Patent number: 5537967Abstract: A vibration damping control system for an automotive vehicle is provided. This system includes a torque generator operating with given operation timing to produce a torque vibration of a preselected frequency and an operation timing controller. The operation timing controller initially determines a phase difference between engine revolution and frequency of vehicle vibration formed of a resultant vector defined by a first vibration component caused by movement of a crankshaft of the engine and a second vibration component caused by movement of a piston of the engine. The controller then modifies the operation timing of the torque generator to provide the torque vibration in an opposite phase relative to the vehicle vibration based on the phase difference determined to compensate the vehicle vibration.Type: GrantFiled: March 10, 1995Date of Patent: July 23, 1996Assignee: Nippondenso Co., Ltd.Inventors: Hiroshi Tashiro, Hiroyuki Aota, Takaji Murakawa, Toyoji Yagi, Shigenori Isomura

Patent number: 5497741Abstract: A torque control system for engines reduces electric power consumption by appropriately avoiding torque application after the engine starts increasing its torque output. The system detects the ignition timing of an engine and initiates motor mode operation of a motor-generator. The motor-generator continuously applies torque to number of ignitions which occur immediately before the engine torque actually starts increasing under the torque increase command, and then initiates generator operation of the motor-generator. Since the motor operation of the motor-generator terminates almost simultaneously with the increase in engine torque, there is no overlap between torque application by the motor-generator and increase torque output of the engine, and effective torque application and savings of battery power can be achieved.Type: GrantFiled: July 18, 1994Date of Patent: March 12, 1996Assignee: Nippondenso Co., Ltd.Inventors: Hiroshi Tashiro, Takaji Murakawa, Toyoji Yagi

Patent number: 5495127Abstract: Disclosed is an engine starting apparatus which suppresses engine vibrations and noises during engine cranking and reduces consumption of electric power supplied for engine cranking. When an engine starts to rotate to produce its torque, electric power supplied to a starter motor for engine cranking is reduced gradually so that a sum of torques produced by the starter motor and the engine may be prevented from increasing excessively. In the case a generator/motor is used for engine starting, operation of the generator/motor is switched from motor operation to generator operation for suppressing excessive speed rise when engine starting is completed.Type: GrantFiled: September 1, 1994Date of Patent: February 27, 1996Assignee: Nippondenso Co., Ltd.Inventors: Hiroyuki Aota, Hiroshi Tashiro, Takaji Murakawa, Toyoji Yagi

Patent number: 5469816Abstract: A control mechanism for an electric generator motor which can prevent excessive charging and insufficient capacity of an electrical power storage device includes a controller controlling operation of the electric generator motor when a total of restorable electrical power calculated on the basis of vehicle state and a present capacity of the electrical storage device is smaller than a specified reference capacity. The control mechanism effects a motor operation, i.e., application of torque, of the generator motor within a range in which the capacity of the electrical storage device does not fall below a specified minimum charge level required for driving vehicle auxiliary devices. The control mechanism effects motor operation of the electric generator motor with continuously changing restorable electrical power which has a positive correlation with an effective amount of depression of a brake pedal.Type: GrantFiled: September 1, 1994Date of Patent: November 28, 1995Assignee: Nippondenso Co., Ltd.Inventors: Takaji Murakawa, Toyoji Yagi, Hiroshi Tashiro

Patent number: 5415139Abstract: A system for controlling an excess air ratio of an internal combustion engine for an automotive vehicle is provided which includes a battery, a generator-motor, an air/fuel sensor, and a controller. The generator-motor is mechanically connected to the engine to establish transmission of torque therebetween, and operates in motor and generator modes. In the motor mode, the generator-motor serves as a motor to provide a given amount of torque to the engine under power supply of the battery. In the generator mode, the generator-motor works as a generator to convert engine torque into electric power for charging the battery. The air/fuel sensor determines an excess air ratio of the engine. The controller activates the generator-motor in the motor mode to control the amount of torque to be supplied to the engine based on the excess air ratio so that an air/fuel ratio falls within a preselected range suitable for purification of exhaust gas of the engine.Type: GrantFiled: September 1, 1994Date of Patent: May 16, 1995Assignee: Nippondenso Co., Ltd.Inventors: Hiroyuki Aoto, Hiroshi Tashiro
