<p>PURPOSE:To improve the resolution of recording data and to enable accurate and long time recording by recording a running state in a semiconductor memory as digital information. CONSTITUTION:In an analogue/digital (A/D) converters 31 to 34 corresponding to various kinds of running information, a various kind of running information is digitalized corresponding to the timing of a sampling cock CLK2 generated in a controller circuit 5 and the signal is outputted to a selector circuit 6. In the circuit 6, the information from the converters 31 to 34 corresponding to various kinds of running information as well as time information T from a clock circuit 4 and optional information OPD from a console 2 are received and the signal selected corresponding to a data selector signal ST from a circuit 5 is outputted as input data ID for a memory circuit 7. In the circuit 7, the input data are recorded and the output data OD are reproduced. Thus, the resolution of the recording data can be improved and the vehicle running history can be accurately recorded.</p> |
