Abstract

The invention discloses an integration testing method for analyzing the energy flow of a finished automobile. The method comprises the steps of installing a testing element of a power transmission system, installing a cooling system, an air conditioning system, a gas exhaust piping, a lubricating system, and a testing element for testing the network of an electric appliance, installing testing elements for a passenger compartment and an engine compartment, creating a testing environment, and testing and recording the real-time parameters of the above subsystems, wherein the cooling system, the air conditioning system, the gas exhaust pipe, the lubricating system and the testing element for testing the network of the electric appliance are connected with an engine. By the testing method, the real-time parameters of various subsystems of the same automobile under the same environment and working conditions are recorded, and the requirements of the analysis of energy flow of the finished automobile on the real-time parameters of the various subsystems are met.

Description

technical field [0001] The invention relates to a vehicle testing method, in particular to an integrated testing method for energy flow analysis of a complete vehicle. Background technique [0002] The energy flow analysis of the whole vehicle is to analyze the energy consumption of each subsystem and each component from the perspective of the whole vehicle, and obtain the energy consumption distribution map from fuel to wheels. The establishment of a vehicle energy flow analysis platform can use fast and low-cost control strategy optimization to achieve the purpose of reducing vehicle fuel consumption. In order to analyze the energy flow of the vehicle, it is necessary to collect real-time working state parameters of each subsystem related to energy consumption. Due to the coupling relationship between the subsystems of the vehicle, the working status of each component affects each other. In order to obtain the real real-time energy consumption of each subsystem and compon...
