An Approach to Load Sensing Brake Proportioning for Passenger Cars and Light Trucks

Load sensing brake proportioning is a means of optimizing the ratio of front-to-rear wheel retarding forces for the full range of vehicle loadings and decelerations. A relatively simple system of providing two-axled vehicles with improved brake balance has been developed. Simulation studies of vehicle brake system requirements, effects of a pressure regulating device used to implement these requirements, and the resulting improvements are compared in actual tests of vehicle and hardware.
