Abstract
Provided is an electric drum brake system, including: an electric drum brake configured to be driven by an electric motor; a current sensor configured to detect a current input to the electric motor; and a controller configured to, when parking is released, determine a parking release time based on a temperature of the electric drum brake, and when a maintenance time reaches the determined parking release time, end a parking release operation by stopping the electric motor, the maintenance time being a period of time while a state where a motor current detected by the current sensor reaches a target current is maintained.
Claims8
An electric drum brake system, comprising:
- an electric drum brake configured to be driven by an electric motor;
- a current sensor configured to detect a current input to the electric motor;
- and
- a controller configured to, when parking is released, determine a parking release time based on a temperature of the electric drum brake, and when a maintenance time reaches the determined parking release time, end a parking release operation by stopping the electric motor, the maintenance time being a period of time while a state where a motor current detected by the current sensor reaches a target current is maintained.
A control method of an electric drum brake system including an electric drum brake driven by an electric motor, the control method comprising:
- when parking is released, determining a parking release time based on a temperature of the electric drum brake, and
- when a maintenance time reaches the determined parking release time, ending a parking release operation by stopping the electric motor, the maintenance time being a period of time while a state where a motor current input to the electric motor reaches a target current is maintained.
