Abstract
In a pneumatic brake system for a motor vehicle, a variable speed electric motor is connected to a high voltage direct current power supply for variable energization, thus varying the operating rate of a compressor and the rate of pressurization of the brake system storage tanks. The operating rate of the compressor is varied responsive to pressure readings taken from the storage tanks during pressurization to minimize energy consumption.
