摘要： A control device for an internal combustion engine includes an in-cylinder pressure detector, an output shaft torque calculator, a target torque calculator, an input torque parameter calculator, and a controller. The output shaft torque calculator is to calculate an output shaft torque of an output shaft of the internal combustion engine based on an in-cylinder pressure. The target torque calculator is to calculate a target torque of the output shaft torque. The input torque parameter calculator is to calculate an input torque parameter representing an input torque such that the output shaft torque becomes equal to the target torque using a feedback control algorithm which is based on a controlled object model which models a controlled object that receives the input torque parameter as input and produces the output shaft torque as output. The controller is to control the output shaft torque using the input torque parameter.

摘要： An ECU executes a program including the steps of calculating a correction coefficient K (1) having a value that is greater as an accelerator pedal position is greater, calculating a first throttle position (1) as a product of a reference value BSE (1) and the correction coefficient K (1), calculating a correction coefficient K (2) having a value that is greater as the accelerator pedal position is greater, and calculating a second throttle position (2) as a product of a reference value BSE (2) and the correction coefficient K (2). If the throttle position is equal to or higher than the first throttle position (1), a target position lower than a provisional target position set in accordance with the accelerator pedal position is set. If the throttle position is set to the second throttle position (2), the throttle position is maintained at the second throttle position (2).

摘要： An electronic throttle control apparatus can detect a motor open-circuit failure without detecting a motor current. A throttle opening sensor detects an actual throttle opening position (ATOP) of a throttle valve, and a throttle actuator serves to drive the throttle valve and hold the throttle valve at an intermediate opening stopper position (IOSP) during non-energization of the motor. The throttle actuator is feedback controlled such that the ATOP coincides with a target throttle opening position (TTOP). When the throttle valve continues, for a predetermined time, a state in which the absolute value of an opening position deviation between the ATOP and the IOSP is less than or equal to a first predetermined value, and in which the absolute value of a control deviation between the TTOP and the ATOP is larger than or equal to a second predetermined value, it is determined that the motor is in an open-circuit failure.

摘要： A throttle control system for controlling a throttle valve of an automotive internal combustion engine in order to securely accomplish a traction control. The throttle control system comprises a first throttle valve operated by an accelerator, and a second throttle valve controlled under the action of a control unit as follows: The fully closed position of the first throttle valve is learned as a first fully closed position corresponding value, when the first throttle valve is fully closed. The fully closed position of the second throttle valve is learned as a second fully closed position corresponding value under control of an actuator to compulsorily fully close the second throttle valve immediately after turning ON of a switch for allowing electric current to flow to the engine. A fast idle cam is provided to each of the first and second throttle valves to change the fully closed position of the first and second throttle valves larger in a direction to open each throttle valve as an engine temperature lowers to provide a change amount representative of a change in the first fully closed position corresponding value, under action of a thermally responsive member which is deformable in response to the engine temperature. The second fully closed position corresponding value of the second throttle valve is corrected in accordance with the change amount in the first fully closed position corresponding value, thereby controlling the opening degree at the fully closed position of the second throttle valve at a value suitable for the traction control.
