摘要： A method for determining the onset of positive torque through an automatic transmission (the power-on point), includes saving engine torque magnitudes within a specified tolerance of each other and within a adaptive limits, the highest torque value of the sampled torque magnitudes being stored in memory. The saved value plus a calibrated safety margin is used to compare to the calculated transmission input torque. If the input torque is higher, the powertrain is considered “power-on.” In addition to the safety margin, other calibratable adder torque values can be used to compensate for air conditioning, electrical loads, temperature, etc. If the samples fall below the lower adaptive limit, the lower limit is used plus any torque adders. If the adaptive samples are above the adaptive limit, the upper adaptive limit is used without any torque adders. A calibrated baseline torque value is used for power-on determination until enough valid samples are obtained.
摘要翻译：通过自动变速器（通电点）确定正转矩的开始的方法包括将发动机扭矩幅值保持在彼此的指定公差内并在自适应限制内，所存储的采样转矩幅度的最大扭矩值在记忆中。保存的值加上校准的安全余量用于与计算的变速箱输入扭矩进行比较。如果输入转矩较高，则动力总成被认为是“上电”。除了安全裕度外，还可以使用其他可校准的加法器扭矩值来补偿空调，电气负载，温度等。如果样品低于较低的自适应极限，则使用下限加上任何扭矩加法器。如果自适应样本高于自适应极限，则使用上限自适应极限，而不使用任何扭矩加法器。校正的基线扭矩值用于上电确定，直到获得足够的有效样本。

摘要： A method and apparatus are provided to determine a failure of an automatic transmission temperature sensor in an automobile. The apparatus detects a start-up of the vehicle. A sensor detects the transmission fluid temperature. The transmission fluid temperature at start-up is checked to see if the temperature is below a first predetermined temperature or above a second predetermined temperature. If the sensor does not detect a predetermined change in temperature during operation of the vehicle after it is determined the transmission fluid temperature at start-up is above the first predetermined or below the second predetermined temperature, the sensor has failed.

摘要： A shift control and shift strategy for an automatic transmission in an automotive vehicle driveline wherein the automatic ratio shift schedule can be disabled selectively to accommodate a manual ratio shift control. A driver-operated mode selection switch permits the operator to select normal automatic ratio control or a launch-assist mode during operation in the normal ratio shift mode. Ratio changes occur in response to driveline operating variables in a vehicle launch-assist mode. The transmission control system is commanded to effect a high speed ratio when the vehicle is stationary with the brakes applied. The operating mode defaults to a normal ratio shift mode as the operator releases the wheel brakes. In an alternative embodiment of the invention, the control includes multiple enable switches for achieving manual selection of the ratios when a manual upshift sequence is desired.

摘要： A method and system for testing the functionality of a solenoid used to change the apply state of a torque converter clutch in a vehicle having an electronic control unit and a driveline system including an engine, a transmission, a torque converter. A first torque converter speed ratio is established. The commanded apply state of the torque converter clutch is determined, then a second torque converter speed ratio is calculated using engine speed and output shaft speed. The functionality of the torque converter clutch solenoid is established by determining whether the torque converter clutch solenoid has changed the applied state of the torque converter clutch by performing a comparison of the first and second torque converter speed ratios.
