Problems solved by technology

However, most of the current brake detection is to check the braking distance, and the detection of the accelerator is basically not
These inspections basically cannot effectively find the quality or design hidden dangers of brakes and accelerators. In fact, there are basically no reports of problems found in such daily inspections.

Abstract

The invention discloses a detection system for fatigue-resistant performances of an automobile brake and an accelerator. The detection system comprises an automatic pedal device, a driving wheel traveling device, a data acquisition unit and a computer, wherein driving wheels of a vehicle to be detected travel on the driving wheel traveling device, the automatic pedal device is arranged in an automobile cab, the computer is connected with the automatic pedal device and the data acquisition unit respectively, the automatic device steps an accelerator pedal and / or a brake pedal of the automobile repeatedly according to parameters set by the computer, and the data acquisition unit sends acquired test data to the computer for analysis processing simultaneously. The detecting system has the advantages of being simple in structure and capable of detecting fatigue-resistant performances of automobile brakes and accelerators under various driving environments.

Description

technical field [0001] The invention relates to the field of automobile detection, in particular to a detection system for detecting the fatigue resistance performance of a brake system and an accelerator system of an automobile. Background technique [0002] Toyota recalls 8.5 million vehicles worldwide over 'pedal door' incident According to documents Toyota provided to NHTSA, the defective gas pedal actually had two separate defects. One is the slow reset of the accelerator pedal in Toyota Tundra and other models, which was confirmed in early 2008. Another flaw is a sticking gas pedal problem in 2.3 million recalled vehicles. 410,000 vehicles were recalled in the United States due to hidden dangers in the braking system of Honda vehicles. On the afternoon of March 16, 2010, Honda announced that it would recall 410,000 Honda vehicles in the United States. In recent years, there have been more and more vehicle recalls due to brake system problems and accelerator system p...
