The invention discloses a safety guarantee system and method for an electric vehicle test, and the system comprises a switching action interaction module which is used for receiving a switching action, and a switching action transmission module which is used for transmitting the switching action to a signal switching module. And the signal switching module is used for disconnecting the acceleration signal connection between the first end and the second end under the action of the switching action, otherwise, maintaining the acceleration signal connection. According to the safety guarantee system for the electric vehicle test, safety redundancy of an existing system of an electric vehicle is formed, and the safety guarantee system for the electric vehicle test can be constructed based on a mechanical structure and a circuit structure, so that dependence on a complex software algorithm is reduced; on one hand, the possibility of faults caused by software algorithm running errors can be reduced, and on the other hand, fault spreading caused by software algorithm running errors can be blocked. The invention is widely applied to the technical field of automobiles.
