摘要： A digital communication circuit that avoids bit collisions between an external communication device and a controller that communicate to each other through a bi-directional serial communication link is disclosed. The digital communication circuit includes digital circuitry that receives and transmits a digital communication signal. A detection circuit detects when a digital communication signal is being received. And delay circuitry receives the transmitted digital communication signal and responsively produces a delay signal to delay the detection of the received digital communication signal.

摘要： A communications network is adapted to provide communication between control modules on a vehicle. Each control module includes a first and second transceiver. A control module checks for the presence of a data message from another control module before transmitting a data message. If there is no other data message present, the control module transmits the data message around the network in both directions using the first and second transceivers. The other control modules receive the data message from the previous control module and pass the data message to the next control module in the network.

摘要： The present invention is directed toward determining when a clutch of an automatic transmission substantially fills with fluid. Once it is accurately determined when a clutch fills with fluid, then control over the transmission shifting may reliably be performed. The present invention determines when an on-coming speed clutch substantially fills with fluid in response to determining when an off-going speed clutch releases. Further, the present invention determines when an on-coming direction clutch substantially fills with fluid in response to determining when the torque converter output torque suddenly changes.

摘要： The present invention relates to an adaptive control method for an automatic transmission. The method includes the steps of:(a) commanding a predetermined clutch to fill in accordance with a plurality of clutch fill parameters;(b) determining the actual time to completely fill the clutch;(c) comparing the actual fill time with a predetermined fill time; and(d) adjusting at least one of the plurality of clutch fill parameters in response to the comparison in order to modify the clutch fill period during subsequent shifts to the predetermined clutch. Accordingly, the present invention adapts future shifts based on past shifts to improve the shift quality of the transmission.
