摘要： The throttle valve controller 1 includes a failure detecting device 11 for detecting failures in the first and second accelerator sensors 2 and 3 based on the first input signal VAPS1 outputted from the first accelerator sensor 2 and the second input signal VAPS2 outputted from the second accelerator sensor 3. A control signal computing device 12 computes a first control signal T1 from the first and second input signals in response to the result of detection by the failure detecting device 11. A control signal correcting device effects primary delay processing on the first control signal T1, thereafter restricting the so-processed signal to a guard value or less and outputs the signal therefrom as a second control signal VAPS. A throttle control device 14 controls the degree of opening of the throttle valve 9 based on the second control signal VAPS.

摘要： A throttle valve controller achieves high output response to the smaller deviation of the actual opening from the demand opening of the throttle valve and achieves high control stability against the larger deviation. It has a preset data table containing proportional gain values and integral gain values of PID control in correspondence to deviation values in inversely proportional arrangement. During the transitional state of control system, a pair of provisional gain values are read out of the table in response to the deviation value: (step S3), these gain values are compared with those of the previous operation cycle and the smaller gain value pair are selected: (steps S4-S7), and the valve drive signal is calculated from the selected gain values:(steps S8, S11). Consequently, the controller achieves high output response to the smaller deviation due to the larger gain value and high control stability without the overshooting of valve movement against the larger deviation due to the smaller gain value.
摘要翻译： 节气门控制器实现了对实际开度与节流阀需求开度的较小偏差的高输出响应，并且对较大的偏差实现了高的控制稳定性。 它具有预设的数据表，其中包含比例增益值和PID控制的积分增益值对应于反比例排列的偏差值。 在控制系统的过渡状态期间，响应于偏差值从表中读出一对临时增益值：（步骤S3），将这些增益值与先前操作周期和较小增益值对进行比较 （步骤S4-S7），根据所选择的增益值计算出阀驱动信号：（步骤S8，S11）。 因此，由于较大的增益值和较高的控制稳定性，控制器对较小的偏差产生较高的输出响应，而不会由于较小的增益值而导致阀运动过大而导致较大的偏差。

摘要： An electromagnetic PCV valve includes a valve seat, a valve element, a step motor for moving the valve element, and a housing that houses the valve seat, the valve element, and the step motor. When the valve element is moved by the step motor, a size (an opening degree) of a blow-by gas passage defined between the valve seat and the valve element is changed. The step motor is configured to selectively receive energization for moving the valve element and energization for holding the valve element in a fixed position. A heating apparatus of the PCV valve 1 includes a cover member and an output shaft that conducts heat generated in the step motor by energization to the valve element and the valve seat, and an electronic control unit (ECU) for conducting energization of the step motor to hold the valve element in the fixed position.

摘要： A throttle control apparatus comprises a throttle valve placed in an intake passage, a motor for driving the throttle valve, an electronic control unit (ECU) for controlling the motor, and a throttle sensor for detecting an actual opening degree of the throttle valve. The ECU determines that the throttle valve is frozen when the actual opening degree does not reach a target opening degree even after a driving time for driving the motor has exceeded a predetermined time, and then stores the actual opening degree at the time as an icing opening degree. The ECU supplies a driving duty to cause the motor to produce required driving torque for removal of icing and reverses the driving duty by open control, and controls the motor to bring an accumulated value of a deviation between the target opening degree and the icing opening degree to zero, thereby repeatedly swinging the throttle valve.

摘要： An electronic throttle control apparatus is provided with an electronic throttle (1) including a throttle valve (4) which is opened and closed by a motor (5), and a microcomputer (11) which controls the motor (5). The microcomputer (11) calculates a deviation between a target opening degree which is set by detection of an accelerator sensor (5) and an actual opening degree which is detected by a throttle sensor (6) to calculate a motor control amount in accordance with the deviation and a control gain in correspondence to the deviation. The microcomputer 11 sets a control gain which becomes smaller as the deviation becomes larger, and limits the control gain by the previous control gain at a time when the control gain is larger than the previous control gain. The microcomputer (11) cancels the limit of the control gain when the calculated actual opening degree change is reduced from a predetermined value.

摘要： A controller for a step motor which permits the actual step number of the step motor to properly follow up the target step number may be varied with time. The controller temporarily determines a duration shorter than an actually derived duration, and checks the target step number again when the temporarily determined duration has elapsed. If the target step number has not changed, the actually derived duration is considered as a finally determined duration, while, if the target step number has changed, the duration of energization is re-derived from the changed target step number.
