MACHINE COMPONENT IN AUTOMOBILE, AND SYSTEM FOR PREDICTING BEHAVIOR OF AUTOMOBILE

摘要

PPROBLEM TO BE SOLVED: To report a safety level including the degree of risk of the occurrence of a slip in an automobile to a driver by predicting the behavior of the automobile at the time of braking, driving, and turning of the automobile. PSOLUTION: Machine components 12, such as a tire 14 and a shock absorber 16 in an automobile, having dinamic properties braking/driving drive characteristics, cornering characteristics, and the like, for characterizing the braking performance, driving performance, and turning performance of the automobile have IC tags 14c, 16c having memories 14a, 16a for storing the characteristic information of the dynamic characteristics. A vehicle traveling safety alarming system 10 comprises the machine components 12; a communication device 22 for acquiring the characteristic information of the machine components stored in the memories 14a, 16a; and an arithmetic unit 28 for predicting the lengthwise acceleration and crosswise acceleration of the limit of the automobile by using the characteristic information obtained by the communication device 22. The percentage of allowance of the lengthwise acceleration and crosswise acceleration of the current automobile is calculated for reporting for safe driving. PCOPYRIGHT: (C)2005,JPO&NCIPI
