SYSTEM AND METHOD FOR DRIVING MODE CONTROL OF HYBRID VEHICLE

摘要

A driving mode control system of a hybrid vehicle includes a driving information detecting unit which detects information of manipulation of an accelerator pedal by a driver and an operating state of an electric load, a second motor which generates a starting torque in accordance with a control signal which converts a driving state into a hybrid electric vehicle (HEV) mode to start the engine, and a hybrid controller which calculates a system demand power by a sum of a driver demand power which is calculated by a mapping value by the accelerator pedal manipulation information and the electric load demand power in accordance with the operating state of the electric load to determine a time to connect the engine power in accordance with a predetermined reference value setting.

1. A driving mode control system of a hybrid vehicle, the system comprising:
a driving information detecting unit which detects information of manipulation of an accelerator pedal by a driver when the hybrid vehicle moves and an operating state of an electric load; a second motor which generates a starting torque in accordance with a control signal which converts a driving state into a hybrid electric vehicle (HEV) mode to start the engine; and a hybrid controller which calculates a system demand power by a sum of a driver demand power which is calculated by a mapping value by the accelerator pedal manipulation information and the electric load demand power in accordance with the operating state of the electric field load to determine a time to connect the engine power in accordance with a predetermined reference value setting, wherein when the system demand power exceeds a set upper limit power reference value (P-threshold 1), the hybrid controller controls to convert a driving mode into the HEV mode, and in a low power demand condition where the system demand power exceeds a lower limit power reference value (P-threshold 2), when an accumulated demand energy in which the system demand power is accumulated exceeds a predetermined energy reference value (E-threshold), convert the driving mode into the HEV mode.
