Autoadaptive engine idle speed control
A machine engine idle speed control system may include an automated autoadaptive mode to supplement typical economy and normal power modes. The autoadaptive mode may afford an operator with an automated option to optimize fuel economy and lower engine/machine noise. The autoadaptive mode may initially default to a typical lower engine idle speed of the economy mode. However, as the machine workload rises, demands on the engine may become greater, and at a predetermined threshold of engine workload the engine idle speed may be automatically increased to a higher set point. The engine control may then remain at the higher idle speed until engine load is reduced to some predetermined target, and/or after a certain time period has elapsed. The time period may be controlled by a configurable delay timer to avoid unnecessary/undesirable cycling between modes. In addition, an operator may always intervene to increase or decrease engine idle speed.
