Fabrication of Automatic Handbrake System

One of the most important safety features in an automobile is brake. A typical automobile consists of two types of brakes, one for retarding the speed of vehicle while it is in motion and other is to hold the vehicle in its place when standing still or parked. The latter is mostly important when the vehicle is parked on slope. It is important to disengage the handbrake before starting the vehicle from rest position. Sometimes due to negligence or in emergency conditions, we humans often forget to apply parking brakes. This may lead to rolling of vehicle in case of slopes and collision with other vehicles in parking area. Sometimes if service brake fails parking brakes are used as a emergency brake to stop the vehicle. This Project provides a new concept design of the parking brake system that has simple and low-cost characteristics. This system uses electrically operated components using solenoid circuits. This system operates depending on the positions of the key. When the ignition switch is turned on the handbrake disengages and engages when the ignition is turned off.
