An air conditioner for a vehicle includes a main heater for heating air in a vehicle compartment using coolant of an engine of the vehicle as a heat source, and an auxiliary heater for heating air in the vehicle compartment using a heat source other than exhaust heat of the engine. In the air conditioner, a requirement signal for requiring startup of the engine is output when a temperature of the coolant of the engine is determined to be lower than a threshold, and the threshold is adjusted based on an operating state of the auxiliary heater such that as an amount of heat generated by the auxiliary heater increases, the threshold decreases. Accordingly, as the heating capacity of the auxiliary heater is increased, the startup of the engine becomes more difficult.

In a control unit of a hydraulic control device, a workload calculation unit calculates the amount of workload cut in a first pump when supply of first oil from the first pump to a continuously variable transmission mechanism through a check valve is switched to supply of second oil from a second pump to the continuously variable transmission mechanism. A workload determination unit determines whether the amount of workload loss of an ACG is more than the amount of workload cut. A motor controller stops a motor or decreases a rotation number if the workload determination unit determines that the amount of workload loss is more than the amount of workload cut.

In a control apparatus mounted in a vehicle supporting start-stop control, for controlling a power supply system, a target charge level setter variably sets a target charge level of a second rechargeable battery when an internal-combustion engine of the vehicle is operating.
