    • A method, computer program product and apparatus for estimating the pneumatic pressure of a tire on a vehicle, comprising the steps of: receiving as an input a vehicle status sensor signal; estimating first parameter values of an adaptive filter based on a predetermined model on the vehicle status dependent on the vehicle status sensor signal; calculating, dependent on said first model parameter values, a first tire pressure indication value (δ) being dependent on and indicative of the pneumatic pressure of the tire. Specifically, the vehicle status signal may be an input a wheel angular velocity signal (1) and a lateral movement indication signal; the adaptive filter is based on a predetermined model on lateral vehicle dynamics dependent on the angular velocity of said wheel and the lateral movement of said vehicle.
    • 一种用于估计车辆上的轮胎的气压的方法,计算机程序产品和装置,包括以下步骤:接收车辆状态传感器信号作为输入; 基于取决于车辆状态传感器信号的车辆状态上的预定模型来估计自适应滤波器的第一参数值; 根据所述第一模型参数值计算依赖于并指示轮胎气动压力的第一轮胎压力指示值(delta)。 具体地,车辆状态信号可以是车轮角速度信号(1)和横向移动指示信号的输入; 自适应滤波器基于取决于所述车轮的角速度和所述车辆的横向运动的侧向车辆动力学的预定模型。
