    • A Vehicle Disturbance Estimator determines estimates of a vehicle disturbance force according to vehicle operating conditions. The determined vehicle disturbance force estimate can be used, for example, in connection with controlling a cruise control system for the vehicle, in connection with fuel economy evaluations and testing, and in connection with vehicle diagnostics. A plurality of sets of inputs can be used to determine plural vehicle disturbance estimates for time periods during which a cruise control is on, the vehicle is being driven in the highest gear, and the vehicle is not being braked by any brakes. The plurality of vehicle disturbance estimates can be averaged to provide an output corresponding to an average vehicle disturbance estimate over a plurality of sampling time periods. Kalman filtering can be used to determine the vehicle disturbance estimates. Signals corresponding to the plural disturbance estimates can be provided as an input to a cruise control, with the cruise control then being operable to control the speed of the motor vehicle, based at least in part upon the vehicle disturbance estimate.
    • 车辆扰动估计器根据车辆操作条件确定车辆扰动力的估计值。 确定的车辆扰动力估计可以用于例如结合燃料经济性评估和测试以及与车辆诊断相结合来控制车辆的巡航控制系统。 可以使用多组输入来确定巡航控制开启的时间段,车辆以最高档进行驾驶,并且车辆没有被制动器制动的时间段的多个车辆干扰估计。 可以对多个车辆干扰估计进行平均以提供对应于多个采样时间段中的平均车辆干扰估计的输出。 卡尔曼滤波可用于确定车辆扰动估计。 可以将与多个干扰估计相对应的信号提供给巡航控制的输入,其中巡航控制然后可操作以至少部分地基于车辆干扰估计来控制机动车辆的速度。
