  • Method of optimizing vehicle performance based on countershaft acceleration
    Patent number: 10174694
    Abstract: The present disclosure provides a method of controlling input torque of a powered vehicle. The vehicle includes a transmission having an input shaft, an output shaft, and a countershaft. The method includes providing input torque to the input shaft, determining a rotational acceleration of the countershaft, and measuring vehicle speed. The method also includes determining a threshold based on the measured vehicle speed. The measured countershaft acceleration is compared to the threshold and the input torque is controlled based on the result of the comparison.
    Type: Grant

  • Oil level measurement system and method
    Patent number: 8941504
    Abstract: The present invention provides a method of determining if a fluid level in a transmission is satisfactory. The transmission includes a controller and is coupled to a powered vehicle. The method includes measuring a grade of the surface upon which the vehicle is positioned with an inclinometer and measuring the fluid level in the transmission with a fluid sensor. The method also includes communicating the measured grade and measured fluid level to the controller and determining a fluid level threshold based on the measured grade. The measured fluid level and fluid level threshold are compared and a determination is made if the measured fluid level is satisfactory based on the comparison.
