ABSTRACT:
A motor vehicle driving analytically diagnosing device comprises: running speed detecting means for detecting a running speed of a motor vehicle; acceleration detecting means for detecting acceleration of the motor vehicle; braking detecting means for detecting braking of the motor vehicle; a detected signals analyzing unit for analyzing a running speed signal detected by the running speed detecting means, an acceleration signal detected by the acceleration detecting means and a braking signal detected by the braking detecting means to generate analyzed signals indicative of driving states of a driver; a dangerous driving times counting unit for counting dangerous driving times during which the analyzed signals generated by the detected signals analyzing unit satisfy predetermined danger judging conditions in a certain period of driving, and for detecting maximum values of the analyzed signals generated by the detected signals analyzing unit in the certain period of driving; and a driving diagnosing unit for diagnosing driving of a driver, based on ratios of the periods of dangerous driving to the certain period of driving time and the maximum values of the analyzed signals. Driving states of a motor vehicle can be accurately provided in detail, and driving patterns of the driver can be analytically diagnosed accurately.
