Description

Apparatus and Method for Shutting Off Power for Vehicle The present invention relates to a vehicle power cutoff device and method, and more specifically, to a vehicle power cutoff device and method capable of cutting off the current supplied to a motor when a vehicle accelerates suddenly. Sudden acceleration refers to a phenomenon in which a vehicle moves contrary to the driver's intention due to the generation of abnormal engine torque, even when the driver has not pressed the accelerator pedal or has only pressed it lightly. When a sudden acceleration accident occurs, it can cause material and human damage not only to the driver and passengers but also to the surrounding area; therefore, technology capable of safely stopping the vehicle in such situations is required. The background technology of the present invention is disclosed in Korean Published Patent Application No. 10-2024-0029905 (March 7, 2024).
