Abstract: A steering control device is provided with at least one of a first torque correction computing part and a second torque correction computing part; wherein the first torque correction computing part is equipped with a weight computing part which computes an increment of weight based on a magnitude of the driver torque, and accumulates the increment of weight to generate a weight, a clip value computing part which computes an automatic driver torque clip value according to the weight, and a clip processing part which clip processes the automatic driver torque with the automatic driver torque clip value; and the second torque correction computing part is equipped with a gain computing part which computes an increment of gain according to the driver torque, and accumulates the increment of gain to generate a gain, and a gain processing part which outputs an automatic driver torque multiplied by the gain.

Abstract: The quality of joints formed by spot welding, particularly the diameters of the individual nuggets, can accurately and nondestructively be inspected by heating or cooling one of the welded members and measuring the distribution of the surface temperature of the other member because of a maximal heat conduction at each nugget. The surface temperature distribution may be measured merely linearly since the width of a peak on the temperature-distance curve depends on the diameter of a nugget.
