Patent number: 7143596Abstract: 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).Type: GrantFiled: April 21, 2003Date of Patent: December 5, 2006Assignee: Honda Motor Co.

Patent number: 7099757Abstract: 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.Type: GrantFiled: July 2, 2004Date of Patent: August 29, 2006Assignee: Honda Motor Co., Ltd.Inventors: Manabu Niki, Masanobu Asakawa, Kohei Hanada, Minoru Suzuki, Teruo Wakashiro, Takahiro Yonekura, Naoto Sen
