Apparatus for estimating vehicle tire air pressure from not only tired wheel motion but also tire temperature

摘要

An apparatus for estimating an air pressure of a tire (26) of a tired wheel (14) of a motor vehicle, on the basis of a temperature of the tire as well as a motion of the tired wheel, preferably including a temperature-related variable sensor (70, 92, 102, 122) for detecting a temperature-related variable (t) related to the temperature of the tire, and an estimating device (52, 56, 58, 60, 62, 64, 82, 84, 86, 88, 90, 96, 100, 106, 120, 126) for estimating the air pressure of the tire on the basis of the temperature-related variable as well as the motion of the tired wheel.
