    • An engine control microprocessor transient interrupt system is provided wherein an engine throttle position sensor provides a throttle position input signal to a microprocessor which developes engine control output signals in response thereto. The throttle position sensor also provides an input signal to a transient detector external to the microprocessor which provides an interrupt signal to the microprocessor in response to the rate of change of throttle position exceeding a threshold. In response to the interrupt signal, the microprocessor provides a disable signal which disables the external transient detector, and then the microprocessor monitors the rate of change of engine throttle position to determine the end of the throttle position transient condition and enables the external transient detector in response to the end of the transient condition.
    • 提供了一种发动机控制微处理器瞬态中断系统,其中发动机节气门位置传感器向微处理器提供节气门位置输入信号,微处理器响应于微处理器开发发动机控制输出信号。 节气门位置传感器还向微处理器外部的瞬态检测器提供输入信号,其响应于节气门位置的变化率超过阈值而向微处理器提供中断信号。 响应于中断信号,微处理器提供禁用外部瞬态检测器的禁用信号,然后微处理器监视发动机节气门位置的变化率,以确定节气门位置瞬变状态的结束,并使外部瞬态检测器 对瞬态状态的响应。
