    摘要： A pneumatic throttle valve actuator for an automatic power transmission mechanism for use with a supercharged or turbocharged internal combustion engine wherein the relationship between manifold pressure and actuator force is changed when the engine manifold pressure changes from a positive pressure to a negative pressure or vice-versa. A correct shift point signal and a correct pressure regulator output thus are maintained regardless of whether the turbocharger or supercharger is active or inactive.

    摘要： A system and method for controlling gear ratio changes in an automatic transmission includes an electronic microprocessor, an electronic memory accessible to the microprocessor, solenoid-operated shift valves, pressure actuated friction clutches and brakes, a variable force solenoid-operated valve, a torque converter bypass friction clutch, and control algorithms that produce output signals to control the state of the solenoid-operated valves. The vehicle speed and engine speed at which upshifts and downshifts occur, according to a standard gear shift schedule, is compensated for loss of engine torque at conditions that differ from the conditions at which a reference shift schedule is defined. Vehicle speed is compensated for torque variation with reference to the ratio of current calculated engine torque divided by current engine output torque.

    摘要： An electronic control system for operating a torque converter clutch during a transmission gearshift includes a vehicle speed sensor and engine speed sensor, a hydrodynamic torque converter located between the engine and the transmission, a solenoid-operated hydraulic valve, which engages and disengages the torque converter clutch in accordance with the energized and deenergized state of the solenoid in accordance with the logic of the control system. The converter clutch is locked while operating in the original gear ratio, then unlocks during the gearshift, and relocks after the upshift is completed. The speed ratio of the torque converter is rapidly determined in terms of the number of clock ticks occurring between pulses whose frequency is proportional to engine speed. The current speed ratio is determined during interrupts occurring at short intervals during a background pass.

    摘要： A system and method for controlling the bypass clutch of an automatic transmission includes an electronic microprocessor, an electronic memory accessible to the microprocessor, solenoid-operated bypass valve, pressure actuated bypass clutche, a variable force solenoid-operated bypass valve, a torque converter bypass friction clutch, and control algorithms that produce output signals to control the state of the solenoid-operated valve. The vehicle speed at which the bypass clutch engages and disengages, according to a reference schedule, is compensated for loss of engine torque at conditions that differ from the conditions at which the reference schedule is defined. Vehicle speed is compensated for torque variation with reference to the ratio of current calculated engine torque divided by current engine output torque.
