Abstract
Official abstract text for this publication.
A method for releasing creep torque control of a vehicle before a stop includes a step of when creep torque is controlled for a shift before a stop of the vehicle, creep torque control is released in consideration of a current shift gear position if an actual creep torque value controlled during a shift becomes equal to a target creep torque value.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for releasing creep torque control of a vehicle before a stop, comprising: when creep torque is controlled for a shift before a stop of the vehicle, creep torque control is released in consideration of a current shift gear position if an actual creep torque value controlled during a shift becomes equal to a target creep torque value. 2 . The method of claim 1 , wherein if a difference between the actual creep torque value controlled during a shift and the target creep torque value is a predetermined reference value or less, it is judged that the actual creep torque value and the target creep torque are equal. 3 . The method of claim 1 , wherein when the current shift gear position is a first gear position, creep torque control is released. 4 . The method of claim 1 , wherein when the current shift gear position is a parking position, creep torque control is released. 5 . The method of claim 1 , wherein when the current shift gear position is a parking position, even if there is a difference between the actual creep torque value controlled during a shift and the target creep torque value, creep torque control is released. 6 . The method of claim 1 , wherein when the current shift gear position is a reverse position, creep torque control is released. 7 . The method of claim 1 , wherein when the current shift gear position is a reverse position, even if there is a difference between the actual creep torque value controlled during a shift and the target creep torque value, creep torque control is released. 8 . The method of claim 1 , wherein when the current shift gear position is a neutral position, creep torque control is released. 9 . The method of claim 1 , wherein when the current shift gear position is a neutral position, even if there is a difference between the actual creep torque value controlled during a shift and the target creep torque value, creep torque control is released. 10 . The method of claim 1 , wherein when the current shift gear position is a second gear position or a third gear position and a current vehicle speed is a predetermined threshold value or less, creep torque control is released. 11 . The method of claim 1 wherein the current shift gear position is a shift gear position of a dual clutch transmission (DCT).
