    摘要: 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. In the inventive protective circuit, the battery voltage is compared with a predetermined reference value when no rough idling is detected. If the battery voltage exceeds the reference value, a changeover signal is generated and the high voltage circuit is disconnected from the field winding in response to the changeover signal.

    摘要: 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.

    摘要: An apparatus and a method for detecting abnormal combustion in an internal combustion engine and an apparatus and a method for controlling vibration caused by abnormal combustion. The apparatus for detecting abnormal combustion includes a unit for detecting the rotation of an internal combustion engine, a unit for calculating rotation angular acceleration on the basis of the detected rotation, a unit for comparing the rotation angular acceleration at the position of a predetermined crank angle in one cycle of the operation of the internal combustion engine with a predetermined reference value, and a unit for judging from the comparison result whether abnormal combustion occurs in the internal combustion engine. The apparatus for reducing vibration caused by abnormal combustion offsets vibration caused by abnormal combustion and vibration of an electric generator to each other by passing a pulse-like field current in the electric generator in response to detection of abnormal combustion to generate vibration torque in the electric generator.

    摘要: A state of a plurality of switches for performing application and cutoff of a plurality of electrical loads is stored in a memory circuit. A pattern of supply power after application of the load for each of the plurality of electrical loads and a load response priority order assigned previously to each of the electrical loads are stored in a memory table. A control circuit identifies a newly applied load on the basis of the turned-on state of the plurality of switches stored in the memory circuit and instructs an electric power supply circuit to supply electric power in accordance with the supply power pattern corresponding to the identified load, while the control circuit prohibits application of the newly applied electrical load when an electrical load having the load response priority order higher than that of the newly applied electrical load has been already applied. The memory table may store consumption power and an application priority order assigned previously to each of the electrical loads. In this case, a total amount of consumption power of the applied electrical loads is calculated. When an electrical load having the application priority order lower than that of the newly applied electrical load has been already applied and the control circuit judges that the total amount of consumption power of the applied electrical loads exceeds a predetermined value, the control circuit instructs to cut off the electrical load having the lower application priority order.
