摘要： The present technology provides one or more methods of operating an engine in a motor vehicle. In at least one embodiment, the existence of an engine idle condition is determined. The method may also include determining whether an operator is present in the vehicle. In some embodiments, the engine operates at a performance idle speed when an engine idle condition exists and an operator is present in the vehicle. In further embodiments, the engine operates at a fuel economy idle speed when an idle condition exists and no operator is present in the vehicle. In still further embodiments, the fuel economy idle speed will be lower than the performance idle speed. The present technology anticipates engine workload and controls engine idle speeds. Based on the anticipated workloads, the present technology can reduce engine stalling while also reducing emissions and increasing fuel economy.

摘要翻译： 本技术提供在机动车辆中操作发动机的一种或多种方法。 在至少一个实施例中，确定发动机空转条件的存在。 该方法还可以包括确定操作者是否存在于车辆中。 在一些实施例中，当发动机空转条件存在并且操作者存在于车辆中时，发动机以性能怠速运转。 在另外的实施例中，当空转状态存在并且车辆中没有操作者时，发动机以燃料经济性怠速运转。 在另外的实施例中，燃料经济性怠速将低于性能空转速度。 本技术预计发动机工作量并控制发动机空转速度。 根据预期的工作量，本技术可以减少发动机停滞，同时减少排放和提高燃油经济性。
