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.
Claims11
A method of controlling creep torque of a vehicle, the vehicle being provided with an Auto Hold function, comprising:
- 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.
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.
A system for controlling creep torque of a vehicle, the vehicle being provided with an Auto Hold function, comprising:
- a brake detection unit that detects a brake signal of the vehicle;
- a start detection unit that detects a start signal of the vehicle;
- a braking unit that activates a brake force of the vehicle;
- an activation unit that activates creep torque of the vehicle;
- and
- a control unit that:
- i) detects the brake signal from the brake detection unit, ii) activates the brake force through the braking unit, iii) controls the activation unit to reduce the creep torque while the brake force is activated, iv) detects the start signal of the vehicle from the start detection unit while the brake force is activated, and v) deactivates the brake force of the braking unit, thereby increasing the creep torque through the activation unit.
A non-transitory computer readable medium containing program instructions for controlling creep torque of a vehicle, the vehicle being provided with an Auto Hold function, the computer readable medium comprising:
- program instructions that detect a brake signal;
- program instructions that activate a brake force, thereby causing a reduction of the creep torque, according to the brake signal;
- program instructions that detect a start signal while the brake force is activated;
- and
- program instructions that deactivate the brake force, thereby causing an increase of the creep torque, according to the start signal.
