Abstract
Provided are an integrated device of an EPB lever and a parking button, and an EPB control system and method using the same, in which a tiltable EPB lever and a pressable parking button are integrally provided in a single location, allowing a vehicle braking force to be easily exerted by drive control of an EPB motor for an EPB operation based on an operation of the integrated EPB lever and parking button, and by drive control of the EPB motor for the EPB operation in response to a failure of the EPB lever or the parking button.
Claims20
An integrated device of an electrical parking brake (EPB) lever and a parking button, the integrated device comprising:
- a first housing guiding a vertical movement of the parking button, the parking button pressably disposed on the first housing;
- a first magnetic body disposed on at least one side of first and second sides of the parking button;
- a second housing spaced apart around a peripheral portion of the first housing and configured to pivot the EPB lever, the EPB lever operatively disposed on the second housing and disposed around an upper peripheral portion of the parking button;
- a second magnetic body disposed on at least one side of first and second sides of the EPB lever;
- and
- a printed circuit board (PCB) disposed on a lower portion of the first housing and configured to detect an operation of the parking button by a downward movement of the first magnetic body and detect an operation of the EPB lever by a pivotal movement of the second magnetic body.
An electrical parking brake (EPB) control system comprising:
- a parking button pressably disposed on a first housing and including a first magnetic body mounted on at least one side of first and second sides thereof;
- an EPB lever operatively disposed on a second housing spaced apart around a peripheral portion of the first housing, disposed around an upper peripheral portion of the parking button, and including a second magnetic body disposed on at least one side of first and second sides thereof;
- a printed circuit board (PCB) disposed on a lower portion of the first housing and configured to detect an operation of the parking button by a downward movement of the first magnetic body and to detect an operation of the EPB lever by a pivotal movement of the second magnetic body;
- a second controller configured to receive an operation signal of the parking button and an operation signal of the EPB lever from the PCB and to perform control to drive an EPB motor for an EPB braking operation;
- and
- a first controller configured to receive an operation signal of the parking button and an operation signal of the EPB lever from the PCB, and to perform control to drive the EPB motor for the EPB braking operation, in preparation for a failure of the second controller.
An electrical parking brake (EPB) control method comprising:
- pressing a parking button including a first magnetic body, or tilting an EPB lever including a second magnetic body in an operation direction or operation release direction;
- detecting, by a printed circuit board (PCB), an operation of the parking button by a downward movement of the first magnetic body;
- detecting, by the PCB, an operation of the EPB lever by a pivotal movement of the second magnetic body;
- receiving, by a second controller, an operation signal of the parking button and an operation signal of the EPB lever from the PCB, and performing control to drive an EPB motor for an EPB braking operation;
- and
- receiving, by a first controller, an operation signal of the parking button and an operation signal of the EPB lever from the PCB, and performing control to drive the EPB motor for the EPB braking operation, in preparation for a failure of the second controller.
