Abstract
PURPOSE:To prevent the occurrence of a new speed-change shock at the time of returning from a speed-change shock reducing control to a coasting control by delaying the return in accordance with the type of a return condition and the traveling condition of a vehicle at the time of returning. CONSTITUTION:When the coasting condition of a vehicle is detected, a coasting time control means for automatically shifting a speed change stage according to the previously set change point of a speed change map varies at least the down-shift point out of the speed change points of the speed change map to be high to the extent that a speed change command is issued prior to a condition for an engine output to drive a vehicle, to reduce a speed-change shock. When the establishment of a return condition from this special control is detected by a detecting means, a return delaying time setting means delays the return for a defined time in accordance with at least one of the type of the established return condition and the traveling condition of a vehicle at the time of returning. Thereby, the occurrence of a new speed-change shock due to returning can be prevented.
