Abstract:
1. A method of determination of a driving mode of a hybrid vehicle, the method being executed by a hybrid control unit (HCU) and comprising the steps of: modeling a PNGV (Partnership for a New Generation of Vehicles) systems analysis toolkit (PSAT) to calculate reserved power to drive a motor; determining whether the driving mode of the hybrid vehicle is consistent with an electric vehicle (LV) mode or not, using the power reserved to drive the motor, which has been calculated using the PSAT model; if the driving mode is not consistent with the EV mode, determining whether or not the driving mode is consistent with a maximum (MAX) torque mode; and if the driving mode is not consistent with the MAX torque mode, determining that driving mode to be a hybrid-electric vehicle (HEV) mode; and wherein said step of determining whether the driving mode is consistent with the MAX torque mode comprises the steps of:
