“…Great effort can be found in a summary of the research status and prospects of brake noise by Zhao. 8 Besides the above benefits, the regenerative braking provides another opportunity for automotive engineers to reduce the NVH problems in traditional frictional braking system by applying electric brake on the axle directly, rather than using hydraulic system to press the brake caliper and rotor. Complex eigenvalue analysis used in closed-loop coupling disk brake model is one of the most effective method to analyze the dynamic characteristics of brake system, which can be used to analyze the NVH in an electric and friction combined braking system in EVs.…”

Aiming at improving regenerative braking ability in electric vehicles without compromising any safety, two different regenerative braking strategies are proposed in this study. The impact of continuously varying braking force distributions between front/rear wheel and electric/friction corresponding in two different strategies on braking noise are investigated. Based on the closed-loop coupling disk brake model, the relationship between the contact coupling stiffness and the braking force is established by considering the stationary modal test, the nonlinear optimization, and the relationship between brake-line pressure and braking force. The continuously varying braking force is initially transformed to continuously varying contact coupling stiffness, then, the brake noise tendency at each frequency band is calculated in closed-loop coupled model. The predicted result shows good consistency with the result recorded in bench test, verifying the reliability and effectivity of the presented method. The comparison of the two different electric braking strategies shows that the second braking strategy is superior to the first braking strategy in terms of suppressing the brake noise tendency.
