to be executed by the automatic stop execution determining processing, and executed. Meanwhile, under a condition that the trip counter value Kn is the predetermined counter value Kp or more (NO in the step S430), the automatic stop processing is determined not to be executed, and inhibited.

Also, the ECU 41 determines whether or not a double signal abnormality where two signals are output from the crank position sensor 42 each time the tooth 52 passes is generated, and changes determination configurations of the tooth-missing section passage determination according to the cases in which the double signal abnormality is determined to be present and absent, upon performing the tooth-missing passage determination.

SOLUTION: A rotation sensor includes a main sensor and a sub-sensor which are sensor units, with each outputting pulsing signals, in response to changes in the rotating angle of a crankshaft and which output signals out of phase with respect to each other.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an on-vehicle internal combustion engine allowing automatic stop and restart based on vehicle operation, which can improve the restartability of the engine.
SOLUTION: The device controls an on-vehicle internal combustion engine 10 which includes a manual transmission 32 and allows automatic stop and restart under prescribed conditions of vehicle operation. Idle rotation speed is set as a target rotation speed related to engine operation when no stepping of an accelerator pedal is executed in the restart utilizing a starter 20 based on the establishment of restart conditions after a stop command is issued under prescribed conditions including a state where a transmission stage of the manual transmission 32 is in a neutral position. When engine rotation speed is not less than fuel cut permission rotation speed higher than idling rotation speed, fuel cut is temporarily executed with respect to the internal combustion engine. When the transmission stage of the manual transmission 32 is shifted from neutral position to a first speed position after restart conditions are established, however, the execution of fuel cut is prohibited.
