Estimating the term…
A vehicle includes an engine having a crankshaft which rotates at an engine speed, a transmission having a rotatable input member, a transmission control module (TC), and an engine control module (ECM) in communication with the TCM. The TCM is programmed to execute a transmission-to-engine speed monitoring and control method which includes transmitting an engine speed request to the ECM which requests a positive increase in the engine speed, and terminating the request when the request is active for more than a first calibrated timeout duration. The TCM also terminates the request when the request is active for more than a second calibrated duration that is less than the first calibrated duration, the transmission is not in neutral, and both a shift of the transmission and an acceleration of the input member are not active.
A vehicle comprising:
A transmission assembly for use in a vehicle having an engine control module (ECM) and an engine, wherein the engine includes a crankshaft which rotates at an engine speed, the transmission assembly comprising:
A method for use in a vehicle having a transmission with an input member, a transmission control module (TCM), an engine, and an engine control module (ECM), wherein the engine includes a crankshaft which rotates at an engine speed, the method comprising:
