ABSTRACT:
For use on a vehicle having a split torque transmission, the split torque transmission including first and second throughputs and a summing junction connected to the first and second throughputs and having a transmission output dependent upon the first and second throughputs, each throughput having an input connected to an output of the engine of the vehicle, the system including a sensor adapted to sense the output of the engine, and a controller connected to the sensor and adapted to control the second throughput dependent upon the engine output, the second throughput being controlled from a negative value cancelling the first throughput to a positive value so that the transmission output is varied from idle to a predetermined value.
