Abstract:
1. A control apparatus for a vehicle drive unit achieving demands related to various types of capabilities of the vehicle drive unit by coordinately controlling a plurality of actuators related to operations of the vehicle drive unit, the control apparatus having a control structure of a hierarchical type, the control structure comprising: a demand generation level; a mediation level disposed on a level lower than the demand generation level; and a control variable setting level disposed on a level lower than the mediation level, signals being transmitted in one direction from a higher level of hierarchy to a lower level of hierarchy, wherein: the demand generation level includes multiple demand output elements, each of which is associated with any one of the various types of capabilities of the vehicle drive unit, and outputs one or more demands related to an associated type of capability, each of the demands falling into any one of predetermined multiple demand categories, the mediation level includes multiple mediation elements, each of which is assigned to a single demand category among the predetermined multiple demand categories, and collects the one or more demands falling into an assigned category, and mediates the collected one or more demands into a single demand according to a predetermined rule, and the control variable setting level includes an adjuster portion adjusting the values of mediated demands based on a relationship between the mediated demands, and includes multiple control variable calculation elements, each of which is assigned to a single actuator among the plurality of actuators, and calculates a control variable of an assigned actuator based on at least one of the mediated demands and adjusted demands, each of the mediated demands and the adjusted demands being used to calculate at least one control variable of the plurality of actuators.
