Abstract: A parking brake (PB) system is a type of mechanical brake-by-wire system that is the conventional lever parking system by generating a clamping force for parking using lever system. At the push of a button, a driver can easily apply or release the parking brake; this enables elderly or disabled persons to easily apply a full braking load. The PB system operates quickly and over a wide force range through the use of electrical components It is sometimes also used to prevent a vehicle from rolling when the operator needs both feet to operate the clutch and throttle pedals. Automobile hand brakes usually consist of a cable directly connected to the brake mechanism on one end and to a lever or foot pedal at the driver position. The mechanism is often a hand-operated lever (hence the hand brake), on the floor on either side of the driver or a pull handle located below and near the steering wheel column, or a (foot-operated) pedal located far apart from the other pedals. Although sometimes known as an emergency brake, using it in any emergency where the footbrake is still operational is likely to badly upset the brake balance of the car and vastly increase the likelihood of loss of control of the vehicle, for example by initiating a rear-wheel skid. Additionally, the stopping force provided by using the handbrake is small and would not significantly aid in stopping the vehicle.
