Brake Pedal Position Sensors

Introduction

When depressing the brake pedal, the auto’s hydraulics engage and slow or stop the vehicle.  In addition, two other functions can also occur, one of which is critical to the operation of the vehicle- disengaging of the cruise control.  The other function is to switch on the brake lights to alert other vehicles that the car is slowing down and/or is going to stop.  In the past, these latter two items typically used electromechanical sensors to sense the brake pedal motion but failed to disengage the cruise control, allowing the engine to continue its race forward increasing the possibility of a potentially dangerous collision.  Standex Electronics’s automotive sensor designers have successfully solved the reliability problem by using reed sensor technology…
