摘要： At an actual engine rotary speed corresponding to a partially engaged state of a starting clutch, a target gear ratio control of a continuously variable transmission is performed by determining a target gear ratio from a target engine rotary speed. At an actual engine rotary speed corresponding to an engaged state of the starting clutch, the gear ratio is controlled in a manner such that the actual engine rotary speed converges with a target engine rotary speed. Accordingly, when it is intended to start the vehicle with a comparatively large throttle opening, it is possible, at the partially engaged condition, to obviate a rise in the actual engine rotary speed with the gear ratio position sticking to a desired position, so that a predetermined driving force is attained when the starting clutch is engaged.

摘要： A flow controlling method for an auxiliary intake flow passage for use in a power unit which includes a starter clutch which is automatically engaged and disengaged in response to the engine speed. An intake air control valve (IACV) carries out changeover from water temperature dependent control (open loop control of adjusting the flow rate of the auxiliary intake flow passage in response to the warming up state of an engine) to target engine speed feedback control when the actual engine speed NE [rpm] drops to a clutch disengagement engine speed NEout (engine speed at which the centrifugal clutch is disengaged) (S3: Yes) and the opening θ1 [degree] of the throttle valve becomes smaller than a predetermined threshold value (throttle valve opening threshold value TH—θ1 (S4: Yes).

摘要： A control method for a hydraulic type continuously variable transmission for suppressing a harmful effect due to the reacceleration just after deceleration of a vehicle. In a hydraulic type continuously variable transmission, the operation of a shifting actuator is stopped to suspend the shift control (S7) when a throttle valve is rapidly opened just after fully closed (S4: Yes) and an engine speed NE [rpm] is being rapidly increased (S6: Yes). Accordingly, even when the actual engine speed NE becomes much greater than a target engine speed T_NE during reacceleration just after deceleration of a vehicle, unexpected shift control (upshifting) can be prevented, so that more desirable torque can be produced.

摘要： The degradation of a feeling of ride is prevented by preventing engagement/disengagement (sudden engagement/disengagement) of a motorcycle hydraulic clutch due to a lack of hydraulic pressure. Before a hydraulic sensor issues a hydraulic pressure-lowering detection signal Sx, an oil level sensor issues an oil level-lowering warning signal Sf in a state wherein a sufficient oil quantity is such so as not to bring an neutral drive switching clutch into a disengagement state is present even if hydraulic pressure lowers resulting from an inclined oil level due to sudden deceleration, sudden start, drive in a slope, or the like. Thus, the neutral drive switching clutch can be prevented from disengaging or engaging (suddenly disengaging or engaging).

摘要： A transmission control method for a continuously variable transmission for enhancing the response of a change in engine speed to a driver's accelerating/decelerating operation. In a hydraulic type continuously variable transmission, when a sport operating mode is being selected (step S1: SPORT OPERATING MODE), a target engine speed T_NE (rpm) is calculated from the vehicle velocity V (km/hr) and the position θ (degrees) of a throttle valve 60 (step S4). Further, a target angle T_A (degrees) for a motor swash plate is calculated from the vehicle velocity and the target engine speed T_NE (step S5). The motor swash plate is moved according to the difference between the actual angle A of the motor swash plate 46 and the target angle T_A.

摘要： To detect opening/closing of a neutral detection hydraulic switch by a detection apparatus and detect breakage of a wiring line connected between the detection apparatus and the switch. Since a second contact and an ECU are connected to each other by two wiring lines, even if one of the wiring lines is broken, opening/closing of the neutral detection hydraulic switch can be detected through the remaining one of the wiring lines. Since different voltages are applied to the wiring lines through resistance type voltage dividing circuits, the occurrence of the wire breakage can be detected making use of the fact that the voltage detected by the ECU upon opening of the neutral detection hydraulic switch when one of the wiring lines is broken is different from the voltage when none of the wiring lines is broken.

摘要： An engine control system and an engine control method for improving the ability to start an engine by changing the execution timings of predetermined sumchecks in ROM to shorten the time required for initialization of the system. Upon starting an ECU with a power supply supplied from an AC generator as a result of an operation of a kick starter, a CPU initialization, which includes a hardware reset and a software initialization, is executed. An ignition timing calculation sumcheck, which is required for the calculation of an ignition timing, and injection timing calculation sumcheck, which is required for the calculation of an injection timing, are not executed in a period of the software initialization. Instead, they are executed during BG (background) processing after a movement to routine processing, which upon completion of the software initialization, starts the ECU to permit driving and controlling an igniter and a fuel injector.

摘要： A motor vehicle includes an engine and an external setting unit configured to set an engine control amount. A control unit is configured to store a basic control map having a preset engine control amount contained therein. The control unit is also configured to communicate with the external setting unit. An engine setting system is configured to change the preset engine control amount by replacing the preset engine control amount with the engine control amount set by the external setting unit. The engine control amount set by the external setting unit is reflected in the basic control map. The engine control amount set by the external setting unit is reflected in the control map when a start preparing operation is detected.
