Hand brake is one of the most important component in vehicles. Conventional handbrake system works using a ratchet locking mechanism that will keep it engaged until a release button is pressed. Driver error can lead to accidents in which handbrake is not engaged. To overcome this, an Automatic Hand Brake engaging and disengaging system is proposed. The hand brake engagement and disengagement is done using a combination of rack & pinion arrangement and microcontroller. The microcontroller process signals from ignition switch which checks whether the ignition is ON or OFF, and in-turn checks the gear lever to see whether the gear is in neutral position and also checks the signal from proximity sensor to sense if the wheel is in motion. If all the conditions are satisfied, a signal is given to the motor. As the motor rotates the pinion, it causes the rack to move linearly causing the engagement of handbrake. On turning the ignition on and engaging the gear lever a spring attached to handbrake automatically disengages the handbrake.
