  • Patent number: 11260845
    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.

  • Publication number: 20190054913
    Abstract: Some embodiments of the present invention provide control system (140) for a vehicle (100) having at least one electric machine (123C) configured to cause torque to be applied to an input shaft of a transmission (124), the control system (140) being configured to: cause a net negative drive torque to be applied, at least in part by means of the electric machine (123C), to the input shaft of the transmission (124) in a direction opposing travel of the vehicle (100) in order to effect braking; determine when a transmission gear shift is about to take place requiring a non-negative torque to be applied at the input shaft of the transmission (124); and when a net negative drive torque is being applied to the input shaft of the transmission (124) and it is determined that a gear shift is about to take place requiring a non-negative torque to be applied, temporarily cause a net non-negative drive torque to be applied to the input shaft and cause brake force to be applied to one or more wheels (111, 112, 114, 115) o
