Abstract

A control apparatus for a vehicle drive unit including a control structure of a hierarchical type having a demand generation level, a mediation level, and a control variable setting level and a signal is transmitted in one direction from a higher level of hierarchy to a lower level of hierarchy. The demand generation level includes demand output elements for each capability. The mediation level includes mediation elements, each corresponding to a classified category of demands. Each of the mediation elements collects demand values of the category of which the mediation elements are in charge and performs mediation according to a rule to arrive at a single demand value. The control variable setting level includes an adjuster portion adjusting each of the mediated demand values based on a relationship between each other and control variable calculation elements calculating a control variable of each of a plurality of actuators based on the adjusted demand value.
