DRIVE CONTROL METHOD OF VEHICLE BY DETECTED DIELECTRIC BREAKDOWN

摘要

PURPOSE: A drive control method for a vehicle by a detected dielectric breakdown is provided to detect an error occurrence in a high-voltage component by checking each switch of a junction box when a dielectric breakdown is caused, and control the vehicle so that the vehicle can drive on normally, be limited or impossible to drive according to the component which an error occurred in. CONSTITUTION: A drive control method for a vehicle by a detected dielectric breakdown comprises a step of: measuring insulation resistance between a frame ground of the vehicle and a high-voltage battery(S100); determining error occurrence by comparing the measure insulation resistance to a tolerance(S200); if the measure insulation resistance is below the tolerance, checking whether each high-voltage component has an error by measuring insulation resistance after sequentially turning off each switch of a junction box for supplying power to high-voltage components(S300); and controlling drive of the vehicle based on the determination whether driving of the vehicle is affected by the high-voltage part having an error(S400).
