## Abstract

A vehicle system is a vehicle system mountable in a hybrid vehicle, which includes an internal combustion engine, a rotary electric machine connected to an axle, and a storage battery for supplying electric power for traveling to the rotary electric machine, comprising: a display; a determiner configured to determine whether it is possible to switch from a first mode to a second mode on the basis of an SOC of the storage battery, the first mode being a mode in which electric power traveling of performing traveling by causing the rotary electric machine to drive only using electric power supplied by the storage battery, the second mode being a mode in which the electric power traveling is prioritized more than in the first mode; and a display controller configured to cause the display to display an image regarding whether switching to the second mode is possible.

## Claims

### Claim 1

A vehicle system mountable in a hybrid vehicle, which includes an internal combustion engine, a rotary electric machine connected to an axle, and a storage battery for supplying electric power for traveling to the rotary electric machine, comprising:
a display;
a determiner configured to, based on a State Of Charge (SOC) of the storage battery and at least one of a temperature of the storage battery or a cooling water temperature, determine whether a switch from a first mode to a second mode is possible, the first mode comprising electric power traveling of performing traveling by causing the rotary electric machine to drive only using electric power supplied by the storage battery without causing the internal combustion engine to operate shifted to engine operation traveling of performing traveling by causing the internal combustion engine to operate according to an increase of drive power, the second mode comprising the electric power traveling prioritized more than in the first mode;
a switcher configured to switch between the first mode and the second mode on the basis of an instruction of a driver and a determination result of the determiner; and
a display controller configured to cause the display to display an image regarding whether switching to the second mode is possible,
wherein the determiner is further configured to determine whether the switch to the second mode is possible based on a threshold value set in advance for the SOC, and
the display controller is further configured to cause the display to display an image in which the SOC of the storage battery and the threshold value can be recognized as the image regarding whether switching to the second mode is possible.

### Claim 2 (depends on 1)

The vehicle system according to claim 1,
wherein the display controller is configured to cause the display to display an image in which the threshold value is represented in a switching portion of a display form in a graph in which the SOC is displayed.

### Claim 3 (depends on 1)

The vehicle system according to claim 1,
wherein the determiner is configured to adjust the threshold value on the basis of at least one of a temperature of the storage battery or a cooling water temperature.

### Claim 4 (depends on 1)

The vehicle system according to claim 1,
wherein the determiner is configured to sequentially determine whether switching to the second mode is possible on the basis of an SOC of the storage battery and at least one of a temperature of the storage battery or a cooling water temperature.

### Claim 5 (depends on 1)

The vehicle system according to claim 1,
wherein the display controller is configured to cause the display to display the image regarding whether switching to the second mode is possible regardless of whether there is an instruction to switch to the second mode.

### Claim 6 (depends on 1)

The vehicle system according to claim 1,
wherein, in a case where switching to the second mode is not possible, the display controller is configured to cause the display to display an image indicating a reason why the switching is not possible.

### Claim 7 (depends on 6)

The vehicle system according to claim 6,
wherein the display controller is configured to cause the display to display the image indicating a reason why the switching is not possible in a case where there is an instruction to switch to the second mode and switching to the second mode is not possible.

### Claim 8 (depends on 1)

A hybrid vehicle in which the vehicle system according to claim 1, the internal combustion engine, the rotary electric machine connected to the axle, and the storage battery that is configured to supply electric power for traveling to the rotary electric machine are mounted.
