A study was conducted of an approach to anti-lock braking for motorcycles which utilizes the rate of change of angular acceleration as a feedback signature. The front wheel braking system of a motorcycle has been modelled using computers. This modelling describes the tire as an elastic member of the braking system. The analytical model points out the advantages gained from use of the rate of change of angular acceleration (jerk) as a feedback signature. In addition, the front wheel and brake from a Kawasaki KZ-400 were placed on a drum dynamometer for study. Results substantiate the predictions of the model showing the proper change in slope of wheel angular acceleration. The technology of fluidics is suggested for implementation of the system concept. Two accelerometer concepts are discussed as well as the required circuitry and actuator. Recommendations are made as to the feasibility of each sensor and the concept as a whole.
