摘要： A method and apparatus to control acceleration of a vehicle equipped with an electrically variable transmission and including a regenerative braking system, each are operably connected to a vehicle driveline. The method and apparatus include determining which one of a preselected shift selector position for the transmission is commanded, and determining operator demand for acceleration, using inputs from throttle pedal and brake pedal. Vehicle acceleration is measured, and magnitude of commanded torque transferred from the electrically variable transmission and the regenerative braking system to the vehicle driveline is controlled based upon the commanded preselected shift selector position, the operator demand for acceleration, and the measured vehicle acceleration.

摘要： An improved shift pattern control in which successive upshifting and downshifting is avoided in conditions of above normal loading by inhibiting upshifting to a speed ratio having insufficient gradeability in relation to a measure of the actual loading. In essence, the control continually monitors the gradeability of the various forward speed ratios of the transmission in relation to a measure of the actual grade load to determine their excess gradeability, and removes from the shift pattern those speed ratios having insufficient excess gradeability. This ensures that the transmission will never be upshifted to a speed ratio that has insufficient gradeability for the given driving condition, thereby eliminating the successive upshifting and downshifting which occurs with conventional shift controls.

摘要： An improved powertrain control which recognizes the occurrence of engine speed flare during low torque upshifting, and effectively converts the shift to a power-off upshift via an override of the normal engine torque management controls. The engine spark timing is retarded by a predetermined amount during every power-on upshift for the reasons described above. However, when the occurrence of engine flare is detected, the control increases the spark retard to a maximum valve, substantially eliminating the transmission input torque. As the on-coming element smoothly applies and decelerates the input, the flare condition terminates, and the spark timing is returned to the predetermined amount for completion of the shift.

摘要： An open-loop clutch-to-clutch shift control system wherein the overlap between off-going and on-coming clutches in an upshift is regulated in accordance with a confidence term determined through a self-estimation by the control system of its ability to accurately determine the on-coming clutch fill time, and thus, its ability to effect a precise exchange of the off-going and on-coming clutches with little or no overlap. Under certain conditions, the confidence level is assumed to be low, and the clutches are controlled to result in a relatively high level of overlap. As the level of confidence improves, the timing of the clutch exchange is adjusted to reduce the level of overlap. When the level of confidence is high, the exchange of clutches is effected with almost no overlap.

摘要： A mechanical clutch is provided to selectively interconnect a forward or reverse gear member to a transmission shaft. The clutch is operated by a servo piston and fork structure. The servo piston is slidably disposed in a housing and urged in the forward select position by a spring. The housing and servo piston cooperate to define two fluid chambers which are maintained in a separated condition when the forward select position is established. One chamber is in fluid communication with a fluid system that is controlled to provide fluid at two distinct pressure levels, depending upon various vehicle operating parameters. The other chamber is connected with a selectively engageable fluid operated friction clutch which is effective to assist in establishing at least the reverse drive ratio within the transmission. The lowest level of fluid pressure in the one chamber is not sufficient to cause the piston to overcome the spring force and thereby move the clutch to the reverse select position. The second pressure level is, however, sufficient to cause such movement. In the reverse select position, the chambers are fluidly interconnected and the fluid clutch can be engaged by the fluid pressure supplied through the second chamber from the first chamber.

摘要： An improved powertrain control which recognizes the occurrence of positive engine torque caused by accelerator walk-in by the operator during coast-sync-coast downshift, and effectively prevents or arrests speed flare via engine torque management controls. The engine spark timing is normally not responsive to coast-sync-coast downshift conditions, however, when the occurrence of accelerator walk-in results in excessive positive engine torque likely to cause, or actually causing, engine speed flare is detected, spark retard is controlled to a predetermined value, thereby controlling the transmission input torque and allowing smooth application of the on-coming element for completion of the shift.
