Abstract
A creep control method for a vehicle is disclosed. The creep control method includes a limit-setting step and a limit release step. In the limit-setting step, a controller compares a speed of an input shaft of a transmission with a predetermined creep reference speed, and, if it is determined that the speed of the input shaft is lower than the creep reference speed, a creep minimum torque of a clutch for controlling creep driving of the vehicle is set to be a predetermined lower limit torque, which is larger than 0. In the limit release step, if the controller determines that the speed of the input shaft is increased above the creep reference speed while the creep minimum torque is limited to the lower limit torque, the creep minimum torque is set to 0.
Claims6
A creep control method for a vehicle, comprising:
- comparing a speed of an input shaft of a transmission with a predetermined creep reference speed through a controller, and, upon determining that the speed of the input shaft is lower than the creep reference speed, setting a creep minimum torque of a clutch for controlling creep driving of the vehicle to be a predetermined lower limit torque, the predetermined lower limit torque being larger than 0;
- and
- upon determining that the speed of the input shaft is increased above the creep reference speed while the creep minimum torque is limited to the predetermined lower limit torque, setting the creep minimum torque to 0.
A creep control method for a vehicle, comprising:
- upon determining that a vehicle speed is lower than a creep target vehicle speed through a controller, setting a creep minimum torque of a clutch for controlling creep driving of the vehicle to be a predetermined lower limit torque, the predetermined lower limit torque being larger than 0;
- and
- upon determining that the vehicle speed is increased above the creep target vehicle speed through the controller while the creep minimum torque is limited to the predetermined lower limit torque, setting the creep minimum torque to 0.
