Disclosed are a cloud terminal-based vehicle remote diagnosis method, server end, vehicle end and client end. The vehicle remote diagnosis method comprises the steps that the diagnosis information ofa vehicle is received, the diagnosis information of the vehicle is analyzed, and diagnosis and debugging data are extracted from the diagnosis information of the vehicle, and the diagnosis and debugging data are stored; operation request data of a mobile terminal is received, the operation request data of the mobile terminal is analyzed, operation attribute information is extracted, and configuration and diagnosis data are obtained from the diagnosis and debugging data according to the operation attribute information; and a vehicle state report is generated according to the configuration and diagnosis data, and the vehicle state report is sent. By virtue of the vehicle remote diagnosis method, the technical problems of low expansibility of vehicle-mounted equipment caused by poor effect, low whole vehicle diagnosis operation efficiency, relatively low remote operation information safety, low diagnosis operation interactivity and over-high coupling degree of a diagnosis system, and relatively poor flexibility caused by single system architecture in the prior art are solved.
