Claim:
1. A steering control apparatus comprising: an assist deviation calculator calculating an assist deviation between (i) a detected steering torque that is a detection value of a steering torque, and (ii) a target steering torque that is targeted in an assist control that is performed for decreasing a steering load; a follow deviation calculator calculating a follow deviation between (i) a detected physical quantity of steering operation that has a measurement unit other than a torque, and (ii) a target physical quantity in a control of a vehicle trajectory control; a unit converter converting a measurement unit for at least one of the assist deviation and the follow deviation, for a matching of the measurement unit of the respective deviations; a weighting factor setter setting a weighting factor for each of the assist deviation and the follow deviation, based on a degree of driver intervention in the vehicle trajectory control, and a degree of necessity of the vehicle trajectory control; a deviation mixer calculating a controlled deviation by mixing the assist deviation and the follow deviation, according to the setting by the weighting factor setter; and an instruction value generator generating an assist instruction value that drives a motor to output (i) an automatic steering torque for the vehicle trajectory control and (ii) an assist torque for the assist control, the assist instruction value is generated based on the controlled deviation calculated by the deviation mixer, to decrease the controlled deviation.
