DEVICE FOR CONTROLLING VEHICLE DRIVE UNIT

摘要

A control apparatus for a vehicle drive unit is provided to achieve demands related to various capabilities of the vehicle drive unit appropriately without allowing an operational load of a computer to be increased. The control apparatus includes a control structure of a hierarchical type having a demand generation level 10, a mediation level 20, and a control variable setting level 30 and a signal is transmitted in one direction from a higher level of hierarchy to a lower level of hierarchy. The demand generation level 10 includes demand output elements 12, 14, and 16 for each capability, the demand output elements 12, 14, and 16 outputting numerical values that represent the demands related to the various capabilities. The mediation level 20 includes mediation elements 22, 24, and 26, each corresponding to a classified category of demands. Each of the mediation elements 22, 24, and 26 collects demand values of the category of which the mediation elements 22, 24, and 26 are in charge and performs mediation according to a rule to arrive at a single demand value. The control variable setting level 30 includes an adjuster portion 32 adjusting each of the mediated demand values based on a relationship between each other and control variable calculation elements 34, 36, and 38 calculating a control variable of each of a plurality of actuators 42, 44, and 46 based on the adjusted demand value.
