摘要： An anti-lock braking control system is described in which the braking pressure cycle is filtered by limiting the minimum time period of each brake pressure cycle. The period from the time a brake pressure release phase is initiated until the next brake pressure release phase is called for is timed. If the time is less than a predetermined value, the brake pressure is held constant until the minimum time period has expired.

摘要： A system and method determines the rotational speed of a rotating member by determining speed from signals having a frequency directly proportional to the rotational speed. The system provides for the estimation of rotational speed even if no speed signals are detected over a sampling interval.

摘要： A system and method for determining the rotational speed of a rotating member is described that determines speed from signals having a frequency directly proportional to the rotational speed. The speed signals are counted during each of successive sampling intervals. At the end of each sampling interval, the rotational speed is determined based on a calculation interval that is the time interval from the next-to-last speed signal generated in the prior sampling interval to the last speed signal generated and the number of speed signals occurring in the calculation interval. The resulting overlapping calculation intervals minimize the influence of one speed signal on successive determinations of rotational speed.

摘要： A method of calibrating a vehicle electrical system having a data bus includes transmitting calibration data to a calibration data device, such as a memory card, associated with an electronic device, such as a radio, simultaneous to other vehicle assembly steps; and transferring at least a portion of the calibration data from the electronic device to electronic modules coupled to the data bus upon a triggering event, such as application of electric power to the vehicle electrical system. The electronic device for transferring the calibration data includes a processor capable of being coupled to the data bus and having software capable of performing calibration procedures on the electronic modules, an interface coupled to the processor and the calibration data device and capable of receiving data from the calibration data device, and hardware and/or software for enabling the processor to transfer a portion of the data from the calibration data device through the data bus to enable the software to perform calibration procedures on the electronic modules.
