The present disclosure relates to a method for avoiding overheating of a vehicle subsystem (14) comprising a compressor (16) with a pressure chamber (16A). The method comprises the steps of executing an extended Kalman filter on the control module (18) to calculate an error between a predicted state model of the vehicle subsystem (14) and a corresponding measured state model of the vehicle subsystem (14); and processing the calculated error to adjust the predicted state model based on the weighted uncertainty of the measured parameter and the estimated parameter, including adjusting the estimated ambient pressure. The method further comprises the steps of: comparing the estimated ambient pressure to a predetermined ambient pressure default; and when the estimated ambient pressure is less than or equal to the predetermined ambient pressure default value, reducing the cut-off pressure target value of the vehicle subsystem (14) by a reduction amount over a period of time.

    本公开涉及一种用于避免车辆子系统(14)过热的方法,所述车辆子系统包括带压力室(16A)的压缩机(16)。所述方法包括以下步骤:在控制模块(18)上执行扩展卡尔曼滤波器,以计算车辆子系统(14)的预测状态模型与车辆子系统(14)的对应测量状态模型之间的误差;并且处理所计算误差以基于所测量参数和所估计参数的加权不确定性调整预测状态模型,包括调整估计环境压力。所述方法进一步包括以下步骤:将估计环境压力与预定环境压力默认值进行比较;以及当估计环境压力小于或等于预定环境压力默认值时,在一段时间内将车辆子系统(14)的截止压力目标值减小一个减小量。
