  • Patent number: 7516730
    Abstract: In a fuel pump control system for an internal combustion engine whose operation is switched between cut-off-cylinder operating mode during which some of the cylinders are non-operative and full-cylinder operating mode during which all of the cylinders are operative and having a fuel injector connected to the fuel supply line and supplied with fuel pressurized by the fuel pump, it is discriminated whether the operation of the engine is in the full-cylinder operating mode or in the cut-off-cylinder operating mode, the operation of the fuel pump is controlled based on the discriminated operating mode of the engine, i.e., is controlled such that the delivery flow rate of the fuel pump when the engine is discriminated to be in the cut-off-cylinder operating mode, is reduced relative to that when the engine is discriminated to be in the full-cylinder operating mode, thereby reducing the power consumption and operating noise of the fuel pump.

  • Patent number: 7143596
    Abstract: 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 (1a) 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).

  • Patent number: 7099757
    Abstract: An FI/AT/MGECU, in a cylinders deactivation operating state during cruise control where the vehicle speed follows a predetermined target speed, regulates renewal on an addition side of a power plant required torque final value TQPPRQF, and in a case where a flag value of a torque hold flag F_CCKTQS showing to hold the power plant required torque final value TQPPRQF to a predetermined torque value related to a cylinder deactivation upper limit torque TQACS is a “1” (YES side in step S33), when the vehicle speed VP is decreased less than a value obtained by subtracting from a set vehicle speed VC which is the target vehicle speed during cruise control, a predetermined vehicle speed #?V (for example, #?V=3 km/h or the like) (YES side in step S35), the internal-combustion engine E is switched from a cylinders deactivation operation to an all cylinders operation. The fuel consumption efficiency is thus improved while keeping occupants in the vehicle from feeling discomfort with respect to travelling behavior.
