Japanese Patent JP7384694

B2

To provide a steering control device capable of appropriately monitoring a state of a transmission mechanism for transmitting rotation of a motor to a steering shaft.SOLUTION: A steering control device controls a steering device having a steering side motor for generating motor torque as power for moving a rack shaft so as to steer a steering wheel of a vehicle, and a transmission mechanism for transmitting rotation of the steering side motor to the rack shaft. The steering control device includes a CPU 50 for monitoring a state of the transmission mechanism. The CPU 50 executes processing of an end abutting determination processing part 71 for determining whether end abutting occurs, processing of a determination value calculation processing part 72 for calculating a damage amount Dmint that is a value obtained by digitizing an end abutting occurrence state on the basis of a determination result of the end abutting determination processing part 71, and processing for determining whether the damage amount Dmint calculated by the determination value calculation processing part 72 is equal to or more than an abnormality determination value Dth so as to detect abnormality of the transmission mechanism.SELECTED DRAWING: Figure 4
