An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

速、逆ならば減速と判定させている。 FIG. 1 is an overall configuration diagram of the device according to this embodiment, and a pulse transmitter 1 is attached to a vehicle, which outputs a number of pulses proportional to the specific speed of the vehicle. A microcomputer 4 (hereinafter simply referred to as microcomputer) counts the number of pulses every unit time (0.5 s ) and calculates the current speed of the vehicle. Therefore, when the power is turned on and the microcomputer starts operating, it reads the speed setting values 2 and 3, counts the number of pulses from the pulse generator 1, calculates it in the speed calculation section 5, and sends the calculation result to the LED 8 and printer 9. It is output through the output calculation section 6. Since the microcomputer 4 only has inputs as the speed signal from the pulse transmitter 1 and the outputs from the upper and lower limit speed setters 2 and 3, it is necessary to judge acceleration and deceleration from the speed signal. The program in 4 compares the current speed with that of a few seconds ago, and if the average difference is positive, it is determined to be an acceleration, and if it is the opposite, it is determined to be a deceleration.

したものである。 In addition, if the above judgment is positive, the performance calculation program set in the microcomputer 4 starts the performance calculation program when the detected speed of the pulse generator 1 matches the set lower limit speed, and checks if the detected speed matches the upper limit speed. Stop when you do. If the above determination is negative, the performance calculation program is started and stopped in the opposite manner, the average acceleration is calculated, and the result is displayed on the printer 9. Figure 2 shows
The lower limit speed during acceleration is set to 10Km/H and the upper limit speed is set to 10Km/H.
Set to 30Km/H and set the upper limit speed during deceleration to 28
The microcomputer 4 executes the performance calculation program when the lower limit speed is set to 5 Km/H. The speed curve shows the execution start points X 1 and X 3 and the execution stop points X 3 and X 4 .

Km／Ｈ）は停止動作の速度よりも高く定める。 The upper and lower limits of the speed measurement range during acceleration and the upper and lower limits of the measurement range during deceleration will be explained. As a result of various studies by the inventor, it was discovered that the speed is not constant for a predetermined period immediately after the start of acceleration and immediately after the start of deceleration, and that there is an unstable region. Based on this knowledge, the speed of only the stable speed region excluding the unstable region is calculated and output, so that the desired performance can be easily determined. For this purpose, a lower limit value and an upper limit value of the speed range for determining performance during acceleration are set. The calculated value of the speed is not output below the lower limit value (10 Km/H) immediately after the start of acceleration. The upper limit (30 km/h) is set below the speed of constant speed driving. On the other hand, during deceleration, the upper limit and lower limit are similarly limited. The upper limit during deceleration (28Km/H) is set lower than the speed immediately after deceleration starts. Lower limit value during deceleration (5
Km/H) is set higher than the speed of the stopping operation.
