Abstract
An apparatus of estimating wear of brake pads may include an electric brake configured to adjust a position of a piston using a motor, wherein the piston is configured to generate a friction force by pressing the brake pads onto a disc rotating with a wheel, and a controller electrically connected to the motor and configured to control the motor and estimate a degree of wear of the brake pads based on a required time consumed for the motor to move the piston so that the brake pads press the disc.
Claims20
An apparatus of estimating wear of brake pads, the apparatus comprising:
- an electric brake configured to adjust a position of a piston using a motor, wherein the piston is configured to generate a friction force by pressing the brake pads onto a disc rotating with a wheel;
- and
- a controller electrically connected to the motor and configured to control the motor and estimate a degree of wear of the brake pads based on a required time consumed for the motor to move the piston so that the brake pads press the disc.
An apparatus of estimating wear of brake pads, the apparatus comprising:
- an electric brake configured to adjust a position of a piston using a motor, wherein the piston is configured to generate a friction force by pressing the brake pads onto a disc rotating with a wheel;
- and
- a controller electrically connected to the motor and configured to control the motor and estimate a degree of wear of the brake pads based on a moving distance at which the motor moves the piston until the brake pads press the disc.
A method for estimating wear of brake pads in an electronic brake configured to adjust a position of a piston using a motor and generate a braking force by allowing the piston to move the brake pads and be in contact with a disc, the method comprising:
- checking, by a controller, a required time;
- and
- estimating, by the controller, degree of wear of the brake pads based on the required time,
- wherein the required time is a time period consumed for the motor to move the piston so that the brake pads press the disc.
