Abstract
The present disclosure provides a method for preventing interlock of a transmission. The method may include: sensing, with a controller, target currents of a plurality of solenoid valves, where each solenoid valve of the plurality of solenoid valves is connected to corresponding friction element; and when it is determined that target currents of at least two solenoid valves of the plurality of solenoid valves are equal to or greater than a predetermined current, interrupting, with the controller, a supply of power to the plurality of solenoid valves based on a degree of deviation of an actual speed of a transmission output shaft from a target speed for a predetermined time.
