ABSTRACT:
In an automotive vehicle, a shift in speed position is suppressed by increasing a hysteresis amount in vehicle speed between an shift-up vehicle speed and a shift-down vehicle speed when a periodic variation in engine output is effected under the control of a slip control unit, or by inhibiting a downshift for a predetermined length of time during the periodic variation in engine output effected under the control of the slip control unit.
