Automobile road reliability test design method

The invention discloses an automobile road reliability test design method, which comprises the following steps of: simulating a user working condition by using a sample automobile or a competing automobile, and collecting acceleration data; data processing is carried out on the user working condition acceleration data, and GRUBBS inspection is carried out; using a sample vehicle or a competitive vehicle to collect acceleration data under a test working condition; carrying out data processing on the test working condition acceleration data, and carrying out GRUBBS inspection; calculating a comprehensive fatigue damage rate corresponding to each test pavement according to the user working condition and the test working condition acceleration data; determining the distribution proportion of the test pavement; and calculating the comprehensive conversion fatigue multiplying power of the user working condition and the corresponding pavement test mileage. According to the automobile road reliability test design met
