TRANSMISSION CONTROL APPARATUS FOR REGULATING ENGAGEMENT OF A FLUID OPERATED TORQUE TRANSMITTING DEVICE |
摘要 |
An electronically mechanized control apparatus for regulating the engagement rate or stroke time of a fluid operated torque transmitting device (14), wherein the flow rate is controlled with a flow control device having a low flow state (80) and a high flow state (80,86). The shift is initiated with the flow control device in the high flow state. After a variable delay time, the flow control valve (84) is activated to the low flow state to complete the shift. The delay time is scheduled as an open-loop function of various system parameters to achieve the optimum amount of overlap between the on-coming and off-going torque transmitting devices. An adaptive learning control superimposed on the open-loop control trims the open-loop schedule to compensate for changes in system parameters or tolerance variations which affect the stroke time. <IMAGE> |
