Brake Systems For Automobiles
The brake assist systems refer to the braking technology which increases the braking pressure in case of an emergency situation
. The brake assist recognizes the circumstances in which emergency braking is required by the process of measuring the speed with which the pedal of the brake is being pushed, some even measure the rapidity with which the gas pedal has been released and the pre tensioning of the brakes when there is a panic release. When this is detected then the brake assist system takes over and created maximum brake boosts which can immediate bring the car to a halt. This technology was first developed in 1992 when it was discovered in a research that 90% of the people do not apply enough force to put a break in case of emergency situations. This system has been found to decrease the stopping distance by almost 20% in many cases and leading to averting some major accidents.
The regenerative brake makes use of the energy recovery mechanism which reduces the speed of the vehicle by the conversion of kinetic energy into a different form which is either immediately used or it can be stored till the time it needs to be used. Commonly, the regenerative brakes made use of an electric motor as the generator of electricity; in this the energy is stored in the batteries or in the capacitors to be used later on. This energy can also be stored mechanically through hydraulics or pneumatics of a flywheel which is in rotation. The vehicles which are driven by the electric motor make use of their motor as a generator when it makes use of regenerative braking; this is operated with the help of a generator while using the brakes.
Regenerative brakes are mostly used on the automobiles driven in hybrid gas or electricity so that this energy can be used for stopping the vehicles. The main negative aspects of a regenerative brake are that the generated current with the supply characteristics and the maintenance cost of these is high. Unlike the regenerative brakes, the dynamic brakes dissipate the electrical energy in the form of heat by passing the current via the large banks of the variable resistors. The main feature of the electronic braking is that it gives an instant brake response on the application of the brake and leads to the release of the direct proportion with the pedal pressure.
