## Abstract

In a vehicular portable device, a display unit is controlled to display an icon representing an instruction to an in-vehicle device when detecting that an acceleration equal to or greater than an activation threshold occurs in the vehicular portable device, a pressing force at an icon selection position, which is a position where the icon is selected by a touch sensor, is detected, and a control signal instructing execution of a command corresponding to the icon being selected is transmitted based on detection of the pressing force in a state where the icon is selected.

## Claims

### Claim 1

A vehicular portable device to be carried by a user of a vehicle and configured to transmit a control signal to an in-vehicle device mounted on the vehicle, the vehicular portable device comprising:
an acceleration sensor;
a display unit that displays an icon representing an instruction to the in-vehicle device;
a display control unit that controls the display unit to display the icon when detecting that an acceleration equal to or greater than an activation threshold occurs in the vehicular portable device based on a signal output from the acceleration sensor;
a touch sensor to select the icon displayed on the display unit;
a pressure sensor that detects a pressing force at an icon selection position, which is a position where the icon is selected by the touch sensor; and
a transmission control unit that transmits a control signal instructing execution of a command corresponding to the icon being selected based on detection of the pressing force by the pressure sensor in a state where the icon is selected.

### Claim 2 (depends on 1)

The vehicular portable device according to claim 1, wherein
the touch sensor is a capacitive touch sensor.

### Claim 3 (depends on 2)

The vehicular portable device according to claim 2, wherein
the capacitive touch sensor used as the touch sensor is a first capacitive touch sensor,
the vehicular portable device further comprises a second capacitive touch sensor that is disposed to a rear side of the first capacitive touch sensor, and
the pressure sensor includes the first capacitive touch sensor and the second capacitive touch sensor.

### Claim 4 (depends on 3)

The vehicular portable device according to claim 3, wherein
the display unit displays a plurality of the icons at different positions, and
the second capacitive touch sensor has detection regions, the number of which is less than the number of the icons that are displayed.

### Claim 5 (depends on 1)

The vehicular portable device according to claim 1, wherein
the display control unit turns off the display unit based on transmission of the control signal by the transmission control unit.

### Claim 6 (depends on 1)

The vehicular portable device according to claim 1, wherein
the display unit includes a display region that indicates transmission of the control signal when the control signal is transmitted at a position different from the icon.

### Claim 7 (depends on 1)

The vehicular portable device according to claim 1, wherein
the acceleration sensor, the display unit, the touch sensor, the pressure sensor, and the transmission control unit are connected to the display control unit.

### Claim 8 (depends on 1)

The vehicular portable device according to claim 1, wherein
each of the display control unit and the transmission control unit includes a processor and a memory.

### Claim 9 (depends on 1)

The vehicular portable device according to claim 1, wherein
the transmission control unit transmits the control signal instructing execution of the command corresponding to the icon being selected when the pressor sensor detects that the pressing force at the icon selection position continues for a predetermined time in the state where the icon is selected.
