Patent number: 5111784Abstract: An apparatus induces vibrations in a generator for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. The load torque of a generator fixed to the engine is changed to generate an angle moment on the body of the generator to cancel engine vibrations due to rough idling and suppress body vibrations due to the rough idling. Irregular combustion of the engine is detected from a change in the engine speed, and a voltage higher than the output voltage of the generator is than applied across the field winding to increase the field winding current and hence the load torque on the generator, which induces vibrations on the generator body. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled.Type: GrantFiled: February 1, 1991Date of Patent: May 12, 1992Assignees: Hitachi, Ltd., Nissan Motor Co., Ltd.Inventors: Shigeru Kuriyama, Yuji Maeda, Yozo Nakamura, Kenichi Nakamura, Keiichi Mashino, Yuzo Kadomukai, Masao Fukushima, Kei Murakami

Patent number: 5109815Abstract: A method of reducing vibrations of a car body comprises a step of detection of rough which is irregular combustion in an engine, preferably through monitoring of angular velocity of a crankshaft of the engine, and a step of exerting such external force as will cancel roll vibrations of the engine caused by the rough on an engine block of the engine temporarily after the occurrence of the rough. A magnitude of the force and timing of exerting the force is preferably determined on the basis of a degree of the rough and the angular velocity immediately before the occurrence of the rough.Type: GrantFiled: January 28, 1991Date of Patent: May 5, 1992Assignees: Hitachi, Ltd., Nissan Motor Co., Ltd.Inventors: Yuuji Maeda, Yozo Nakamura, Kenichi Nakamura, Masahide Sakamoto, Yuzo Kadomukai, Masao Fukushima, Kei Murakami

Patent number: 5087869Abstract: The present invention relates to an electrical protective circuit, used when abnormality occurs, in a vibration suppressing apparatus which changes the load torque on a generator such as an alternator fixed on the engine to generate an angle moment on the generator body to cancel rough idling engine vibrations to suppress vehicle body vibrations due to the rough idling. In the inventive vibration suppressing apparatus, a generator is fixed on the engine which generator includes a voltage regulator to control a field winding current such that a fixed voltage is output to a battery. The generation of engine rough idling is detected on the basis of either a change in the engine speed or a change in the engine vibrations. If rough idling is detected, a high voltage circuit is connected to the field winding to increase the field winding current and hence the load torque on the generator.Type: GrantFiled: January 25, 1991Date of Patent: February 11, 1992Assignees: Hitachi, Ltd., Nissan Motor Co. Ltd.Inventors: Shigeru Kuriyama, Yozo Nakamura, Yuji Maeda, Kenichi Nakamura, Keiichi Mashino, Yuzo Kadomukai, Masao Fukushima, Kei Murakami

Patent number: 5083038Abstract: In a vehicle vibration reduction control apparatus for controlling an alternator driven by an engine to charge a battery in such a way that vehicle body vibration due to the engine can be cancelled by alternator vibration, the reference voltage applied to an alternator field coil is reduced by a predetermined value for a predetermined time period, whenever battery terminal voltage exceeds a predetermined level. Since the battery charging rate can be reduced automatically at battery overcharge due to cancellation of engine vibration by alternator vibration, it is possible to prevent the battery from being overcharged when engine vibration increases at idling, for instance.Type: GrantFiled: January 17, 1991Date of Patent: January 21, 1992Assignee: Nissan Motor Company, Ltd.Inventors: Masao Fukushima, Kei Murakami, Shigeru Kuriyama, Yozo Nakamura, Yuji Maeda, Kenichi Nakamura, Keiichi Mashino, Yuzo Kadomukai

Patent number: 5056487Abstract: For example, while the state of combustion of an internal combustion engine is detected from a cylinder pressure at the top dead center of the cylinders, if a decision has been made that the detected combustion state is an irregular combustion state, on the basis of a result of comparison between a torque waveform corresponding to the irregular combustion state and a torque waveform under normal combustion state, this torque control apparatus for internal combustion engines according to this invention puts into operation a torque correcting device, such as a motor-generator, mounted fixedly to the internal combustion engine, thereby making the former torque waveform approach the latter torque waveform. Therefore, even when an irregular combustion occurs in the internal combustion engine, the torque waveform is substantially free from irregularity, so that vibration and an abnormal noise can be prevented.Type: GrantFiled: August 31, 1990Date of Patent: October 15, 1991Assignees: Hitachi, Ltd., Nissan Motor Co., Ltd.Inventors: Makoto Yamakado, Yuzo Kadomukai, Ryoichi Maeda, Masao Fukushima, Kei Murakami
