Problems solved by technology

[0004] The purpose of the present invention is to overcome and solve the test of the driving power value of the existing automobile driving conditions by using the simulation test on the automobile chassis dynamometer, which has the disadvantages of inconvenient operation, untrue and inaccurate measurement results, and large investment in test equipment. Disadvantages and problems, provide a driving power value test system for driving conditions of automobiles with many advantages such as convenient test operation, low test cost, no need for simulation test, real measurement results, accurate test results, good repeatability, and less equipment investment. Test method to promote the development of vehicle performance test technology

Abstract

A system for measuring the drive power of car is composed of rotation speed sensor, drive shaft's torque measuring unit with infrared emitter, infrared receiver, data processing device, transmission lines and accumulator. Its measuring method features that the torque and rotation speed of drive shaft are simulataneously measured and then used to calculate the drive power of car. Its advantages are less investment in equipment and high correctness.

Description

(1) Technical field: [0001] The invention relates to a driving power value testing system and a testing method thereof under driving conditions of an automobile, belonging to vehicle performance testing technical equipment. (two) background technology: [0002] The existing test system for the driving power value of a car is a car chassis dynamometer installed indoors. To test the driving power value of the car on the chassis dynamometer, the roller of the chassis dynamometer is used to replace the road surface, and the driving wheel of the car to be tested is used to drive the roller to rotate, and the roller is connected in series with the eddy current brake, which is controlled by the tester The cabinet operates the eddy current brake to apply a rotational resistance torque to the drum. When the driving wheel of the tested vehicle drives the drum of the chassis dynamometer to rotate, it must overcome the rotational resistance torque on the drum. According to the principle...
