摘要： In a refrigerant cycle system having a hot gas heater function, a valve device includes a solenoid valve for opening and closing a communication between a compressor and a condenser, a differential pressure valve opened by a pressure difference between a discharge side of the compressor and an inlet side of the condenser when the solenoid valve is closed for directly introducing gas refrigerant from the discharge side of the compressor into an evaporator, and a check valve for preventing refrigerant discharged from the compressor from flowing into the condenser when the solenoid valve is opened. In the valve device, at least the three valves are integrated by a housing member to construct an integrated member.

摘要： A switch valve is provided in a refrigerant circuit. The switch valve includes a first valve mechanism, a second valve mechanism, and a single valve housing incorporating the first and second valve mechanisms. The first valve mechanism is an electromagnetic valve. The first valve mechanism selectively connects and disconnects an outlet of a compressor with an inlet of a condenser in accordance with an electric current supply. The second valve mechanism is a differential pressure valve. The second valve mechanism selectively connects and disconnects the outlet of the compressor with an inlet of an evaporator in accordance with a difference between the pressure at the outlet of the compressor and the pressure at the inlet of the condenser. In this manner, the single switch valve, which includes the first and second valve mechanisms incorporated in the same valve housing, switches the refrigerant circuit between a path for a cooling operation and a path for a warming operation. This structure simplifies the configuration of the refrigerant circuit.

摘要： A valve timing control is executed by an ECU that controls an engine and an electric-motor ECU that controls an electric motor. The ECU and the electric-motor EDU serve different functions. The ECU sets the target phase of an intake valve based on the engine operating state, and prepares a rotational speed command value for the electric motor that serves as an actuator such that a phase feedback control loop, in which the intake valve phase is caused to match the target phase, is formed. The electric-motor EDU forms a feedback control loop for the motor speed, in which the electric power supplied to the electric motor is controlled such that the electric motor rotates in accordance with the rotational speed command value.

摘要： An ECU transmits a pulsed operation command signal, indicating operation commands for an electric motor used as a VVT actuator, to an electric-motor EDU. The electric-motor EDU recognizes the combination of the direction in which the actuator should be operated (actuator operation direction) and the control mode based on the duty ratio of the operation command signal, and the rotational speed command value based on the frequency of the operation command signal. The electric-motor EDU controls the electric motor according to the control commands. The duty ratio indicating the combination is set such that even if the duty ratio is falsely recognized, a false recognition concerning the actuator operation direction is prevented, such false recognition causing the valve phase to change in an undesirable direction, and even if the actuator operation direction is falsely recognized, the rate of change in the phase is restricted.

摘要： In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

摘要： During the period of deceleration of a vehicle, an air conditioning control unit modifies a target cooling temperature (TEO) of an evaporator to a temperature lower than that before the deceleration by γ ° C. in order to store cold in the evaporator (step S130). When the vehicle comes to rest, the air conditioning control unit sets an upwardly-modified target temperature TEOK, which is a temperature modified toward more or less higher temperatures from the target cooling temperature TEO, and brings a compressor to rest and keeps the resting state of the compressor until a detected temperature TE of an evaporator discharge temperature sensor exceeds TEOK (step S180). Therefore, it is possible to effectively utilize the cold heat stored in the evaporator 6 during the period of deceleration of the vehicle with a good feeling of passengers being maintained while the vehicle is at rest.
