ABSTRACT:
A method and apparatus for selecting a transmission starting gear based on calculated gross vehicle weight is disclosed. The vehicle speed and grade are monitored by sensors which provide data to a computer. The computer is programmed to calculate vehicle acceleration from the sensed speed and to adjust the acceleration value so as to eliminate the effect of grade. The gross vehicle weight is then calculated from the adjusted acceleration value. Based on the calculated gross vehicle weight and the existing grade, an appropriate starting gear is automatically selected by the computer from a look-up table stored in memory.
