AUTOMOBILE STRUCTURAL MEMBER FAILURE PROBABILITY COMPUTING METHOD, MEMORY ELEMENT AND CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an automobile structural member failure probability computing method for accurately obtaining a failure probability of a structural element of an automobile. SOLUTION: During drive of the structural element 1, a form data of an influence parameter (pr) for giving an influence to the failure probability (PA) of the structural element 1 as an important cause of damage is detected for storage. In order to obtain the failure probability, a load group as the influence quantity important to proof driving strength of the structural element 1 is obtained. So as to accurately obtain the failure probability (PA) based on the real load group, the influence parameter (pr) is analyzed and evaluated in a control device 9 for the automobile during drive of the structural element 1 to obtain the failure probability (PA).
