<p>PURPOSE:To record accurate data independently of the drive speed of a vehicle. CONSTITUTION:Sensors 34, 36,... detecting the drive state of a vehicle are connected to a CPU 14 of a driver recorder 10 and a data recorder 12 recording data from the sensors 34, 36,... is provided. The rotation of a rotor 22 rotated integrally with wheels is detected by a pickup sensor 24 and a comparator 30 discriminates whether or not the vehicle runs a prescribed distance and a sampling signal used to record data sensed by the sensors 34, 36,... to the data recorder 12 is outputted to the CPU 14. Thus, the data are sequentially recorded at a sampling interval changed depending on the drive speed of the vehicle to the data recorder 12.</p> |
