A whole vehicle electric balance simulation test method

Abstract

The invention discloses a whole vehicle electric balance simulation test method. An electric balance simulation model is established through software; And simulating each working condition according to the electric balance experiment standard of each main engine plant, displaying parameters corresponding to the electric balance judgment standard, and comparing the display parameters with the electric balance standard to obtain a simulation test result. The method has the advantages that the cost of manpower and material resources is low, the period is short, and the verification frequency andresource consumption of a special vehicle person are reduced; Model selection configuration adjustment is flexible, problems are easy to find in time, and adjustment is convenient; Virtual developmentis achieved, adaptability is high, and precision is high.

Description

technical field [0001] The invention relates to the field of automotive electrical design, in particular to a simulation test method for electrical balance of a complete vehicle. Background technique [0002] With the development of technologies such as vehicle safety, entertainment, and customer comfort requirements, automotive electronic and electrical configuration modules are becoming more and more abundant, and the power supply requirements of the vehicle are becoming more and more diverse, including stepless fans, automatic adjustment air conditioners, LEDs and lasers. Lights, integrated dual screens, sensor wipers, i-boost, power amplifiers, driving recorders and other after-installation configurations, these high-power loads have a greater impact on the electrical balance of the vehicle; in addition, different OEMs target different platforms Models equipped with different moving parts and generators, different engine idling speed strategies, and generator speed ratio...

AI Technical Summary

Problems solved by technology

[0003] At present, most OEMs adopt experience evaluation or bench verification method, the accuracy of experience evaluation is low, and the failure rate of actual vehicle verification in the later stage is high. The bench test cycle is long, manpower, material and financial resources are consumed, and it is difficult to be efficient and accurate in the project development stage. Determine the match between the vehicle power supply system and the load demand
