Abstract

An electrified vehicle includes: a mode switch that gives an instruction of switching being performed in order of a first mode, a third mode and a second mode, among the first mode, the second mode and the third mode; and a control device that sets a traveling mode to one of the modes in accordance with the mode switch operation and controls a motor and an auxiliary machine in accordance with the traveling mode. When the mode switch has been operated while the traveling mode is the first mode, the control device switches the traveling mode from the first mode to the second mode without the switching to the third mode, if the mode switch has been operated again within a predetermined time, and switches the traveling mode from the first mode to the third mode, if the mode switch has not been operated again within the predetermined time.

First claim

What is claimed is:

1 . An electrified vehicle including a motor for traveling, an inverter that drives the motor, an electric storage device that is connected to the inverter through an electric power line, and an auxiliary machine that is connected to the electric power line, the electrified vehicle comprising:
a mode switch that gives an instruction of switching among a first mode, a second mode and a third mode whenever the mode switch is operated by a driver, the third mode being a mode in which electric power consumption of the electrified vehicle is restricted compared to the first mode and the second mode, the switching being performed in order of the first mode, the third mode and the second mode; and a control device that sets a traveling mode to one of the first mode, the second mode and the third mode in accordance with operation of the mode switch and that controls the motor and the auxiliary machine in accordance with the traveling mode, wherein when the mode switch has been operated in a state where the traveling mode is the first mode, the control device switches the traveling mode from the first mode to the second mode without the switching to the third mode, in a case where the mode switch has been operated again within a predetermined time period, and switches the traveling mode from the first mode directly to the third mode, in a case where the mode switch has not been operated again within the predetermined time period.

2 . The electrified vehicle according to claim 1 , wherein:
the auxiliary machine is an air-conditioning device that performs air conditioning in a vehicle cabin; and the third mode is a mode in which the electric power consumption of the electrified vehicle is restricted compared to the first mode and the second mode, by execution of at least one of traveling drive power restriction, vehicle velocity restriction, and stop of the air-conditioning device.

3 . The electrified vehicle according to claim 1 , wherein:
the first mode is one mode of a normal mode, a sport mode and an ecology mode, the sport mode being a mode in which priority is given to output responsiveness of traveling drive power compared to the normal mode, the ecology mode being a mode in which priority is given to electric efficiency compared to the normal mode and the sport mode; and the second mode is one mode that is of the normal mode, the sport mode and the ecology mode and that is different from the first mode.

4 . The electrified vehicle according to claim 1 , wherein the predetermined time period starts when the mode switch is operated while the traveling mode is the first mode.

5 . The electrified vehicle according to claim 1 , wherein:
the auxiliary machine includes an air-conditioning device that performs air conditioning in a vehicle cabin, the control device controls the air-conditioning device at a first setting when the traveling mode is the first mode or the second mode, and the control device controls the air-conditioning device at a second setting different from the first setting when the traveling mode is the third mode.
