Abstract: With the increasing demand of consumers for pedal feeling and the attention of OEMs to the development of pedal feeling, the traditional mode has been unable to meet needs for the development of new braking system. Combined with the actual experience, this paper provides new ideas to solve the current contradictions. Combined with the characteristics of the braking system of battery electric vehicles, this paper compares and analyzes the differences with the traditional braking system, and then, introduces the evaluation conditions of brake pedal feeling and the contents of subjective and objective evaluation. The influencing factors and key parameters of the pedal feeling as well as the precautions in the development are clarified. Combined with the actual project experience, the development process of the brake pedal feeling and the key tasks in each stage are summarized. Finally, an example is given to illustrate the whole development process of brake pedal feeling, which provides experience accumulation for the development and improvement of brake pedal feeling in the future.
