Abstract: The present disclosure discloses a terrain based dynamic gear shift control method and system for a vehicle. The method includes: during running of a vehicle, obtaining a current terrain; according to the current terrain, the economic gear shift strategy, and the dynamic gear shift strategy, generating a current gear shift strategy curve; and according to the current gear shift strategy curve, controlling a transmission to perform gear shift. The present disclosure can make the vehicle have wider adaptability, and achieve a better dynamic balance between economy and dynamic performance.

Abstract: A vulnerability detection method includes obtaining a target test program including system calls and first input parameters corresponding to the system calls required for normal running of a device driver, where the system calls are arranged based on a calling relationship for the normal running of the device driver, obtaining a sequence to be inserted, wherein the sequence to be inserted comprises at least one system call, mutating the target test program based on the sequence to be inserted and second input parameters corresponding to the sequence to be inserted, and detecting a vulnerability of the device driver based on running information about the device driver obtained during execution of the mutated target test program.

Abstract: A method includes receiving a test input, obtaining a resource access feedback indicating an access for a resource based on the test input, selectively, based on the resource access feedback indicating whether a first-time accessed resource is accessed based on the test input, adding the test input to a test input queue, and performing a fuzz test based on the test input queue with the test input.

Abstract: The present disclosure relates to an apparatus and method for fuzz testing. The method includes receiving a test input, obtaining a resource access feedback indicating an access for a resource based on the test input, and determining whether to add the test input to a test input queue based on the resource access feedback.
