Abstract

The invention relates to an automatic drive simulator based driving behavior hardware-in-loop simulation testing system, which comprises a simulation module, a sensor module, a domain controller DCU,a camera obscura and a driving simulator. The camera obscura comprises a second display and a camera, and the driving simulator comprises a first display, a driving input device and a computer. The driving input device is used for a driver to input driving control signals, and a driving simulation program is installed in the computer. The first display and the driving input device are both connected with the computer, the simulation module generates a simulation model on the basis of data acquired by the sensor module to receive the driving control signals, inputted by the driver, sent by thedriving input device, the simulation model is updated, synchronous displaying is realized through the second display and the first display, the camera acquires contents displayed by the second displayand sends to a domain controller DCU, and learning is realized through the controller. Compared with the prior art, the system has the advantage of improvement of automobile drive stability and the like.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a driving behavior hardware-in-the-loop simulation test system based on an automatic driving simulator. Background technique [0002] Autonomous driving tests are divided into simulation tests, closed road tests, and open road tests. Simulation tests are widely used in the development of autonomous driving functions due to their advantages such as good repeatability, high safety, and high test efficiency. Hardware-in-the-loop testing is an important part of simulation testing. Existing hardware-in-the-loop simulation testing usually imports autonomous driving algorithms into domain controllers, and then connects hardware such as cameras and radars to simulation testing platforms for simulation testing. [0003] The traditional hardware-in-the-loop simulation test platform consists of HIL hardware, HIL software, real-time simulation model, camera obscura, domain controller DCU, ra...
