    • An integrated throttle control and idle validation sensor includes mechanically coupled but electrically independent throttle control and idle validation components. A single mechanical input to the protective sensor housing corresponds to an accelerator pedal position and causes selective coupling of a supply voltage to one of an idle validation conductor and a throttle validation conductor for interpretation by an electronic control system. The throttle control system within the sensor housing comprises a potentiometer adapted for movement corresponding to the mechanical input whereby a variable voltage throttle control signal may be delivered to the electronic fuel control system. The sensor integrates previous separate throttle control and idle validation functions into a single environmentally secure housing and requires no calibration. The disclosed throttle system is more reliable and less costly than previously available separate throttle control and idle validation functions.
    • 集成的节气门控制和空闲验证传感器包括机械耦合但电独立的节气门控制和空闲验证部件。 保护传感器壳体的单个机械输入对应于加速器踏板位置,并且使电源电压选择性地耦合到空闲验证导体和用于由电子控制系统解释的节气门确认导体之一。 传感器外壳内的节气门控制系统包括适于与机械输入对应的移动的电位器,由此可将电压调节控制信号传送到电子燃料控制系统。 该传感器将先前的单独的节气门控制和空闲验证功能集成到单个环境安全的外壳中,无需校准。 所公开的节气门系统比先前可用的单独的节气门控制和空闲验证功能更可靠,成本更低。
