Abstract
A method of controlling creep torque of a vehicle being provided with an Auto Hold function, includes: a brake detection step for detecting a brake signal of the vehicle; a braking step for activating a brake force and reducing creep torque according to the brake signal; a start detection step for detecting a start signal of the vehicle after the vehicle is stopped; and a starting step for deactivating the brake force and increasing the creep torque according to the start signal.
Claims6
A method of controlling creep torque of a vehicle, the vehicle being provided with an Auto Hold function, comprising:
- detecting a brake signal of the vehicle;
- activating a brake force and reducing creep torque according to the brake signal;
- detecting a start signal of the vehicle after the vehicle is stopped;
- and
- deactivating the brake force and increasing the creep torque according to the start signal,
- wherein the Auto Hold function is activated to maintain the brake force and to reduce the creep torque when the vehicle is stopped after the brake signal is detected,
- wherein the brake force remains activated to reduce the creep torque when a signal of a change in position of a gear shift lever is detected during activation of the Auto Hold function, and
- wherein, when the start signal is detected, the brake force is deactivated and the creep torque is increased at the same time, such that the brake force gradually decreases to zero and the creep torque gradually increases to a predetermined target value.
A method of controlling creep torque of a vehicle, the vehicle being provided with an Auto Hold function, comprising:
- detecting a brake signal;
- activating a brake force, thereby causing a reduction of the creep torque, according to the brake signal;
- detecting a start signal while the brake force is activated;
- and
- deactivating the brake force, thereby causing an increase of the creep torque, according to the start signal;
- activating the Auto Hold function to maintain the brake force and reduce the creep torque when the vehicle is stopped after the brake signal is detected;
- and
- maintaining the brake force to reduce the creep torque when a signal of a change in position of a gear shift lever is detected during activation of the Auto Hold function,
- wherein, when the start signal is detected, the brake force is deactivated and the creep torque is increased at the same time, such that the brake force gradually decreases to zero and the creep torque gradually increases to a predetermined target value.
