摘要： A system for scheduling gear ratio changes in an automatic transmission and controlling operation of a torque converter bypass clutch includes a microprocessor; electronic memory containing control algorithms, lookup tables, functions and constants; solenoid-operated shift valves, a variable force solenoid, friction clutches, brakes and sensors, and planetary gear units. A table of calibrated performance weighting factors (PWF) is used to alter reference schedules of gear ratio changes based on the extent to which high performance operation is desired rather than economy operation. The PWFs are used to adjust gear shift points based on inferences drawn from engine throttle position and time rate of change of throttle position. Hydraulic pressure supplied to the friction elements and the schedule of unlocked and modulated operation of the torque converter are adjusted from reference schedules and pressures on the basis of PWF values.

摘要： A control system for reducing the torque applied to an automotive engine when the vehicle is idling and the transmission is set for operation in an acceptable drive range includes sensors to determine the manual gear selector position, output shaft speed, engine speed, turbine speed, and the throttle valve position. A solenoid operated valve opens and closes a source of high pressure fluid to a clutch whose engagement is required to transmit torque through the transmission from the engine to the drive wheels. An electronic computer is supplied with the digital equivalent of the shaft speeds, the position of the gear selector and of the throttle. An equation for determining the duty cycle of the solenoid valve coils is repetitively calculated through the use of a computer program algorithm. The equation corrects a previously calculated duty cycle with feedback error and terms that are proportional to the magnitude of the present error and the magnitude of the previous error.
