Abstract: PURPOSE:To secure accelerative running ability on a road having high coefficient of friction at the time of control resetting by providing a recovery control means which makes engine output resetting speed faster as a presuming means presumes the coefficient of road to be high for resetting the engine output. CONSTITUTION:When an acceleration slip is controlled by traction control, and the detected value of acceleration slip detected by an acceleration slip detecting means (c) lowers below a fixed value, control completion is judged in a traction control completion judging means (f). At the time of the judging of the traction control completion, a presuming means (g) for coefficient of road friction presumes the coefficient of road friction to be higher as engine output is on the side of high output, and braking force is on the side of low braking force, and a recovery control means (h) makes engine output resetting speed faster as the presuming means (g) for coefficient of road friction presumes the coefficient of road friction to be high to reset the engine output. Thus, accelerative running ability can be secured on the road having the high coefficient of friction at the time of control resetting.

Filed: 1989-10-17
Abstract: PURPOSE:To produce an alloying hot dip galvanized steel sheet excellent in surface chracteristics by degreasing and pickling a steel sheet, forming specific amounts of ferrous oxide on the surface, performing reducing annealing, and then subjecting the steel sheet to hot dip galvanizing and to alloying. CONSTITUTION:Degreasing and pickling are previously applied to a steel sheet to remove impurities, such as Si oxide, in particular. It is desirable to carry out the above pickling by means of electrolytic pickling using H2SO4, etc. Subsequently, heating is applied to the steel sheet up to 400-750 deg.C in a weakly oxidizing atmosphere to form uniformly a ferrous oxide on the surface by 0.1-3 g/m<2> expressed in terms of Fe. At this time, the uniformity of the above ferrous oxide layer can be improved by applying, after the above degreasing and pickling, precoating with one or more elements among Ni, Co, Fe, and Cu by 2-70 mg/m<2> coating weight to at least one side of the steel sheet. After reducing annealing, this steel sheet is immersed into a molten zinc bath to undergo galvanizing and then heated, by which the galvanizing layer is alloyed with the base steel. By this method, the smooth alloying hot dip galvanized steel sheet suitable for automobile trim us and excellent in surface characteristics can be obtained.
