Description

technical field [0001] The invention relates to a simulation test bench, in particular to a driver-in-the-circle vehicle active collision avoidance simulation test bench. Background technique [0002] With the advancement of sensor technologies such as machine vision and radar, automotive safety assistance technologies such as active collision avoidance have also developed rapidly. [0003] Patent CN101739857A proposes a human-computer interaction simulation system that simulates the response of the car to the driver's operation under various working conditions. The platform installs sensors on the brake device, clutch, gear, accelerator and steering wheel of the car respectively, collects the signals of each sensor through the data acquisition card, converts them into digital signals and sends them to the computer for processing, and sends the vehicle through the audition output system. The status is fed back to the driver to form a closed loop. The system is easy to coll...

Problems solved by technology

However, the system fails to realize software co-simulation and hardware-in-the-loop, and cannot verify and optimize the control algorithm in real time.

[0005] Based on the above-mentioned research deficiencies, the real-vehicle test to verify the active collision avoidance control function of the vehicle is dangerous and expensive, which brings difficulties to the real-vehicle test; and the ordinary hardware-in-the-loop test system, because there is no real-time participation of the driver and feedback, cannot fully reproduce the interaction characteristics of the actual human-vehicle-road system
