Abstract: A system and method for reducing wheel spin of a vehicle on slippery surfaces wherein the wheel spin is reduced by regulating the engagement of the clutches in a multiple clutch transmission of the vehicle. Upon detection by a controller of an abrupt acceleration by a driven wheel, the controller partially engages the transmission clutch which is currently disengaged, thus increasing the load on the engine and reducing the wheel spin while maintaining the drive train torque path through the previously engaged transmission clutch. Additionally, engine output is decreased upon detection of wheel spin to reduce the wear on the partially engaged clutch.

Abstract: During a shift operation, a time interval TT which is required to switch a mechanical gear ratio is detected. To bring it into coincidence with a reference value, the duty cycle with which a linear solenoid valve SL6 which determines a back pressure on an accumulator is energized is adjusted. The duty cycle is adjusted in accordance with an oil temperature, a throttle valve opening and a shift mode of an automatic transmission in order to prevent the occurrence of shift shocks as a result of a variation in the shift response of the automatic transmission from transmission to transmission or with time.

Abstract: An adaptive correction of an inappropriate shift operation is disclosed. During a power-off upshift, a variation in output torque of the transmission output shaft is detected. A decision is made based on this output torque variation whether or not the power-off 1-2 upshift has been effected in a predetermined appropriate manner, and a timing at which an on-coming friction device to be engaged during the power-off upshift is corrected based on the decision made. Thus, the shift operation during the next occurrence of a power-off upshift of the same type is effected in the appropriate manner.

Abstract: The rotational speed of an engine Ne and a drum rotational speed Nt of a clutch Cl are compared against each other to determine a power on/off. For a 2.fwdarw.3 and a 2.fwdarw.4 shift in the power off condition, a timing solenoid SL5 is turned on (duty cycle of 100%) to accelerate the termination of a preceding speed range, thus increasing a time delay between such termination and the activation of a new speed range to be established. For other shifts, a time difference between the termination of a preceding speed range and the activation of a new speed range to be established is adjusted, by energizing the solenoid SL5 in accordance with the throttle opening .theta. and the vehicle speed No such that SL5 is energized with a high duty cycle for a longer .theta. and with a low duty cycle for a smaller .theta..

Abstract: An improved control, which dynamically adjusts the shift control parameters in response to the driving habits of the operator, as judged by an indication of the average peak acceleration during specified operation of the vehicle. To determine the indication of average peak acceleration, the longitudinal acceleration of the vehicle is continuously determined in the course of vehicle operation. The peak acceleration values occurring in successive ratio-dependent time intervals are identified and accumulated to form cumulative and average peak acceleration terms. The average peak acceleration term is used to form a dynamic shift factor which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a continum of shift control parameters uniquely suited to the driving style of the operator of the vehicle.
