Abstract

The present invention relates to the technical field of intelligent piloting, in particular to a hardware-in-the-loop testing system and method for intelligent piloting advanced assisted driving, including a power management module, a workstation, a real-time simulator, a video injection device, a fault injection device, a signal conditioning device, and a car machine Equipment, program-controlled power supply, and intelligent domain controller; the present invention uses a real intelligent domain controller, and injects these signals into the domain controller through scene software to construct the required sensor signals. This test method can discover software algorithms in a more timely and comprehensive manner. and hardware defects, shorten the development cycle, and save a lot of risk costs caused by real vehicle testing; by analyzing the real vehicle data, generating the OpenDrive format, and importing the scene simulation software, the problem of matching the simulation map with the actual algorithm loaded map module is solved; The machine receives the positioning information simulated by the virtual scene, and feeds back the navigation information output to the controller to realize the verification of the high-precision positioning fusion algorithm.

Description

technical field [0001] The invention relates to the technical field of intelligent piloting, in particular to a hardware-in-the-loop testing system and method for intelligent piloting advanced assisted driving. Background technique [0002] The Intelligent Navigator Advanced Assisted Driving System is based on the functions of cruise speed control, vehicle distance maintenance, steering assistance and turn signal control lane change, etc., and supports the vehicle to navigate within the coverage area of ​​the high-precision map according to the navigation path planning. Most highways and urban elevated roads realize automatic entry and exit ramps and switch main roads. At the same time, it can automatically adjust vehicle speed, intelligently change lanes and overtake slow vehicles according to information such as road speed limit and environmental perception, so as to realize automatic navigation according to the navigation route under the specified path. assisted driving. ...
