Fusion calibration test method and device, vehicle-mounted system and vehicle

The invention relates to a fusion calibration test method and device, a vehicle-mounted system and a vehicle. The fusion calibration test method comprises the steps of defining a test case, an associated calibration quantity, a calibration quantity constraint condition, a test result signal and a test evaluation index; performing an automated test according to the test case; obtaining a to-be-tested associated standard quantity according to the standard quantity constraint condition, and taking the to-be-tested associated standard quantity as test input of the test case to execute the test case; and obtaining a test result signal of the to-be-tested associated calibration quantity, and screening the associated calibration quantity corresponding to the test result signal conforming to the test evaluation index. According to the embodiment of the invention, the problem that the development period for completing the test work and the calibration work is relatively long in the existing scheme can be solved, the d
