Claim 14:
15. A slope travel control method for controlling a driving torque of a vehicle without braking torque so that the vehicle stops or travels on a slope in a virtual accelerator position sensor (APS) mode in which the driving torque is controlled by a third controller performing a slope travel control for determining a hill hold torque regardless of a degree of adjustment of an accelerator pedal in the vehicle by a user, the slope travel control method comprising:
increasing the driving torque from a first hill hold torque of the hill hold torque to a first target torque at a first inclination;
resetting the first hill hold torque, the first inclination, and the first target torque to a second hill hold torque of the hill hold torque, a second inclination and a second target torque, respectively, when a wheel slip including a preset value or more than the preset value occurs in the vehicle;
increasing the driving torque from the second hill hold torque to the second target torque at the second inclination; and
repeatedly performing the increasing the driving torque,
wherein the hill hold torque is a torque for stopping the vehicle on the slope by allowing a driving unit operatively connected to the third controller to generate the driving torque without operating a brake of the vehicle on the slope, and
wherein the first inclination and the second inclination are different.
