A testing method for a blind spot detection system for an automobile includes: applying an electromagnetic interference signal to the tested automobile through an electromagnetic interference signal application device, meanwhile, simulating a static obstacle or a moving obstacle within a detection range through a testing device, and if the blind spot detection system for the tested automobile is activated, determining that the testing is passed. Repeatable and reproducible testing for the electromagnetic safety of the blind spot detection system may be realized.

Testing method for blind spot detection system for automobile, device, and medium

The present application relates to the field of enzyme engineering, especially relates to a pullulanase as well as preparation and use thereof. The pullulanase and coding gene thereof were obtained by random mutation by using the Error-prone PCR technique on the gene of wild-type pullulanase to obtain a mutant PLUM. The enzyme activity of the mutant PLUM was improved by 57.03% compared with the wild-type pullulanase PLUM.
