Hardware-in-loop test system of intelligent driving controller

Abstract

The embodiment of the invention provides a hardware-in-loop test system of an intelligent driving controller. The system comprises a scene simulation subsystem, an interface simulation subsystem and afault injection subsystem. The interface model subsystem comprises a vehicle model, a real-time simulator, a PWM board card, a CAN board card and a visual simulation device. The scene simulation subsystem is used for setting up and designing a corresponding virtual scene according to a real traffic scene and setting up various corresponding virtual sensor models according to real electrical appliance characteristics of a sensor actually adopted by a vehicle. Sensor fault injection is realized through the fault injection subsystem so as to simulate the fault of the sensor. The PWM board card,the CAN board card and the visual simulation device are used for converting various virtual sensor signals into real sensor electrical signals which can be recognized by the intelligent driving controller. And thus, multiple function tests are performed on the intelligent driving controller.

Description

technical field [0001] The invention relates to the technical field of intelligent driving, and more specifically, relates to a hardware-in-the-loop testing system of an intelligent driving controller. Background technique [0002] Intelligent driving system is a kind of highly complex multi-component system, including components such as intelligent driving controller and sensors. The intelligent driving controller comprehensively utilizes the perception input obtained by multiple sensors for fusion, planning and decision-making, and independently controls the vehicle for driving. The working environment of the intelligent driving controller is complex and changeable, and safe driving is required to ensure the safety of passengers and pedestrians on the road. Therefore, the design and verification of the intelligent driving controller must follow a strict process. [0003] At present, the hardware-in-the-loop test of the intelligent driving controller only meets the general...
