    摘要： A method for synchronizing a plurality of pedal position sensors in a motor vehicle. A series of voltages are accumulated from each of a plurality of pedal position sensors. Representative voltages are determined from the series of voltages. The representative voltages are assigned to linear relationships from which an offset is determined.

    摘要： The present invention provides a method for shifting from a first gear state to a second gear state which holds one element at a predetermined level until the second reaches its fill volume. In this method, one element is applied while the other element is released. The element which reaches its fill volume first is held at a control limit. This control limit is defined by a volume between the first clutch element and a predetermined point above the fill volume of the first clutch element. This clutch element is then maintained at within the control limit until the other clutch element reaches its fill volume. The maintained clutch element is then released shortly after the other clutch element has reached its fill volume. This method ensures that neither fighting or slipping occurs between the two elements.

    摘要： A method for reinitializing vehicle parameters stored in a memory of a controller in a motor vehicle after a power loss to the controller includes the steps of determining whether predetermined conditions are right for transferring at least one vehicle parameter stored in a volatile memory of a controller, transferring the vehicle parameter stored in the volatile memory to a non-volatile memory if the predetermined conditions are right for transferring the vehicle parameter, determining whether predetermined conditions are right for re-initializing the vehicle parameter after a power loss to the controller, transferring the vehicle parameter from the non-volatile memory to the volatile memory if the predetermined conditions are right for re-initializing the vehicle parameter, and initializing the vehicle parameter with a predetermined initial value stored in the non-volatile memory to the volatile memory if the predetermined conditions are not right for re-initializing the vehicle parameter.

    摘要： The present invention provides improved initial shift quality in an electronically controlled automatic transmission by enabling the friction element fill volumes to be "learned" by the transmission controller before the vehicle leaves the assembly line. An end of line (EOL) volume learn procedure is intended for final check out at car assembly or for other appropriate circumstances such as for service after a transaxle has been rebuilt or replaced, or as a diagnostic tool to help confirm an indicated condition of an element.Upon satisfaction of a set of initial conditions, an end of line volume learn procedure is initiated wherein the transmission is cycled through a number of phases, each phase generally corresponding to the application of a different friction element. In other words, each element is applied or logically turned "ON" until a predetermined change in the amount of separation between engine speed and turbine speed (slip) is identified, thereby indicating the apply point of the respective element. Various parameters are measured as each element is applied and released, these parameters being used to calculate an initial fill volume. The initial fill volume of each element is stored in RAM memory for use by the transmission controller when the vehicle is actually driven for the first time.

    摘要： A sensing system is provided for sensing the position of a manual gear select lever in an automatic transmission. The sensing system includes a plate member movable in response to movement of a shift lever and has a contact surface having a predetermined pattern of electrically conductive and non-conductive areas. An electrical sensing unit is mounted in the transmission so as to communicate with the contact surface of the plate member. A plurality of electrical contacts extend from the sensing unit to contact the conductive and non-conductive areas on the contact surface and generate binary codes in accordance with the position of the shift lever. Combinations of binary codes are provided for the operating modes and require at least two bit changes therebetween. In addition, transition codes are provided between each of the operating modes. The binary codes are provided to a transmission controller which determines the predetermined operating mode and transition modes therebetween.
