Abstract: An engine control system includes: a normalization module configured to normalize, to within a predetermined range of values, a spark timing of an engine and at least one other parameter of the engine, thereby producing a normalized spark timing and at least one normalized other parameter, respectively; a processing module configured to generate a sigmoidal spark timing by applying, to the normalized spark timing, one of (a) a sigmoidal function and a sinusoidal function; and an estimation module configured to estimate a torque output of the engine based on the normalized spark timing and the at least one normalized other parameter using a mathematical model.

Abstract: A fuel control module, based on an engine torque request, fuels N cylinders of an engine using a first fuel system. N is an integer greater than zero. A throttle control module, based on the engine torque request and the fueling of the N cylinders using the first fuel system, opens a throttle valve to a predetermined wide open throttle (WOT) position. A cost module, when the engine torque request is greater than a predetermined torque: determines a first cost value for fueling at least one of the N cylinders of the engine using a second fuel system; and determines a second cost value for adjusting at least one operating parameter other than fueling of the engine. An adjustment module, based on, the first and second cost values, one of: initiates the fueling of the at least one of the N cylinders using the second fuel system; and adjusts of the at least one operating parameter other than fueling of the engine.

Abstract translation: 基于发动机扭矩请求的燃料控制模块使用第一燃料系统对发动机的N个气缸进行燃料。 N是大于零的整数。 基于发动机转矩要求和使用第一燃料系统的N个汽缸的燃料供给的节气门控制模块将节流阀打开到预定的大开度节气门（WOT）位置。 当发动机扭矩要求大于预定扭矩时，成本模块：使用第二燃料系统确定用于燃料发动机的N个气缸中的至少一个的第一成本值; 并且确定用于调整除了发动机的燃料供给之外的至少一个操作参数的第二成本值。 基于第一和第二成本值的调节模块之一是：使用第二燃料系统启动N个气缸中的至少一个的燃料供给; 并且调整所述至少一个操作参数，而不是所述发动机的燃料加注。
