System and method for improving the vehicle feel, fuel efficiency and performance of a hybrid vehicle
Abstract:
A system for providing a smoother vehicle response when transitioning a hybrid vehicle having a transmission, a battery and a fuel converter from an EV driving mode to a HV driving mode. The system includes a memory for storing an amount of force to be applied to the transmission for a given pedal input and a given vehicle speed. The system also includes a BMU for determining a state of charge of the battery and for determining a proportional scaling number based on the state of charge. The system also includes an ECU for determining a scaled drive force based on the amount of force to be applied to the transmission and the proportional scaling number and for controlling the utilization of the battery and the fuel converter based on the scaled drive force when the state of charge of the battery is within a low power range.
