摘要： 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.
摘要翻译：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。

摘要： Systems and methods are provided for monitoring reverse flow of fuel vapors and/or air through a vehicle fuel vapor recovery system, said fuel vapor recovery system coupled to an engine intake of a boosted internal combustion engine. One example method comprises, intermittently adjusting a restriction in the fuel vapor recovery system during boosted conditions, and indicating degradation based on one or more of a change in a pressure value, or based on a change in flow in the fuel vapor recovery system.

摘要： A method for providing intake air to an engine in a vehicle comprises delivering compressed fresh air and EGR to the engine via first and second throttle valves coupled to an intake manifold of the engine. During a higher engine-load condition, an EGR exhaust flow is cooled in a heat exchanger and the cooled EGR exhaust flow is admitting to the intake manifold. During a lower engine-load condition, fresh air is warmed in the heat exchanger, and the warmed fresh air is admitted to the intake manifold.
