Abstract (en)
[origin: US2011125355A1] A system for controlling change in mode of an infinitely variable transmission including a first operation mode at high torque at high speed and a second operation mode at high torque at low speed, fitted to a motor vehicle that includes at least two electric machines, with at least one internal combustion engine. The infinitely variable transmission connected mechanically to the electric machines and to the internal combustion engine determines the internal combustion engine rotation speed setpoint; calculates the difference between the internal combustion engine rotation speed setpoint and the internal combustion engine rotation speed measurement; determines torque of the first electric machine to determine a torque setpoint for the first electric machine as a function of the difference between the rotation speed setpoint of the internal combustion engine and the measured rotation speed of the internal combustion engine; determines a torque setpoint for the second electric machine as a function of the torque setpoint of the first electric machine and the driver's demand for torque. The control system can control the second electric machine so that the change in mode can be performed while the vehicle is being propelled, before and after the change in mode, under sole action of at least one electric machine.
