Embodiment 1
[0028] The assisted driving vehicle hardware-in-the-loop simulation testing method of the present invention comprises the following steps:
[0029] The corresponding scene information is collected according to the set test scene. The test scene includes environmental elements and traffic elements around the vehicle. The environmental elements include weather conditions, lighting conditions, and traffic signs. The traffic elements include the motion posture and trajectory of moving objects around the vehicle. Then, the corresponding scene information is sent to the smart car controller to be tested, and the smart car controller to be tested performs information fusion and decision-making according to the scene information, and sends the instruction of lateral dynamics to the driver model in the hardware-in-the-loop simulation platform. The longitudinal dynamics commands are sent to the vehicle controller, and the vehicle controller sends the longitudinal dynamics commands to the...
