Problems solved by technology

[0006] (1) The existing technology uses an offline method to test the performance of the electric load, which is difficult to simulate the actual performance of the electric load after the vehicle is turned on;
[0007] (2) The existing technology cannot confirm the working voltage state of the electrical load in the vehicle environment, so the calculated electrical load performance error is relatively large

Abstract

The present invention discloses a vehicle electricity load performance test method. The method comprises the following steps of: S1, setting a test environment to a room temperature vehicle environment; S2, measuring a working current and a working voltage of an electricity load; S3, performing data validity determination of the working current and the working voltage; and S4, calculating equivalent resistance and power of the electricity load. The vehicle electricity load performance test method can improve the accuracy and the reliability of the vehicle electricity load detection and has animportant meaning for the vehicle energy flow analysis.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a method for testing the electrical load performance of a complete vehicle. Background technique [0002] The electric load of the whole vehicle refers to various types of electrical appliances of the car, including low beam lights, fog lights, wipers, etc. The energy flow of the whole vehicle refers to the energy consumption of each system during the driving process of the vehicle. It is of great significance to improve the fuel economy of the vehicle to study the proportion of the energy consumption of the engine, transmission, electrical load, chassis and other systems in the energy flow of the vehicle, and to effectively reduce the energy consumption of each system. Among them, electric energy is an important part of the energy flow consumption of the vehicle, and the study of electric energy can provide a basis for energy flow analysis. The electric energy consu...
