    • A throttle valve control system for an internal combustion engine installed in a vehicle. A throttle valve opening sensor detects an actual opening of a throttle valve, and an ECU calculates a desired opening of the throttle valve according to the rotational speed of the engine and the required torque of the engine, which is calculated according to operating conditions of the engine and operating conditions of the vehicle, and electrically controls the throttle valve such that the detected actual opening of the throttle valve becomes equal to the desired opening of the throttle valve. An intake pressure sensor detects actual intake pressure within the intake passage, and desired intake pressure within the intake passage is calculated according to the rotational speed of the engine and the required torque of the engine. The desired intake pressure is compared with the detected actual intake pressure, and the desired opening of the throttle valve is corrected based on results of the comparison.
    • 一种用于安装在车辆中的内燃机的节气门控制系统。 节流阀开度传感器检测节气门的实际开度,并且ECU根据发动机的转速和发动机的所需转矩来计算节气门的期望开度,该转矩是根据发动机的运转条件 发动机和操作条件,并且电控制节流阀,使得所检测到的节气门的实际开度变得等于节气门的所需开度。 进气压力传感器检测进气通道内的实际进气压力,并且根据发动机的转速和发动机的所需转矩来计算进气通道内的所需进气压力。 将所需的进气压力与检测到的实际进气压力进行比较,并根据比较结果校正节气门的所需开度。

    • A control system provided in a hybrid vehicle with a combustion engine for outputting a driving force, an electric motor for generating a force for assisting the output from the engine, depending on driving conditions, a power storage unit for storing electric energy generated by the motor acting as a generator using the output from the engine and electric energy regenerated by the motor when the vehicle decelerates. The control system includes an output assist determination means for determining, based on a determination threshold value as the standard, whether to assist the output from the engine by the motor, depending on the driving conditions of the vehicle. An air-fuel controller is provided for changing the air-fuel ratio of the mixture, which is to be supplied to the engine, to a condition leaner or richer than the stoichiometric air-fuel ratio. A determination threshold value changing means is provided for changing the determination threshold value, depending on whether the air-fuel ratio of the mixture is leaner or richer than the stoichiometric air-fuel ratio. A determination threshold value change prohibiting means is provided for prohibiting the operation of the determination threshold value changer when the air-fuel controller changes the air-fuel ratio of the mixture from a condition leaner than the stoichiometric air-fuel ratio to a condition richer than the stoichiometric air-fuel ratio.
