Abstract
A USB interface automatic test method for vehicle-carried device was introduced, which was used to evaluate USB stability through monitoring the CPU load ratio, memory occupancy and transfer rate in the vehicle-carried device USB data transmission. The test method was used to test the function and performance of vehicle-carried device USB interface effectively, and ensured the USB communication reliability, which improved the operating efficiency greatly.
