Increasing brake performance during extreme conditions

摘要

Problems persist in brake systems performance when used in extreme conditions (under high speeds, traffic, etc.) and in heavy vehicles. The object of this work is to investigate the possibilities for further improving typical braking system used in extreme driving conditions. The engineering approach and technical scheme has been developed for application based on standard commercially available brake components. The mechanical part of the braking system is combined with an electrical circuit for control and regulation. This consists of an electromagnet, which is built into the braking system between the brake pedal and the vacuum amplifier. This magnet can provide additional power to the brake regulator up towards 100 kg. Under normal conditions this braking system (electromagnetic device) would not operate and would only be initiated under extreme conditions, when the acceleration and the movement of the main cylinder's piston rod becomes larger then the standard value. An appropriate algorithm and numerical calculation is suggested in order to design, develop and test this engineering approach. The system discussed makes control and regulation less dependent on driving conditions and increases the efficiency of brake performance thereby decreasing the risk of road accidents.
