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.

本项目的目的是研究具有非线性控制概念的自激励电液制动器（SEHB），并根据制动动力学、制动舒适性和制动器磨损标准开发自适应阀控制。在第二个资助期内，该应用将摩擦扭矩变化降至最低。它们是摩擦系数变化的结果，影响舒适性、动力学和磨损。首先，通过文献研究和试验台试验，确定摩擦扭矩变化发展的相关影响因素。在下一步中，将开发措施以利用摩擦扭矩的反馈，以便阻尼摩擦扭矩变化的起源机制。所开发的被动和主动措施，如夹紧刚度的优化和具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。由于现有的制动扭矩测量和影响夹紧力的可能性，SEHB特别可以利用这种潜力。
