Control apparatus for vehicle plant

Abstract:

A control apparatus for a vehicle plant, which is capable of reducing computational load and a storage capacity in a case where the vehicle plant is controlled using a plurality of periodic function values having a plurality of frequencies different from each other. A control apparatus for a fuel cell device includes a first ECU and a second ECU. The second ECU calculates superposition sine wave value of one of frequencies Z to nZ (Hz) based on a frequency command value by a thinning method using a data group of one set of reference sine wave values, stored in a map. The second ECU executes an AC superposition control using the superposition sine wave value, and calculates impedance of the fuel cell device during execution of the AC superposition control. The first ECU executes fuel cell (FC) humidification control process such that the impedance becomes equal to a target value.
