PURPOSE:To achieve the performance test of a running body accurately and efficiently by handling items from the measurement of speed to the calculation of an average acceleration with a computer only if the upper and lower limit speeds are set. CONSTITUTION:A pulse transmitter 1 is mounted on a vehicle to output the number of pulses proportional to the intrinsic speed thereof and the number of pulses is counted with a microcomputer 4 in terms of each unit time to calculate the current speed of the vehicle. The set speed values of upper/lower limits setting devices 2 and 3 are read out while the number of pulses from the pulse transmitter 1 is counted and undergoes a calculation with a speed computing section 5 and the results of calculation are outputted to an LED 8 and a printer 9 through an output arithmetic section 6. The current speed is compared with the speed several sec. before on a program in the microcomputer 4 and acceleration is given by judgement when the average of the differences therebetween is plus while deceleration when it is minus. When the average of the differences is plus, the performance calculation program is started upon the coinciding of the current speed with the set lower limit and stopped upon the coinciding thereof with the set upper limit. |
