20100242908 | ENGINE IGNITION CONTROL APPARATUS - When cranking starts by turning on a starter switch | 09-30-2010 |
20100242909 | KNOCK CONTROL DEVICE FOR ENGINE - Embodiments of the invention provide that an ignition is retarded when continuously occurring knocks are detected, while an ignition is not retarded when a singly occurring knock is detected. | 09-30-2010 |
20100250094 | ENGINE THROTTLE CONTROL SYSTEM - An operation amount detecting unit | 09-30-2010 |
20120016569 | FUEL INJECTION CONTROL SYSTEM - A fuel injection control system provided with a throttle by wire (TBW) system detecting an operation condition of a throttle grip and controlling, via an actuator, a throttle valve. The control system detects the throttle valve opening and controls an injector. An increased quantity correction value is determined based upon of an output of a throttle valve opening sensor and an operation condition of the throttle grip. When an acceleration condition of a vehicle is detected according to the output of the throttle valve opening sensor, an increased quantity correction of fuel is performed. The increased quantity correction value is brought to an attenuation condition in which the increased quantity correction value is gradually decreased, or a stop condition in which the increased quantity correction value is made to zero, when the throttle grip is not in drive in an opening direction, even though an acceleration condition is detected. | 01-19-2012 |
20120323467 | FUEL INJECTION AMOUNT CALCULATION METHOD AND FUEL INJECTION CONTROLLING APPARATUS - A fuel injection amount calculation method calculates a fuel injection amount to an internal combustion engine of a vehicle. The method can include calculating a relative intake pressure which is a difference between an intake pressure peak of intake air upon intake starting of a cylinder of the internal combustion engine and an intake pressure bottom of the intake air upon intake ending. The method can also include calculating the fuel injection amount based on the relative intake pressure. | 12-20-2012 |
20130002418 | ENGINE ROTATIONAL SPEED DISPLAY DEVICE - An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is “0,” and the engine rotational speed of “0” is displayed on the meter. | 01-03-2013 |
20130008244 | DEVICE AND METHOD FOR OIL PRESSURE SENSOR FAULT SENSING FOR VEHICLE - A fault sensing device for a vehicle includes a time measuring section functioning as a sleep mode while power to a controller is off. The time measuring section can measure a stop time of an engine, and can transmit information on the stop time to the controller when power to the controller is on. When the controller determines that a stop time of the engine is a predetermined time, the controller performs fault sensing for an oil pressure switch. | 01-10-2013 |
20130133457 | SHIFT CONTROL DEVICE FOR MOTORCYCLE, AND MOTORCYCLE INCORPORATING SAME - A shift control device for a motorcycle includes a transmission that allows switching between a neutral state and a number of engaged shift positions, a shift control section that controls a shift state of the transmission, and an N/D changeover switch that switches between the neutral state and a drive mode for executing automatic shift among the plural shift positions. The shift control device also includes a hand-operated shift switch that allows manual shifting among the plural shift positions, and a foot operated shift control unit that allows manual shifting among the plural shift positions during the drive mode according to an operation of a shift pedal. The N/D changeover switch and the hand-operated shift switch are arranged around a handlebar of the motorcycle. The shift control section is operable to switch between the neutral state and the drive mode by the foot operated shift control unit. | 05-30-2013 |
