DEVELOPMENT OF A LOW COST ANTI-LOCK BRAKE SYSTEM FOR SMALL MOTORCYCLES
The study was a continuation of earlier work reported in Towards a Low Cost, Highly Reliable Anti-Lock Brake System for Small Motorcycles (DOT HS-802 288). Included is an analysis, design and test of a toroidal jerk (rate of change of angular acceleration) sensor. The control system proposed by these two studies utilizes jerk as the feedback signature of impending wheel lock. Results show that the toroidal jerk sensor can be used as the critical sensor in the system while a model exists which can be used to design the device to match given requirements. Brake pressure control techniques are discussed, included are pressure bleed effects, a brake pressure replenisher, fluidic power brake unit and a jet pipe brake pressure controller. Systems analysis includes sensors, pressure control techniques, and power supplies. Recommendations are made regarding a suitable working fluid for the particular application, while a typical fluidic gain circuit is presented.
