Abstract

The invention discloses a hardware-in-the-loop simulation test bench for an automobile AFS. The hardware-in-the-loop simulation test bench comprises a host computer system with a built-in vehicle dynamics simulation subsystem and a built-in communication and sensor signal reproduction collection subsystem. The vehicle dynamics simulation subsystem is used for calculating vehicle travelling state data under all kinds of road conditions, and the communication and sensor signal reproduction collection subsystem is used for receiving the calculated data of the vehicle dynamics simulation subsystem, converting the data to a sensor signal, sending the sensor signal to the AFS, simultaneously collecting the feedback signal from the AFS and displaying and storing the data. The hardware-in-the-loop simulation test bench of the invention can be used in all kinds of tests for an automobile AFS, solves the problems of high danger coefficient, high cost, long period and poor repeatability in automobile installation and tests in the later stage of the development of an automobile AFS so that the hardware-in-the-loop simulation test bench lays an necessary basis for control strategy research and algorithm design verification of an AFS.

Description

technical field [0001] The invention relates to a simulation test platform for development and testing of auto parts, in particular to a simulation test platform for an automobile AFS (Adaptive Front-lighting System, Adaptive Front-lighting System). Background technique [0002] With the continuous development of society, people continue to put forward high requirements for the safety, environmental protection, energy saving and comfort of modern cars, and the car headlight system is an indispensable part of the whole system of the car, so the intelligent control of headlights is urgent need. The traditional headlights have a fixed irradiation angle and cannot provide illumination to the area inside the curve when turning, causing the driver to fail to detect obstacles on the curve in time, which affects driving safety; The inability to provide sufficient lighting brings inconvenience and traffic hazards to night driving, which greatly threatens the driver's night driving s...
