Abstract
The present disclosure relates to a zero-drag control device of an EMB system and a zero-drag control method using the same, which effectively control a drag phenomenon. By adjusting a gap between a disk and a pad in consideration of not only a braking intention through a brake pedal but also an accelerating intention through an accelerator pedal, the drag phenomenon can be effectively controlled and the braking response can be improved.
Claims18
A zero-drag control device of an EMB (electromechanical brake) system, the device comprising:
- a braking intention detecting unit that detects a driver's braking intention;
- an accelerating intention detecting unit that detects a driver's accelerating intention;
- a control unit that determines the braking intention and the accelerating intention transmitted respectively through the braking intention detecting unit and the accelerating intention detecting unit, and calculates a gap between a disk and a pad in consideration of both of the intentions;
- and
- a braking actuator for adjusting the gap between the disk and the pad under the control of the control unit,
- wherein the control unit includes:
- a pad gap calculator for calculating the gap between the disk and the pad in consideration of both the braking intention and the accelerating intention;
- and
- a plurality of pad gap controllers for receiving a calculation value from the pad gap calculator and each controlling an operation of the braking actuator provided for each wheel of a vehicle.

A zero-drag control method using a zero-drag control device, comprising:
- (a) a step of detecting the braking intention and the accelerating intention through a braking intention detecting unit and an accelerating intention detecting unit, respectively, and transmitting detection signals of the braking intention and the accelerating intention to a control unit;
- (b) a step of determining the braking intention and the accelerating intention and calculating a gap between a disk and a pad in consideration of both intentions in the control unit;
- and
- (c) a step of controlling the gap between the disk and the pad in real time based on the calculated gap in the control unit,
- wherein the control unit includes:
- a pad gap calculator for calculating the gap between the disk and the pad in consideration of both the braking intention and the accelerating intention;
- and
- a plurality of pad gap controllers for receiving a calculation value from the pad gap calculator and each controlling an operation of a braking actuator provided for each wheel of a vehicle.
