本项目的目的是研究一种具有非线性控制概念的自激式电液制动器(SEHB),并根据制动动力学、制动舒适性和制动磨损的标准开发自适应阀门控制。在第二个资助期的这一应用中,摩擦力矩的变化最小。它们是摩擦系数变化的结果,并影响舒适性、动力性和耐磨性。首先,通过文献研究和试验台试验确定摩擦力矩变化发展的相关影响因素。下一步将制定措施,利用摩擦力矩的反馈来抑制摩擦力矩变化的产生机制。所开发的被动和主动措施,如优化夹紧刚度和带有在线参数估计的控制器,将在现有的制动试验台上进行验证。因此,寻求延长制动盘的使用寿命。这应该通过最小化摩擦扭矩变化来实现。由于现有的制动力矩测量和影响夹紧力的可能性,SEHB特别能够利用这一潜力。
英文摘要
Aim of this project is the research on a Self-energising Electro-Hydraulic Brake (SEHB) with nonlinear control concept and the development of adaptive valve controls with respect to the criteria brake dynamics, brake comfort, and brake wear.In this application for the second funding period friction torque variations are minimised. They occur as a consequence of friction coefficient variations und influence comfort, dynamics, and wear. At first, relevant influencing factors on the development of friction torque variations will be determined by literature research and test rig experiments. In a next step measures will be developed to make use of the feedback of the friction torque in order to damp the originating mechanisms of the friction torque variations. The developed passive and active measures, like optimisation of the clamping stiffness and a controller with online-parameter estimation, will be validated at the available brake test rig. Thereby, it is sought to prolong the brake disc lifetime. This should be achieved by the minimisation of the friction torque variations. Due to the existing measurement of the brake torque and the possibility to influence the clamping force, this potential can particularly be harnessed by the SEHB.
