Abstract
A brake system includes a stroke sensor to output a detection signal indicative of a status of a stroke of a brake pedal, and a first controller to receive the detection signal and to generate a switching signal in accordance with a displacement of the brake pedal based on a result of comparing the detection signal with a predetermined reference value. In particular, the switching signal is provided to at least one second controller configured to control an operation of another device in a vehicle based on an operation of the brake pedal.
Claims20
A brake system for a vehicle, comprising:
- a stroke sensor configured to output a detection signal indicative of a detected state of a stroke of a brake pedal;
- and
- a first controller configured to:
- receive the detection signal, and generate a switching signal in accordance with a displacement of the brake pedal based on a result of comparing the detection signal with a predetermined reference value,
- wherein the switching signal is provided to at least one second controller configured to control an operation of another device in the vehicle based on an operation of the brake pedal,
- wherein:
- the detection signal comprises:
- a first channel signal whose duty linearly decreases from a maximum duty to a minimum duty, and a second channel signal whose duty linearly increases from the minimum duty to the maximum duty according to an increase in the stroke of the brake pedal;
- and
- the first controller is configured to generate a first switching signal transitioning from a high state to a low state based on a result of comparing the first channel signal with the reference value, or a second switching signal transitioning from a low state to a high state based on a result of comparing the second channel signal with the reference value.
A brake system for a vehicle, comprising:
- a stroke sensor configured to detect a stroke of a brake pedal and output a first channel signal whose duty linearly decreases from a maximum duty to a minimum duty and a second channel signal whose duty linearly increases from the minimum duty to the maximum duty based on a displacement of the stroke of the brake pedal;
- a first controller configured to generate a first switching signal transitioning from a high state to a low state and a second switching signal transitioning from a low state to a high state according to a result of comparing at least one of the first channel signal or the second channel signal with a predetermined reference value;
- and
- at least one second controller configured to control an operation of another device in the vehicle based on an operation of the brake pedal upon receiving at least one of the first switching signal or the second switching signal.
