Method for carrying out a test run on a test stand

Abstract

The aim of the invention is to allow measurement results from test runs to be superimposed and compared in a substantially more effective, faster, and improved manner. This is achieved in that a virtual route (A*-B*) is read from a data storage unit (4), wherein the virtual route (A*-B*) is stored as a sequence of geo-coordinates (P) and corresponding data (D) on the vehicle (1*), a driver, and / or an area surrounding the vehicle (1*), said data relating to the geo-coordinates (P), and used to carry out the test run for the virtual vehicle (1*). Measured data (M) of the virtual vehicle (1*) is detected and stored in relation to the geo-coordinates (P) during the test run.

Description

technical field [0001] The invention relates to a method for carrying out a test run of a virtual vehicle on a test bench. Background technique [0002] Experimental runs of test bench tests of vehicles or components of vehicles such as drive trains, internal combustion engines, transmissions, etc. are now partly determined from actual test drives. In this case, a real test road section is driven with a real vehicle and the measured data, as well as the surroundings of the road and the vehicle, such as traffic, etc., and specific events such as road signs, traffic lights, zebra crossings, etc., are detected. Through GPS and other measurement techniques, the road profile (downhill slope, uphill slope, curve, etc.), vehicle surface (geometry, material properties, etc.) and vehicle dynamic data (speed, acceleration, consumption, Internal combustion engine combustion indication data, exhaust emissions, etc.) and the surrounding environment (traffic, crosswind, temperature, pres...

AI Technical Summary

Problems solved by technology

Such test runs also cannot be directly compared

This causes considerable difficulties in practice when constructing comparable experimental runs and when comparing measured data
