PURPOSE:To record and analyze the operation state of a car precisely and detailedly by storing micro and macro data, and when abnormal acceleration/deceleration is detected, storing the detected contents and printing out the stored contents. CONSTITUTION:A storage device 12 stores an average speed 100 and an average car speed v1 and a travelling distance s1 for a short period outputted from a travelling distance detecting part 102 as micro data. Receiving the data v1, s1, a storage device 14 calculates an average speed v2 and a travelling distance s2 for a sufficiently long period and stores these data sa macro data. An acceleration detector 104 is connected to the device 12, and when a car in operation clashes against another car or another car dashes against the car in operation from behind, the detector 104 senses and decides the abnormal acceleration/ deceleration an sends the signal to the device 12 and a printer 18 prints out the stored contents forcedly. |
