Abstract

The invention relates to the technical field of intelligent piloting and particularly relates to an intelligent piloting advanced aided driving hardware-in-the-loop test system and method. The system comprises a power management module, a work station, a real-time simulation machine, video injection equipment, fault injection equipment, signal conditioning equipment, vehicle equipment, a programmable power supply and an intelligent piloting domain controller. A real intelligent pilot domain controller is adopted, required sensor signals are constructed through scene software and are injected into the domain controller, software algorithm and hardware defects can be found more timely and more comprehensively through the testing method, the development period is shortened, and a large amount of risk cost brought by real vehicle testing can be saved; by analyzing real vehicle data, generating an OpenDrive format and importing scene simulation software, a problem of matching of a simulation map and an actual algorithm loading map module is solved; and a vehicle machine outputs and feeds back navigation information to the controller by receiving the positioning information simulated by the virtual scene so that verification of a high-precision positioning fusion algorithm is realized.

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. ...
