An air conditioning device for a vehicle having a regenerative section improves efficiency of regeneration. The air conditioning device comprises a compressor () connected to an output shaft () of an engine () via an electromagnetic clutch (), a motor-generator () for electrically recovering kinetic energy of the vehicle () during deceleration, a battery () for storing energy regenerated by the motor-generator (), and a motor-driven compressor (). When the vehicle () is in a deceleration state, the compressor () is disconnected from the engine () by disengaging the electromagnetic clutch (), and air conditioning is performed by the motor-driven compressor ().

Air conditioning device for vehicle

The catalyst warming control apparatus of the present invention is provided for a hybrid vehicle having an internal combustion engine, a generator for generating electric power from the output from the internal combustion engine, a power storage unit for storing electric power generated by the generator, and an electric motor driven by the electric power stored in the power storage unit, the hybrid vehicle being driven by at least one of the outputs from the internal combustion engine and the motor. The catalyst warming control apparatus includes a temperature detector for detecting the temperature of a catalyst or a value relating to the same; a first comparison circuit for comparing the detected result from the temperature detector with a preset reference value; and a control circuit for allowing the generator to generate electric power and to store the power in the power storage unit when the internal combustion engine is driven, and when the detected result by the temperature detector is equal to or below the reference value according to the output from the comparison circuit.

Catalyst warming control-apparatus

A control device for a hybrid vehicle, the hybrid vehicle comprising an engine and a motor as power sources, the control device including: a battery device sending energy to and receiving energy from the motor, a temperature sensor for measuring the temperature of the battery device; a control section which is adapted to execute a warming control operation for the battery device when the temperature of the battery device is low; and a determination section for determining whether a cylinder deactivation operation is permitted for the engine depending on the running state of the engine. The control section executes a vibration control operation for the engine by operating the motor so as to reduce vibration of the engine when it is determined by the determination section that the partial cylinder deactivation operation is permitted for the engine, and to perform the warming control operation for the battery device by executing a vibration control operation for the engine.

Control device for hybrid vehicle

In order to improve the fuel consumption efficiency of a hybrid vehicle, a control apparatusfor a hybrid vehicle is provided, which comprises as a power source a motor M and an engine E capable of executing partial cylinder deactivation operation and the driving force of at least one of these is transmitted to wheels for running the vehicle. When the required output is larger than the output of the engine under partial cylinder deactivation operation, and is smaller than the total output of the engine and the motor, which is adjustable for assisting the engine, the control apparatus operates the engine under partial deactivation and adjusts the motor output so as to compensate the difference between the total output of the power source and the output of the partial cylinder deactivated engine.

Control apparatus for hybrid vehicle

A hybrid vehicle includes: a metal V-belt type infinitely variable gear-change mechanism whereby the rotation of an engine E is subjected to change in gear ratio, a forwards clutch and a reverse brake that perform engagement/disengagement control of the engine and the infinitely variable gear-change mechanism, and a second motor generator capable of driving the drive wheels arranged parallel with the engine. The control device is provided with a first hydraulic pump for engine drive, a second hydraulic pump that is driven by an electric motor for pump drive, and a forwards/reverse clutch control valve that performs changeover control of supply of working hydraulic pressure to the forwards clutch etc. When vehicle running is performed with the engine stopped, the forwards clutch etc is disengaged by the forwards/reverse clutch control valve, and the second hydraulic pump is driven by the electric motor for pump drive, gear-change control of the infinitely variable gear-change mechanism being performed in accordance with the current driving conditions by using this hydraulic pressure.

Hybrid vehicle control device

The hybrid vehicle of the present invention has an internal combustion engine, a power storage unit for storing electric power, and a motor driven by the electric power stored in the power storage unit, the hybrid vehicle being driven by at least one of the outputs from the internal combustion engine and the motor. The drive power control apparatus comprises: a detector for detecting variations in torque produced by the internal combustion engine; a converter for converting the variation into an output from the motor, based on the detection result of the detector; a remaining charge detector for detecting remaining charge of the power storage unit or a value relating to the same; a comparison circuit for comparing the detection result from the remaining charge detector with a preset remaining charge reference value or a value relating to the same; and a controller for driving the motor, based on the output from the converter, when warming up the catalyst by retarding the ignition timing of the internal combustion engine, and when it is determined, based on the output from the comparison circuit, that the detection result from the remaining charge detector is equal to or above the remaining charge reference value or the value relating to the same.
