Abstract

The invention provides a testing device for the feel of a brake pedal. The testing device comprises a test board, a braking system, an electric loading device, a vacuum system, a filling system, and adata acquisition and processing system, wherein the brake system, the electric loading device, the vacuum system, the filling system and the data acquisition and processing system are arranged on thetest board respectively; the braking system comprises a brake pedal assembly, a brake master cylinder, a vacuum booster assembly, an electronic stabilization system and a plurality of brakes, whereinthe brake master cylinder and the vacuum booster assembly are connected with the brake pedal assembly, the electronic stabilization system is connected with the brake master cylinder and the vacuum booster assembly through a brake pipeline, and the plurality of brakes are respectively connected to the electronic stabilization system through a brake pipeline; the vacuum system and the filling system are respectively connected with the brake master cylinder and the vacuum booster assembly; the electric loading device is abutted against a brake pedal of the brake pedal assembly, and the data acquisition and processing system is electrically connected with the electric loading device, the vacuum system and the filling system respectively. According to the testing device for the feel of the brake pedal provided by the invention, filling of braking liquid can be automatically completed, so that manual filling of the braking liquid is avoided.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a testing device for brake pedal feeling. Background technique [0002] The braking system is an important safety guarantee for a car, and the feel of the brake pedal, as one of the important qualities of a car, directly affects consumers' overall evaluation of the car. At present, the matching of brake pedal feeling by most OEMs mainly goes through the following two stages: one is the preliminary theoretical matching design, and the other is the actual vehicle test. Re-testing the real vehicle will not only waste manpower and material resources, but also take a long time; if the brake system pedal feeling test bench is used for simulation testing and optimization before the real vehicle test, it will save costs and shorten the braking system time. matching development cycle. [0003] At present, the existing test bench for testing the brake pedal feel of passenger cars can simpl...
