    摘要: A method of adapting transmission controls to locate synchronizer touch points in an automated layshaft transmission. This method may include actuating a motor to move a shift drum along a layshaft at an essentially constant speed; measuring a feedback current as the motor moves the shift drum; detecting a first spike in feedback current adjacent to a second spike in feedback current for a gear; determining a shift drum angle for the first spike; and adjusting a transmission controller to set a synchronizer touch point at a shift drum angle adjacent to the first feedback current spike for the gear.

    摘要: A method for controlling a vehicle driveline includes determining, for current vehicle operating conditions, an initial engine output torque, at which the driveline meets predetermined structural criteria, establishing a factor that varies with torque converter slip, determining an engine torque limit by multiplying the factor corresponding to a current torque converter slip by the initial engine output torque, and limiting torque produced by an engine connected to the driveline to the engine torque limit.

    摘要: A method for controlling speed of an input shaft to a hydraulically actuated clutch that includes a hydraulic balance dam volume includes determining a limit speed of the input shaft that varies as a function of time during a predetermined period after the clutch starts rotation and that causes a servo piston for actuating the clutch to move toward an engaged position, rotating the input shaft during the period, limiting a speed of the input shaft during said period to a determined limit speed corresponding to a current time after beginning the period, and allowing the speed of the input shaft to increase to a speed greater than the determined limit speed after expiration of the period.
