摘要： A control strategy for a multiple-ratio transmission for an automotive vehicle comprising a shift valve system that responds to shift valve signals developed by a microprocessor controller, the controller being in communication with engine sensors indicating engine operating variables and transmission sensors indicating transmission operating variables, the shift valve system responding to shift signals developed by the microprocessor during coasting downshift of the vehicle from one gear ratio to a lower gear ratio with a closed engine throttle whereby torque reversals are avoided during coast-down, thereby eliminating inertia torque changes to improve the smoothness of coasting downshifts during cold engine operation.

摘要： An executed time of a backward slipping moderation control is counted by a timer, and after a predetermined period of time is elapsed, the control is terminated. Upon the termination of the control, a control of operation of a brake actuator is executed so that a wheel cylinder pressure is decreased with a gentle slope in comparison with a normal operation of the brake actuator for terminating the control. Where the backward slipping moderation control is executed by controlling a brake fluid pressure of the brake actuator, an acceleration &agr; of a vehicle is estimated. If the acceleration is larger than a predetermined value, a target pressure P is increased, thus generating a relatively large braking force.

摘要： An electronic control system for an automatic transmission has an electronic control unit including a CPU and a memory. The control program is programmed based on an object-oriented programming. An object such as a domain control unit or individual control parts are provided for driving a corresponding linear solenoid valve. A shift request output unit determines types of required shift and outputs a shift request message including the shift type. The domain control unit determines a method to be executed in response to the shift type ID. Preferably, the shift request output unit further determines whether the shift is a single shift or a multiple shift and whether the shift is a normal shift or a special shift. These determination results are also included in the shift request message, so that the domain control unit varies the method to control the linear solenoid valves. The control program can be revised in a simple manner by revising only the domain control unit and individual control parts corresponding to the linear solenoid valve having the changed specification.

摘要： In an automatic transmission, transient control of the working oil pressures for friction elements whose state is to be switched is normally carried out in accordance with a degree of shift development determined based on at least a vehicle speed. When the vehicle speed is too low to provide determination of the degree of shift development, transient control of the working oil pressures for the friction elements is carried out in accordance with elapsed time from shift instead of normal transient control.

摘要： A shift control method for an automatic transmission improves shift feel and acceleration characteristics by determining if 4→3 shifting is required during lift-foot-up 3→4 shift control, and if so, the method controls a number of solenoid valves and friction elements with input from a plurality of sensors that stop the lift-foot-up 3→4 shift when the accelerator pedal is again depressed after being released.
