<p>PROBLEM TO BE SOLVED: To automatically record traveling states (such as running, a resting, stand-by loading. SOLUTION: In this tachograph provided with a seat switch to detect a seating state, an ignition switch to detect the operation state of an engine, a speed sensor to detect vehicle speed, an opening/closing switch to detect opening/closing states of a door of a loading space, a time detection mechanism to detect the present time and a memory card in which rest time is set, the running state is estimated as the 'running' (a state (1)) when a driver is seated on a driver's seat, the engine is operated and the vehicle speed is not zero; the running state is estimated as the 'rest' (states (2) (4) (7)) when the driver is seated on the driver's seat, the engine is operated and the vehicle speed is zero, when the driver is seated on the driver's seat, the engine is stopped or when the driver is not seated on the driver's seat and the door of the carrier is closed and the driver is in rest time; and the running state is estimated as the 'stand-by loading' (state (3) (5) (8)) when the driver is out of the rest time. The running state is speculated as a 'loading/unloading' (a state (6)) when the driver is not seated on the driver's seat and the door of the carrier is opened; then the estimated result is recorded together with the time.</p> |
