PROBLEM TO BE SOLVED: To provide a drive control device which can determine normality/abnormality of a real crank angle detection part with a high accuracy.SOLUTION: A crank angle sensor 12 can detect a real crank angle which is a real rotation angle of a crank shaft, and output a real angle signal which is a signal corresponding to the detected real crank angle. A resolver 22 can detect a motor angle which is a rotation angle of a motor shaft, and output a motor angle signal corresponding to the detected motor angle. A pseudo crank angle calculation part 51 can calculate a pseudo crank angle which is a pseudo rotation angle of the crank shaft on the basis of the motor angle signal outputted from the resolver 22, and output a pseudo crank angle signal which is a signal corresponding to the calculated pseudo crank angle. A normality/abnormality determination part 52 can determine normality/abnormality of the crank angle sensor 12 by comparing the real crank angle signal outputted from the crank angle sensor 12 and the pseudo crank angle signal outputted from the pseudo crank angle calculation part 51 with each other.SELECTED DRAWING: Figure 2 |
