摘要： The invention provides an apparatus and a method of estimating tire air pressure with high accuracy from vehicle operation at low at high speeds regardless of various elements to be mounted to the vehicle. Estimation of tire air pressure based on a resonance frequency extracted based on a wheel speed signal outputted from a wheel speed sensor corresponding to the respective tire and estimation of tire air pressure based on a dynamic load radius derived based on the wheel speed signal, are used to selectively switch in accordance with a magnitude of a variance value of the resonance frequency at a plurality of time points.

摘要： A pressure based mass flow controller that can be used, for example, in semiconductor manufacturing for precisely delivering a process vapor to a process chamber. The controller can be used with a low vapor pressure source, and has a simplified, novel design, that allows the controller to be easily and inexpensively incorporated in a system including a plurality of such controllers and a plurality of vapor sources. The controller includes a flow path for connection to a vapor source, a flow restrictor dividing the flow path into an upstream reservoir and a downstream reservoir, an upstream pressure measurement device connected to the upstream reservoir, and a flow valve connected to the flow path. The controller also includes a control device programmed to receive a desired flow rate, an indication of upstream pressure from the upstream pressure measurement device, an indication of downstream pressure from a remote downstream pressure measurement device connected to the downstream reservoir. The control device then determines an actual mass flow rate during choked flow conditions in accordance with a linear function of the upstream pressure, and during non-choked flow conditions in accordance with a nonlinear function of the upstream pressure and the downstream pressure. The control device is also programmed to instruct the flow valve to increase flow if the actual flow rate is less than the desired flow rate, and to decrease flow if the actual flow rate is greater than the desired flow rate.

摘要： Method for Monitoring an Electrohydraulic Braking System Indications of the enrichment of brake fluid with air are obtained from the comparison of the volume uptake of the wheel brakes at a specific wheel brake pressure with an evaluation threshold in a p/v diagram. The volume uptake is determined by the elasticity within the wheel brake that is subjected to certain fluctuations, on the one hand, and to a much greater degree by the clearance that is present, on the other hand. To make a reliable statement relating to the air charge, an estimation of the current clearance is first made, taking three ranges into consideration. If there is a very large clearance, no monitoring takes place, rather attempts are made to reduce the clearance by an active clearance limitation. If there is a normal clearance, a top evaluation threshold is taken as a basis, which assumes the clearance lies at the upper end of the normal range. When said evaluation threshold is exceeded, an alarm is triggered. If the clearance is assumed to lie at the bottom limit of the normal range, a bottom evaluation threshold applies, however, an alarm is only triggered in this case if this situation has occurred several times in succession.

摘要翻译： 监控电动液压制动系统的方法通过比较在特定车轮制动压力下的车轮制动器的体积吸收与p / v图中的评估阈值，可以获得用空气浓缩制动液的指示。 另一方面，体积吸收由一方面受到一定波动的车轮制动器内的弹性和另一方面存在的间隙的更大程度决定。 作出与空运费用有关的可靠陈述，首先对当前清关进行了估计，考虑了三个范围。 如果存在非常大的间隙，则不进行监视，而是尝试通过主动间隙限制来减小间隙。 如果存在正常的间隙，则以顶部评估阈值为基础，假设间隙位于正常范围的上限。 当超过所述评估阈值时，触发报警。 如果将间隙设置在正常范围的下限，则应用底部评估阈值，但是，如果此情况连续发生数次，则仅在此情况下触发报警。
