Abstract
Disclosed are a brake pedal assembly, a braking apparatus, and a control method, where the brake pedal assembly includes a pedal, a stroke sensor configured to detect a depression stroke of the pedal, Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal, and a controller configured to determine the depression stroke of the pedal using any one or any combination of the stroke sensor and the Hall sensors and to determine a required braking force of a vehicle, in response to the depression stroke of the pedal.
Claims11
A brake pedal assembly, comprising:
- a pedal;
- a stroke sensor configured to detect a depression stroke of the pedal;
- Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal;
- and
- a controller configured to determine the depression stroke of the pedal using any one or any combination of the stroke sensor and the Hall sensors and to determine a required braking force of a vehicle, in response to the depression stroke of the pedal.
A brake apparatus for a vehicle, comprising:
- a pedal;
- a stroke sensor configured to detect a depression stroke of the pedal;
- Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal;
- a controller configured to determine the depression stroke of the pedal using any one or any combination of the stroke sensor and the Hall sensors and to determine a required braking force of a vehicle, in response to the depression stroke of the pedal;
- a hydraulic circuit configured to transmit hydraulic pressure to wheels of the vehicle based on the required braking force;
- and
- solenoid valves configured and disposed to regulate flows of the hydraulic pressure in the hydraulic circuit.
A method of controlling a brake pedal assembly for calculating a required braking force of a vehicle using a stroke sensor configured to detect a depression stroke of a pedal and using of Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal, the method comprising:
- comparing a first depression stroke of the pedal calculated using the stroke sensor with a second depression stroke of the pedal calculated using the Hall sensors;
- determining whether a difference in a value of the first depression stroke and a value of the second depression stroke exceeds a threshold;
- determining that a failure has occurred in the stroke sensor, in response to the difference exceeding the threshold;
- and
- estimating the depression stroke of the pedal using a preset value, in response to the failure occurring in the stroke sensor.
