CONTROLLER FOR VEHICLE

PROBLEM TO BE SOLVED: To change operation conditions of a vehicle for an atmospheric pressure without using any atmospheric pressure sensor. SOLUTION: This control system 100 of a hybrid car comprises: a driving device 10 including an engine 12, a first rotary motor 14, a second rotary motor 15, and a planetary gear mechanism 16; a power source circuit 20; and a controller 40 for vehicle. A CPU 42 of the controller 40 for vehicle comprises: an engine operation point calculation module 50 for calculating an engine operation point under a standard atmospheric pressure; an actual engine torque calculation module 52 for calculating actual engine torque based on first rotary motor output or second rotary motor output; an atmospheric air estimation module 54 for comparing the calculated actual engine torque with the engine torque of the engine operation point under the standard atmospheric pressure, and for estimating the actual atmospheric pressure; and a power source circuit operation condition decision module 56 for determining the power source operation conditions according to the estimated atmospheric pressure.
