As Chinese vehicle market approaches saturation,customer propose higher expectation towards the vehicle performance and quality.The previous design approaches to merely pass the regulation would fail to provide satisfying experience in the future.Thus it is of significance to realize autonomous vehicle development process targeting at customer request.More advanced vehicle developing technology is necessary for the improvement of the traditional vehicle development process.For further acceleration,objective analysis and quantitative specification are beneficial as foundation of practical improvement solutions.The objective target can be determined by subjective evaluation process reflecting customer riding experience.The vehicle performance can be improved through the obtained objective target to compensate the limitation of a subjective evaluation process.Therefore the consistency among development process,objective analysis and subjective evaluation is vital to vehicle performance design.This paper focuses on the brake pedal feeling analysis in the scope of the vehicle chassis evaluation.A customer-based subjective evaluation process towards brake pedal feeling is developed,as well as an objective analysis process established on brake system theories.The correlation between the two processes is studied and validated through subjective ratings and experimental results of a series of vehicle.Finally,according to the subjective and objective evaluation process of vehicle brake system,transformation towards a specific vehicle braking system is conducted.The difference are recorded as a validation to the proposed evaluation processes.The subjective and objective evaluation processes proposed in the paper are practical and of guidance.It has been applied as a standard in Beijing Automotive Technology Center,and can serve as reference for other companies.
