    • A method of determining throttle flow in a fuel delivery system is disclosed. First, a time-efficient throttle flow data collection method is described. The collection method uses a sonic nozzle flow bench to measure airflow as a function of throttle angle and pressure in a manner analogous to on-engine dynamometer throttle flow characterization. Opening each sonic nozzle combination, then recording throttle downstream pressure and computed nozzle flow allows data to be taken in a fraction of the time normally needed. In conventional methods, the estimated airflow rate as a function of throttle angle differs from the measured airflow rate because the leak area is incorrect. The method of the invention correctly determines the estimated throttle airflow rate by using a low pass filtering technique to adjust the estimated airflow rate to eventually equal the measured airflow rate, particularly at small throttle angles.
    • 公开了一种确定燃油输送系统中的节流流量的方法。 首先,描述了一种节省时间的节流流量数据收集方法。 收集方法使用声波喷嘴流动台以类似于发动机功率计油门流量表征的方式测量作为节气门角度和压力的函数的气流。 打开每个声波喷嘴组合,然后记录节气门下游压力和计算喷嘴流量允许在通常需要的时间的一小部分中拍摄数据。 在常规方法中,作为节流角的函数的估计气流速率与测量的气流速率不同,因为泄漏区域不正确。 本发明的方法通过使用低通滤波技术来正确地确定估计的节气门气流速率,以调整估计的气流速率,以最终等于所测量的气流速率,特别是在小节气门角度。

    • A throttle control apparatus and method is disclosed in a vehicle having a throttle valve with a default position intermediate a fully-closed position and a fully-open position, and a spring mechanism coupled to the throttle valve that creates torque to move the throttle valve toward the default position in the absence of other torque. The throttle control apparatus includes an actuator for generating torque to open and close the throttle valve in response to a control signal, wherein the actuator is attached to the throttle valve by a mechanical coupling having lash. The throttle control apparatus also includes a processor in communication with the actuator, the processor generating the control signal based upon a command signal. The processor executes a stored program including a portion to compare a new value of the command signal with a prior value of the command signal, and to generate the control signal as a function of the deviation between the new and prior values of the command signal.

    • An electronic throttle control system is described where a throttle position sensor has multiple slopes depending on the operating region. At low throttle positions, a greater slope, and thus a greater sensitivity is provided, thereby increasing control resolution. At greater throttle positions, a lower slope, and thus lower sensitivity is provided. In this way, an output signal that varies across the entire operating region of the throttle is provided for monitoring and control, while improved performance at low throttle angles can be simultaneously achieved. A method for learning a transition region is also desribed.
    • 描述了一种电子节气门控制系统,其中节气门位置传感器具有取决于操作区域的多个斜率。 在低油门位置,提供更大的斜率,从而提供更大的灵敏度,从而增加控制分辨率。 在较大的节气门位置,提供较低的斜率,从而提供较低的灵敏度。 以这种方式,在节气门的整个操作区域上变化的输出信号被提供用于监视和控制,同时可以同时实现在低节气门角度下的改进的性能。 还描述了一种学习过渡区域的方法。
