    摘要: To execute a manual speed change to apply an engine brake in good response, and to ensure sufficient braking force in a drive unit having a continuously variable speed change unit and a geared speed change unit.For this purpose, a control system for a drive unit of a vehicle, in which a speed change mode can be selected from a first speed change mode wherein a total speed change ratio governed by the speed change ratio of the continuously variable speed change unit and the gear stage of the geared speed change unit is set on the basis of a running condition of a vehicle, and a second speed change mode wherein the total speed change ratio is set on the basis of a signal for applying a power source braking comprises: a gear stage limiting means for reducing number of gear stages of the geared speed change unit settable under the second speed change mode smaller than that under the first speed change mode; and wherein the total speed change ratio is set according to the gear stage of the geared speed change unit set by the gear stage limiting means, and to the speed change ratio of the continuously variable speed change unit, in case the second speed change mode is selected.
