Abstract
Method and system for testing components, such as a motor, of a vehicular system capable of controlling the relative slip between a vehicle wheel and a road surface, for functionality prior to performing antilock functions utilizing a progressively increasing energization duty cycle, so as to minimize perception of noise by the vehicle operator by minimizing motor energization duration and minimizing peak motor rotational speed. The method includes energizing the motor successively with a plurality of electrical signals, each electrical signal being applied to the motor for a predetermined period of time and having at least one pulse having a width which is progressively increased with respect to the width of the at least one pulse of the previous electrical signal. Each pulse has a width sufficiently long to permit motor operation to test functionality and yet sufficiently short so that the noise associated with the operating motor during this test is minimized.
