Development of an Emergency Parking System for Automobiles 2003-01-3307
The object of this work was to design an innovative and an improved emergency parking brake system for the automobile.
The engineering approach and technical design have been developed based on standard commercially available brake components.
This system operates on the basis of pneumatic chambers connected to individual wheel brakes. Under normal driving conditions air pump maintains a certain level of pressure in a special receiver. A system comprised of two automatically operating valves provides high-pressure air delivery to the pneumatic chambers, which switch the parking brake system on or off. In the case of air pump failure there is enough pressure in the receiver for few cycles of on and off braking. In the case of main braking system failure high-pressure emergency brake system could be used for regular braking.
The general system design and specific details of each component is described in details. An appropriate algorithm and numerical calculation is suggested in order to design, develop and test this engineering approach.
The system discussed should make automobile control and regulation more convenient and less dependent on driving and parking conditions (including driver physiological status) and increases the efficiency and reliability of brake performance thereby decreasing the risk of automobile accidents. This more convenient parking brake system could replace existing mechanical version.
