description The invention provides a vehicle fault diagnosis method and device, a vehicle and a program product, and relates to the technical field of vehicles. According to the method and the device, weighting processing can be carried out on the vehicle parameter characteristics related to the faults based on the fault description information of the vehicle faults, so that the comprehensive vector characteristics of the vehicle faults are determined, the target historical faults similar to the comprehensive vector characteristics are determined from the historical fault database, and corresponding fault solving measures are executed. Therefore, each vehicle parameter feature determines the comprehensive vector feature based on the weight of the vehicle parameter feature and the vehicle fault (fault description information), thereby reflecting the nonlinear correlation between the fault and each vehicle parameter feature in the actual fault, and improving the characterization capability of the comprehensive vector featu
