VEHICLE CONTROLLER

PROBLEM TO BE SOLVED: To provide a vehicle controller capable of controlling a driving state of auxiliary machinery such as an oil pump, a compressor or the like properly and improving energy efficiency. SOLUTION: This vehicle controller includes a main power source 1 for generating driving force for vehicle, an auxiliary power source 2 capable of being operated independently from the main power source 1, the auxiliary machinery 3 being rotated and driven by power from the outside to perform the predetermined operation, and a planetary gear mechanism 4 having three rotational elements including an input element 4r, a reaction force element 4s, and an output element 4c which connects the main power source 1, the auxiliary power source 2, and the auxiliary machinery 3 mutually to transmit power each to control a rotating state of the auxiliary machinery 3. This vehicle controller includes a demanded work amount detection means (step S1) for detecting amount of work demanded for the auxiliary machinery 3 and differential adjustment means (steps S2, S4) for increasing or decreasing amount of differential between at least any two rotational elements based on the amount of work detected by the demanded work amount detection means.
