Hybrid electric vehicle and control method of the same
Execution of control for first spot region of performing traveling by controlling an engine and a motor such that the electricity storage ratio of an electricity storage apparatus becomes smaller before a first spot region presumed or set as a spot or a region preferred to be reached in a state in which the electricity storage ratio of the electricity storage apparatus is small is prohibited when execution of control for second spot region of traveling by only a motive power from the motor by stopping the engine is presumed or planned within a predetermined distance range in a second spot region presumed or set as a spot or a region in which electrically-powered traveling of traveling by only the motive power from the motor by stopping the engine is set.
1 . A hybrid electric vehicle comprising:
a global positioning system (GPS) configured to detect a current position of the hybrid electric vehicle based on signals transmitted from GPS satellites;
a navigation system including a map information database, the navigation system being configured to plan a traveling route from the current position to a destination based on the map information database;
an engine configured to output motive power for traveling;
a motor configured to output motive power for traveling;
an electricity storage apparatus configured to exchange electricity with the motor; and
a controller configured to execute at least one of a first control associated with a first region, a second control associated with a second region, or a third control, wherein
the first control causes the hybrid electric vehicle to travel by controlling the engine and the motor such that a state of charge of the electricity storage apparatus decreases before entering the first region, the first region being a region that is preferred to be reached while the state of charge is low,
the second control causes the hybrid electric vehicle to travel using only the motive power from the motor by stopping the engine in the second region set as an electrically-powered traveling region,
the third control causes the hybrid electric vehicle to travel by controlling the engine and the motor to increase the state of charge before entering the second region, and
the controller is configured to
prohibit the first control in a case where execution of the second control is scheduled within a predetermined distance range from the current position, and
refrain from performing the second control unless the execution of the second control is scheduled within the predetermined distance range.
2 . The hybrid electric vehicle according to claim 1 , wherein the first region is a region in which stopping for a long period of time is predicted.
3 . The hybrid electric vehicle according to claim 1 , wherein:
the navigation system is configured to generate load information necessary for traveling in each traveling section of the traveling route as anticipatory information based on the map information database and road traffic information acquired from a traffic information management center; and
the controller is configured to perform at least one of the first control, the second control, and the third control based on the anticipatory information.
4 . A control method of a hybrid electric vehicle, the hybrid electric vehicle including
a global positioning system (GPS) configured to detect a current position of the hybrid electric vehicle based on signals transmitted from GPS satellites,
a navigation system including a map information database, the navigation system being configured to plan a traveling route from the current position to a destination based on the map information database,
an engine configured to output motive power for traveling,
a motor configured to output motive power for traveling,
an electricity storage apparatus configured to exchange electricity with the motor, and
a controller configured to execute at least one of a first control associated with a first region, a second control associated with a second region, or a third control, the control method comprising:
performing the first control by controlling the engine and the motor such that a state of charge of the electricity storage apparatus decreases before entering the first region, the first region being a region that is preferred to be reached while the state of charge is low;
performing the second control by traveling using only the motive power from the motor by stopping the engine in the second region set as an electrically-powered traveling region;
performing the third control by controlling the engine and the motor to increase the state of charge before entering the second region;
prohibiting the first control in a case where execution of the second control is scheduled within a predetermined distance range from the current position; and
refraining from performing the second control unless the execution of the second control is scheduled within the predetermined distance range.
