Patent number: 6895908Abstract: A method and apparatus that permits engine system control such as exhaust valve timing without the use of separate load sensors from the output of a single engine timing sensor.Type: GrantFiled: May 23, 2003Date of Patent: May 24, 2005Assignee: Kabushiki Kaisha MoricInventors: Naoya Isoda, Yoshiyuki Nagatsu
-
Patent number: 6892702Abstract: A number of embodiments of improved engine system control method and apparatus based on operator demand and rate of change in demand that reduce not only the number of components but also decrease the complexity of the electronic system without requiring a throttle position sensor.Type: GrantFiled: May 23, 2003Date of Patent: May 17, 2005Assignee: Kabushiki Kaisha MoricInventors: Naoya Isoda, Yoshiyuki Nagatsu

Patent number: 6832598Abstract: A method and apparatus that permit anti-knock control without the use of separate knock detectors as well as controlling the basic ignition timing from the output of a single engine speed sensor.Type: GrantFiled: May 23, 2003Date of Patent: December 21, 2004Assignee: Kabushiki Kaisha MoricInventors: Naoya Isoda, Yoshiyuki Nagatsu

Patent number: 6742502Abstract: An improved method and system for the control of an engine system such as the spark timing. The control senses the speed variations either during a portion of a complete cycle and a complete cycle and/or from cycle to cycle in order to determine the load on the engine from preprogrammed maps based upon the engine characteristics. From this load and the speed reading, it is possible to obtain the desired engine control. In addition the timing is set in this method only under certain specified conditions and only in response to certain specific parameters. This not only reduces the costs of the system by reducing the number of sensors, but also permits adjustments to be made more rapidly.Type: GrantFiled: April 2, 2003Date of Patent: June 1, 2004Assignee: Kabushiki Kaisha MoricInventors: Yoshiyuki Nagatsu, Naoya Isoda

Patent number: 6683391Abstract: A method and apparatus of vehicle theft prevention, which utilizes a key having a transponder bearing an ID and a key cylinder, that is adapted to receive this key and which has an antenna for supplying electrical power to the transponder and receiving an ID signal back from it. This system permits easy correction of incorrectly set original IDs or the simple substitution of a new key or an old master key as a new master key into a vehicle wherein the lock cylinder must be replaced due to a defect. Also there is provided a holding circuit for permitting continued operation of the prime mover until the recognized key is shut off regardless of the condition of the controller.Type: GrantFiled: August 9, 2000Date of Patent: January 27, 2004Assignee: Kabushiki Kaisha MoricInventors: Masahiko Enoyoshi, Masayuki Yamamoto, Naoya Isoda

Publication number: 20030029419Abstract: Two embodiments of engine speed control that avoid undesirable vehicle conditions such as wheel slippage or unintentionally performing a wheelie. This is done by sensing actual conditions, which are likely to result in the undesirable vehicle conditions and only changing the engine output when these exact conditions are found. The conditions sensed are the determination of excessive acceleration in engine speed or in the speed of a shaft associated with the engine or the degree of rotational variation or rotational acceleration.Type: ApplicationFiled: July 23, 2002Publication date: February 13, 2003Inventors: Naoya Isoda, Masahiko Enoyoshi
