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.

摘要： The present invention provides a means to learn and accommodate the amount of air that needs to be purged from a clutch circuit after being off for a predetermined time. The scheme helps to maintain proper control timing as necessary for good shift quality and clutch durability and further helps to minimize unnecessary delays in clutch application. Once the air has been purged, then normal control timing can be resumed.

摘要： A novel transmission is provided that has a first, second, third and fourth gear, wherein said second gear includes two alternate and selectable speed ratios. The primary speed ratio of the second gear is used during upshifts and downshifts of adjacent gears. The alternate speed ratio of the second gear is utilized exclusively during downshifts from non-adjacent gears and may also be utilized during a downshift from the third gear depending on certain conditions and parameters. The primary speed ratio is larger than the alternate speed ratio of the second gear to provide better acceleration characteristics of the transmission during upshifting. The smaller alternate speed ratio of the second gear can provide smoother downshifts because of the less abrupt speed ratio change from the higher gears. Also, a method for controlling the gear selection of an automatic transmission having a plurality of gears is provided, wherein one position includes two speed ratios.
摘要翻译：提供了一种具有第一，第二，第三和第四齿轮的新型变速器，其中所述第二齿轮包括两个交替和可选择的变速比。在相邻齿轮的升档和降档期间使用第二档的主变速比。第二齿轮的交替速比仅在来自不相邻的齿轮的降挡期间被使用，并且还可以在根据某些条件和参数从三档进行降档时使用。主变速比大于第二档的交替速比，以提高换档期间变速器的加速特性。由于与较高档位的转速比变化较小，所以第二档的较小的交替变速比可以提供更平滑的降档。此外，提供了一种用于控制具有多个齿轮的自动变速器的档位选择的方法，其中一个位置包括两个速比。

摘要： A sensing system for detecting the position of a manually operated shift lever in an automatic transmission. The sensing system includes a plate member movable in response to movement of a shift lever. The plate member includes a generally flat contact surface having a predetermined pattern of electrically conductive and non-conductive areas. An electrical sensor unit is mounted in the transmission and positioned to communicate with the contact surface of the plate member. At least five electrical contact members engage the conductive and non-conductive areas on the contact surface generate binary codes having combinations that are indicative of the shift lever position in each of the predetermined operating modes. The engagement between the contact members and the contact surface further generates at least four unique binary codes indicative of the transitions between the predetermined operating modes. These four unique binary codes indicate to a controller the specific transition zone the shift lever is positioned within.

摘要： An automatic transmission control system is provided with extreme cold logic wherein when the transmission oil temperature is below a predetermined temperature so as to cause the transmission oil to have extremely viscus characteristics, the transmission prevents faulty shifting by limiting shifts between first and third gears. The first gear is obtained by application of a single hydraulically controlled clutch element in combination with a freewheel clutch element while the third gear operation can be obtained by engagement of a second clutch element in combination with the first clutch element. Since the shift between first and third gears only requires the application of the second clutch element in combination with the already engaged first clutch element, there is no risk of torque overlap between elements.
摘要翻译：具有极冷逻辑的自动变速器控制系统，其中当变速器油温度低于预定温度以便使变速器油具有极高的特性时，变速器通过限制第一和第三档位之间的换档来防止错误的变速。通过将单个液压控制的离合器元件与自由轮离合器元件结合使用而获得第一档，同时可以通过与第一离合器元件组合地接合第二离合器元件来获得第三档操作。由于第一和第三齿轮之间的换档仅需要将第二离合器元件与已接合的第一离合器元件结合使用，所以不存在元件之间扭矩重叠的风险。
