Abstract
A hybrid electric vehicle controlling a fuel injection point-in-time and a method of controlling driving of the hybrid electric vehicle such that fuel efficiency is improved when engine start is required. The method of controlling driving of the hybrid electric vehicle may include: inhibiting engine injection when there is an engine start request and a control entry condition is satisfied, performing the engine injection when an injection allowable condition is satisfied with the engine injection inhibited, and performing reaction force control along with the engine injection through a first motor directly connected to the engine.
Claims19
A method of controlling driving of a hybrid electric vehicle, the method comprising:
- inhibiting engine injection when there is an engine start request and a control entry condition is satisfied;
- performing the engine injection when an injection allowable condition is satisfied with the engine injection inhibited;
- and
- performing a reaction force control along with the engine injection through a first motor directly connected to the engine,
- wherein the control entry condition includes a powertrain mode condition, and
- wherein the powertrain mode condition is determined based on whether an engine clutch is engaged so as to determine whether to enter an injection control that performs the reaction force control through the first motor.
A non-transitory computer-readable recording medium having a program recorded thereon, the program to direct a processor to perform acts of:
- inhibiting engine injection when there is an engine start request and a control entry condition is satisfied;
- performing the engine injection when an injection allowable condition is satisfied with the engine injection inhibited;
- and
- performing a reaction force control along with the engine injection through a first motor directly connected to the engine,
- wherein the control entry condition includes a powertrain mode condition, and
- wherein the powertrain mode condition is determined based on whether an engine clutch is engaged so as to determine whether to enter an injection control that performs the reaction force control through the first motor.
A hybrid electric vehicle comprising:
- a first motor;
- an engine directly connected to the first motor;
- a second motor directly connected to an input side of a transmission;
- an engine clutch configured to selectively connect the engine and the second motor to each other;
- and
- a control unit configured to:
- inhibit engine injection when there is an engine start request and a control entry condition is satisfied,
- allow the engine injection when an injection allowable condition is satisfied with the engine injection inhibited, and
- perform a reaction force control along with the engine injection through the first motor,
- wherein the control entry condition includes a powertrain mode condition, and a State Of Charge (SOC) condition of a battery, and
- wherein the powertrain mode condition is determined based on whether an engine clutch is engaged so as to determine whether to enter an injection control that performs the reaction force control through the first motor.
