a first on-vehicle switch; and

a second on-vehicle switch located at a position farther from the on-vehicle reception unit than the first on-vehicle switch,

wherein the on-vehicle apparatus control system further comprises a level switch that switches transmission intensity of a signal transmitted from the portable machine transmission unit, or reception sensitivity of a signal received by the on-vehicle reception unit,

wherein in a case where the first on-vehicle switch is operated, the level switch switches the transmission intensity or the reception sensitivity to a first level, and

wherein in a case where the second on-vehicle switch is operated, the level switch switches the transmission intensity or the reception sensitivity to a second level higher than the first level.

2. The on-vehicle apparatus control system according to claim 1 ,

wherein the portable machine further comprises a portable machine switch that operates the on-vehicle apparatus, and causes the portable machine transmission unit to transmit a remote control signal when the portable machine switch is operated,

wherein the on-vehicle control device causes the on-vehicle reception unit to receive the remote control signal, and controls the on-vehicle apparatus on a basis of the remote control signal, and

wherein during a normal time in which the on-vehicle switches are not operated, the level switch switches the transmission intensity or the reception sensitivity to a third level higher than the second level.

3. An on-vehicle control device mounted on a vehicle, the on-vehicle control device comprising:

an on-vehicle transmission unit; and

an on-vehicle reception unit,

wherein in a case where one of a first on-vehicle switch disposed on an outer surface of the vehicle and a second on-vehicle switch disposed on the outer surface of the vehicle and farther from the on-vehicle reception unit than the first on-veil/de switch is operated,

the on-vehicle transmission unit transmits a response request signal to a portable machine carried by a user, and

the on-vehicle reception unit receives a response signal transmitted from the portable machine in response to reception of the response request signal in the portable machine, and an on-vehicle apparatus mounted on the vehicle is controlled on a basis of the response signal, and

wherein in a case where the first on-vehicle switch is operated, transmission intensity of a signal transmitted from the portable machine or reception sensitivity of a signal received by the on-vehicle reception unit is set to a first level, and

wherein in a case where the second on-vehicle switch is operated, the transmission intensity or the reception sensitivity is set to a second level higher than the first level.

4. The on-vehicle control device according to claim 3 ,

wherein the on-vehicle transmission unit transmits the response request signal to the portable machine:

in a case where the first on-vehicle switch is operated, the response request signal comprising information for recognizing the first on-vehicle switch so as to allow the portable machine to set signal transmission intensity to a first level; and

in a case where the second on-vehicle switch is operated, the response request signal comprising information for recognizing the second on-vehicle switch so as to allow the portable machine to set signal transmission intensity to a second level higher than the first level.

5. The on-vehicle control device according to claim 3 , further comprising:

a level switch that switches reception sensitivity of a signal received by the on-vehicle reception unit,

wherein in a case where the first on-vehicle switch is operated, the level switch switches the reception sensitivity to a first level, and

wherein in a case where the second on-vehicle switch is operated, the level switch switches the reception sensitivity to a second level higher than the first level.

6. The on-vehicle control device according to claim 5 ,

wherein in a case where a portable machine switch disposed in the portable machine is operated, the on-vehicle reception unit receives a remote control signal transmitted from the portable machine, and the on-vehicle apparatus is controlled on a basis of the remote control signal, and

wherein during a normal time in which the first on-vehicle switch and the second on-vehicle switch are not operated, the level switch switches the reception sensitivity to a third level higher than the second level.

7. A portable machine carried by a user, the portable machine comprising:

a portable machine transmission unit; and

a portable machine reception unit,

wherein in a case where one of a first on-vehicle switch disposed on an outer surface of a vehicle and a second on-vehicle switch disposed on the outer surface of the vehicle and farther from an on-vehicle reception unit than the first on-vehicle switch is operated,

the portable machine reception unit receives a response request signal transmitted from an on-vehicle control device mounted on the vehicle, and

the portable machine transmission unit transmits a response signal to the on-vehicle control device so as to allow the on-vehicle control device to control an on-vehicle apparatus mounted on the vehicle,

wherein the portable machine further comprises a level switch that switches transmission intensity of a signal transmitted from the portable machine transmission unit,

wherein if the portable machine reception unit receives the response request signal from the on-vehicle control device, information included in the response request signal for recognizing an operated on-vehicle switch is referred to,

wherein in a case where the operated on-vehicle switch is the first on-vehicle switch, the level switch switches the transmission intensity to a first level, and

wherein in a case where the operated on-vehicle switch is the second on-vehicle switch, the level switch switches the transmission intensity to a second level higher than the first level.

8. The portable machine according to claim 7 , further comprising:

a portable machine switch which operates the on-vehicle apparatus,

wherein in a case where the portable machine switch is operated, the portable machine transmission unit transmits a remote control signal to the on-vehicle control device so as to allow the on-vehicle control device to control the on-vehicle apparatus, and
