<p><P>PROBLEM TO BE SOLVED: To further improve a method for monitoring a wheel characteristic amount and a monitoring device and to constitute the monitoring device so as to detect no response of the monitoring device or a wheel electronic circuit even if feeding of energy is dependent on traveling dynamic data. <P>SOLUTION: The characteristic amount (2) is read and transmitted to an evaluation unit (40) at the time (32) when energy required for transmission is provided by the energy feed part (25). The presumption transmission timing (30) is calculated by the evaluation unit (40) by using at least one traveling dynamic parameter (50) and a model of the energy feed part (25) filed in a data memory unit (44) of the evaluation unit (40). The presumption transmission timing (30) is compared with actual transmission timing (32) and when deviation or lack of transmission between the presumption transmission timing (30) and the actual transmission timing (32) is detected, an alarm signal is outputted. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
