Abstract

An electronic key system 100 for a moving body, for example an all-terrain vehicle 10, includes an electronic key 11 and a control unit 50. The electronic key 11 transmits a control code Md stored in a ROM 76. The control unit 50 reads a speed limit Vs and a power limit Ws out of one of first to fourth control mode data Md1 to Md4, which corresponds to the received control code Md, and supplies the limits to a drive control performing section 104. The drive control performing section 104 controls an engine 22 in accordance with the speed limit Vs and the power limit Ws to limit a travel speed V and power W. This renders the driving performance appropriate to the driving condition and/or the driver.

Claims

1. A moving body having a control unit that controls a driving mechanism, wherein the control unit is configured to receive a first identification signal transmitted from a portable transmitter, and when the control unit receives the first identification signal the control unit controls the driving mechanism in accordance with the first identification signal.

2. The moving body according to claim 1,

wherein the portable transmitter transmits a second identification signal for authentication and the control unit is configured to receive the second identification signal, and

the control unit includes a stored authentication code, and when the control unit receives the second identification signal the control unit enables the moving body to be activated when the stored authentication code and the received second identification signal coincide.

3. The moving body according to claim 1,

wherein the moving body includes a meter, and wherein the control unit allows the meter to display a control signal based on the received first identification signal.

4. The moving body according to claim 1,

wherein the control unit sets a travel speed limiting value to a different value in accordance with the first identification signal to control the driving mechanism.

5. The moving body according to claim 1,

wherein the driving mechanism includes a transmission, and wherein the control unit sets gear change characteristics of the transmission in the driving mechanism to different characteristics in accordance with the first identification signal.

6. The moving body according to claim 1,

wherein the driving mechanism includes a drive source, and wherein the control unit sets rotational frequency of the drive source, power thereof, or a limiting value torque of thereof, to a different value in accordance with the first identification signal.

7. An electronic key system for a moving body having a driving mechanism, comprising:

a portable transmitter configured to transmit a first identification signal; and

a control unit mounted on the moving body and configured to receive the first identification signal transmitted from the portable transmitter,

wherein the control unit controls the driving mechanism of the moving body in accordance with the received first identification signal.

8. The electronic key system for a moving body according to claim 7,

wherein the portable transmitter is configured to transmit a second identification signal for authentication,

the control unit includes a stored authentication code and the control unit is configured to receive the second identification signal for authentication, and

the control unit is configured to enable the moving body to be activated when the stored authentication code and the received second identification signal coincide.

9. The electronic key system for a moving body according to claim 7,

wherein the portable transmitter includes switching means for changing the first identification signal to be transmitted.
