Abstract

A control apparatus of a hybrid electric vehicle sets ON a motor traveling history when a place within a predetermined distance range from a motor traveling spot is reached and traveling is started by a motor traveling mode, and performs control such that traveling is performed by the motor traveling mode when a motor traveling history is ON when a system is activated.

Claims (19)

1 . A hybrid electric vehicle, comprising:

an engine capable of outputting motive power for traveling;

a motor capable of outputting motive power for traveling;

a battery capable of exchanging electricity with the motor;

an ignition switch for activating a system of the hybrid electric vehicle;

a map information database that stores map information; and

a processor that is configured to perform, when the processor controls the engine and the motor by switching between a motor traveling mode that performs motor traveling that travels by the motive power from the motor in a state in which operation of the engine is stopped and a normal traveling mode that performs normal traveling that travels by the motive power from the engine and the motive power from the motor as needed, control such that traveling is performed by the motor traveling mode within a predetermined distance range from a motor traveling spot set on the map information, wherein

the processor is configured to:

set ON a motor traveling history when a place within the predetermined distance range from the motor traveling spot is reached and traveling is started by the motor traveling mode;

determine whether the motor traveling history is ON when the ignition switch is turned ON after being turned OFF; and

perform control such that traveling is performed by the motor traveling mode in a case where the processor determines that the motor traveling history is ON.

2 . The hybrid electric vehicle according to claim 1 , wherein the processor is further configured to:

store a traveling distance of a predetermined period of time from when the motor traveling spot is reached; and

perform control such that traveling is performed by the motor traveling mode for at least the traveling distance from a spot at which the system is activated in the case where the processor determines that the motor traveling history is ON.

3 . The hybrid electric vehicle according to claim 2 , wherein the processor is further configured to turn the motor traveling history OFF and ends the motor traveling mode even when a distance equal to or more than the traveling distance is not traveled by the motor traveling mode in a case where the processor determines that the motor traveling history is ON and a predetermined cancellation condition is met.

4 . The hybrid electric vehicle according to claim 3 , wherein the predetermined cancellation condition includes at least one of a first condition in which it is determined that the motor traveling spot has been passed through and a second condition in which a driver has given a request to end the motor traveling mode.

5 . The hybrid electric vehicle according to claim 1 , wherein the processor is further configured to

stop the motor traveling mode while maintaining the motor traveling history ON when at least one of a first case in which a predetermined vehicle speed or more is reached and a second case in which an electricity accumulation ratio of the battery becomes less than a predetermined ratio is established when the motor traveling mode is performed in accordance with the motor traveling history being ON, and

then restart the motor traveling mode when a speed less than the predetermined vehicle speed is reached or the electricity accumulation ratio of the battery becomes equal to or more than the predetermined ratio in a state in which the motor traveling history is ON.
