摘要： An electronic throttle valve control system prevents rapid rotation of a throttle valve when the control system has a failure. A throttle valve controls the amount of intake air to an internal combustion engine, an electric motor drives the throttle valve, and a control section controls the electric motor. The throttle valve has an urging mechanism for urging the throttle valve in the closing direction. The control section shifts the electric motor to a regenerative mode when the control system has a failure to control the speed at which the throttle valve is rotated in the closing direction by the urging force of the urging mechanism. The throttle valve is therefore rotated slowly in the closing direction by the urging force of the urging mechanism and then held in a predetermined opening position.

摘要： [Problem] To provide an electronic throttle valve control system which can prevent rapid rotation of a throttle valve when the control system has a failure. [Solution] There are provided a throttle valve 10 for controlling the amount of intake air to an internal combustion engine, an electric motor 20 for driving the throttle valve 10, and a control section 21 for controlling the electric motor 20. The throttle valve has an urging mechanism 31 for urging the throttle valve 10 in the closing direction. The control section 21 shifts the electric motor 20 to a regenerative mode when the control system has a failure to control the speed at which the throttle valve 10 is rotated in the closing direction by the urging force of the urging mechanism 30. The throttle valve 10 is therefore rotated slowly in the closing direction by the urging force of the urging mechanism 30 and then held in a predetermined opening position 10b.

摘要： An abnormality monitoring device monitors a PWM driving signal output from a driving section of an associated motor control system to judge whether the driving section is operating abnormally. By monitoring the output of the driving section, the monitoring device can detect an abnormality of the driving section before the motor can respond to the abnormal drive signal to a significant degree (e.g., to a degree readily discernable to a rider of a motorcycle on which the motor control system is employed in combination with an electronic throttle system).

摘要： An electronic engine control unit for a motorcycle or other two-wheeled vehicle gradually decreases engine torque at the time of a failure so as to eliminate an uneasy feeling that an operator might experience if the engine torque were to be reduced abruptly. When a failure is detected, a throttle valve is closed gradually by initially closing the valve quickly and then slowly closing the valve so as to obtain a smooth decrease in engine torque. In addition, the ignition timing is changed gradually toward retardation to gradually decrease engine torque. Alternatively, the ignition pulses to the cylinders are thinned out gradually to cause a gradual decrease in engine torque. As a further alternative in the case of a multi-cylinder engine, the ignition pulses are stopped on a cylinder-by-cylinder basis to cause a gradual decrease in engine torque.
