Various embodiments relate to a system and related method of validating a distance based on a plurality of sensor measurements in a vehicle. A tamper-proof odometer system may comprise an odometer and a tamper-proof sensor that independently determine dist...

To simply display 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. A mileage display system (10) includes a contr...

The monotonic counter is implemented as an integrated circuit where each counting bit (B1,B2,B3,B4) is provided by a memory cell (11) containing at least one memory element constituted of a resistor of polycrystalline silicon which is programmable by an ir...

A signal acquisition section 19 acquires, for example, a vehicle velocity pulse signal, which is generated from a vehicle velocity sensor 8 in accordance with the movement of a vehicle that is a mobile body. A distance information acquisition section 20 ac...

The distance data recording method uses a data bus (5) for supplying the distance data provided by a distance recording device (2) to two control devices (1,6). Each device records the distance data in an associated memory (4,7). Each control device suppli...

There are included a sensor 310 which outputs pulse signals corresponding to the traveling distances of a vehicle, a vehicle display device 100 which displays, based on the pulse signals, vehicle information including the traveling distance, and a navigati...
