A method, an apparatus, and a computer program product are provided for estimating tread wear of a tire on a wheel of a vehicle. The tread wear indicates a difference between a starting tread depth and a current tread depth. The method includes obtaining a first angular velocity sensor signal indicative of an angular velocity of at least one first wheel or axle of the vehicle and a second angular velocity sensor signal indicative of an angular velocity of at least one second wheel or axle of the vehicle, respectively. The method further includes determining a tread wear difference based on the obtained angular velocity sensor signal, the tread wear difference indicating a tread wear difference between a tire at the first wheel or axle and a tire at the second wheel or axle. The method further includes estimating a first tread wear estimate for the first wheel or axle based on the determined tread wear difference and based on the estimated relationship.

    提供了用于估计车辆车轮上的轮胎的胎面磨损的方法、装置和计算机程序产品。胎面磨损指示起始胎面深度和当前胎面深度之间的差异。该方法包括获得分别指示车辆的至少一个第一车轮或车轴的角速度的第一角速度传感器信号和指示车辆的至少一个第二车轮或车轴的角速度的第二角速度传感器信号。该方法还包括基于所获得的角速度传感器信号确定胎面磨损差值,该胎面磨损差值指示第一车轮或车轴处的轮胎与第二车轮或车轴处的轮胎之间的胎面磨损差异。该方法还包括基于所确定的胎面磨损差值和基于估计的关系来估计第一车轮或车轴的第一胎面磨损估计值。
