Abstract
A method for preventing overheating of a clutch for a vehicle may include determining, by a controller, whether a state of the vehicle satisfies a hill hold condition; acquiring, by the controller, a temperature of a clutch between an engine and a transmission when the hill hold condition is satisfied; applying, by the controller, a first torque having a predetermined square wave shape to the clutch when the temperature of the clutch reaches a first temperature; and applying, by the controller, a second torque having a predetermined sine wave shape to the clutch when the temperature of the clutch reaches a second temperature higher than the first temperature.
