Hybrid electric vehicle and engine start information display method therefor

A hybrid electric vehicle, comprising:

• a hybrid control unit configured to determine a likelihood of engine start for each of a plurality of reasons for engine start and determine a reason for engine start having a highest likelihood of engine start from among the plurality of reasons for engine start and engine start information including the highest likelihood of engine start in consideration of a type of at least one reason for engine start and a level of the likelihood of engine start;
• and
• a display configured to display the engine start information;
• wherein, when an engine start request is generated due to a factor having only a single on/off criterion from among the plurality of reasons for engine start, the hybrid control unit is configured to determine a likelihood of an engine start delay according to the engine start request;
• and
• wherein the hybrid control unit is configured to determine a delayable time when the engine start delay is possible as a result of the likelihood of the engine start delay and increase the likelihood of engine start for the reason for engine start having only the single on/off criterion to a maximum value over time for the delayable time, or when the engine start delay is impossible as a result of the likelihood of the engine start delay, the hybrid control unit is configured to increase the likelihood of engine start for the reason for engine start having only the single on/off criterion to a maximum value over time for a predetermined minimum reference time.

A method for providing engine start information for a hybrid electric vehicle, the method comprising:

• determining a likelihood of engine start for each of a plurality of reasons for engine start;
• when an engine start request is generated due to a factor having only a single on/off criterion from among the plurality of reasons for engine start, determining a likelihood of engine start delay according to the engine start request;
• determining a delayable time when the engine start delay is possible as a result of determining the likelihood of the engine start delay;
• and
• displaying a reason for engine start having a highest likelihood of engine start from among the plurality of reasons for engine start and engine start information including the highest likelihood of engine start in consideration of a type of at least one reason for engine start and a level of the likelihood of engine start, wherein, when the engine start delay is impossible as a result of determining the likelihood of the engine start delay, displaying the reason comprises increasing the likelihood of engine start for the reason for engine start having only the single on/off criterion to a maximum value over time for a predetermined minimum reference time.
