A system for controlling idle speed and power draw has a unit (4) for determining a current available power value, a unit (5) for determining a current power consumption value, a unit (6) for determining a future power demand change value, a unit (7) for calculating a future total power demand estimate, a unit (8) for calculating a future available power estimate, and a unit (7) for calculating a future total power demand change value. An optimization unit (9) that determines an optimization result by comparing the total power demand estimate with a power value associated with an optimization criterion, and a control unit (17) that outputs a command to adapt the engine idle speed, a command to adapt the total power demand estimate, or does not issue a command according to the optimization result. 用于控制怠速速度和功率汲取的系统具有用于确定当前可用功率值的单元(4)、用于确定当前功率消耗值的单元(5)、用于确定未来功率需求变化值的单元(6)、用于计算未来总功率需求估计值的单元(7)、用于计算未来可用功率估计值的单元(8)、通过将总功率需求估计值与和优化标准相关联的功率值进行比较来确定优化结果的优化单元(9)、以及根据优化结果输出适配发动机怠速的命令、适配总功率需求估计值的命令或不发出命令的控制单元(17)。
