摘要:
An air conditioning device for a vehicle having a regenerative section improves efficiency of regeneration. The air conditioning device comprises a compressor ( 6 ) connected to an output shaft ( 1 a) of an engine ( 1 ) via an electromagnetic clutch ( 5 ), a motor-generator ( 2 ) for electrically recovering kinetic energy of the vehicle ( 100 ) during deceleration, a battery ( 9 ) for storing energy regenerated by the motor-generator ( 2 ), and a motor-driven compressor ( 13 ). When the vehicle ( 100 ) is in a deceleration state, the compressor ( 6 ) is disconnected from the engine ( 1 ) by disengaging the electromagnetic clutch ( 5 ), and air conditioning is performed by the motor-driven compressor ( 13 ).
摘要:
A control device of a hybrid drive vehicle comprising an internal combustion engine and a power generating motor as a driving source for vehicle, wherein, immediately after it is detected that an air/fuel ratio of air/fuel mixture supplied to the engine is changed to lean side (S44 to S46), the power generating motor (2) is operated as a motor (S47, S48) in order to assist an output from the engine and, immediately after it is detected that an air/fuel ratio of air/fuel mixture supplied to the engine is changed to rich side (S44, S52, S53), the power generating motor (2) is operated as a generator (S54, S55) in order to apply regenerative braking to the engine, whereby a difference in output torque from the engine produced when the air/fuel ratio of the supplied air/fuel mixture is varied can be compensated for sufficiently without delay.
摘要:
A failure detection device for a vehicle having a deceleration deactivatable engine, by which failure detection, performed primarily by monitoring the oil pressure of operation oil, is ensured. The failure detection device is provided for a vehicle having a deceleration deactivatable engine in which it is possible to deactivate at least one cylinder by closing both of intake and exhaust valves thereof by applying the oil pressure of operation oil to a passage for deactivation execution via an actuator, and also it is possible to cancel the closed state of both of the intake and exhaust valves by applying the oil pressure of the operation oil to a passage for deactivation cancellation. The failure detection device includes an oil pressure condition judgement section (steps S204 and S212) which determines whether the oil pressure of the operation oil measured by a POIL sensor satisfies threshold conditions, and an abnormality judgement section (steps S207 and S215) which determines that abnormality exists when it is determined, by the oil pressure condition judgement section, that the oil pressure of the operation oil does not satisfy the threshold conditions.
