A mileage display system includes a control unit operatively connected to an ignition switch of a motorcycle that obtains the accumulated mileage by accumulating a pulse signal produced according to running of the motorcycle. The control unit records odometer data in an EEPROM. The control unit also reads the odometer data recorded in the EEPROM when the ignition switch is operated. If the odometer data exceeds the maximum value to be displayed on an odometer (for example, 99999), the control unit displays on the odometer for a predetermined period of time a numeric value of digits of higher order than the predetermined number of display digits of the odometer data. The mileage display system displays an accurate, accumulated distance traveled or accumulated mileage, after the mileage overflows by exceeding a maximum display value as established by a predetermined number of display digits.

Odometer system and method for a vehicle

To provide a fuel pump control device allowing a fuel pump having a small capacity to feed a sufficient amount of fuel to an internal combustion engine. During running of a vehicle at a low speed (for example, less than 2,0 km/hr), pulsed drive voltages are intermittently supplied to a fuel pump in accordance with each opening/closing of a thyristor on the basis of ignition pulses of the engine. In this way, the fuel pump repeats discharge operation at a relatively long cycle in synchronization with the pulsed drive voltages. During running of the vehicle at a high speed, a drive voltage is continuously supplied (that is, a DC voltage is supplied) from a power supply line to the fuel pump, whereby the fuel pump repeats discharge operation at a cycle with a short self-excitation state.
