PURPOSE:To enable easy reproduction of necessary data alone by generating a timing signal in response to braking operation, performing data processing based thereon and recording data in a plurality of braking operations together. CONSTITUTION:A distance pulse signal from a distance sensor 1, a clock signal from a clock circuit 2, a gradient signal from a gradient detector 3 and the braking switch signal from a braking switch 4 are given to an operation processing parts 5 and the data such as the initial speed at the time of start of braking, the final speed of braking at the time of completion of braking, the distance of running (braking distance) and time of running (braking time) while braking being applied and the integrated distance and time of running are subjected to operation processing and indicated in an indication part 6, while they are memorized sequentially in a memory part 7 prepared by using sixteen units of semiconductor memory elements as a recording means. |
