Abstract
An automatic steering control apparatus includes a steering controller and a steering instruction unit. The steering controller includes a storage, an instruction value checking unit, and a steering control unit, and controls operation of a steering device of a vehicle. The steering instruction unit includes an instruction value calculator and an estimated instruction value calculator, and outputs an instruction value to the steering controller. The instruction value calculator calculates a latest course and calculates the instruction value. The estimated instruction value calculator calculates a future course and calculates an estimated instruction value. The storage stores the estimated instruction value acquired from the estimated instruction value calculator during a past predetermined period. The instruction value checking unit determines whether an abnormality is present in the steering instruction unit by comparing the instruction value for a current point and the estimated instruction value corresponding to the current point.
