Abstract: Systems and methods for providing user-specific information to a golfer. Ball flight data associated with golf ball(s) struck by the user are obtained (e.g., via a launch monitor). A user data set is generated based upon the ball flight data. For example, the ball flight data is modeled by a simulation flight engine and the user data set provides elevation and slope information derived from the simulations. In advance of a golf shot, a line of sight distance from a current position of the user and a target is determined (e.g., rangefinder). Current conditions implicating the golf shot (e.g., elevation and slope) are determined. User-specific shot information is generated from the user data set based upon the determined line of sight distance and the current conditions and is displayed. The user-specific shot information can include adjusted current distance, club recommendation, current elevation carry distance(s), and/or current elevation shot dispersion.

Abstract: A method for controlling trapped air in a clutch of an automatic clutch-to-clutch transmission includes, calculating a pulse on time based on a clutch volume and adaptive convergence. A pulse off time is calculated based on a temperature of transmission fluid. A pulse number is calculated based on the temperature of transmission fluid. A maximum pressure is commanded to the clutch based on the pulse on time and a minimum pressure is then commanded to the clutch based on the pulse off time. A pulse counter is incremented when the pulse off time expires. The steps of commanding maximum pressure, then commanding minimum pressure, and incrementing the pulse counter are repeated until the pulse counter equals a desired pulse number.

Abstract: A control system that generates one of a normal mode and a hot mode signal to control operation of a transmission includes a calculator that calculates a predicted temperature of a torque converter and a comparator that compares the predicted temperature to a threshold temperature. A timer generates one of the normal mode and the hot mode signals based on the predicted temperature and the threshold temperature.
