Abstract:
A system includes a grade estimation module that receives an accelerometer value and generates a grade estimate based on the accelerometer value, wherein the accelerometer value corresponds to acceleration of a vehicle and the grade estimate corresponds to a grade of the vehicle. A mass estimation module receives the accelerometer value and generates a mass estimate based on the accelerometer value, wherein the mass estimate corresponds to a mass of the vehicle. A shift control module at least one of selects and adjusts one of a plurality of shift schedules based on at least one of the grade estimate and the mass estimate and controls a transmission of the vehicle based on the one of the plurality of shift schedules.
