Problems solved by technology

[0008] However, in the EPB system, if the motor continues to be operated regardless of the motor being overloaded or generating high temperature heat, phenomena such as motor burnout may occur, resulting in failure of the brake system

Embodiment Construction

[0023] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the drawings, wherein like reference numerals refer to like elements throughout.

[0024] figure 1 is a view explaining the configuration of the electronic parking brake system according to the embodiment of the present invention, and figure 2 is interpretation figure 1 View of the control system of the electronic parking brake system shown in . like figure 1 and figure 2 As shown, the wheel speed sensors 4 are respectively arranged on the front wheel disc 6 and the rear wheel disc 18 of the vehicle. Furthermore, a front wheel actuator 8 or a rear wheel actuator 20 serving as a service brake is arranged on the front wheel disc 6 or the rear wheel disc 18 , respectively. These travel actuators are connected to a driver-operable brake pedal 52 .

[0025] The rear disc 18 is equipped with a parking brake 22 for generating a braking force to keep th...

Abstract

Disclosed are an electronic parking brake system and a control method thereof. An aspect is to protect an electronic parking brake system by judging whether it enters a control mode based on results of monitoring a peripheral temperature of the electronic parking brake system and a motor temperature after operation. The electronic parking brake system includes a locking / unlocking switch to lock or unlock an electronic parking brake, a motor to drive the electronic parking brake, a temperature sensor to measure a peripheral temperature around the motor, and a controller that limits a locking function of the electronic parking brake when the repetition number of locking / unlocking operations of the electronic parking brake is zero for a predetermined short time under assumption that the temperature sensor breaks down, so as to prevent occurrence of breakdown due to overload and overheating of the motor.

Description

technical field [0001] Embodiments of the invention relate to an electronic parking brake system for a vehicle. Background technique [0002] The vehicle is equipped with a braking system for slowing down or stopping. Such braking systems may include service brakes to slow or stop the vehicle while driving and a parking brake to be used when stopping the vehicle or parking it. [0003] The parking brake consists of a driver-operable brake pedal and brake pads that brake discs (drums) on the front and rear wheels in response to the operation of the brake pedal. The parking brake is used to prevent movement of a stationary vehicle. When the driver pulls the lever of the parking brake, the pads towards the rear wheels come into close contact with the drum through the cables connected to the lever, maintaining wheel braking. For example, when parking a vehicle on an incline, the driver typically operates the parking brake to prevent the vehicle from rolling forward or backwar...
