Patent ID: 8475335

Claim:
A vehicle comprising: an engine configured to be automatically restarted in response to a start signal during an engine auto-start event; a torque converter having a turbine with a measurable turbine speed; a sensor operatively connected to the turbine and configured to measure the turbine speed; a transmission having a calibrated line pressure and a plurality (n) of clutches that are engaged to execute the engine auto-start event, wherein a designated one of the plurality (n) of clutches is a designated control clutch during the engine auto-start event; a hydraulic accumulator in fluid communication with the transmission that is configured for delivering a volume of fluid under pressure to the transmission in response to the start signal; and a controller configured for: receiving the start signal; mapping the remaining (n−1) clutches of the plurality (n) of clutches to the calibrated line pressure in response to receipt of the start signal; receiving the turbine speed from the sensor; and modifying a set of clutch fill parameters which controls a fill sequence of the designated control clutch as a function of a deviation of the measured turbine speed from a theoretical no-slip turbine speed.
