    Abstract: An engine control system and method includes sensing the quality of fuel in the engine relative to emissions, by for example sensing the level of an emission related constituent, such as sulfur. A fuel quality sensor detects a fuel quality of a fuel, such as the sulfur level the fuel, and provides a signal in response to the fuel quality. The engine control system also includes a navigation device to determine whether an engine is located in a regulated or non-regulated region. The engine control system receives the signal and controls engine operation by, for example, enabling or disabling one or more engine algorithms to improve performance of the engine based on the fuel quality signal or, in other embodiments, the combination of the fuel quality and the location of the engine.

    Abstract: A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.

    Abstract translation: 速度曲线可以与车辆操作条件数据一起使用，以确定减速计划，以减轻通过优化使用发动机转速，摩擦和发动机制动来减慢车辆所需的行车制动力量。 换挡点将发动机驱动到更高的运行速度和更大的摩擦力矩，从而使车辆减速，然后可以将其转到所需的速度。 换档点可以定时，以最小化机动时的燃油消耗。 因此，基于传动装置推荐来创建车辆降档事件。 这样做的好处是通过最大限度地减少燃料消耗和维持驾驶性能来提高货物运输从源头到目的地的运输效率。
