Abstract

PURPOSE: To make a dynamic diagnosis by simple facility by detecting a rotational frequency by letting the braking load of a brake operated temporarily on engine power, and also by detecting the braking force load of the brake from treading force against a brake pedal.
CONSTITUTION: Driving wheel 5 of automobile 4 is made in contact with rotary drums 2 and 3 of brake tester 1 to force driving wheel 5 to turn and treading force against brake pedal 8 when brake pedal 8 is trod is electrically extracted via treading force sensor 9 and then inputted to microcomputer 11. Simultaneously, the braking force load of a brake on driving wheel 5 is extracted by torque gauge 12 and inputted to microcomputer 11 via electric converter 14 to store the relation between the treading force and braking force load. Next, driving wheel 5 is mounted on rotary drums 17 and 18 of speedmeter tester 16 and the engine is driven to perform calculation processing using the rotational frequency and the above-mentioned relation, thereby measuring dynamic output characteristics.
