Abstract

An ECU executes a program including the steps of: performing shipping electric charging control when an electric charging plug is connected and a condition is also established for performing the shipping electric charging control; and if the condition for performing the shipping electric charging control is not established, performing full electric charging control.

Claims

1. A vehicular control device for use in a vehicle by a user, the vehicle including:

(i) a rotating electric machine configured as a driving source, (ii) a plurality of power storage devices for supplying said rotating electric machine with electric power, and (iii) an electric charging device configured to electrically charge said plurality of power storage devices from an external power supply, said plurality of power storage devices being connected in parallel, the vehicular control device comprising;

an input device configured to input an instruction of the user of said vehicle based on an operation to any one of;

(1) a brake pedal, (2) an acceleration pedal, and (3) a steering wheel; and

an electronic control unit configured to perform;

a first electric charging control for electrically charging said plurality of power storage devices to have a state of charge to attain an electrically fully charged state in response to connecting said external power supply to said electric charging device, and

a second electric charging control in response to connecting said external power supply to said electric charging device and receiving an instruction from the input device by the user to perform said second electric charging control, said second electric charging control including electrically charging each power storage device by the external power supply to have a state of charge equal to a threshold value smaller than an upper limit value set for a state of charge corresponding to said electrically fully charged state.

2. The vehicular control device according to claim 1, wherein

when:

(i) said external power supply is connected to said electric charging device and (ii) said instruction is input to said input device for performing said second electric charging control, said electronic control unit electrically charges a first power storage device of said plurality of power storage devices via said external power supply, and

when said first power storage device attains a state of charge equal to or larger than said threshold value, said electronic control unit electrically charges a second power storage device different from said first power storage device to attain a state of charge equal to or larger than said threshold value via said external power supply.

3. The vehicular control device according to claim 1, wherein:

said input device includes;

a detector configured to detect an amount of an operation of said brake pedal; and

said electronic control unit performs said second electric charging control when;

(i) said external power supply is connected to said electric charging device, and (ii) the brake pedal is depressed and released for a predetermined number of times within a predetermined period of time as detected by the detector.

4. The vehicular control device according to claim 1, wherein:

a connection terminal is attached to said vehicle for connecting said external power supply to said electric charging device;

said input device includes;

a button provided at said connection terminal for unlocking and thus disconnecting said external power supply from said electric charging device, and

a detector for detecting whether said button has been operated; and

said electronic control unit performs said second electric charging control in response to;

(i) said external power supply is connected to said electric charging device, and (ii) how many times said button is operated within a predetermined period of time for a predetermined number of times, based on a result detected by said detector.

5. The vehicular control device according to claim 1, wherein said second electric charging control is performed when said vehicle is shipped from a factory.

6. A vehicular control method for use in a vehicle by a user, the vehicle including:

(i) a rotating electric machine configured as a driving source, (ii) a plurality of power storage devices configured to supply said rotating electric machine with electric power, and (iii) an electric charging device configured to electrically charge said plurality of power storage devices from an external power supply, said plurality of power storage devices being connected in parallel, the method comprising the steps of;

receiving an instruction from the user of said vehicle based on an operation to any one of;

(1) a brake pedal, (2) an acceleration pedal, and (3) a steering wheel; and

performing a first electric charging control for electrically charging said plurality of power storage devices to have a state of charge corresponding to an electrically fully charged state in response to connecting said external power supply to said electric charging device, and

performing a second electric charging control in response to the external power supply being connected to said electric charging device and receiving an instruction from the user to perform said second electric charging control, said second electric charging control including electrically charging each power storage device by the external power supply to have a state of charge equal to a threshold value smaller than an upper limit value set for a state of charge corresponding to said electrically fully charged state.
