Method and system for controlling an ev mode transition in a two-mode hybrid vehicle

A method of executing an electric-only (EV) mode transition in a vehicle includes determining vehicle operating values using a control system, processing the values to identify the transition, and executing the transition to or from the first or second EV mode. The transition is executed by selectively engaging and disengaging the input brake to zero, and by using the first and/or second traction motor to synchronize slip across the input brake. When the transition is from the first to the second EV mode or vice versa, the control system may use multiple speed and torque control phases to enter multiple intermediate modes, e.g., a pair of engine-on electrically-variable transmission modes and a fixed gear mode. A vehicle includes an engine, an input brake, first and second traction motors, and a transmission driven via the motors in a first and second EV mode. The vehicle includes the control system noted above.

A family of transmission gearing arrangements produces nine forward and one reverse speed ratio by selective engagement of various combinations of three clutches or brakes. Each transmission gearing arrangement includes a front shiftable gearing arrangement configured to establish a variety of speed ratios between an intermediate shaft and an input shaft. These speed ratios include a reverse speed ratio, a zero speed ratio, two underdrive ratios, and a direct ratio. Each transmission also includes a rear shiftable gearing arrangement configured to selectively establish particular speed relationships among the input shaft, the intermediate shaft, and an output shaft. Engagement of a clutch in the rear shiftable gearing arrangement establishes an underdrive ratio between the output shaft and the intermediate shaft. Engagement of another clutch in the rear shiftable gearing arrangement constrains the speed of the input shaft to be a weighted average between the speed of the intermediate shaft and the output shaft.

When throttle valve opening degree is larger than predetermined throttle valve opening degree Y in the case where a decision on shift to gear stage at which maximum load is applied to predetermined rotary member of automatic transmission is made, the gear stage is not formed. Therefore, large load is restrained from being applied to the predetermined rotary member of the automatic transmission. Besides, gear stage that is lower in vehicle speed than the gear stage by one stage or gear stage that is higher in vehicle speed than the gear stage by one stage is formed depending on whether acceleration requirement is large or small. Therefore, driving torque corresponding to the acceleration requirement is likely to be obtained. In consequence, the load applied to the predetermined rotary member of the automatic transmission can be reduced, and feeling of strangeness can be restrained from being caused by the driving torque.

For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion.

Method to identify automatic transmission lubrication oil flow rates corresponding to a running vehicle without direct oil flow measurements

Номер: US20170261047A1

Принадлежит: FORD GLOBAL TECHNOLOGIES LLC

A method of determining automatic transmission lubrication fluid flow rates corresponding to a running vehicle without direct oil flow measurements is disclosed. A set of in-vehicle clutch torques for a chosen clutch pack during a gear shift event for a set of shift conditions is obtained. A series of bench tests at various clutch-pack clearances and oil-flow rates for the set of shift conditions are performed. The clearances and oil-flow rates are adjusted in response to the measured magnitudes exceeding thresholds. In-vehicle transmission lubrication oil-flow rates are estimated at the chosen clutch pack for the set of shift conditions when the bench-test and in-vehicle clutch torques are less than the thresholds. The steps are reproduced for other engine conditions and fluid temperatures corresponding to other transmission gear positions. A functional map of in-vehicle oil flow rates are produced, and the transmission is adjusted based on the map.

In an automatic transmission, the control part controls the engaging mechanisms and recognizes the rotational speed of a drive source and a stop request for the drive source. The automatic transmission changes the rotational speed of the input member to transmission gear ratios by the planetary gear mechanism and the engaging mechanisms so as to freely output the rotation from the output member. The engaging mechanisms include a switching mechanism switchable between a fixed state and a reverse rotation preventing state in which a normal rotation of a corresponding element among the elements of the planetary gear mechanism is allowed and a reverse rotation thereof is prevented. The control part switches the switching mechanism in a state in which the stop request for the drive source is not recognized and the rotational speed of the drive source is equal to or greater than a predetermined value.
