Patent ID: 7626494

Claim:
A moving body, comprising: a monitor, including: a speed meter, a speed limit meter that displays travel speed limiting values, and a power limit meter that displays power limit values; and a control unit that controls a driving mechanism, wherein the control unit is configured to receive first identification signals transmitted from respective first and second portable transmitters, wherein at least one of the portable transmitters includes: a battery, a memory that stores a plurality of first identification codes, a transmitting circuit, a power circuit that supplies electric power from the battery to the transmitting circuit, and a switch configured to select a selected first identification code from the plurality of the first identification codes, wherein each of the plurality of first identification codes correspond to a predetermined value for a parameter of the control unit, wherein when one of the first identification codes is selected, the first identification signal transmitted from the portable transmitter corresponds to the selected first identification code, wherein when said first identification signals are received by the control unit, the control unit controls the driving mechanism in accordance with the first identification signal which is associated with a lower travel speed limiting value and a lower power limit value; wherein at least one of the portable transmitters transmits a second identification signal for authentication and the control unit is configured to receive the second identification signal, wherein 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, and wherein the control unit allows the monitor to display the lower travel speed limiting value and the lower power limit value based on the received first identification signals.
