Abstract
An engine control device includes a reference voltage memory device (21) for memorizing reference voltage VAFS_STD of AFS (9) for controlling an engine (1) under a normal state, a comparing device (22) for comparing an output voltage VAFS from the AFS (9) when the engine (1) is stopped with the reference voltage VAFS_STD, and calculating a deviation ΔVAFS, and a corrections device (23) for correcting the output voltage VAFS from the AFS (9) (based on the deviation ΔVAFS so that the output voltage VAFS becomes the reference voltage VAFS_STD; A fuel injection quantity Tinj is calculated based on the output voltage VAFS_OBJ from the sensor obtained by the correction device (23), so that engine stall caused by failure of the sensor for controlling the engine is avoided.
Claims18
An engine control device comprising:
- a reference voltage value memory means for memorizing a reference voltage value of a sensor for controlling an engine under a normal state;
- a comparing means for comparing an output voltage value from the sensor under a state that the engine is stopped with the reference voltage value, and calculating a deviation;
- and
- a correction means for correcting the output voltage value from the sensor based on the deviation so as to be the reference voltage value, wherein a fuel injection quantity is calculated based on the output voltage value of the sensor obtained by the correction means.
