摘要： A method of providing guidance for a charging amount of an eco-friendly vehicle includes: predicting a driving energy for each section of a predicted travel route that is divided by a plurality of sections; calculating a battery input and output energy for each section based on the driving energy for each section; and determining a start SoC for minimizing a total change amount of a SoC that is sequentially changed in a section order when driving along the predicted travel route by applying a charge and discharge efficiency depending on a current SoC of a battery at each section to the battery input and output energy for each section.

摘要： A method for controlling a hybrid vehicle is disclosed. The method comprises calculating, for a low-emission area on the vehicle's current travel, a first energy to travel the low-emission area in a first driving mode, determining whether the hybrid vehicle is capable of traveling the low-emission area in the first driving mode using current energy of a vehicle battery, and when it is determined that the hybrid vehicle is incapable of traveling the low-emission area in the first driving mode using current energy of the vehicle batter, initiating a battery charging operation before the vehicle enters the emission-restricted area.

摘要： A method of controlling a mode transition of a hybrid vehicle includes determining whether a mode transition from a first mode to a second mode is required based on a first torque, the first torque being a current required torque. A second torque, which is a required torque expected to be generated at a near-future time from a current time, is also determined. A predicted gear shift time point and a predicted engagement time point of an engine clutch are determined based on the second torque. The mode transition to the second mode is performed when it is determined that the mode transition to the second mode is required and the predicted engagement time point is earlier than the predicted gear shift time point.

摘要： A method of performing temperature control of a hybrid vehicle implements a mode change control method capable of efficiently performing heating in cold weather by predicting a stop of the hybrid vehicle. The method includes receiving an engine operation request from a full automatic temperature control (FATC) unit, determining whether to enter a first hybrid electric vehicle (HEV) mode utilizing engine power as driving force, determining whether a predicted stop time is equal to or less than a predetermined time, when entry into the first HEV mode is impossible, and disallowing entry into a second HEV mode utilizing engine power for generation of electricity, when the predicted stop time is equal to or less than the predetermined time.

摘要： A hybrid vehicle and a method of controlling a charge mode therefor are provided. The control method includes determining a first torque, which is a currently requested torque and determining a second torque, which is a predicted requested torque that is predicted to be generated in the near future from the present time, or predicted acceleration. Additionally, the method includes releasing a lock-up charge mode when the first torque is less than a first threshold value relevant to a reference for determining coasting driving and the second torque or the predicted acceleration is less than a second threshold value relevant to a driving mode change reference.

摘要： An engine control apparatus and an engine control method are provided. The engine control apparatus includes an accelerator pedal position sensor that measures a position of an accelerator pedal in response to an operation of the accelerator pedal. Additionally, a vehicle controller verifies whether a driver demand torque is equal to or greater than a current engine torque when the position of the accelerator pedal is deviated from a reference position while an engine is operated in a part load mode and determines whether to permit a transition of an engine mode of the engine to a full load mode. An engine controller then transitions the engine mode to the full load mode from the part load mode in response to a control of the vehicle controller.

摘要： A driving control method of a hybrid vehicle is provided. The method includes acquiring link information on each of a current link in which the vehicle currently travels in an electric vehicle (EV) mode and a forward link connected to the current link ahead of the current link. A first average driving load of the current line and a second average driving load of the forward link are calculated based on the acquired link information. When the second average driving load is greater than the first average driving load a minimum required state of charge (SoC) based on the second average driving load and a preset driving mode switch reference are determined.
