Problems solved by technology
Traditionally, the pedal force characteristics of the whole vehicle are matched on the whole vehicle, and the pedal force is determined through subjective evaluation. The system matching cycle is long and difficult to match, and the pedal force characteristic curve cannot be measured quickly and accurately.

The invention discloses a pedal force characteristic test bench which comprises the components of a test bench, a motor, a decelerator, an angle sensor, a force sensor and a mechanical arm which is used for connecting with the pedal. The motor and the decelerator are arranged on the test bench. The motor is connected with the decelerator. The angle sensor is arranged on the output shaft of the decelerator. One end of the mechanical arm is connected with an output shaft, and the other end is connected with the pedal through the force sensor. Mounting of a pedal operating mechanism on a whole vehicle is not required. A whole-vehicle environment is simulated through the bench. The characteristic of the pedal force can be quickly and accurately tested. A period in pedal system matching can be shortened, and difficulty in pedal system matching can be reduced. Furthermore the pedal force characteristic test bench has advantages of simple structure, convenient manufacture and low cost.
Description
technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a pedal force characteristic test bench in an automobile pedal control system. Background technique [0002] The pedal is the steering mechanism of the car, which directly affects people's subjective comfort and maneuverability. Traditionally, the pedal force characteristics of the whole vehicle are matched on the whole vehicle, and the pedal force is determined through subjective evaluation. The system matching cycle is long and difficult to match, and the pedal force characteristic curve cannot be measured quickly and accurately. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a pedal force characteristic test bench, so as to achieve the purpose of quickly and conveniently testing the pedal force characteristic. [0004] In order to solve the problems of the t...
