Description

technical field [0001] The invention relates to the technical field of automobile testing. Background technique [0002] The pedal of a car is one of the important parts for manipulating a car. The pedal characteristic is an important index to evaluate the car's handling performance, and an important parameter for analyzing the pedal characteristic is the pedal stroke. The mainstream pedal stroke test at home and abroad uses a drawstring displacement sensor to indirectly measure the pedal stroke. Some domestic companies test the pedal stroke with an angle sensor through a four-bar linkage mechanism. Its shortcomings: complex installation, large space required, and high technical requirements for testers. Contents of the invention [0003] The object of the present invention is to provide an automobile pedal stroke testing device and method with convenient installation, simple structure, small size and high testing accuracy. [0004] The automobile pedal stroke testing d...
