Abstract

A steering control device has a steering actuator as an operation target, the steering actuator includes a motor and a steering mechanism mechanically connected to a rotary shaft of the motor. The steering control device includes a controller (62) configured to perform i) a low-temperature process of changing a torque of the motor when an estimated value (Tge) estimated from a temperature of a lubrication target part of the steering mechanism is equal to or lower than a predetermined value with respect to when the estimated value (Tge) is higher than the predetermined value and ii) an estimation process of calculating the estimated value (Tge) which is set be lower than a detected value (Tbc) of a temperature sensor (68) detecting a temperature of a predetermined member attached to the steering mechanism based on a heat emission parameter of the steering actuator associated with a current flow with the detected value (Tbc) as an input.
