Abstract:
A control system for a hybrid vehicle. The system comprises a controller configured to cause a net negative drive torque to be applied by an engine or an electric machine of the vehicle to the input shaft of a transmission in a direction opposing travel of the vehicle to effect braking, determine when a transmission gear shift is about to occur requiring a non-negative torque to be applied at the input shaft, and when the gear shift is about to occur, temporarily cause a net non-negative drive torque to be applied to the input shaft by causing the electric machine to apply a positive drive torque to the input shaft to compensate for negative torque applied by the engine, and cause brake force to be applied by a braking system to compensate for a reduction in negative drive torque applied to the input shaft, while the gear shift occurs.
