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.
