Abstract: A vehicle control apparatus includes an engine and a motor generator, and controls a hybrid vehicle in which the engine is started by starting torque outputted from the motor generator. The apparatus includes a prestart control section which makes the motor generator output prestart torque smaller than the starting torque before the engine is started by the starting torque, a balance determination section which determines whether or not compression torque caused by pressure in a cylinder of the engine and the prestart torque are balanced with each other, and a start-up control section which makes the motor generator output the starting torque, after the balance determination section determines that the compression torque and the prestart torque are balanced with each other.

Abstract: A control apparatus is applied to a system including an engine and a compressor for air-conditioning, and adjusts an operating point of the engine when the engine is operated. The control apparatus determines whether or not to allow increase in engine output to drive a compressor based on an air-conditioning request, based on the operating point of the engine before driving of the compressor in relation to a predetermined high-efficiency region including a maximum efficiency point in an efficiency characteristics of the engine, when the compressor is driven in response to the air-conditioning request. The control apparatus controls the engine output such that the operating point of the engine is in the high-efficiency region, if the increase in engine output is determined to be allowed.
