Electro-Mechanical Brake (EMB) system, which has the advantages of no liquid medium, fast braking response and complete decoupling, etc., could meet the functional requirements of autonomous vehicle such as high-quality active braking and high-intensity regenerative braking. Therefore, the EMB is considered to be one of the ideal carriers of future vehicle chassis. However, when the EMB receives time-varying braking requirements in different working conditions, the traditional clamping force control strategy with fixed control parameters is difficult to maintain high-quality braking performance. At the same time, the nonlinear friction resistance between transmission mechanisms also affects the accuracy of clamping force controller. This paper presents an adaptive clamping force control strategy for EMB considering nonlinear frictional resistance.
